endocrine profile of pregnancy in the patas monkey (erythrocebus patas).spontaneous toxemia occurs in approximately 6% of pregnancies in patas monkeys (erythrocebus patas). to assess further the relevance of this animal as a model system for toxemia of pregnancy in humans, we characterized the endocrine profile of the patas pregnancy by analyzing weekly blood samples for estrone, estradiol, estriol, progesterone, aldosterone, and pra throughout gestation. the profiles obtained bear striking resemblance to those described for human pregnancy, an unexpected finding si ...19853882395
fibrinopeptides a and b of japanese monkey (macaca fuscata) and patas monkey (erythrocebus patas): their amino acid sequences, restricted mutations, and a molecular phylogeny for macaques, guenons, and baboons.amino acid sequences of fibrinopeptides a and b from the macaque, macaca fuscata (japanese monkey) and the guenon, erythrocebus patas (patas monkey) were established. fibrinopeptides a of the monkeys had a sequence identical with those of baboons: ala-asp-thr-gly-glu-gly-asp-phe-leu-ala-glu-gly-gly-gly-val-arg. fibrinopeptides b were 9-residue, "short," peptides with the sequences asn-glu-glu-ser-leu-phe-ser-gly-arg for m. fuscata and asn-glu-glu-val-leu-phe-gly-gly-arg for e. patas. the sequenc ...19853928610
differences among isolates of simian hemorrhagic fever (shf) virus.simian hemorrhagic fever (shf) virus is a member of the togaviridae family which currently is unclassified to genus. we have studied the relatedness of four different shf virus isolates obtained from infected macaque or patas monkeys. differences were found among isolates in type and severity of disease produced in patas monkeys, cell sensitivity to infection, viral antigens, and levels of specific antibody induced in patas monkeys. based on these criteria, the four isolates have been grouped in ...19863945613
elimination of persistent simian hemorrhagic fever (shf) virus infection in patas monkeys.devastating epizootics of simian hemorrhagic fever (shf) have been iatrogenically initiated in captive colonies of macaque monkeys by strains of shf virus emanating from asymptomatic persistently infected patas monkeys. we have found that persistently infected patas monkeys can be cleared of their infection by superinfection with strains of shf virus which cause acute infections in this species. all 20 persistently infected animals subjected to this procedure have been cleared of their infection ...19863945628
naturally occurring yersinia enterocolitica septicemia in patas monkeys (erythrocebus patas).two cases of yersinia enterocolitica septicemia occurred in a breeding group of 22 adult patas monkeys (erythrocebus patas). affected animals had acute clinical signs of depression, weakness, dehydration, hypothermia, hepatomegaly and pronounced leukopenia. both animals died a few hours after treatment was initiated. gross necropsy findings included jaundice, fluid in body cavities, hepatomegaly, splenomegaly, multiple white foci within the liver and spleen, generalized lymph node enlargement an ...19854057942
passive joint mobility in patas monkeys (erythrocebus patas): rehabilitation of caged animals after release into a free-ranging environment.a previous study of passive joint mobility in patas monkeys (erythrocebus patas) showed that laboratory-caged animals had significantly greater mobility in most joints than age/sex matched free-ranging monkeys. passive joint mobility on 27 of the same animals was measured 6 months after the caged animals were released onto a 40-hectare island. the results show that within 6 months of becoming free-ranging, typical passive joint mobility is restored. thus, although caging directly affects measure ...19854061570
cocaine potentiates the disruptive effects of phencyclidine on repeated acquisition in monkeys.patas monkeys acquired a different four-response chain each session by responding sequentially on three keys in the presence of four geometric forms. the response chain was maintained by food presentation under a fixed-ratio schedule. errors produced a brief timeout but did not reset the chain. each day there were four 15-min sessions, with a 10-min intersession interval. cumulative dose-effect curves for phencyclidine were obtained by giving an im injection before each of the four sessions; suc ...19854080768
use of 99mtc-sulfur colloid to assess lymphatic dysfunction in filarial infection.investigations of lymphatic dysfunction in animals infected with filarial parasites has been hampered by a paucity of techniques to measure efficiency of lymphatic drainage. in this study a 99mtc-sulfur colloid technique was used to assess the efficiency of lymphatic drainage in patas monkeys infected with filarial nematodes. in all 15 uninfected hind limbs there was rapid and consistent appearance of labeled colloid in the primary lymph node (popliteal) and subsequently in the secondary nodes ( ...19854095602
induction of hepatitis b antibody in experimental animals by immunization with a-2 plaque virus.a sero-conversion for hepatitis b antibody has resulted from immunization of patas monkeys, guinea pigs, and rabbits with the a-2 plaque virus. this agent was isolated in tissue culture from patient sera that were positive for hepatitis b antigen. the immune response was assayed with techniques of direct and indirect counter-immunoelectrophoresis, and immune electron microscopy.19734128387

[schistosoma mansoni experimental schistosomiasis in erythrocebus patas monkeys (author's transl)].a number of erythrocebus patas monkeys have been experimentally infected only once, with schistosoma mansoni local strain. the various parasitological, biological and immunological observations show that e. patas is a very adequate host to schistosoma mansoni and that it develops an intestinal schistosomiasis parasitologically very close to human schistosomiasis. it is noted that in this case of single infection e. patas reactions are the same as the other species generally used in the experimen ...19806772918
serum prolactin concentrations in mangabey (cercocebus atys lunulatus) and patas (erythrocebus patas) monkeys in response to stress, ketamine, trh, sulpiride and homologous radioimmunoassay for human serum prolactin was validated to measure serum prolactin in 10 mangabey and 7 patas monkeys. mean basal levels of serum prolactin were almost identical in the males of both species and in immature and mature males. however, basal levels were higher in females than in males. serum prolactin was enhanced by stress, i.v. injection of trh and intramuscular injection of a potent dopamine antagonist (sulpiride). the rise in serum prolactin observed after i.m. i ...19816785431
complement components c3, c4, and bf in six nonhuman primate species.the extent of cross reactivity between antisera to human complement proteins [the third (c3) and fourth (c4) components and factor b (bf)] and these proteins in the sera of six species of nonhuman primates was examined. strong cross reactivity was found with these antisera and the specific complement proteins from rhesus monkeys, stumptailed macaques, cynomolgus macaques, patas monkeys, african green monkeys, and squirrel monkeys. although molecular differences were apparent as indicated by diff ...19826804713
a system for the continuous collection of 14co2 from patas monkeys: the metabolism of [14c]cloguanamile.1. an apparatus is described that allows co2 expired by monkeys to be trapped and measured and urine and faeces to be separated and collected. 2. when [14c]cloguanamile was administered to rats and to patas monkeys, a marked species difference was seen in the proportion of 14co2 expired. 3. suppression of the gut flora by neomycin revealed that this difference was due to enterofloral metabolism.19816805138
fluorescence of experimental atheromatous plaques with hematoporphyrin derivative.fluorescence of hematoporphyrin derivative (hpd) has been used clinically to localize malignant neoplasms because of its selective accumulation in these tissues. we tested the hypothesis that hpd may also be selectively concentrated within atheromatous plaques. 48 h after hpd injection in a variety of species, selective fluorescence of atheromatous plaques of the aorta was seen in each animal (rabbits and patas monkey) exhibiting such lesions. no fluorescence could be demonstrated in aortic segm ...19836822671
studies on the metabolism of the new anti-hypertensive agent, indoramin, in man.the absorption, metabolism and excretion of the new antihypertensive agent indoramin (baratol) have been studied in male volunteers following oral administration of the drug labelled either with 14c or with tritium. absorption of the drug proceeded at moderate rate, peak plasma radioactivity levels being seen by 3 h after dosing. metabolism was extensive as shown by very little unchanged compound appearing in urine. two major urinary metabolites accounting for some 35-40% of the renally excreted ...19836873141
