(Received 26 April 1977) It is becoming evident that rodents and rhesus monkeys are not suitable models for the study of all aspects of human reproductive endocrinology (Hobson, Coulston, Faiman, Winter & Reyes, 1976). Apes, on the other hand, closely resemble man in many aspects of their endocrinology (Graham, 1976). As part of a continuing study on progesterone metabolism among the great apes, we have found that the single most abundant urinary metabolite of progesterone is 5β-pregnane-3α,20α-diol (pregnanediol) in the adult female chimpanzee (YoungLai, Graham & Collins, 1975) and is similar to that in the immature chimpanzee (Romanoff, Grace, Sugarman & Pincus, 1963). This is in contrast to the macaques where androsterone is the major metabolite

AbstractI) Relationships between captive adult female rhesus monkeys were assessed for 6 weeks before and 20 weeks after birth in terms of proximity, approaches and leavings, grooming and agonistic interactions. 2) Before the births, the mothers-to-be spent more time with (and more time grooming with) related than with unrelated individuals. Responsibility for proximity with unrelated adult females to whom the mother was dominant lay primarily with the mother, but where the other female was subordinate it might lie with either party. Mothers-to-be tended to groom adult females dominant to themselves more than they were groomed by them, and vice versa. 3) Differences between the times that mothers-to-be spent near members of different age/sex/rank classes could not be accounted for in terms of generalizations describing preferences of the mothers for members of those classes nor relative preferences of them for her. 4) After the births, members of all age/sex/rank classes tended to be near (and to groom) mothers more when the infants were on the mothers than when they were off but near her, and to be near the mother more when the infants were off but near than when the infants were off and distant from the mother. Proximity between mother and others tended to become more independent of the position of the baby as it developed. 5) Differences between age/sex/rank classes in time spent near the mother after birth were generally similar to those found before birth. The index for the mother's role in maintaining proximity was predominantly negative. 6) All age/sex/rank categories tended to be near the mother less after the birth than before, especially when the infant was off its mother. The differences disappeared with time. Adult males tended to groom the mother less, and adult females to groom her more, than before birth. 7) Changes in proximity between mother and other from before to after birth can be understood in terms of an increase in the attraction of others to mother and a decrease in mothers' affinity for others.

SUMMARY Labelled progesterone was administered intravenously to five, adult female rhesus monkeys and urine and faeces were collected every 24 h. Excretion of radioactivity in urine occurred most rapidly in the first 24-h period and then declined exponentially. The excretion of radioactivity in faeces reached maxima during the 2nd, 3rd or 4th 24-h periods depending on the animal studied. 76–94% (mean 86%) of the radioactivity administered was recovered within 9 days, but small quantities continued to be excreted in urine up to 16 days after injection. Generally, greater amounts of radioactivity were recovered from faeces (41–57%) than from urine (26–48%). Using different hydrolytic and extraction procedures, some 50% of the radioactivity in urine was recovered in the neutral extracts. The major metabolite in urine was androsterone which accounted for 1·1–12·2% (mean 6·0%) of the progesterone administered. Pregnanediol was not an important urinary catabolite in this species. Differences in the extent to which progesterone is metabolized to C-19 compounds in macaques, baboons, great apes and man may reflect the phylogeny of a catabolic desmolase system in anthropoid primates.

AbstractForaging vocalizations given by Japanese and rhesus momkeys reared by their biological mothers differed from each other in a single parameter. Calls made by a Japanese monkey fostered by a rhesus female were dissimilar to those of conspecifics reared by their biological mothers, but similar to those of rhesus monkeys reared by their biological mothers, and the vocalizations given by rhesus monkeys fostered by Japanese monkey mothers were dissimilar to those of conspecifics reared by their biological mothers, but similar to those of Japanese monkeys reared by their biological mothers. Playback experiments revealed that both Japanese and rhesus monkeys distinguished between the calls of Japanese monkeys reared by their biological mothers and of the cross-fostered rhesus monkeys on one hand, and the vocalizations of rhesus monkeys reared by their biological mothers and of the cross-fostered Japanese monkey on the other hand. Thus, production of species-specific vocalizations was learned by each species, and it was the learned species-difference which the monkeys themselves discriminated.

A New Species

A new species of soft scale insect (Hemiptera: Coccomorpha: Coccidae), Luzulaspis kinakikir Tanaka sp. nov., collected from Carex miyabei (Cyperaceae), on Hokkaido Island, Japan, is described and illustrated based on adult female morphology. The new species, which belongs to the Scotica group of Luzulaspis, is similar to L. filizae Kaydan, 2015, but can be distinguished from it by possessing multilocular pores with fewer loculi; numerous dorsal tubular ducts, obviously wider than the ventral tubular ducts, and by lacking dorsal tubular ducts on the head apex. An updated diagnosis of Luzulaspis and two identification keys, one to the Japanese species of Luzulaspis and the other to the species of the Scotica group of Luzulaspis, are provided.

Lorenzo’S Oil

The new movie "Lorenzo's Oil" tells how the parents of a child with a rare illness overcame indifference in the medical establishment and, by themselves, invented a cure. The message is that medical science has become detached from the needs of those it serves, but that individuals can leap bureaucratic impediments to find new cures with their own faith and efforts ... According to the movie and the account of the parents, Augusto and Michaela Odone of Fairfax, Va., they refused to accept doctors' advice that there was no hope for their son, Lorenzo, after they were told in 1984 that he was suffering from a rare hereditary disease known as adenoleukodystrophy ... ... they defied the medical establishment's pessimism, read obscure medical journals and figured that a mixture of two natural oils, known as erucic and oleic acids, would correct an important symptom of the disease ... Dr. Rizzo began the first pilot study of the oil in August 1987. Six of 8 boys in the study deteriorated rapidly. The other two seemed to stabilize for a time, but one has now had a relapse and investigators have lost contact with the other. In a study by Dr. Hugo Moser of Johns Hopkins University School of Medicine, 70 children with the rapidly progressing disease used the oil from the time of their first symptoms until they lost sight and movement. The oil, Dr. Moser concluded, "did not make any difference." Dr. Moser said that so far he had seen no evidence that Lorenzo's disease could be prevented in boys who were otherwise destined to get it ...

Field observations were conducted in southern Saskatchewan in 1969 and 1971. Adult female Richardson's ground squirrels and their own young engaged predominantly in nasal and cohesive contacts while adults and young from other litters engaged predominantly in agonistic contacts. Identification sometimes occurred at a distance based on the location and behavior of the other animal.Newly emerged juveniles remained close to the home burrow and engaged mainly in non-agonistic interactions with both their mothers and other adults. Not until juveniles were 6–7 weeks old and were familiar with the area used by the mother did they correctly identify adults regardless of where the interaction occurred.

A coccidium of the genus Cryptosporidium, previously unreported in simians, was observed in two juvenile Rhesus monkeys. The organisms were restricted in one to the epithelium of the common bile, intrahepatic and pancreatic ducts and gall bladder and in the other to the epithelium of the small and large intestines. Epithelial hyperplasia and mucosal inflammation were common histologic features. Small bulbous enlargements that might be misinterpreted as cryptosporidia projected from the epithelial cells of some gall bladders of noninfected monkeys.
