Interview with the Director of the NIH Office for Protection from Research Risks

The following are excerpts from an article in the NIH Record, 1985, 37, No. 17, describing an interview conducted by the Editor of the Record with Dr. Charles McCarthy, Director of the NIH Office for Protection from Research Risks (OPRR).

Q. [Assuming] that we are always going to have to use some animals in experiments, what can we do to eliminate unnecessary pain and unnecessary trauma in those necessary experiments that we may not be doing now?

A. Well, what can we do that we're not doing now, I'm not so sure.

But let me tell you some of the things we are doing. First, our new policy requires that before NIH will even accept an application it must be reviewed by a committee in the [potential grantee's] institution that assures us that the number of animals is not unnecessarily large or too small to get good results because, either way, animals might be wasted. Secondly, there must be reasons why a given species is used in the research. Where possible, species lower on the phylogenetic scale are preferred over species that are higher and so there is an emphasis on not using the more complex organisms in research. Finally, here at NIH the peer review system seeks justification for the use of animals.

So all kinds of protection are built into the system and if a question is raised anywhere then we put a hold on and that research cannot be funded until we have resolved the question.

Q. What agency or office within NIH is in charge of the overseeing of intramural care and use of animals within NIH's own laboratories?

A. That comes under the NIH Animal Research Committee that is chaired by Dr. Robert A. Whitney Jr. and it reports to Dr. Joseph S. Rall, the Deputy Director for Intramural Research. So they have that responsibility. Now their policy was developed and published prior to the new Public Health Service's policy but on all significant points the two policies are in agreement. So we don't have two sets of standards -- one for the intramural (inside NIH) and one for the extramural -- but there are some technical details in which they are different. Generally speaking, they agree.

Q. That brings us to the extramural system: the animals and their use in laboratories and institutions outside NIH which funds the projects. Who oversees them and how do they go about it?

A. That part is overseen by the Office for Protection from Research Risks. And our office, although located organizationally at NIH, has responsibility for all animals that are involved in research supported by any of the Public Health Service agencies. So it is Public Health Service policy that we implement, not simply an NIH policy -- though because NIH is the biggest -- it's sometimes referred to as the NIH policy.

Q. But NIH is not a regulatory agency as such, designed to impose penalties, is it?

A. That's why we do this in the name of the PHS which has delegated regulatory responsibility from the Secretary of the Dept. of Health and Human Services.

Q. So, if you find something in an NIH or PHS grant that is wrong, NIH does have a regulatory power.

A. It comes to the equivalent of that. We implement what is called "policy" and the policy for practical purposes is little different than a regulation. As far as the institutions that are affected by it, there is no difference.

Q. So, the PHS as a whole has delegated authority from the Secretary to do certain things.

A. Yes. Our policy actually constitutes conditions under which awards may be made. In other words, if an institution accepts an award it accepts the responsibility to treat the animals in a humane way consistent with our policy.

Q. And of course you could suspend a grant or withdraw it for violations involving animals.

A. Yes, we have very strong sanctions available to us. We can either suspend a portion of an award, the entire award, or in an extreme case, we can suspend all of an institution's awards involving animals. And we have recently done the latter in one case. We have done it in a major institution.

Q. But the U.S. Department of Agriculture has another kind of authority -- similar -- but with different kinds of inspections and different kinds of penalties?

A. Yes. The USDA has responsibility for implementing the Animal Welfare Act. The Animal Welfare Act pertains to most animals with the exception of rats and mice. And since somewhere in the range of 90 percent of all research animals are rats and mice, there are many institutions that are not directly supervised or inspected by the USDA.

Secondly, the Animal Welfare Act specifically excludes research activities so that our policy really affects the care of animals including rats and mice which are not covered by the USDA as well as the use made of animals in a research context which is not covered by USDA. Nevertheless, we do work closely with them.

Q. Coming back to NIH, your office -- OPRR -- is the one that decides whether an investigation should be made. On what basis do you decide that?

A. Well, whenever we receive an allegation of noncompliance with PHS policy, we initiate an inquiry. If that inquiry leads us to believe there may be serious problems then we elevate the inquiry to a full-scale investigation.

Q. If you have to go to a full-scale investigation, who actually conducts it? Do you delegate it to some inspectors or investigators?

A. Normally (OPRR) conducts it, but we borrow personnel from various institutes and we frequently contract with outside experts to assist us.

Q. So whoever does the investigating knows what to look for and how to assess it?

A. Yes, that is correct.

Q. There's been some controversy and a charge that there's been a delay in the University of Pennsylvania head injury investigation. How long did it take and was it longer than ordinary and was there justification for the length of it?

A. It's hard for me to say what is ordinary because some investigations are very brief. In fact, most others have taken as long or longer than the University of Pennsylvania. The reason for the extended investigation at the University of Pennsylvania was that the principal evidence in that case was stolen evidence. And the people in possession of that information declined to turn it over to us for nearly a year.

We received that evidence on May 23 of this year and it consisted of approximately 80 hours of videotape, which had to be carefully analyzed. So between May 23 and mid-July most of that tape was reviewed up to five times and documentation was made on every single animal and the treatment of every single animal; some 47 animals were depicted on the tape and we then completed a report based on our analysis of the entire set of tapes. We think the investigation was really completed in a rather short time once the evidence was in hand. But the evidence was stolen one year prior to its being turned over to the NIH.

Q. Assuming you find there is some violation of the rules and regulations in a given project -- and that it warrants some kind of penalty -- what are the different kinds of things you can do and on what basis do you do them?

A. Well, we try to make the punishment fit the crime. There are two categories of noncompliance: the first and the more common is that an institution's administration of its animal policy or facilities has fallen below acceptable standards. In that case, we hold the institution responsible for bringing the policies or facilities into compliance with the PHS policy.

In a few cases, the facilities and the institution may be functioning properly but the investigator has broken the rules. In which case, we try to make the sanctions pertain to a given project or to a specific investigator since it doesn't seem to be the entire institution that's out of line.

Q. So NIH has adequate, ample power to remedy malpractices when it finds them.

A. Yes, but we feel that our investigations have to be very carefully carried out because in the event that we have negative findings, the accused have the right to appeal. Those appeals are reviewed according to very rigorous administrative procedures and consequently the evidence we have to have must be conclusive. So we cannot -- simply on the basis of casual allegations -- bring about sanctions. If we can develop demonstrable evidence, then we take appropriate action. These inquiries and investigations are carried out, at least from our point of view, in a confidential manner.

Frequently, the institution or the investigator will give statements to the press so not all of them are carried out in a confidential manner. But, so far as we're concerned, they're to be treated confidentially and the results are made public only when we have completed the investigation.

Q. So if there is any statement before conclusion of the investigation it would be on the part of the individual or institution, not NIH.

A. That is correct. It should be made clear that in the implementation of our policy we rely primarily on the statement of each institution that they will be in compliance with the policy and we accept that on good faith. We're not quite so naive as to think that simply putting something on paper always means that institutions are going to be in compliance. Consequently we do have a series of site visits to randomly selected institutions.

We've carried out approximately 18 of these since 1983 in addition to investigations for cause and we are continuing to carry out random site visits. That's still a small percentage of a total number of institutions but the word is out in the community that any institution is subject to receiving a visit virtually unannounced.

When we visit a site, what we look at are administrative records going back three years, minutes of the animal care committee going back three years. We interview investigators, veterinarians, and members of the Institution's Animal Care and Use Committee. We look at the facilities, we check the records of when food was procured, when cages were procured, and check these against the arrival of animals and so on.

What our site visits concentrate on is not particular shortcomings but on the quality of the administration of the program and that's the difference from USDA. USDA looks for specific shortcomings: the cage is dirty or rusty, the cagewasher doesn't work, etc.

What we look at is, does the institution have an appropriate administrative structure to deal with the problems that inevitably are going to arise in an animal program? Do they have a good engineering staff so that if something breaks it will be immediately fixed? If the plumbing gets plugged with animal hair will it be corrected immediately? Do they have a way of obtaining a new cagewasher if the old one breaks down?

Is there central procurement so that an investigator can order animals and not have them waiting out on the loading docks in wooden crates because the cages haven't arrived yet?

Those are the kind of questions that we look at; we try to get at the root of the matter.

Q. Under new regulations with more random site visits and an intensified education program, what specific things can you think of that will make it more likely there will be improved future care and use of laboratory animals?

A. Well, I think ultimately we need to get away from a regulatory stance and stress an educational effort and to that end we held a national symposium last year. We have followed up with regional meetings around the country. We have begun this process and have scheduled 8 regional meetings in this calendar year and will continue to hold these regional meetings.

We will try to reach investigators, administrators, veterinarians and other persons who have responsibility for running a good program. And we think ultimately the way to make sure that we have good programs is to sensitize people. We feel we would prefer not to do that through disciplining them or punishing them but rather through educating them. We do not consider ourselves so much a regulatory office as an educative and sensitizing office and we think that is ultimately the way to make something happen.

Use of Nylon Balls as Behavioral Modifier for Caged Primates

David M. Renquist and Francis J. Judge
National Institutes of Health

Nonhuman primates individually caged for long-term research projects in fields such as nutrition or carcinogenesis sometimes develop behavioral aberrations including rolling in the cage, frequent masturbation, self-mutilation, etc. Primate specialists have attempted to solve the problem by changing the cage location, manipulating the diet, increasing cage size, and providing various play objects. However, these approaches are sometimes impractical and may not rectify or prevent the problem. Most of the play objects used either are, or become, hazardous to the animal, get in the way of experimental manipulations in the cage, become unsanitary, or are quickly destroyed.

Recently use of a hard nylon ball* approximately 2 1/4 in. in diameter was evaluated as a "play object" to prevent or reduce long-term housing related behavioral aberrations. The nature and size of the ball prevent it from being destroyed or thrown out of standard monkey cages housing animals less than 15 kg, e.g., Hazelton Systems and Allentown hanging cages. The animals play with the ball by rolling it in the cage. Adult females hold it as a surrogate infant. Stumptail macaques often chew the ball. The hardness of the ball prevents it from being destroyed even with the most vigorous primate use. The ball easily rolls when the cage squeeze apparatus is utilized; this eliminates any problem with experimental manipulation.

The ball is considered as part of the cage and can be sterilized (220degF) or easily sanitized with the cage through the cage washer (180degF). The inert nature of the nylon renders it nontoxic, and any chewed particles pass through the intestinal tract. The Primate Unit at present has approximately 1,000 balls in use for macaques. The balls have been in use for six months. Smaller balls are available and could be used for smaller species of primates. The only problem occurred when a ball accidently dropped into a floor drain and blocked it.

Improving the environmental conditions of laboratory animals increases the quality of research by reducing stress. Public concern about animal welfare and the humane treatment of nonhuman primates and other research animals has also focused on improving conditions for caged or restrained animals. Laboratory animal specialists therefore find a continuing need to improve environmental conditions for animals involved in research projects. We feel that the use of an effective "play object" as described is a simple and inexpensive way of providing a more enriched environment for nonhuman primates in conventional laboratory housing.

Editor's Note.--We obtained a sample Nylaball and thought that it is worth mentioning that it is quite hard and made a fairly loud noise when it was dropped in one of our metal cages. While it is doubtful that all or a large number of monkeys in a colony room would be constantly dropping these balls, if they did so it would surely make quite a racket. We have not had enough experience with them to comment on their usefulness. In reply, the author noted that "noise has not been a problem with the 800 macaques [in his] Primate Unit; however, several primates use the ball to rub against the cage bars. This is infrequent and not habitual in the animals observed."

Parasitic Arthropods of Bushbabies (Galago Senegalensis and G. Crassicaudatus) Recently Imported to the U.S.A.

L. A. Durden, D. L. Sly, & A. T. Buck
Vanderbilt University School of Medicine

Ectoparasites and other arthropod parasites of captive bushbabies are poorly documented. Kohn & Haines (1982) did not record parasitic arthropods from bushbabies in their treatment of prosimian diseases. In their native Africa the bushbabies Galago senegalensis and G. demidovii are occasionally infested by the polyplacid sucking louse, Lemurphthirus galagus, whereas the bushbabies G. senegalensis, G. demidovii and G. crassicaudatus have been recorded as hosts for the congeneric Lemurphthirus stigmosus (e.g., Bedford, 1927; Ferris, 1954; Kim & Emerson, 1970, 1973). Similarly, the mites Lemurnyssus galagoensis and Galagalges congolensis have been recorded from G. senegalensis in Africa (Fain, 1957, 1963). Larval and nymphal stages of linguatulid (pentastomid) tongue worms parasitize many vertebrates in this region with little host specificity.

Breeding colonies of bushbabies (G. senegalensis and G. crassicaudatus) maintained at Vanderbilt University Medical Center (V.U.M.C.) are typically parasite-free, so that any supplemental animals received from wild stock must be quarantined and checked for infections or infestations prior to incorporation with these colonies. Most wild-caught bushbabies generally appear to be free of parasitic arthropods on arrival at the V.U.M.C. facilities, but some interesting cases recorded there warrant documentation.

On 9 November, 1983, 10 adult female G. senegalensis recently imported from Kenya were received at the above-mentioned facilities and were examined on arrival under quarantine conditions. All animals were generally in poor physical condition and louse eggs (nits) were recorded on six of them; these were cemented to pelage underfur hairs as is fairly typical for sucking lice (Anoplura). Nit densities were heavy (c. 500 nits per animal) on two of these animals and much lighter (10-50 nits each) on the other four infested animals. No lice were recorded. Microscopic examination of samples of these nits revealed that they had hatched previously (hatched, empty, louse eggs often remain attached to their host hair until the next host pelage molt). Although there are presently no identification keys to the vast majority of louse eggs, it seems very likely that the louse genus involved was Lemurphthirus since other genera do not normally occur on bushbabies.

On 21 November, 1983, 10 adult G. crassicaudatus (five males, five females) recently imported from Tanzania were received. All appeared to be in good health on arrival. On 14 January, 1984, however, one of the adult females died. Routine autopsy revealed the presence of about 60 encysted tongue worm nymphs belonging to the genus Armillifer. The species involved cannot be ascertained since the worms were not cultured to adults but they appear to be A. armillatus. The serosal surfaces of the abdominal viscera supported most cysts but some were located inside the liver lobes, spleen, diaphragm, and one lung. Although spectacular, these nymphs did not appear to have contributed to the death of this animal. Armillifer spp. tongue worms typically utilize snakes (particularly pythons) as definitive hosts where they invade the lungs, trachea and nasal passages. Eggs are released by adult worms in these sites and become attached to the surrounding vegetation via the nasal secretions of the snake. Other vertebrates (notably mammals) may ingest these eggs during foraging activities and act as intermediate hosts (as in the present infestation). Eggs hatch into larvae in the gut of the intermediate host and then penetrate its intestinal mucosa eventually molting to nymphs prior to encystment in the viscera. Transmission to the definitive snake host occurs when the intermediate host or its infested organs are consumed by these predators (Cheng, 1974).

Editor's Note: The New NIH Animal Care Guidelines

One assessment of the new Guide for the Care and Use of Laboratory Animals (see July, 1985 issue of this Newsletter, p. 6) by a lobbyist for a medical college association was, "It isn't going to cause a lot of heartburn...The policy does expand the authority of the [institutional animal care and use] committee, but not as..." much as did earlier proposed versions. Considered over-all, one might agree with the statement in Brown University's Office of Research Administration Newsletter that, "The new edition is not radically different from the old one." However, there is no question that one aim of the new guidelines, making the committees more active, will be achieved. Their responsibility and authority is increased and the focus for many of the committees that already exist (probably many people don't realized that institutions having NIH grants have been required to have animal care committees for some time) will have to shift from issues of feeding and space allocation to how animals are used in research.

Since the new policy requires institutional animal care and use committees to review and approve all portions of research proposals involving animals, verification that this procedure has taken place, signed by an individual assigned that function by the institution, must be submitted. The verification may be submitted at the same time as grant applications or contract proposals or 60 days thereafter. If submitted later, the verification letter must state any modifications demanded by the animal care and use committee.

One substantive change from earlier versions is that animal care committees will not have the power to terminate a research grant if members are dissatisfied with the quality of animal care or treatment. A majority of committee members will have the power to suspend research, but it will be up to the president or another high-level institutional officer accountable for animal care to make a final decision. That official, however, would have to report the circumstances to the NIH Office for Protection from Research Risks. In general, the new policy encourages animal care committees to educate researchers and administrators about less painful procedures by forcing them to think about their customary techniques.

The final policy also omits categories of procedures that it originally proposed would require review by all members of the animal research committee. The categories included any procedures that were "harmful or invasive" or involved "prolonged restraining." NIH resolved complaints about the vagueness of these terms by specifying that, although any member of the committee can do a review, every member must be aware of the applications to be reviewed. He or she could then request that the entire committee review a potentially controversial procedure. An institution and its animal care committee are also free to come up with a list of procedures that could be approved by a single committee member or that would require full committee review.

The composition of the committee, as was originally proposed, must have at least five members and include a veterinarian, an animal scientist, a nonscientist, and "one individual not affiliated with the institution." Animal welfare proponents had objected that such a list still didn't require the inclusion of someone with knowledge about animal welfare or ethics. The final policy suggests, but does not mandate, that the nonscientist could be an ethicist, lawyer or member of the clergy.

Each institution can assure NIH that its animal facilities and research procedures are humane either by showing proof of accreditation by the American Association for the Accreditation of Laboratory Animal Care (AAALAC) or by providing a report of self-evaluation. Only about 200 of the 840 "research entities" that received NIH grants are currently AAALAC accredited, according to NIH. In one view, the new policy provides institutions an incentive to obtain AAALAC accreditation, which is good for three years, because the self-evaluation route will be more time-consuming and demand considerably more paperwork.

One change that has not received much attention, but which could pose a major problem for some laboratories, is that some cage size recommendations have been changed, with larger enclosures suggested for the larger nonhuman primate species. For example, the minimum space recommendations for cages for Group 3 nonhuman primates (macaques and African species), weighing 3 to 10 kg, is 4.3 cu-ft (.4 cu-m) of floor area per animal, with a cage height of not less than 30 in. (76.2 cm). For Group 4 nonhuman primates (male macaques and large African species) weighing 10 to 15 kg, the numbers are 6cu-ft (.56 cu-m) of floor area per animal and 32 in. (81.28 cm) for height. Thus, the minimum cage sizes now cover a rather wide range of animal weights. Our understanding is that this was done in order to allow inspectors leeway to base their decisions on adequacy of caging on individual laboratory situations.

News Briefs

Animal Research Bills Progressing Through Congress

Animal research legislation acceptable to the research community was approved overwhelmingly by both the House and Senate in separate action, and is sure to be included in a House-Senate conference agreement during the period following the summer recess. Identical animal research provisions, contained in the House and Senate versions of the NIH Reauthorization bills require NIH to develop guidelines on the humane care and use of research animals. The measures, introduced by Senator Orrin Hatch (R-Utah) and Rep. Henry Waxman (D-Calif.), also require institutional animal research committees composed of institutional, veterinary, and community members to review research using animals. Guidelines described in the legislation are very similar to NIH rules that will become effective Nov. 1. (See July issue.)

Throughout this year, Congress has been under growing pressure from animal rights activists to pass additional legislation strengthening the existing Animal Welfare Act. Most recently, about 65 demonstrators protesting the use of baboons in federally-funded head trauma research at the University of Pennsylvania conducted a 77-hour sit-in at NIH. Funding for the project was suspended July 18 on the strength of an NIH preliminary, investigative report. But the timing of the suspension, ordered by the Secretary of the Department of Health and Human Services at the height of the NIH protest, led many to conclude that the suspension came solely to placate the animal rights protestors. The effects on animal research legislation of the NIH demonstration and the subsequent suspension of the University of Pennsylvania grant remain unclear. If Congress is still in a mood to consider additional animal research legislation, debate would focus on amendments to the existing Animal Welfare Act. Two identical measures, H.R. 2563 introduced by Rep. George Brown (D-Calif.), and S. 1233, introduced by Senator Robert Dole (R-Kan.), require the Department of Agriculture to develop standards for the humane treatment of animals. The legislation then goes on to specify what those standards must include. One objection to the legislation on the part of most scientific organizations is that researchers would be forced to comply with guidelines from NIH and standards from the Department of Agriculture. [Based on information in the August, 1985, Research Support Network bulletin. ]

University of Pennsylvania Fined

The USDA fined the University of Pennsylvania $4,000 for violations of the Animal Welfare Act following investigations of work being done at the Head Injury Laboratory. The University is appealing the fine.

Grant Funds for City of Hope Suspended

An unannounced site visit by NIH to the City of Hope research facilities in Duarte, CA, resulted in suspension of funding in excess of $5,000,000 as a result of nonconformance with PHS animal welfare policy.

Abnormal findings in the ocular fundi of colony-born cynomolgus monkeys. Suzuki, M. T., Narita, H., Cho, F., Fukui, M., & Honjo, S. (The Corporation for Production and Research of Laboratory Primates, The National Insitute of Health, Hachimandai, Yatabe-machi, Tsukuba-gun, Ibaraki-ken, 305 Japan.) Experimental Animals, 1985, 34, 131-140.
. . . The ocular fundi of 1,151 apparently healthy colony-born cynomolgus monkeys (Macaca fascicularis) ranging in age from newborn to 19 years were examined using an ophthalmoscope. 238 abnormal findings were recorded in 219 of the 1,151 monkeys. Of these, 23 were related to the optic disc and 115 to the retinal vessels. Of the remaining 100 abnormal findings, 91 were retinal degenerations and 9 were retinal hemorrhages. The 23 optic disc abnormalities consisted of 3 cases of micropapilla, 4 of ectasia and 16 of myelination of the retinal nerve fibers. Of the 115 retinal vascular abnormalities, 87 were arterial tortuosity, one was venous tortuosity, 2 were tortuosity of both artery and vein, 2 were artery-vein crossing, 20 were copper-wire artery, one was inosculation of the artery, one was vascularization of the vein and one was persistent hyaloid artery. Of the 91 retinal degenerations, one was degeneration of the periphery of the macular and the optic disc, 8 were macular degeneration and 82 were peripheral degeneration. Nine cases of retinal hemorrhages appeared under 6 years of age.

Animal Welfare

Animal pain. Wright, E. M., Jr., Marcella, K. L., & Woodson, J. F. (Dept. of Comparative Medicine, University of Virginia, Charlottesville, VA 22908). Lab Animal, 1985, 14[4], 20-36.
. . . This article deals with definition of pain, its recognition and control. It includes a discussion of various analgesics.

Physiology and Behavior

The relationship between frugivory and insectivory in primates. Redford, K. H., Bouchardet da Fonseca, G. A., & Lacher, T. E., Jr. (Florida State Museum, Museum Road, University of Florida, Gainesville, FL 32611.) Primates, 1984, 25, 433-440.
. . . Fruit and insects are two of the major components of primate diets. Previous investigators have often assumed that the consumption of fruit by primates was unassociated with the consumption of insects. The authors contend that much of what has been termed fruit-eating by primates involves a significant and deliberate ingestion of insects. The implications of this are discussed.

Measurement of serum prolactin and the effect of ketamine anesthesia on serum prolactin levels in cynomolgus monkeys (Macaca fascicularis). Yoshida, T., Kono, M., Yokota, K., Cho, F., & Honjo, S. (Tsukuba Primate Center for Medical Science, The National Institute of Health, Hachimanda, Yatabe-machi, Tsukuba-gun Ibaragi-ken 305, Japan.) Experimental Animals, 1985, 34, 165-171. [In Japanese with an English abstract.]
. . . The effect of an anesthetic, ketamine, on serum prolactin level was examined in wild-originating female cynomolgus monkeys. Serum prolactin levels were measured by the homologous radioimmunoasay system which was developed for human prolactin. The validity was confirmed by using an extract of pituitary gland from a female cynomolgus monkey as well as serum and amniotic fluid from a pregnant monkey. Additionally, serum luteinizing hormone (LH) levels were determined by the radioreceptorassay system developed in our laboratory using Leydig cells collected from rats' testes as a receptor fraction. The experiment was repeated three times at one-month intervals, using three groups consisting of 5, 7, and 8 monkeys each. In the first experiment, the first group was injected with physiological saline and the second and third groups were intramuscularily given ketamine at a dose level of 5 mg/kg B.W. and 15 mg/kg B.W., respectively. In the second experiment, the first and second groups were given ketamine at a dose of 5 mg/kg B.W. and of 15 mg/kg B.W., respectively, and the third group served as control injected with saline. In the third experiment, the first and third groups were administered with 15 mg/kg and 5 mg/kg of ketamine and the second group was injected with saline. In short, all of the twenty monkeys received the three different treatments for two months. The serum prolactin level showed a marked increase after the administration of ketamine. However, this increase was observed only in half of the monkeys and no change was observed in the remaining half. In contrast with the prolactin level, no effect was produced on the LH level by the administration of ketamine in all the animals used. The effect of ketamine on prolactin secretion from the pituitary gland in cynomolgus monkeys varied with every individual. That is, the secretion of prolactin was significantly stimulated in some animals and was not in some others. The reason for this difference among individuals is not clear as yet. However, the present study suggests that such an individual difference may explain discrepancies among the results of previous reports.

Breeding and Rearing

Resumption of seasonal breeding patterns in male and female rhesus monkeys transferred from an indoor to an outdoor environment. Herndon, J. G., Ruiz de Elvira, M-C., Turner, J. J., & Collins, D. C. (Div. of Neurobiology, Yerkes Regional Primate Research Center, Biology of Reproduction, 1985, 32, 733-744.
. . . Seasonal aspects of social behavior and sex steriod levels were observed in two groups of rhesus monkeys from March through December. One group (3 males, 7 females) had lived outdoors for several years. The other group (6 males, 5 females), transferred outdoors in late February, had lived indoors for several years. In March-April, the long-term outdoor residents displayed the expected seasonal pattern of sexual behavior, characterized by absence of complete sequences of copulatory behavior. At this time the indoor-adapted group displayed high levels of copulatory behavior. Thereafter, frequencies of sexual behavior of the two groups were similar. Testosterone in the males was positively correlated with frequency of sexual behavior in each group. Females in the indoor-adapted group displaced menstrual cycles in March and April and 3 of 5 became pregnant at this time. The two remaining indoor-adapted females continued to display ovulatory cycles, but little sexual behavior, throughout the summer. Interestingly, two females in the outdoor-adapted group also displayed summer ovulatory cycles, without concomitant sexual activity. These data show that the disruption of seasonal breeding patterns produced by lengthy indoor housing remains briefly apparent following transfer outdoors, but is substantially overcome within a few months.

Evaluation of the subhuman primate pregnancy test kit for the detection of early pregnancy in the rhesus monkey (Macaca mulatta). Naqvi, R. H., & Lindberg. M. C. (EG & G Mason Research Institute, 57 Union St., Worcester, MA 01608.) Journal of Medical Primatology, 1985, 14, 229-233.
. . . The performance of The Subhuman Primate Pregnancy Test Kit was evaluated for routine detection of early (days 19-21) pregnancy in the rhesus monkey. Out of 123 confirmed matings, 19 resulted in pregnancy. In the pregnant animals the kit had an accuracy of 73.7%. In the nonpregnant females the accuracy was higher, 88.5%. False positives were encountered in ovariectomized females as well as adult intact males.

Three successful cases of artificial insemination in chimpanzees. Matsubayashi, K., Kumazaki, K., & Kamanaka, Y. (Primate Research Institute of Kyoto University, Kanrin, Inuyama, Aichi 484, Japan.) Experimental Animals, 1985, 34, 203-206. [In Japanese with an English abstract.]
. . . Artificial inseminations were performed on two female chimpanzees from July 1981 to April 1983 and three conceptions were obtained. Semen samples collected by rectal probe method of electroejaculation were incubated at 37deg C for about 20 minutes for liquefaction. Liquefied portion of the semen was sucked up into a polyethylene tube about 30cm in length attached to a syringe and was inseminated into the cervix of each female, the pelvic region of which was raised in prone position under anesthesia. Ovulation time was estimated by swelling of sex skin in earlier two cases and by urinary LH level in last case. Three offspring were born 234, 235, and 235 days after last insemination, respectively. All three show normal development.

The roles of early separation experience and prior familiarity in the social relations of pigtail macaques: A descriptive multivariate study. Capitanio, J. P., & Reite, M. Primates, 1984, 25, 475-484.
. . . Research has suggested that a social separation during a macaque's infancy may result in later deficiencies in maternal behavior, as well as in reduced sociability. The present study examined whether monkeys now living in an all-peer group who had experienced a maternal separation 1.5 to 3 years prior to the time of these observations, displayed persisting social deficits. Using multivariate techniques, prior separation history and several demographic variables were examined as to their role in explaining the observed variation in measures of social behaior and preference. The results indicated that, as compared to nonseparated controls, previously separated monkeys played less, displayed social preferences to fewer individuals, displayed fewer contact preferences, and showed reciprocated preferences to fewer individuals. In addition, several gender and rank-related effects were found. In terms of the identities of the preferred partners, individuals preferred animals from the same natal group. The results support the notion that an early separation experience can result in long-term social impairment, although the effects appear to be subtle.

Plasma estradiol and progesterone levels during postpartum ovulation and early pregnancy in the common marmoset Callithrix jacchus. Kholkute, S. D. (Institute for Research in Reproduction (ICMR), Jehangir Merwanji Street, Parel, Bombay 400 012, India.) Primates, 1984, 25, 538-543.
. . . By two weeks following delivery, all the animals (N = 10) had ovulated as determined by a gradual rise in plasma estradiol followed by a rise in plasma progesterone ( p > 31.8 nmol/l) levels. The mean day of ovulation was 11.3 +/- 1.5. 80% of these animals became pregnant as indicated by a continued rise in plasma progesterone levels (p > 127 nmol/l) and as confirmed by transabdominal uterine palpation. These results suggest that the day of delivery could serve as a useful parameter to monitor ovulation and pregnancy in this non-menustrating primate species.

Birth spacing in langur monkeys (Presbytis entellus). Harley, D. (Dept. of Anthropology, Mills College, Oakland, CA 94613.) International Journal of Primatology, 1985, 6, 227-242.
. . . This paper presents 10 years of reproductive data on birth interval length and 5 years of data on reproductive behavior postpartum from a captive colony of gray langur monkeys housed in Berkeley, California. Birth intervals of females following different pregnancy and nursing schedules are compared. Females whose infants survive to the age of 9 months have a median birth interval of 15.4 months. Females experiencing a pregnancy failure or the loss of a neonate had median birth intervals of 9.6 and 10.7 months, respectively. The data indicate that the loss of an infant after the age of 5 to 6 months will not accelerate a female's ability to conceive or shorten the birth interval length. The available data on birth spacing from populations of free-ranging langurs are reviewed.

Effects of social rearing conditions and partus experience on periparturitional behaviour in java-macaques (macaca fascicularis). Kemps, A., & Timmermans, P. (Dept. of Comparative and Physiological Psychology, University of Nijmegen, The Netherlands). Behaviour, 1984, 88, 200-214.
. . . This study investigated the effects of social rearing conditions and partus experience on maternal behaviour directly preceding, during, and directly following birth. There were two rearing conditions: within the birth-group which included the mother and other non-peers and in a peer group. There were two groups with respect to partus experience: primiparae, whose first partus we observed, and pluriparae, of which a later partus was studied. It appeared that the behaviour of the mothers directly before the partus was not affected by the selected variables. The mothers' behaviour was not influenced by earlier rearing either during or closely after the partus, but it was affected by partus experience. Pluriparae proved more capable than primiparae in handling child and placenta.
. . . The effects of partus experience can be explained in terms of state dependent novelty. Learning in the mother is effected via her own child.

Guidelines for specification of animals and husbandry methods when reporting the result of animal experiments. Ellery, D. A. (c/o Solco Basle Ltd., Rührbergstrasse 21, CH-4127 Birsfelden, Switzerland.) Laboratory Animals, 1985, 19, 106-108.
. . . Any report on the results of animal studies must include sufficient information on the animals used and their conditions of husbandry to enable the reader to understand how the investigation was performed. Only then can he properly interpret the findings. These guide-lines provide a catalogue of the minimum information which should be included in such reports.


The rehabilitated chimpanzees of Rubondo Island. Borner, M. (Frankfurt Zoological Society, Tanzania Wildlife Conservation Project, P.O. Box 154, Mwanza, Tanzania.) Oryx, 1985, 19, 151-154.
. . . Between 1966 and 1969, 17 chimpanzees, which had all been captured in the wild and had spent various amounts of time in European zoos, were released in Rubondo Island National Park in Lake Victoria, Tanzania. Now there is a healthy population of at least 20 chimpanzees, and it is likely that there is now a second generation of Rubondo-born animals. Although the Rubondo experiment has been a success, in general chimpanzee rehabilitation seems to have a very uncertain future, mainly because suitable habitats without a wild population are difficult to find.


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 98195. 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.

Pre-Doctoral Fellowship Available

The Primate Foundation of Arizona, in association with Arizona State University, has available predoctoral fellowships for the study of chimpanzee behavior. Two annual fellowships are offered for 12 months; non-taxable award amount is $9,000. Deadlines for application submittal are: 30 September for 12-month period beginning 1 January and 31 March for 12-month period beginning 1 July. The Foundation's general aim with the awarding of this Fellowship is to encourage all forms of scientific inquiry into the behaviors of captive chimpanzees (Pan troglodytes). The Fellowship is meant for the training and support of pre-doctoral students working in disciplines relevant to the aims and policies of the Foundation. All work is done on-site at the Foundation. The Foundation is primarily interested in studies of the reproductive and mothering behaviors of captive-born chimpanzees and studies germane to the Foundation's long-term goals of improving the quality of life and reproductive potential for all captive chimpanzees. There are approximately 50 chimpanzees in the colony; ranging in ages from 1 month to 28 years. For the most part, this number will remain stable, however, some animals do temporarily cycle in and out of the colony. Infants remain with their mothers for periods up to 18 months or longer. Send letter of inquiry to: Ms. Jo Fritz, Administrative Director, Primate Foundation of Arizona, P.O. Box 86, Tempe, AZ 85281 (Phone: 602-832-3780).
