Training a Diabetic Drill (Mandrillus leucophaeus) to Accept Insulin Injections and Venipuncture

Gary M. Priest
Zoological Society of San Diego


The drill (Mandrillus leucophaeus), is an endangered species of baboon. No population estimates exist for the animal in the wild (Oates, 1985), but it is considered one of the most threatened of all the African primates, and one of the most critically endangered primate species in the world (Lee, et al., 1988). A forest dweller and the most arboreal of all the baboons, the drill's range is now restricted to a small area on the west coast of equatorial Africa in Angola and Cameroon. Outside zoos, the only protected population is in the Korup Reserve in Cameroon.

As with nearly all animals inhabiting the tropical forests of the world, loss of habitat due to expanding human populations is placing pressure on drill populations. The forested areas, prime drill habitat, are being cleared for plantations and slash and burn agriculture Additionally, drills are shot as agricultural pests as well as hunted for meat (Gartlan, 1970). These and other factors threaten the drill with extinction in the wild before the end of this century.

Drills have been kept in captivity in European zoos since 1807 The San Diego Zoo maintains four animals (1.3), and there are fewer than 60 in captivity worldwide (Boer, 1987). Because drills have reproduced poorly in captivity, it has been said that the California condor may have a better chance for survival than does the drill.

The San Diego Zoo's only male drill, "Loon," came from the Philadelphia Zoo on 2/18/82. He is now about 11 years old, and with the exception of a noncontagious medical condition, is robust and in prime physical condition. The San Diego Zoo is an active participant in the Species Survival Plan (SSP) for the drill. SSP's are designed with the goal of preserving 90% of the genetic diversity of the founder population for 200 years. Ideally, the plan calls for each founder to be equal in its genetic representation, ensuring the maximum genetic diversity of the species. SSP's are accomplished through cooperative international breeding loans and carefully monitored stud books which detail breeding plans for the species.

The Problem

In late June, 1989, Loon's weight suddenly dropped dramatically Loon's appetite was voracious, but no matter how much he ate he could not maintain his normal body weight. Loon was immediately transferred to the Zoo's hospital for tests and closer observation. The Zoo's veterinarians determined that Loon had developed diabetes mellitus, which is treated with daily injections of insulin.

Because Loon was a wild, intractable animal, it seemed likely that the remainder of his life would be spent at the Zoo's hospital living within the confines of a small veterinary squeeze cage. But, after several months while the disease was being brought under control, Loon had become dangerously neurotic. He exhibited many stereotypic behaviors. Several times daily he would regurgitate and reingest his food, finger paint with his feces, masturbate, and perform a curious chest rubbing behavior that always culminated with his drawing his hand up to his nose to sniff his fingers. Loon also performed a "head bobbing " threat gesture towards anyone who approached his cage (Cox, 1987; Gorow, 1988). It was becoming apparent that the quality of Loon's existence was being reduced to an intolerable level by the very treatment which was necessary to save his life. Euthanasia was being considered as a humane, if distasteful, option.

A Solution?

The Curator of Mammals believed that Loon might have one option left. He wondered if Loon could be conditioned to accept his daily insulin injection. Similar conditioning for blood collection had been done with several species of marine mammals (Shinder, 1983; Krames, 1984; Keller, 1986), as well as with laboratory macaques (Vertein & Reinhardt, 1989). It was decided that the Zoo's animal trainers would establish an experimental behavior modification program with Loon. Our goal was to train him to accept his daily insulin injections voluntarily and, if possible, to allow us to take periodic samples of his blood for routine analysis.

The project presented several challenges. Loon was a wild animal with 3-inch long canine teeth and strength to match. The procedure he would be trained to allow required very close proximity with the trainer. Loon's recent medical history of being poked, prodded, squeezed, and tested, had left him a very dangerous animal. The reward regimen was another problem. Because he was diabetic, Loon's diet had to be strictly controlled. A behavior modification plan using operant conditioning depends very heavily on food rewards. But Loon had to receive all his food, every day, whether he chose to work for it or not. Finally, although stable, Loon was not healthy by normal standards.


Because of Loon's medical condition, our first training priority was to condition him to accept his insulin injections voluntarily This was begun in July, 1989, at the Zoo's veterinary hospital by hospital technicians. Necessary daily injections were being administered using a squeeze cage.

By simply pairing a food reward with his daily injection, we began to establish the medical procedure as a positive event. In the early stages of conditioning, it was necessary to continue to use the squeeze cage to immobilize him. However, Loon quickly learned to recognize the injection as a precursor to food. By pairing his afternoon meal with an injection, while at the same time fading the use of the squeeze cage, the need for immobilization quickly became unnecessary Within a few days, Loon learned to offer his back for the injection in anticipation of the reward. In addition to the food reward, Loon was being positively reinforced by the physical freedom made possible by his compliance. A simple technique had accomplished an immediate reduction of the stress which had been imposed on the animal by daily squeezing in the cage.

Encouraged by our preliminary success, we built a special cage for the project. The new cage was several times the size of Loon's hospital quarters and featured a built-in squeeze cage in a central corridor which divided the two halves of the enclosure space. Slide gates could be drawn across the doorways to either side of the corridor Most of his food would be given him while he was in this corridor This would help insure that he would always be willing to enter this space if a medical procedure for which he was not trained became necessary.

Loon was moved into his new cage in January, 1990. Once we were confident that his cooperation with insulin injections had transferred to the new facility, we began further husbandry training. Our priority now was to train him to allow venipuncture for blood sampling.

Loon was trained to reach into a stainless steel tube, cut to the exact length of his arm, and to grasp a steel rod positioned crosswise at the end of the tube (Figure 2). As long as the drill was grasping the rod, he could not easily grab the trainer.

Figure 2: Grasping the rod earns a reward. Photo by John Mitchell, ©Zoological Society of San Diego.

Within three days of his exposure to a formal program of operant conditioning, Loon was grasping the rod and holding this position until a bridging stimulus (a clicker) was sounded, signaling termination of the behavior and presentation of a food reward. Through an ellipse cut in the tube, I began to desensitize the drill to touch on his shaved forearm while he grasped the rod at the end of the tube. I began by reinforcing his allowing me to groom his arm and, on a separate command, his back. Baboons enjoy social contact (Desmond, et al., 1987). In addition to the social rewards baboons attach to grooming, Loon was also being rewarded with food items. As training progressed I would occasionally drag different items over the bare skin of his forearm. This procedure desensitized him to a variety of stimuli, and simultaneously provided an occasion to reward him for grasping the rod.

During the first several weeks of training, Loon was very aggressive. He would snatch the food reward and, if I were not quick enough in removing my hand, take a swipe at me. On several occasions he succeeded in tearing the surgical glove off my hand. To reduce his aggression, we rewarded him with additional treats when he took the reward gently.

About six weeks into his training, Loon's medical condition required a blood sample. He was given the command to place his arm in the tube and grasp the rod. Within moments, a veterinarian had withdrawn the blood sample. Loon continued to wait patiently for the bridging stimulus to terminate rod-holding. The blood withdrawal had apparently been of no concern to him as he focused on holding the rod.

Baboons walk on their hands and so have evolved tough protective pads with blood vessels deep under the skin. Pricking his finger for a blood sample was not effective. As a result of the need to test Loon's blood frequently, the veins in both of Loon's forearms have become heavily scarred. Loon has tolerated up to six failed attempts to draw blood from these battered vessels, without ever once pulling his arm away from the tube and rod. We responded to this new problem by training Loon to offer the vessels on the ventral side of both of his legs for venipuncture. Now venipuncture sites are rotated to help reduce damage to any single vessel site. In nearly one year of training, Loon has never failed to voluntarily accept his insulin injection or to allow the veterinarians access to blood vessels in exchange for a good back scratch and a food reward.


Although Loon was given several toys in his new enclosure, he confined his activity to eating his food and sitting. Searching for something that would interest him and occupy his time between training sessions, I spread out a flake of oat hay on the floor of his enclosure. Once he was allowed access to the hay, he immediately got down off his usual perch and began to pick through the leafy debris looking for morsels of food. This was the same foraging behavior normally exhibited in the wild and, in retrospect, represented the first step toward his return to normal drill behavior.

Early in the training program, we used this foraging activity as a "bonus" reinforcer for a particularly good session. Meal worms were a special treat food, and Loon never seemed to tire of searching for them amid the straw. At the conclusion of a session, meal worms were hidden in the oat straw litter for Loon to find and eat. We now do this on a daily basis. Providing opportunities for natural foraging encouraged Loon to fill the behavioral vacuum which had been caused by his medical confinement and isolation. In his activity-rich environment, there is little time for the aberrant behaviors which were usual just a few months earlier.


Work is being done with Loon on semen collection, for cryogenic preservation at our Center for Reproduction of Endangered Species "Frozen Zoo." Someday, his semen may be used for artificial insemination. There is no test available to determine if his diabetes will be transmitted genetically, but with a critically limited gene pool, we are obliged to use the genetic material available. Loon has also learned to station on scales for weight monitoring as well as to station in a small transport cage. Loon's husbandry conditioning is now complete. In November he was returned to his keepers' care and his female companions. The primate keepers have been trained in the operant techniques necessary to maintain Loon's cooperative behavior Because Loon has been such a remarkable student, he will continue to be evaluated; and other display/research/environ- mental enrichment strategies will be formulated and tested with him for use with other primates in the Zoo.

Agonistic Behavior Responses of Socially Experienced, Unfamiliar Adult Male Rhesus Monkeys (Macaca mulatta) to Pairing

Viktor Reinhardt
Wisconsin Regional Primate Research Center


Pairing previously single-caged rhesus monkeys is a safe and effective means of environmental enrichment (Reinhardt, 1990) in compliance with pending federal rules (USDA, 1990, paragraph 3.81). It has been shown that the establishment of clear-cut dominance-subordination relationships during a period of non-contact familiarization is a safeguard against injuries since partners do not need to fight over dominance when being introduced to each other (Reinhardt, 1988). The aggression-reducing effect of familiarity has also been described in experimental group formations of macaques (Bernstein et al., 1979; Bernstein & Gordon, 1980; Erwin, 1979).

Establishing isosexual pairs of adult macaques without giving the animals the opportunity to get to know each other thoroughly is not advisable when the high risk of serious trauma is taken into account (Erwin, 1986). Are there exceptions to this rule? If an experimental protocol stipulates that a partner of previously paired animals be single-caged (e.g., metabolic studies, activity studies), directly re-pairing the non-experimental animal with a new partner would save the time required for familiarization.

It has recently been shown that adult female rhesus monkeys who have lost their partner can be re-paired without prior familiarization with another female who is in the same situation without undue risk of injury (Reinhardt, 1989). What is a safe re-pairing method for females may not be equally safe for males. As a precaution, it has been the policy at the WRPRC not to implement the direct re-pairing method for adult males but instead to replace an adult male companion with an infant (Reinhardt, 1989). This is probably the easiest and safest way to provide continued social enrichment for such males who have lost their adult male companion (Reinhardt et al., 1987). But there are institutions that have no access to infants and for obvious reasons do not wish to pair males with a female.

The present investigation attempts to determine if direct repairing of unfamiliar, yet socially experienced, males can be achieved without undue risks using the same technique described for females The study is based on the hypothesis that previous exposure to another adult companion provides a monkey with important social experiences necessary to adequately cope with the potentially dangerous situation of being confronted with an unfamiliar adult conspecific of the same sex (Reinhardt, 1989). The study is further supported by the observation that male rhesus monkeys are not more aggressive than females (Reinhardt, 1987).


Eight 4-14 years old (average age 8.2 years) male rhesus monkeys (Macaca mulatta) were the subjects of this investigation. Canine teeth were blunted prior to this study to decrease the risk of injury. The animals had lived in 4 compatible pairs for more than 6 months. They were housed in 85x170x85-cm cages that were each provided with a PVC pipe for perching and a loose branch segment for gnawing and manipulating. Commercial dry food was distributed at 0730, supplemented with fruit at 1500. Water was available ad libitum. Room temperature was maintained at 21~C, with a relative air humidity of 50% and a 12-hour light/dark cycle.

Partners of different pairs were temporarily exchanged until all 24 possible dyads had been tested, one dyad per day. Two males were transferred at 1200 from their familiar companions into a test cage that had the same dimensions as the home cage. Partners were unrelated and had never lived together before.

Each pair was observed for 20 minutes, provided that neither partner inflicted a serious injury on the other. The animals were then left together for 24 hours. They were checked for signs of fighting (bruises, scratches, injuries) 6 times during this period, after which they were brought back to their original companions for one day or longer.

The partners of the 4 dyads tested at the end of the study were not separated. These pairs were checked for signs of incompatibility at least 3 times a day during a follow-up period of 2 months.

The monkeys were familiar with the observer and showed no noticeable reactions to his sitting in front of the cage and taking handwritten notes. All visible agonistic interactions and gestures were recorded during the 20-minute observations and their per-dyad occurrence and frequency computed. Agonistic interactions and gestures were categorized into contact aggression, non-contact aggression (no physical contact during the aggressive interaction) and spontaneous submissive gestures (submissive gestures were scored unless they were reactions to aggression). Dominance-subordination relationships were considered to be clear-cut if spontaneous fear-grinning and/or yielding occurred in a unidirectional way. Subordinate rank was assigned to the partner that showed these gestures.


During the first 20 minutes of pair formation, contact aggression occurred in 29% (7/24), non-contact aggression in 33% (8/24), and submissive behavior in 100% (24/24) of dyads. A total of 19 contact aggressions (0.8/dyad/20min), 33 non-contact aggressions (1.4/dyad/20min), and 319 submissive gestures (13.3/dyad/20min) were observed. Contact aggressions consisted of biting (7 times), pushing (6), slapping (4), and fighting (2). Non-contact aggressions consisted of threatening (15 staring, 3 intended slapping, 7 lunging), and chasing (8). Submissive gestures were fear-grinning (172 incidences) and spontaneous yielding (147).

The males established clear-cut dominance-subordination relationships in 96% (23/24) of dyads, on average within 24 seconds. They did so without resorting to any form of aggression in 83% (19/23) of cases. In 13% (3/23) of cases, the partners engaged in non-contact aggression, and in 4% (1/23) of cases they engaged in contact aggression while settling their rank relations. Once dominance-subordination relationships were established, aggressive behavior was shown exclusively by the dominant but never by the subordinate monkey. Partners in only one dyad failed to establish a clear-cut dominance-subordination relationship within 20 minutes.

There were 2 dyads in which partners engaged in fighting. In one case, an 8-year-old male attacked a 9-year-old counterpart, who after a brief fight in the 7th minute acknowledged his defeat by repeated fear-grinning. The two engaged in no further fighting during the 24-hour test period. In the other case, an 8-year-old male responded to repeated stare-threats from his 11-year-old counterpart by staring back. Soon after this, the younger one mounted and quickly bit the older one, who retaliated instantly but suffered a serious bite wound in the course of the ensuing fight in the 18th minute after pair formation. The two were separated and the laceration surgically treated Wound healing was uncomplicated and sutures were removed after 5 days Apart from this incident, no animal suffered any bleeding injury in the course of pair formations or during the following 24 hours.

Partner compatibility of the 4 final pairs was confirmed in all cases during the 2-month follow-up period. No incidence of fighting was recorded during this time.


The present data demonstrate that unfamiliar adult male rhesus monkeys may generally be paired directly with each other without undue risk provided partners have previously lived with another male companion. This is congruent with the findings made with adult females. It supports the assumption that previous exposure to another companion provides the animals with social skills necessary to adequately cope with the potential risk involved in being paired with an unfamliar conspecific of the same sex

Like females (Reinhardt, 1989), most of the males established clear-cut dominance relationships within a very short time. This was probably the guarantee that partners would get along with each other without much aggression. Once the dominance-subordination relationship was settled, there was little reason for the dominant male to further reinforce his status by means of aggression, since the other male refrained from aggression and consistently showed submissive gestures Also, like females (Reinhardt, 1989), males usually settled their initial dominance dispute without resorting to aggression, but the subordinate partner spontaneously acknowledged the other as dominant by exhibiting clear subordination signals. Visual cues were generally sufficient for the animals to quickly evaluate each other's relative status without the need to engage in vicious aggression that could be harmful not only for the subordinate but also for the dominant animal This supports the notion that dominance relations among rhesus monkeys are determined principally by visual means, probably as the result of prior social learning (Bernstein & Mason, 1963)

Two of the 24 dyads were exceptional, and partners had problems settling their rank relationship in a diplomatic fashion. In both dyads fighting was not immediate, but occurred only after repeated threatening, 7 and 18 minutes after pair formation. To minimize the risk involved in re-pairing unfamiliar yet socially experienced rhesus monkeys, it may be wise to observe the animals closely at pairing and separate any partners that do not establish definite rank relationships within 5 minutes. There is clearly a risk when partners are left together if one of them is reluctant to voluntarily submit to the other

Impact of the Recent Filovirus Episode on Nonhuman Primate Supplies

Joe R. Held
Charles River Laboratories

I can summarize my talk in one sentence. Primate supplies will be reduced in number, and increased in cost. But before I get into that I'd like to review a bit of history. It seems like a very short time ago that I was part of an NIH group charged with looking at the future of primate supplies and at ways to cope with the shortages arising from the actions of various governments.

In October 1978, the Interagency Primate Steering Committee released its National Primate Plan. The plan's opening statement says:

A severe and long-term shortage of nonhuman primates threatens the continuation of many essential health activities. This shortage includes the rhesus monkey and other primate species needed for health and other scientific purposes. The primate shortage has not been met by private enterprise. Federal action is required to deal with the problem (IPSC, 1978, p.1).

I see similarities with the situation today. Coordinated federal action will be needed to resolve the present problem. It is appropriate for this to be done because it is every bit as much in the national interest today as it was in 1978. Those of us working in the private sector are willing to cooperate to do what is possible to resolve this problem, but the solutions require government decisions and actions that are beyond our scope and authority. I would like to review briefly the chronology of events over the past several months.

In November, 1989, a veterinarian working in an importer's facility in Reston, VA, diagnosed simian hemorrhagic fever (SHF) in a group of cynomolgus monkeys imported from the Philippines in October. The veterinarian submitted specimens from these animals to the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) for confirmation of the diagnosis. The USAMRIID confirmed the diagnosis of SHF, but also found that some animals were infected with an agent that morphologically resembled Ebola virus, a member of the Filoviridae family. The Ebola virus includes both Zaire and Sudan strains and had caused serious human disease outbreaks in Africa in 1976 and 1979 Subsequently, an agent was isolated from the Reston outbreak, a distinct, previously unrecognized member of the Filoviridae. Both SHF and Ebola had previously been associated only with Africa, and it was assumed that the cynomolgus imported from the Philippines might have been infected by contact with African species during their transit to Virginia. Cynomolgus monkeys imported from the Philippines during the months of December 1989 and January 1990 were actively infected with filovirus and some of these monkeys were sick. However, no illness or seroconversions occurred among persons in contact with these animals during this period. On January 19, 1990, the CDC, in Morbidity and Mortality Weekly Report, gave an update on the situation and included "Interim Guidelines for handling nonhuman primates during transit and quarantine" (see this Newsletter, 1990, 29[2], 2-4).

Early in March 1990, a laboratory worker accidentally cut himself while carrying out a necropsy of an animal that subsequently proved to be viremic with the new Reston agent. About this time, the CDC began to consider placing an embargo on the importation of cynomolgus monkeys. On March 21, the New York State Department of Health issued an order prohibiting the importation of any cynomolgus, rhesus, or African green monkeys that have not previously been quarantined abroad for 60 days, and shown to be filovirus antibody negative. Before March 21, the John F. Kennedy Airport in New York had been the port of entry for more than 80% of nonhuman primates entering the U.S., and the New York order brought a halt to those importations. The New York order also requires an additional 60 day quarantine period after importation, and continued negative filovirus antibody serology.

On March 22, 1990, the CDC revoked the registrations of three of the four major nonhuman primate importers, bringing about an important reduction in the number of animals being imported. On March 23, CDC held a hearing on the subject at which several persons from the biomedical community testified on the impact an embargo might have on the national biomedical effort. All the speakers testified against the embargo, except one representing the ASPCA. On April 4, the CDC issued an update reporting that the new Reston agent is not Ebola, but a related agent. It also reported that four animal handlers who had been in contact with some infected primates had serologic evidence of recent infection, including the one mentioned above who cut his finger while performing a necropsy on an infected animal. Interestingly, daily monitoring of that individual following the exposure did not detect antigenemia as demonstrated by the ELISA antigen capture test, although a low level infectious viremia was detected by isolation in MA104 cells on days 8 through 11. The mode of infection was presumed to be laceration for that person, but has not been determined for the other three. None of the four had clinical disease.

On April 13, 1990, a closed meeting was held at CDC with officials from Canada and the states of New York, California, Virginia, Texas, and Florida to discuss the issue and actions that should be taken. On April 18 the CDC issued a mandatory directive requiring that a special permit be obtained in advance from the Director of CDC before importing cynomolgus, African green, or rhesus monkeys into the U.S. Applicants for special permits are required to provide detailed information on 23 different items, including shipment of animals, protective measures to be taken for workers and others who might contact them during transit, methods of disinfecting aircraft, testing procedures to be used in relation to the filoviruses, and interpretation of the results. That directive remains in effect today. On July 19 and 20, the CDC held a closed meeting of the Filovirus Review Panel, representatives from various govermnent agencies. I had the opportunity to see a copy of their final report. The panel has made a number of recommendations to the CDC which, if implemented, should bring about some needed changes in current procedures.

The 1978 Primate Plan projected an annual need of 34,000 primates, and that number has proved to be reasonably accurate. Since 1978 primate breeding in the U.S. has increased, but imports are still necessary to satisfy the total demand. The numbers of primates imported steadily increased over the past five years from about 14,000 per year in 1985 to 22,000 in 1989. Species breakdowns are difficult to obtain, but in 1988 61% were from Asia, and most likely were macaques In 1989, according to CDC, 16,000 cynomolgus were imported. Of those 16,000, approximately 3,000 were reexported to laboratories in Canada, Mexico, Europe, and Japan, leaving the U.S. needing about 13,000 imported cynomolgus per year.

In 1990 all imports of the three affected species were completely stopped from the end of March until June 21, when 100 cynomolgus were imported. The next importations took place on August 10, when 400 cynomolgus were imported, then another 100 on August 14. As of September 21, another 100 had been imported. Altogether only 700 cynomolgus had been imported from the end of March to September 21. The concensus of importers is that if the current situation continues, it is highly unlikely that more than 4,000 to 5,000 cynomolgus will be imported this year, about half during the first three months. That will be less than half the 13,000 needed. I have emphasized the cynomolgus here because it is the most numerous species used, but there is a similar problem with importation of African green and rhesus monkeys.

While the primary impact will be a reduction in numbers of animals available, a secondary impact is increased cost. To comply with the CDC guidelines there are many associated expenses, such as for filovirus testing, disposable garments that must be destroyed each time one leaves a quarantine room, and disinfection and disposal of certain items as hazardous wastes. The price for primates has already had to be increased over the pre-existing base price between $200 and $350 per animal due to increased costs for testing and implementing of new quarantine procedures. If we can get back to former import levels of approximately 15,000 to 20,000 animals per year, and if these costly procedures remain in place, we are projecting an added expense of from $4.5 to $6 million using present numbers.

The cost problem probably will be worse. The figures I've presented are based only on what has to be done in the U.S. once the animals arrive here. The exporters have been affected in ways that are causing them to increase their prices to importers. The air carriers have long been reluctant to ship nonhuman primates, and this situation has added to that problem. Most of the airlines refuse to take nonhuman primates, and those that do are increasing their prices. The average shipping cost for bringing a monkey to the U.S. may have been as low as $50 previously, but it is now trebling to $150. Again, if we use the figure of 15,000 to 20,000 animals, we are talking about an increase from the exporters of maybe $200 per animal, plus an increase in shipping of $100 per animal, or a total of $300, or another $4.5 to $6 million.

Altogether we are talking about an annual increase over prefilovirus prices of between $9 and $12 million. The end user will be paying for this. In research where primates are essential, these costs reduce the funds available for actual research by this amount Using fewer primates will mean deferring research to solve disease problems. The expansion of cynomolgus breeding colonies in the U.S. is also being delayed and made more costly.

Another economic repercussion of this episode is a loss of testing business. The U.S. and Canada are the only countries in the world that imposed special import requirements because of the Reston virus Many pharmaceutical firms with research facilities abroad are now transferring some activities from the U.S. to foreign installations.

There are other areas of impact besides these numbers and costs to the biomedical community. There is the impact felt by 12 of our workers and their families when they had to be laid off because we couldn't bring in enough primates to justify keeping them on the job It was the first large scale lay-off in the history of our company, and it was hard to do. Another human impact was felt by those workers who were found to be filovirus antibody titer positive. Though they were not sick, they were concerned--some were even scared. There was also a problem for many of these positive people in their domestic situations, since some had been counseled not to have sexual relations. Relief came later when the criteria for judging an individual to be positive was increased to a higher titer.

There probably also will be some positive effects. We are rapidly learning more about filoviruses, and obviously there is a need for much more accurate information regarding this group of potentially important agents. There were probably some things about primate import and quarantine that needed to be improved, and these may now be corrected. Whether what has happened is positive or negative depends on the eye of the beholder. At a recent meeting an animal protectionist said to me, "Ebola and I make a good pair. Ebola in a very short period has been able to accomplish much more than I could by trying for many years! "

It is easy to understand how the authorities involved took the actions they did. The only previously recognized filoviruses, Marburg and Ebola, caused serious disease in humans, with high fatality rates, and there are no effective treatments. In fact, it was Marburg which led to the current primate quarantine regulations in 1975. I think that we can take comfort in the fact that those measures did work. Had this been as serious as the Marburg outbreak, there is every reason to believe that the disease would not have escaped into the general population. There's also a good deal of evidence now that we are dealing with a new agent that is not pathogenic for man. In addition, we are learning that both man and animals can have antibodies to the filoviruses without being ill, and without being a hazard for other individuals.

Now it would be in the national interest to reevaluate the situation, and to determine exactly which measures make sense, and which don't. It seems that the pre-filovirus episode quarantine procedures that were in place were probably sufficient, but if they were not they should be changed in a more logical fashion, based on better scientific evidence. It would also be beneficial if a way could be found to resolve disparity that currently exists between federal requirements and those of New York state and California. This lack of synchrony makes procedures more difficult for those concerned with supplying these species to researchers.

Recently I have attended sessions dealing with this subject at various meetings. The presentations reflect that a great deal of effort has gone, and is continuing to go, into this matter. Much has been learned. At one meeting Peter Jahrling of USAMRIID said, referring to the Reston agent: 1) it is infectious for man and therefore does pose a potential health hazard; 2) the quarantine regulations which were in place worked to contain it; 3) with early identification of the agent in a quarantine facility the disease can be adequately handled.

Putting together everything I have learned in those presentations, as well as from a number of authorities in personal communications, and from reading whatever is available on the subject, I conclude that we now have ample information to enable a panel of experts to come up with a rational approach for dealing with this matter. Coupling that information with the knowledge and experience gained through years of importing hundreds of thousands of monkeys, under pre-existing CDC regulations and with complete success in protecting the general public, I have come to the following conclusions:

I hope that some degree of normalcy can return soon because I remain firmly convinced of the importance of these species to the advancement of biomedical progress. But it will require the leadership of groups such as yours. There is confusion regarding this topic, and what is best to be done. It will require an effort at the federal level to resolve this matter. In that regard I am reminded of an excellent book, Of Acceptable Risk -- Science and the Determination of Safety, by William W. Lowrance of Harvard University. This book was published in 1976 under the aegis of the Panel on Science and the Determination of Safety of the National Academy of Sciences Committee on Science and Public Policy. It came to my attention then, while I was Director of the Division of Research Services here at NIH and Environmental Safety was one of my areas of responsibility. I would like to close by quoting from that book:

Such issues pop up with so little warning and present so many nearly balanced but opposed arguments that public decision makers often make hasty decisions that must be reversed later... No aspect of the national life escapes having crisis. ...What is special about safety crises is that they arise with little warning; their implications for well-being are taken personally and immediately by the affected public; the details of the technical assessments are often comprehensible only to a few specialists; and priorities are difficult to establish, because perceptions of the problems differ so much and because widely publicized immediate hazards distract attention from perhaps more important, but less visible, chronic ones (Lowrance, 1976, p. 105).

Controversial Project Debated

Dr. Robert Cooper, Director of the Monkey Jungle (14805 S.W. 216 St., Miami, FL 33170), recently sent us a packet of articles about the Helping Hands project, along with a thoughtful letter. The articles took quite different views of the program, which trains capuchin monkeys to help severely disabled humans to live more independently than would otherwise be possible. Articles from the Ladies' Home Journal (Salvatore, 1986) and the Smithsonian Magazine (MacFadyen, 1986) emphasize the advantages to the quadraplegics, and the affectionate relationships between them and their monkey companions. Their descriptions of the animals' training are brief and lyrical ("Whenever a monkey properly executes an assignment it receives a reward." "Negative reinforcement is administered by way of a tiny battery-powered backpack which can deliver a slight electric shock...[comparable] to the static charge sometimes generated by touching a metal doorknob." MacFayden, 130).

At the other extreme are two letters to The Simian, the monthly newsletter of the Simian Society of America, Inc. (Pascoe, 1989; McLean, 1990). Pascoe was a trainer on the Helping Hands project for 5 years, who came to the conclusion that the program "is wrong, misleading to the public, and must be stopped." She objects to: the forceful removal of infants from their mothers; placement with and subsequent removal from foster families; full-mouth tooth extraction; caging during training; training with electric shock; another separation, from trainers this time; foreign programs, imitating Helping Hands, which are less-well supervised; and the low success rate in training and placement, after a large expenditure of money and effort.

McLean's letter (1990) was less objective, and based on second-hand observations. Dr. Cooper writes: "I had difficulty believing McLean's report that 'so many capuchin mothers have had their infant babies taken from them (that) they now refuse to hold them after giving birth. They leave them on the ground and just walk away.' When asked about it, Alison Pascoe (the quoted source) said that when the mothers with infants were separated from the group and pursued with a net, they sometimes ditched their babies...a very different and believable account!"

An evaluation of the project by the Department of Veterans Affairs' Rehabilitation Research and Development Evaluation Unit (1989) did not address any of the questions of how the monkeys were treated, but concluded "that monkey helpers are useful, effective and acceptable." It stated that monkey helpers offer some freedom for caretakers, and more independence to the disabled.

A three-page flier from Helping Hands, titled "Animal Health Concerns," addresses the questions of tooth extraction, training by shock, neutering of some animals, stress in the companion animal's daily life, and health risks to the humans living with the animal.

Dr. Cooper writes: "I have been very much against the Helping Hands project for some years...based solely upon the extremes which must be taken to train these capuchins (and protect humans from attack). However, even Alison Pascoe says that the concept looks great if only successfully placed animals are considered. And I have found my contacts (all recent) with Mary J. Willard [founder and director of Helping Hands] to be very illuminating. She says that there is a grain of truth in virtually everything her critics charge, but that being deprived of the context and accompanying data leaves a very incomplete perspective. Her answers to all of my questions were extremely candid and without defensiveness. As a partial result, I now realize that this is a complex, rather than a black vs white, issue (at least for me).

Both M. J. Willard and Alison Pascoe indicated to Dr. Cooper that they would be willing to participate in a panel discussion with primatologists knowledgeable about Cebus at an ASP or similar academic meeting.

The American Veterinary Medical Association (AVMA, 1990) House of Delegates has considered a recommendation from the AVMA Animal Welfare Committee (AWC) that the AVMA oppose the concept and practice of utilizing nonhuman primates as assistive animals, but referred the recommendation back to the AWC and to the Committee on the Human-Animal Bond. There is no official AVMA position on this matter at this time The proposal by the AWC had stated: "That the AVMA is opposed at this time to the concept and practice of utilizing nonhuman primates as assistive animals, based upon serious animal stewardship and human safety concerns, including: 1) zoonotic disease and injury to humans; 2) use of aversion training techniques; 3) imposition of asocial and aberrant social behavior on naturally social species; 4) use of nondomestic species rather than a domestic one; and 5) physical mutilation of the animal (extraction of all teeth)." -- Few issues are as black or white as most activists would have us believe. -- The Editors

An Educated Baboon

I wish to report on a program that ran at the Weizmann Institute of Science (W.I.S.) for 4 years, involving a female baboon, now 7 years old. This animal served as the only live, interactive exhibit at the Garden of Science, which is part of the Youth Activities Section of the Feinberg Graduate School, W.I.S. Since my retirement from the W.I.S., she has been performing in identical fashion at the children's educational zoo at the Tsova Kibbutz near Jerusalem. The purpose of this exhibit is to demonstrate animal learning. "Malie" does this in three different ways: 1) "Reading" Hebrew words; 2) "Reading" English words; and 3) "Solving" problems in arithmetic. In all these demonstrations the visitor at the exhibit competes with "Malie" via a PC, which serves two parallel monitors. Language or arithmetic problems are presented by a scrambler. Whoever reacts first and correctly to a presented problem scores a point. Twelve problems are presented in each round. "Malie" has a vocabulary of 74 two-letter Hebrew words, 149 three-letter English words, and recognizes 37 multiplication and division problems. She will press a lever if a pair of letters is a valid word, or if the result of a problem is given correctly. For example, she will press the lever if she sees

414 / 23 = 18
but not
414 / 23 = 15

It may not surprise you that it is "Malie" who usually wins in 9 out of 10 rounds. Naturally, this monkey exhibit is very popular Hundreds of children and adults have tried their luck or skill.

Details of part of this program were presented in January 1988 at the IXth ICLAS International Symposium on Laboratory Animal Science, Bangkok, and published in its proceedings in 1990.

Research Report: Effect of Lead on Ovarian Disfunction

Researchers at the Wisconsin RPRC and the Harlow Primate Laboratory in Madison have shown that chronic exposure to low levels of lead appears to impair fertility by interfering with ovarian function. It suppresses secretion of progesterone, an ovarian hormone that is necessary for successful pregnancy and is particularly crucial for implantation of the embryo in the uterus. The ovarian dysfunction, which was revealed in a study of rhesus monkeys that received lead in drinking water, occurs even at relatively low levels of exposure that do not produce any overt signs of lead toxicity. Although the toxic effects of high levels of lead on the reproductive systems of humans and animals--including menstrual abnormalities, miscarriage, premature birth, and chromosomal anomalies in offspring--have long been recognized, the element's specific effect on ovarian hormones had been studied only in mice and had never been completely clarified.

In an earlier study, Dr. Nellie K. Laughlin of this group had noted that lead exposure resulted in menstrual irregularities. "In this study we wanted to determine if we could relate those defects to luteal function per se, as opposed to another part of the menstrual cycle," said Dr. Donald J. Dierschke. The luteal phase of the menstrual cycle follows ovulation, during which an egg is released from an ovarian follicle. The remaining follicular components change into the corpus luteum, which secretes progesterone.

Ten treated rhesus monkeys received lead acetate in drinking water 5 days a week for 7 months. The amount of lead was adjusted each week to the highest level that would not produce clinical symptoms or alterations of the central nervous system. The treated animals showed no signs of lead toxicity such as weight loss or reduced red blood cell volume, and there were no significant differences between experimental and seven control monkeys in general health. However, significant differences were seen in 3 measures of progesterone secretion. In the treated animals total circulating levels of the hormone during the study period were only 60% of those in control animals; and peak levels were reduced. Only one experimental animal showed a pattern of regular ovulatory cycles comparable to those of the control group, and this animal's progesterone levels were still lower than those of the controls.

The effect appears to be dose-related, because progesterone levels declined with increasing lead intake and increasing blood lead levels.

The investigators, who included Drs. Patricia Franks and Robert Bowman, were unable to determine the precise mechanism of action by which lead alters luteal function. Further studies will include evaluation of pituitary function, since lead may act directly upon the ovary, or it may affect the hypothalmus or the pituitary. They are also interested in further investigations of the cellular and molecular effects of lead. "Essentially nothing is known about the effects of lead at the cellular level and especially at the molecular level Our feeling is that there is a lot more to be learned there," says Dr Dierschke. -- From a report by Mary Ann Moon in the Research Resources Reporter, 1990, 14[12], 8-10

Book Review

Know Your Monkeys: A Guide to the Primates of Kenya. R. M. Eley Nairobi: Institute of Primate Research, 1989. 63 pp. [Price: $10.00 by air mail and $5.00 by sea mail. Available from: Institute of Primate Research, National Museums of Kenya, P.O. Box 24481, Karen, Nairobi, Kenya]

Beginning with a brief introduction to taxonomy and to the characteristics of the order Primates, this book continues with descriptions of each family, and under each family, the species represented in Kenya, with their physical characteristics, habitats, foods, reproduction, and behavior described in detail. A distribution map for each species helps one locate its range relative to Kenya's parks.

Unfortunately, the poor quality of the photographs (in composition and reproduction) and the separation of the color plates from the text make this book difficult to use as a field guide. I recommend taking it to a zoo and learning to identify the monkeys there before taking it on safari. Despite this drawback, this book is well-written and informative, and will help the non-specialist visitor get the most out of his encounters with primates in Kenya. -- Elva Mathiesen

News Briefs

AAALAC Celebrates 25th Year

The American Association for Accreditation of Laboratory Animal Care celebrated its 25th anniversary with a commemorative dinner in Milwaukee, October 16, 1990. AAALAC strives to promote high standards of animal care and use, improve laboratory animal welfare, and enhance biomedical research through the accreditation process. Currently, more than 530 units, including academic, commercial, government, and nonprofit organizations, are accredited. Attainment of accreditation demonstrates an institution's animal care and use program commitment to a standard of excellence beyond the minimum required by law. At the dinner, Howard University College of Medicine and University of Louisville School of Medicine were honored for maintaining accreditation for 25 years.

Supreme Court to Consider "Silver Spring" Case

The United States Supreme Court has accepted one part of an appeal filed in International Primate Protection League (IPPL), et al. v Administrators of the Tulane Educational Fund and the National Institutes of Health, an action by People for the Ethical Treatment of Animals and other animal rights groups seeking to block any euthanasia of the Silver Spring monkeys and to gain custody of the animals. The sole issue to be decided by the Supreme Court is whether the lawsuit, originally filed in a Louisiana court, was properly removed to federal court. IPPL contends there is disagreement among federal circuit courts about the applicability of this removal authority to federal agencies as well as to federal officers. No other aspect of the activists' appeal will be reviewed; the court has precluded any reopening of the standing question. In April, 1987, the Supreme Court declined to hear an activist appeal and let stand the lower court's decision that appellants lacked standing to bring suit for custody of the Silver Spring monkeys.

The Supreme Court is scheduled to hear the case in March 1991, with a decision expected late that year. -- From the NABR Update, 1990, 11[32]. See also this Newsletter, 1986, 25[3], 8; 1987, 26[1], 5; 1987, 26[2], 12; 1987, 26[4], 8; 1989, 28[2], 16-17; and 1990, 29[4], 16.

. . Cortisol response of 10 single-caged monkeys bled in a restraint apparatus was compared with that of 10 paired and 5 single-caged monkeys bled in the homecage. Cortisol concentrations did not differ significantly at first venipuncture, but did so at second, 15 minutes later.

*Inanimate environmental enrichment for group-housed rhesus macaque infants. Champoux, M., DiGregorio, G., Schneider, M. L., & Suomi, S J. (NIH Animal Center, P.O. Box 289, Poolesville, MD 20837). American Journal of Primatology, 1990, 22, 61-67.
. . Four animals raised in a peer group with apparatuses designed to promote motor activity and to provide response-contingent feedback were compared to control animals.

Journal of Virology, 1990, 64, 2290-2297.
. . It appears that a strong, immediate immune response to SIV can delay the onset of clinical SAIDS. It is also possible that mucosal inoculation causes an initial localized infection of sufficient duration to provide systemic immunity.

*The use of the polymerase chain reaction for the detection of simian immunodeficiency virus in experimentally infected macaques. Kitchin, P. A., Almond, N., Szotyori, Z., Fromholc, C. E., McAlpine, L., Silvera, P., Stott, E.

EN6 3QG, UK) Journal of Virological Methods, 1990, 28, 85-100.
. . A rapid, non-radioactive assay for the detection of proviral SIV in tissue-culture cells. It can also be used to detect the SIV gag gene in DNA isolated directly from experimentally infected cynomolgus macaque lymphocytes.

*Sialolithiasis in two chimpanzees. Orkin, J. L., & Braswell, L. D (Yerkes RPRC, Emory Univ., Atlanta, GA 30322). Journal of the American Veterinary Medical Association, 1990, 196, 1651-1653.
. . A sialolith, a calculus in a salivary gland or duct, was discovered in each of 2 common chimpanzees, of 50 that were radiographed for an experimental survey. Neither animal had any signs of discomfort, salivary gland enlargement, or dysphagia.

(Dept. of Virology & Immunology, Southwest Foundation for Biomedical Research, West Loop 410 at Military Dr., San Antonio, TX 78284). AIDS Research and Human Retroviruses, 1990, 6, 275-285.
. . Data suggest that simian viruses from distinct subspecies also have phenotypic and genotypic variations demonstrating viral evolution coincident with host divergence.

*Electrolyte abnormalities associated with diarrhea in rhesus monkeys: 100 cases (1986-1987). George, J. W., & Lerche, N. W. (Dept. of Medicine, School of Veterinary Medicine, Univ. of California, Davis, CA 95616). Journal of the American Veterinary Medical Association, 1990, 196, 1654-1658.

. . Histopathological examination of the eye of a laboratory technician who died as a result of herpes B infection from a wound by a rhesus monkey showed multifocal necrotizing retinitis associated with a vitritis, optic neuritis, and prominent panuveitis. Herpes-type virus was identified in the involved retina by electron microscopy. Postmortem vitreous and retinal cultures were positive for herpes B virus.


*Alouatta caraya: Population density and demography in Northern Argentina. Rumiz, D. I. (118 Newins-Ziegler Hall, Univ. of Florida, Gainesville, FL 32611). American Journal of Primatology, 1990, 21, 279-294.
. . Eleven groups were monitored regularly over 28 months, and 11 other groups were also noted in 150 ha of forest patches spread out in a 3000 ha rural area. These groups are also compared to the population on an island near the main study area. Habitat features as well as the history of each study site may account for observed demographic differences.

*Group size variability in primates. Beauchamp, G., & Cabana, G (Sub-dept. of Animal Behaviour, Madingley, Cambridge CB3 8AA, UK) Primates, 1990, 31, 171-182.
. . Analyses of effects of mean troop size, diet, territoriality, and habitat upon temporal variability of group size, using data from 36 studies of 38 species. Results are related to social organization and to the degree of feeding interference observed within and between troops.

. . 1000 hours of contact time with a focal group showed that the animals may be pre-adapted to living in distrubed-site, forest-edge communities. The evolutionary history of M. mulatta may be tied closely to the disappearance of forest and the spread of meadows and savannahs over the last million years.

*Weed macaques: The evolutionary implications of macaque feeding ecology. Richard, A. F., Goldstein, S. J., & Dewar, R. E. (Address same as above). International Journal of Primatology, 1989, 10, 569-594.
. . Patterns of feeding ecology among living macaques conform poorly with recognized phyletic distinctions within the genus. A division between "weed" and "non-weed" species, based on differing abilities to tolerate and even prosper in close association with human settlements, cross-cuts phyletic groupings.

*Feeding ecology of the proboscis monkey (Nasalis larvatus). Yeager, C. P. (Psychology Dept., Univ. of Tennessee, Knoxville, TN 37996-0900). International Journal of Primatology, 1989, 10, 497-530.
. . Proboscis monkeys are folivore/frugivores, specializing in seed consumption, with preferences for a few dominant tree species. During times of low food abundance and/or availability proboscis monkeys switched dietary strategies and increased dietary diversity.


*Genetic relationships among three squirrel monkey types: Implications for taxonomy, biomedical research, and captive breeding. Vande-Berg, J. L., Williams-Blangero, S., Moore, C. M., Cheng, M.-L., & Abee, C. R. (Dept. of Genetics, Southwest Foundation for Biomedical Research, P.O. Box 28147, San Antonio, TX 78228-0147). American Journal of Primatology, 1990, 22, 101-111.
. . Fourteen electrophoretically variable and 12 monomorphic erythrocytic and serum proteins were used to determine the genetic relationships among Bolivian, Peruvian, and Guyanese squirrel monkeys. The use of this panel of biochemical genetic markers, combined with karyotypic analysis, can ensure a high degree of certainty that animals selected for experimental protocols are uniform with respect to unique physiological characteristics of each species and subspecies. They also can ensure that animals selected to be members of breeding colonies are of a single species/subspecies type and reproductively compatible.

*Gonadal dysgenesis with X-monosomy in a cynomolgus monkey (Macaca fascicularis). Reyes, F. I., Osborn, R. G., Fuller, G. B., Hobson, W. C., Greenberg, C. R., Ray, M., Thliveris, J. A., & Faiman, C. (C Faiman, GG449, Health Sciences Centre, 700 William Ave., Winnipeg, Manitoba R3E 0Z3, Canada). American Journal of Primatology, 1990, 22, 51-59.
. . A 3-year old female cynomolgus monkey was found to have inappropriately high circulating immunoassayable follicle-stimulating hormone and luteinizing hormone levels, compatible with primary gonadal failure. She also showed features of Turner syndrome: small body size, sexual underdevelopment, gonadal streaks with absent follicles, and a chromosomal constitution of 41,X. Considering the fetal and live birth prevalences in humans of aneuploidy in general and X-monosomy in particular, the authors predict that this chromosomal aberration underlies a high number of pregnancy failures in nonhuman primates.

*DNA "fingerprints" and paternity ascertainment in chimpanzees (Pan troglodytes). Ely, J., & Ferrell, R. E. (Dept. of Human Genetics, Crabtree Hall, University of Pittsburgh, Pittsburgh, PA 15261]. Zoo Biology, 1990, 9, 91-98.
. . Analysis of 21 cases shows that DNA probes that detect hypervariable sequences in the genomic DNA is a powerful technique for both unique assignment of biological fathers in multi-male situations and the simultaneous exclusion of all other potential fathers.

Instruments & Techniques

*Intrauterine insemination with ultrasound guidance in the long-tailed macaque (Macaca fascicularis). Tarantal, A. F., VandeVoort, C. A., & Overstreet, J. W. (CPRC, Univ. of California, Davis, CA 95616). Journal of Medical Primatology, 1990, 19, 447-453.
. . Intrauterine insemination has been performed previously, but only as a surgical procedure. Ultrasound-guided techniques provide a relatively noninvasive method.

*New methodology for measuring blood pressure in awake baboons with use of behavioral training techniques. Turkkan, J. S. (Dept. of Psychiatry & Behavioral Sciences, Johns Hopkins Univ. School of Medicine, Baltimore, MD 21205). Journal of Medical Primatology, 1990, 19, 455-466. Adult male baboons were behaviorally conditioned to extend an arm outside of the home cage and accept repeated cuff inflations for manual auscultatory blood pressure measurements. Advantages over direct arterial cannulation for blood pressure measurement during extended, chronic experiments are discussed.

. . Since most orangs in captivity are housed and fed in groups which bear no resemblance to natural population units, food distribution is often inappropriate and leads to obesity in some animals, underfeeding in others. A diet and feeding program is described, along with methods of calculating energy requirements for animals of varying age and size.

*Composition of the diet of lowland gorillas at Lopé in Gabon. Williamson, E. A., Tutin, C. E. G., Rogers, M. E., & Fernandez, M. (Dept. of Psychology, Univ. of Stirling, Stirling FK9 4LA, Scotland) American Journal of Primatology, 1990, 21, 265-277.
. . Data collected over 6 years, from feeding trails and by direct observation, but mostly by fecal analysis. More foods were recorded here than elsewhere, and this is the most frugivorous population studied so far.

M. (WRPRC, 1223 Capitol Court, Madison, WI 53715-1299). Developmental Brain Research, 1990, 53, 157-167.
. . Prenatal administration of dexamethasone (DEX) and other corticosteroids has been used for prevention of neonatal respiratory distress syndrome. Injection of pregnant monkeys with DEX resulted in degenerative changes in fetuses delivered by Caesarean section 3 or 30 days later.


*Increased carbon monoxide excretion in Bolivian squirrel monkeys with fasting hyperbilirubinemia. Rodgers, P. A., Cornelius, C. E., Vreman, H. J., & Tarkington, B. K. (C. E. Cornelius, CPRC, Univ. of California, Davis, CA 95616). Journal of Medical Primatology, 1990, 19, 485-492.
. . Pulmonary carbon monoxide excretion rates (VeCO) were 50% greater, on average, in Bolovian squirrel monkeys, which exhibit a unique fasting hyperbilirubinemia, than in fasted control Brazilian squirrel monkeys. The increased VeCOs are consistent with concurrent increases in endogenous bilirubin production rates. Overproduction of bilirubin may be responsible for this difference.

*Relationship of serum total calcium and albumin and total protein in owl monkeys (Aotus nancymai). Weller, R. E., Buschbom, R. L., Ragan, H. A., Baer, J. F., & Malaga, C. A. (Battelle, Pacific Northwest Labs, P7-50, P.O. Box 999, Richland, WA 99352). Journal of Medical Primatology, 1990, 19, 439-446.
. . A positive linear relationship was found between total calcium and albumin, and between total calcium and total protein in the serum of 205 owl monkeys. Adjusted calcium calculations for monkeys based on albumin concentration were similar to those for man and dogs, but different from those based on total protein.

*Comparison of auditory functions in the chimpanzee and human Kojima, S. (Primate Research Inst., Kyoto Univ., Kansin, Inuyama, Aichi 484, Japan). Folia Primatologica, 1990, 55, 62-72.
. . Absolute thresholds for pure tones, loudness, frequency, and intensity difference thresholds, and the resonance of the external auditory meatus were measured in chimpanzees and compared with those in humans The effects of differences in hearing between species upon speech perception are discussed

*Long-term effects of early social isolation in Macaca mulatta: Changes in dopamine receptor function following apomorphine challenge Lewis, M. H., Gluck, J. P., Beauchamp, A. J., Keresztury, M. F., & Mailman, R. B. (Biological Sciences Research Center, CB#7250, BSRC, Univ. of North Carolina, Chapel Hill, NC 27599-7250). Brain Research, 1990, 513, 67-73.
. . Results from 8 isolated and 8 socially reared individuals support the hypothesis of long-term changes in the sensitivity of central dopamine receptors, as estimated by apomorphine challenge, induced by early social deprivation of rhesus monkeys. Cisternal CSF monoamine metabolite concentrations, examined prior to any drug challenge, were not different between groups.

*Acute hypotensive responses to peptide inhibitors of renin in conscious monkeys: An effect on blood pressure independent of plasma renin inhibition. Schaffer, L. W., Schorn, T. W., Winquist, R. J., Strouse, J. F., Payne, L., Chakravarty, P.K., de Laszlo, S. E., ten-Broeke, J., Veber, D. F., Greenlee, W. J., & Siegl, P. K. S. (P. Siegl, Dept. of Pharmacology, Merck Sharp & Dohme Research Labs, West Point, PA 19486). Journal of Hypertension, 1990, 8, 251-259.
. . Peptide renin inhibitors can elicit blood pressure reductions by a plasma renin-dependent as well as a plasma renin-independent mechanism. Therefore, studies designed to investigate the antihypertensive efficacy of renin inhibitors may overestimate the renin-dependent hypotensive activity of these peptides.

*The effects of depo-medroxyprogesterone acetate (DMPA) on copulation-related and agonistic behaviors in an island colony of stumptail macaques (Macaca arctoides). Linn, G. S., & Steklis, H. D. (Nathan Kline Inst. for Psychiatric Research, Orangeburg, NY 10962). Physiology & Behavior, 1990, 47, 403-408.
. . Repeated DMPA treatment of adult females led to decreases in males approaching those females and dominant male following them. As treatment did not affect females genital presenting, or females approaching or following males, it is concluded that DMPA primarily reduced female sexual attractiveness. The treatment was also consistently associated with increased female agonistic behavior, but did not alter dominance relationships.

*Immunological indicators for a nonhuman primate model of psychosocial stress. Iturrian, W. B., & Bunnell, B. N. (Dept. of Pharmacology, Univ. of Georgia, Athens, GA 30602). International Journal of Neuroscience, 1990, 51, 227-229.
. . Cortisol, ACTH, PRL, PBL number, viability, and mitogen responses, as well as various aggressive, submissive, and affiliative social behaviors, were monitored during social stress, produced by adding a stranger into a group and other manipulations. Results suggest that experimental paradigm for psychoneuroimmunology should use multivariate input (stress and host variables) while analyzing multiple immunological outcomes.

*Dominance and immunity in chimpanzees (Pan troglodytes). Masataka, N., Ishida, T., Suzuki, J., Matsumura, S., Udono, S., & Sasaoka, S (Dept. of Anthropology, Fac. of Science, Univ. of Tokyo, Hongo, Bunkyo, Tokyo 113, Japan). Ethology, 1990, 85, 147-155.

. . A summary of the present status of techniques. Although pregnancies have been initiated in the chimpanzee and gorilla using thawed frozen semen, there has not yet been a birth from in vitro fertilization.

*Changes in electrical impedance of the vaginal medium during the menstrual cycle of female rhesus monkeys (Macaca mulatta). Fischer, L., Germain, G., Florence, G., & Milhaud, C. (Ministere de la Defence, CERMA, 26, Boul. Victor, 75996 Paris, Armees, France). Journal of Medical Primatology, 1990, 19, 573-582.
. . Changes in electrical impedance of the vaginal medium during the menstrual cycle were recorded using an electrical probe, and were correlated with estradiol-17beta and progesterone plasma concentrations Results support the used of these measurements as a help for diagnosis of the periovulatory time in the female rhesus monkey.

*Determination of bioactive FSH in rhesus monkeys (Macaca mulatta) Matteri, R. L., Durning, M., Dierschke, D. J., & Handrow, R. R (WRPRC, Univ. of Wisconsin, 1223 Capitol Court, Madison, WI 53715-1299). American Journal of Primatology, 1990, 21, 295-305.
. . A new bioassay using rat Sertoli cells is shown to be useful in studying the reproductive biology of rhesus monkeys.

Shideler, S. E., Munro, C. J., Tell, L., Owiti, G., Laughlin, L., Chatterton, R. Jr., & Lasley, B. L. (CPRC, Univ. of California, Davis, CA 95616). American Journal of Primatology, 1990, 22, 113-122.
. . Enzyme immunoassay measurements of ovarian hormones in daily urine samples can be used to accurately monitor ovarian function and early pregnancy in rhesus monkeys.

*Familial incidence of multiple births in a colony of chimpanzees (Pan troglodytes). Geissmann, T. (Anthropological Inst., Univ. Zürich- Irchel, Winterthurerstrasse 190, CH-8057 Zürich, Switzerland). Jour- nal of Medical Primatology, 1990, 19, 467-478.
. . Analysis of pedigrees for multiple births over 63 years at the Yerkes chimpanzee colony demonstrate the recurrence of twins in relatively few family lines which can be traced back to a small number of ancestors, suggesting that twinning is a family trait. In addition, a relatively high level of inbreeding may have enhanced the incidence of multiple births.

*Twinning frequency in catarrhine primates. Geissmann, T. (Address same as above). Human Evolution, 1990, 5, 387-396.
. . Examining only samples of at least 1500 pregnancies, only four estimates (for Macaca mulatta and Papio hamadryas, and ranging from 0.19 to 0.35%) of twinning frequency are not rejected. Published birth samples for apes are relatively small, and twinning rates may not be reliable.

*Control data on pre- and neonatal survival of captive chimpanzees Meiss, L., Goosen, C., Schrama, A. G. L. A., & Schonk, J. (C. Goosen, TNO Primate Center, P.O. Box 5815, 2280 HV Rijswijk, Netherlands) Journal of Medical Primatology, 1990, 19, 479-484.
. . Analysis of breeding records over 7 years gives probabilities of pregnancy termination at various stages. These estimates provide a basis for comparison of different husbandry procedures. The data can also be used in evaluation of experimental procedures carried out on pregnant or prenatal animals.

*Infanticide and juvenilicide in Hanuman langurs (Presbytis entellus) around Jodhpur, India. Agoramoorthy, G. & Mohnot, S. M. (Red Howler Project, Apartado 39, Calabozo 2312-A, Venezuela). Human Evolution, 1988, 3, 279-296.
. . Seven of 12 cases of infant and juvenile killings support the reproductive advantage hypothesis, that infanticide is an adaptive behavior to increase male reproductive success. The other 5 victims were over 8 months old, and their deaths could not shorten the interbirth interval. By killing older infants and juveniles new males may get an advantage in resource competition for their own offspring.

*Abortions in free ranging Hanuman langurs (Presbytis entellus) -- a male induced strategy? Agoramoorthy, G., Mohnot, S. M., Sommer, V., & Srivastava, A. (Address same as above). Human Evolution, 1988, 3, 297-308.
. . During a 10-year long study, 6 eyewitnessed and 1 presumed cases of abortion occurred in 3 troops. Most of the reproductive losses seem to be related to psychical and physical stress exerted by new males on pregnant females. Abortions may, however, represent an adaptive reproductive strategy of females, who prefer to abort instead of investing in a fetus which is likely to be killed after birth.

*Placental implications for pregnancy complications in the chimpanzee (Pan troglodytes). Soma, H. (Dept. of Ob-Gyn, Tokyo Medical College Hospital, 1-7, Nishishinjuku 6, Shinjuku-ku, Tokyo 160, Japan). Zoo Biology, 1990, 9, 141-147.
. . Comparison of placentas from 28 term chimpanzee pregnancies with those from 171 small-for-dates, 306 premature, and 77 pregnancy toxemic human infants suggest that chimpanzees may suffer the same obstetric complications seen in human pregnancies.

*Urinary endocrine monitoring of the ovarian cycle and pregnancy in Goeldi's monkey (Callimico goeldii). Carroll, J. B., Abbott, D. H., George, L. M., Hindle, J. E., & Martin, R. D. (D. H. Abbott, MRC/AFRC Comparative Physiology Research Group, Inst. of Zoology, Regent's Park, London NW1 4RY, UK). Journal of Reproduction and Fertility, 1990, 89, 149-161.
. . Six captive females were monitored to provide measurements of the major estrone and estradiol-17beta metabolites excreted in the urine during the ovarian cycle and pregnancy. Ovulation was suppressed in 1 of 3 subordinate females housed in male-female-female trios.

*Natural suppression of fertility. Abbott, D. H. (Address same as above). Symposium of the Zoological Society of London, 1988, 60, 7-28.
. . A review of research on the social suppression of fertility in marmosets and naked mole rats.

*Hour of delivery in cynomolgus monkeys under indoor individually-caged conditions. Suzuki, M. T., Ono, T., Kohno, M., Ogawa, H., & Cho, F. (Corp. for Production and Research of Laboratory Primates, 1 Hachi-mandai, Tsukuba, Ibaragi, 305 Japan). Primates, 1990, 31, 251-255.
. . In artifically lighted (05:00-19:00) rooms, 90% of 152 deliveries took place during dark hours, with 72% occurring between 22:00 and 01:00.

*Copulatory behavior unaccompanied by ovulation in the Japanese monkey (Macaca fuscata). Nigi, H., Hayama, S.-I., & Torii, R. (Dept. of Wild Animal Medicine, Nippon Veterinary & Zootechnical College, Musoshino, Tokyo, 180 Japan). Primates, 1990, 31, 243-250.
. . Laparoscopic examination of females immediately after copulation indicate that copulatory behavior in the Japanese monkey is not always controlled by the development of a follicle or ovulation in the ovary

*Body size, sperm competition, and determinants of reproductive success in male savanna baboons. Bercovitch, F. B. (Caribbean Primate Research Center, Univ. of Puerto Rico Medical Sciences Campus, P.O Box 1053, Sabana Seca, PR 00749). Evolution, 1989, 43, 1507-1521.
. . Study of 6 troops of baboons showed that neither body size nor testicular volume was associated with differences in male reproductive activity. The outcome of fights over access to females could not be related to male body size, and ejaculatory patterns of males were independent of testicle size. Among savanna baboons, the probability of an ejaculation resulting in a conception is fairly low, which may account for the infrequency of injurious fights. Although testicle size influences sperm production, it does not influence either the timing of mating or the fertilizing capacity of spermatozoa. Social factors seem more important than size in male reproductive success of baboons.


In many cases, the original source of references in this section has been the Current Primate References prepared by The Primate Information Center, Regional Primate Research Center SJ-50, University of Washington, Seattle, WA 98l95. Because of this excellent source of references, the present section is devoted primarily to presentation of abstracts of articles of practical or of general interest. In most cases, abstracts are those of the authors.
