the cerebrospinal fluid: current concepts of its formation. | until recently it has been generally accepted that the choroid plexuses are the major source of the cerebrospinal fluid (csf). however, data now indicate that significant contributions to the csf are made at extrachoroidal sites. csf production studies and 24na transport studies in normal and plexectomized rhesus monkeys supportive of substantial extrachoroidal csf formation will be presented. although the exact mechanisms of csf formation remain to be defined, ultrafiltration is probably involv ... | 1976 | 174480 |
cyclic amp in developing muscle of the rhesus monkey: effect of prostaglandin e. | cyclic amp levels, measured by a competitive protein-binding assay and by a prelabeling technique with adenine-14 c, were determined on fetal, infant, and adult heart, diaphragm, and skeletal muscle of the rhesus monkey (macaca mulatta); the effect of pge on cyclic amp accumulation was also studied. the levels of cyclic amp were higher in the 3 types of muscle from 150-day fetuses (91% of term) than in adult muscles and even higher at 78-100 days fetal age, and histological evidence indicated th ... | 1976 | 174762 |
control of glycolysis in skeletal muscle from fetal rhesus monkeys. | in our studies of metabolic control mechanisms in skeletal muscle from rhesus fetus we have determined the tissue levels of the metabolic intermediates and cofactors of the glycolytic pathway and have calculated the mass-action ratios for each reaction. skeletal muscle from rhesus fetuses (macaca mulatta), 90-155 days of gestational age, and from adult rhesus monkeys was used in these experiments. the apparent equilibrium constants for hexokinase and phosphofructokinase (pfk) in these tissues we ... | 1976 | 175343 |

recovery of herpes simiae (b virus) from both primary and latent infections in rhesus monkeys. | the suspected ability of herpes simiae (b virus) to persist in a latent form has been confirmed in rhesus monkeys. the virus was recovered from primary oral lesions of 2 young monkeys and again, 6 months after disappearance of symptoms, from cultures of gasserian ganglia taken from the same individuals. b virus was identified by its effects in vivo and in vitro and in cross neutralization tests with antisera to reference b virus and herpes simplex virus. tests showed that the same virus was pres ... | 1975 | 177038 |
antigenic characterization of intermediate adenovirus 14-11 strains associated with upper respiratory illness in a military camp. | an unusual variant of adenovirus (av) 11 was isolated from throat and rectal swabs from six persons with upper respiratory illness in a spanish military camp in march 1969. the same strain was serologically related to the upper respiratory illness of seven other men among 25 sample cases studied in detail. after strain purification, the virus was grouped as an av by standard biological tests; it possessed the usual titers of group-specific hexon antigen but only low hemagglutinin titers (1:4 to ... | 1976 | 177365 |
multiple testing for the detection of b virus antibody in specially handled rhesus monkeys after capture from virgin trapping grounds. | eight groups of rhesus monkeys totaling over 1,000 animals were captured in the virgin trapping grounds of jammu and kashmir, india. individual caging and special handling technics were utilized to prevent cross-contamination during capture, holding, and subsequent shipment to quarantine facilities in the united states. immediately following the arrival of the monkeys, 5 consecutive blood samples were obtained at approximately 2-wk intervals, and the sera were rested for neutralizing antibody ag ... | 1976 | 177807 |
characterization of the plasma lipoproteins and apoproteins of the erythrocebus patas monkey. | patas monkey lipoproteins were fractionated into four distinct classes by a combination of ultracentrifugation and geon-pevikon block electrophoresis and characterized with respect to their chemical and physical properties. very low density lipoproteins (vldl) were isolated at d is less than 1.006, were triglyceride rich, and were in the size range 300-850 a. they were similar in apoprotein content to the vldl of man, dog, and swine. the patas monkey low density lipoprotein referred to as ldl-i ... | 1976 | 178359 |
comparative sensitivity of the bgm cell line for isolation of enteric viruses. | the bgm line of african green monkey kidney cells was less sensitive than primary rhesus monkey kidney cells or human fetal diploid kidney cells for isolation of certain echoviruses and adenoviruses from fecal specimens. | 1976 | 178630 |

the nonhuman primates as models for studying human atherosclerosis: studies on the chimpanzee, the baboon and the rhesus macacus. | there is no dearth of experimental techniques for producing the hyperlipoproteinemia resulting in atherosclerotic complications and for myocardial infarction in the non human primates. most of the recent experiments which have given information of great value have been studied with relatively expensive animals for a long period of time up to 6-7 years. it is evident that no animal model perfectly duplicates the human disease or satisfies all desirable requirements. the chimpanzees, representativ ... | 1976 | 179299 |
effective antiviral prophylaxis and therapy by systemic application of human interferon in immunosuppressed monkeys. | rhesus monkeys treated with antilymphocytic globulin were infected with vaccinia virus or with medical lake macaque herpesvirus. at the sites of inoculation of vaccinia virus, animals not treated with interferon developed typical pustulous reactions and then smaller secondary lesions. human leukocyte interferon (5 x 10(5) international units per day) injected intramuscularly, either from one day before to three days after infection or for seven days beginning on the first day of primary reaction ... | 1976 | 180202 |
prophylactic control of simian hemorrhagic fever in monkeys by an interferon inducer, polyriboinosinic-polyribocytidylic acid-poly-l-lysine. | a nuclease-resistant complex of polyriboinosinic-polyribocytidylic acid containing poly-l-lysine and carboxymethylcellulose was used as prophylactic treatment of simian hemorrhagic fever in rhesus monkeys. this infection has proven uniformly fatal to more than 50 monkeys. treatment 8 hr before infection and repeatedly thereafter completely prevented the development of viremia and death. untreated animals died before development of antibodies to the virus. none of the treated animals developed an ... | 1976 | 180207 |
complete regression of a guinea pig hepatocarcinoma by immunotherapy with "tumor-immune" rna or antibody to fibrin fragment e. | two novel immunotherapeutic regimens were developed for a uniformly lethal, intradermally growing transplantable ascites variant (line 10) of a diethylnitrosamine-induced hepatoma in strain 2 guinea pigs. in an apparently tumor-specific immunotherapy model, 32 guinea pigs were cured by the injection into the tumor area, five or seven days after tumor challenge, of syngeneic or xenogeneic rna extracts obtained from lymphoid tissues of line 10-immune strain 2 guinea pigs or rhesus monkeys, as part ... | 1976 | 181352 |
pathology of chronic bolivian hemorrhagic fever in the rhesus monkey. | gross and microscopic lesions of bolivian hemorrhagic fever (bhf) are described in 10 rhesus monkeys that survived from 30 to 78 days after subcutaneous inoculation with a dose of 10(3) plaque-forming units (pfu) of machupo virus, a dose which produces a severe and generally fatal disease. six of the monkeys had been given low doses of homologous immune globulin when initial signs of infection appeared. monkeys exhibited clinical signs in two phases. the initial signs of acute infection which be ... | 1976 | 181994 |
infection of wild and laboratory animals with machupo and latino viruses. | natural infection with machupo and latino viruses occurs only in the cricetine rodent calomys callosus. machupo virus induces fatal infection in suckling mice and hamsters, and in adult guinea-pigs, marmosets, and rhesus monkeys. latino virus kills only suckling hamsters; it produces chronic but non-viraemic infection in calomys rodents.machupo virus, in contrast, induces a viraemic immunotolerant infection in suckling calomys, and a split response in animals more than 9 days of age. tolerant in ... | 1975 | 182399 |
status of arenavirus vaccines and their application. | a limited but definite need exists for vaccines against lassa, junin, and machupo viruses. medical and laboratory personnel, as well as defined high-risk population groups, require protection from these highly virulent agents. to date little work has been done on inactivated vaccines for these viruses. a live attenuated junin vaccine has been tested successfully in more than 600 persons, and a high-passage machupo virus strain has protected rhesus monkeys against lethal infection produced by a h ... | 1975 | 182407 |
effect of indomethacin on cyclic amp phosphodiesterase activity in myometrium from pregnant rhesus monkeys. | our results indicate that indomethacin inhibits cyclic amp phosphodiesterase in the myometrium of the pregnant rhesus monkey under in vitro as well as in vivo conditions. kinetic data on extracts of myometrium from pregnant rhesus monkeys indicated two cyclic amp phosphodiesterase activities. the apparent km value for the high affinity enzyme averaged 3.9 mum and for the low affinity enzyme 23 mum; the vmax values averaged 0.56 and 1.4 nmoles cyclic amp hydrolized per mg protein min-1 respective ... | 1976 | 183237 |

cardiovascular and neuromuscular effects of dimethyl tubocurarine in anaesthetized cats and rhesus monkeys. | intravenous dose-response relationships for dimethyl tubocurarine showed that vagal blockade only became appreciable (50-83%) at doses 8-16 times those sufficient for full neuromuscular paralysis in anaesthetized cats (0.0625 mg/kg) and rhesus monkeys (0.125 mg/kg); heart rate was unchanged. sympathetic function was unimpaired by supramaximal paralysing doses of 0.5 and 1 mg/kg in cats, but was reduced (20-41%) by comparable neuromuscular paralysing doses of 1 and 2 mg/kg in rhesus monkeys; thes ... | 1976 | 183800 |
rhesus monkeys kidney cells persistently infected with simian virus 40: production of defective interfering virus and acquisition of the transformed phenotype. | monolayer cultures of llc-mk2 rhesus monkey kidney cells became persistently infected with simian virus 40 (sv40) when infected at a multiplicity of infection of 100 plaque-forming units/cell. a stable carrier state developed characterized by extensive viral proliferation without obvious cytopathic effect other than the slow growth of these cultures. by 11 weeks all cells produced the sv40 t antigen. in contrast, less than 5% of the cells produced v antigen. virus-free clonal isolates were obtai ... | 1976 | 184052 |
replication of murine paramyxoviruses in hamster tracheal organ culture and comparison with standard tissue culture methods. | replication of sendai virus, pneumonia virus of mice, and sv5 was investigated in tracheal organ cultures from 2- to 4-day-old and 2- and 4-week-old hamsters, and viral infectivity in tracheal explants was compared with that in tissue culture monolayers. explants from 2- to 4-day-old hamsters produced higher titers of the three paramyxoviruses, as detected by hemadsorption with guinea pig and murine erythrocytes in primary rhesus monkey kidney cells. tracheal cultures from 2- and 4-week-old hams ... | 1976 | 184110 |
stimulation of proliferation in stationary primary cultures of monkey aortic smooth muscle cells. part 2. effect of varying concentrations of hyperlipemic serum and low density lipoproteins of varying dietary fat origins. | the outgrowth of medial explants of thoracic aorta from rhesus monkeys has used to study the influence of hyperlipemic serum on cell proliferation. after 5-6 weeks of rapid growth in bme plus 10% normal serum, the cultures reach a stationary phase during which they show little mitotic activity. when it replaces 5% of the normal serum in the media, hyperlipemic serum induces another proliferative phase in the cultures, as measured by [3h1thymidine incorporation and increase in culture area. low d ... | 1976 | 184801 |
potentiation of the acth response to metyrapone by l-dopa in the monkey. | the intravenous injection of l-dopa (15 mg/kg) to monkeys (macaca mulatta) failed to alter plasma concentrations of acth and of 11-deoxy-cortisol. when cortisol synthesis was blocked with iv metyrapone, potentiation of acth secretion by l-dopa became apparent. simultaneous injection of l-dopa and metyrapone resulted in a marked increase in plasma acth from 93 +/- 18 pg/ml to 432 +/- 80 pg/ml, whereas plasma 11-deoxycortisol increased from 1.5 +/- 0.2 mug/100 ml to 14.6 +/- 1.0 mug/100 ml 90 min ... | 1976 | 185048 |

serum lipid and lipoprotein responses of six nonhuman primate species to dietary changes in cholesterol levels. | the response of serum lipids and lipoproteins to different levels of cholesterol in the diet was studied in chimpanzee (pan troglodytes), rhesus (macaca mulatta), green (cercopithecus aethiops), patas (erythrocebus patas), squirrel (saimiri sciurea) and spider (ateles sp.) monkeys. five animals of each species were fed increasing amounts of dietary cholesterol (0.05% to 1.5% w/w) for 3-week periods; between each experimental diet, the animals were fed a basal diet without cholesterol for a simil ... | 1976 | 186573 |
dynamics of adenosine-3', 5'- monophosphate transfer among mother, fetus, and amniotic fluid in the rhesus monkey. | cyclic amp exchange among the mother, amniotic fluid, and fetus was studied in normal rhesus monkeys at term pregnancy. following a pulse intravenous administration of 3h-cyclic amp into the mother, a small fraction of the dose appeared in less than 1 minute in fetal blood. it appeared in the amniotic fluid after 5 minutes and reached maximum level in 20 minutes. the accumulation of 3h-cyclic amp in the amniotic fluid in 1 hour was 0.03 per cent of the injected dose. the amount and time course o ... | 1976 | 187058 |
the effect of cholesterol feeding on primate serum lipoproteins. i. low density lipoprotein characterization from rhesus monkeys with high serum cholesterol. | 1976 | 187177 | |
effect of adrenergic blockade and dexamethasone on the aldosterone response to brain stimulation in the rhesus monkey. | the increase in aldosterone and plasma renin activity (pra) observed after stimulation of extrahypothalamic sites within the brain of the rhesus monkey was prevented by the prior administration of the beta-adrenergic blocking agent propranolol. alpha-adrenergic blockade by phentolamine had no inhibiting effect. propranolol only partially reduced the response of aldosterone to lateral hypothalamic stimulation in spite of inhibition of pra; a partial reduction in aldosterone was also obtained from ... | 1976 | 187707 |
sequential hepatic histologic and histochemical changes produced by diethylnitrosamine in the rhesus monkey. | six young adult male rhesus monkeys were given diethylnitrosamine ip for 3-5 years. liver biospies were done monthly. after 6 months, biopsy specimens showed individual hepatocytes and small foci of hepatocytes that were intensely positive for glycogen. during the second and later years, larger foci of such cells developed. in sections stained with hematoxylin and eosin, the glycogen-containing hepatocytes generally appeared unusually clear. some hepatocytes, however, had eosinophilic or basophi ... | 1976 | 187798 |
hyperreactive arterial endothelial cells: a clue for the treatment of atherosclerosis. | arterial endothelial cells, which are capable of phagocytizing carbon particles of the same size as beta- and pre-beta-lipoprotein, were found only in endothelial cells of arterial segments susceptible to atheromatous changes in susceptible animal species, and the distribution closely corresponded to the susceptibility. the distribution of such endothelial cells is dense in large arteries, in the openings to their branches, especially in downstream portions, of rabbits, hens, and cocks; however, ... | 1976 | 188368 |
comparison of the serum low density lipoprotein and of its apoprotein in the pig, rhesus monkey and baboon with that in man. | the principal form of the serum low density lipoprotein (ldl) in man, baboon, rhesus monkey and pig was isolated by preparative ultracentrifugation in the density interval 1.024-1.045 g/ml. the physicochemical characteristics of pig ldl most closely resembled those of man; thus, electrophoretic studies suggested that both baboon and rhesus ldl have a greater surface charge than that of their human counterpart, and electron-microscopic investigations showed baboon ldl (245 a) to be larger and rhe ... | 1976 | 188432 |
study of abnormal plasma low-density lipoprotein in rhesus monkeys with diet-induced hyperlipidemia. | male rhesus monkeys were divided into three groups: five were fed a regular primate chow diet and were used as controls; four received an "average" american diet; and five a special low-fat primate chow diet supplemented with 25% coconut oil and 2% cholesterol. in all of these animals, the plasma low-density lipoproteins (ldl) were isolated by ultracentrifugal flotation between densities of 1.019 and 1.050 g/ml. the ldl of the five control monkeys had variable molecular weights, with a mean valu ... | 1976 | 188443 |
influence of lysophosphatidylcholine on the metabolism of plasma lipoproteins. | both low density lipoproteins and cellular membranes are known to have a high affinity for lysophosphatidylcholine. in this study lysophosphatidylcholine influenced the retention of lipoproteins by arterial tissue in vitro and the rate of disappearance of low density lipoproteins from the blood in vivo. pieces of aorta from rabbits or rhesus monkeys were successively incubated for 90 min each in 2 or 3 solutions. after the last incubation the intima plus inner media was dissected from the remain ... | 1976 | 188451 |
plaque assay of neonatal calf diarrhea virus and the neutralizing antibody in human sera. | neonatal calf diarrhea virus (a bovine rotavirus) formed distinct plaques in monolayers of ma-104 cells, an established macacus rhesus monkey kidney cell line, when diethylaminoethyl dextran and trypsin were included in the overlay medium. by using this plaque assay method, titration of neutralizing antibody to neonatal calf diarrhea virus was made feasible. it was demonstrated that some human sera contained neutralizing antibody to this agent. | 1977 | 188863 |
cortisol secretion and clearance in the rhesus monkey. | cortisol secretory patterns were studied in two chair-adapted rhesus monkeys by simultaneous measurement of plasma concentration and specific activity of cortisol after an iv bolus of 14c-labeled hormone. the results indicated that fluctuating plasma cortisol concentrations are the result of episodic secretion by the adrenal cortex. specific activity changes during these spontaneous secretory bursts indicated occasional submaximal activity. in addition, cortisol secretory rates calculated during ... | 1977 | 189992 |
estrogen metabolism in nonhuman primates. i. in vitro biosynthesis of estrogen glucosiduronates in rhesus monkey liver. | estrone glucosiduronate, 17beta-estradiol-3-glucosiduronate, 17beta-estradiol-17-glucosiduronate and estriol-16alpha-glucosiduronate have been biosynthesized in substantial yield by incubation of radioactive estrone, 17beta-estradiol, estriol and uridine diphosphoglucosiduronic acid with rhesus monkey liver homogenates. the metabolites were characterized by chromatography on celite and deae-sephadex, enzyme hydrolysis, derivative formation and crystallization to constant specific activity. the p ... | 1977 | 190739 |
[ultrastructural changes in the central nervous system of monkeys in poliomyelitis]. | the ultrastructure of cells of the central nervous system of rhesus monkeys in experimental poliomyelitis caused by virus of poliomyelitis type 3 was studied. it was found out that the virus of poliomyelitis was localized in nerve cells, astocytes, oligodendrocytes, the endothelium of capillaries and macrophages. this justifies the conclusion that pathological changes in the cells referred to the above result from reproduction of the virus therein. ultrastructural changes in infected cells are d ... | 1976 | 190980 |
stimulation of cholesterol esterification in rhesus monkey arterial smooth muscle cells. | the influence of homologous high density lipoprotein (hdl) and low density lipoprotein (ldl) and of whole hypercholesterolemic serum on the esterification of oleic acid and cholesterol was studied in rhesus monkey arterial smooth muscle cells. whole hypercholesterolemic serum and isolated ldl stimulated cholesterol esterification as much as 10-fold using either cholesterol-1,2-3h or oleate-1-14c as substrate. at the same concentrations of cholesterol, hdl stimulated cholesterol esterification to ... | 1977 | 191212 |
characterization of plasma low density lipoproteins on nonhuman primates fed dietary cholesterol. | ldl from animals of three nonhuman primate species, macaca mulatta, macaca fascicularis, and cercopithecus aethiops, were studied. a standard preparation of 125i-ldl was added to isolated lipoprotein mixtures just prior to separation of plasma lipoproteins by agarose gel chromatography. a relative size index, ri, was determined by dividing the elution volume of the iodinated ldl by the elution volume of the sample ldl, both volumes being determined simultaneously during chromatographic elution. ... | 1997 | 191551 |
comparative complement fixation and serum neutralization antibody titers to herpes simplex virus type 1 and herpesvirus simiae in macaca mulatta and humans. | the serological relationship of herpes simplex type 1 virus and herpesvirus simiae was studied. antibody titers to these viruses were determined in 163 macaca mulatta sera and 67 human sera by serum neutralization (sn) and complement fixation (cf) tests. both groups of sera were also tested by cf with envelope and capsid antigens of herpes simplex type 1. by sn, the majority of the monkeys and all of the humans had a higher titer to herpes simplex type 1 than to h. simiae. by cf, with crude anti ... | 1977 | 192762 |
spontaneous malignant histiocytoma with metastasis in a rhesus monkey [macaca mulatta]. | a malignant histiocytoma was observed on the left arm of a recently imported rhesus monkey. rapid invasion of deep tissues and tumor growth on the face prompted euthanasia. necropsy revealed additional neoplastic foci in the lungs, diaphragm, intercostal muscles, pericardium and liver. microscopically the predominant cell type was histiocytic; some cells had a distinct epithelioid appearance and other were spindle-shaped. | 1977 | 194039 |
effects of cholesterol feeding on primate serum lipoproteins. ii. low density lipoprotein characterization from rhesus monkeys with a moderate rise in serum cholesterol. | 1977 | 194586 | |
dengue viruses and mononuclear phagocytes. ii. identity of blood and tissue leukocytes supporting in vitro infection. | studies were made on the identity of human and monkey mononuclear leukocytes permissive to antibody-enhanced dengue 2 virus (d2v) infection. in cultures of peripheral blood leukocytes (pbl) inoculated immediately after separation, it was concluded that only mononuclear phagocytes support dengue infection. this is based upon observations that d2v-permissive cells were resistant to 1,200 rads, were both plastic adherent and nonadherent, were removed when passed through nylon wool columns in 10 per ... | 1977 | 195000 |
comparison of primary rhesus and cynomolgus monkey kidney cell cultures for viral isolation from clinical specimens. | rhesus monkey kidney and cynomolgus monkey kidney cell cultures were compared for viral isolation by using clinical specimens that yielded 203 viral isolates. cynomolgus and rhesus monkey kidney cells were comparable for the isolation of 22 adenoviruses, 12 coxsackieviruses, and one poliovirus. four of 50 echoviruses and seven of ten herpesviruses were detected only in cynomolgus monkey kidney cells. influenza virus was isolated in 84 instances, of which eight were detected only in rhesus and fo ... | 1977 | 195459 |
in vitro regulation of cholesterol metabolism by low density lipoproteins in skin fibroblasts from hypo-and hyperresponding squirrel monkeys. | when squirrel monkeys (saimiri sciureus) are fed diets containing cholesterol, some individuals (hyperresponders) become hypercholesterolemic, while others (hyporesponders) are able to maintain nearly normal plasma cholesterol concentrations. skin fibroblasts were grown from three hyperresponder and threehyporesponder squirrel monkeys, previously characterized on the basis of their plasma cholesterol response to two cholesterol-containing diets and the pheno-type of their parents. the rates of c ... | 1977 | 195626 |
maintenance of viability and comparison of identification methods for influenza and other respiratory viruses of humans. | a comparison of hanks balanced salt solution, veal infusion broth (vib), and charcoal viral transport medium for maintaining viability of type a influenza virus indicated approximately equal survival of virus on all three media at -70 and 4 degrees c, whereas at 25 degrees c virus survived best in vib. vib supplemented with bovine serum albumin was used as transport medium in a community-wide surveillance of febrile respiratory disease for influenza viruses. unfrozen throat swab specimens were p ... | 1977 | 195979 |
preparation and evaluation of a noninfectious monkey pox virus vaccine. | monkey pox virus was mechanically disrupted by low temperature and high pressure into soluble and insoluble fractions. soluble fractions elicited virus-neutralizing antibodies (1:20 to 1:160) in rabbits, whereas the insoluble (in saline) fractions did not (less than 1:5). no infectious virus was detected after the disruption procedure. rhesus monkeys immunized with the soluble fraction elicited virus-neutralizing (1:1,200), complement-fixing (1:16), and hemagglutinating-inhibiting (1:80 to 1:160 ... | 1977 | 195980 |

sedimentation behavior of native and reduced apolipoprotein a-ii from human high density lipoproteins. | the solution properties of human serum apolipoprotein a-ii, both in the native and in the reduced forms, were investigated by the technique of sedimentation equilibrium in the analytical ultracentrifuge. for both proteins, the apparent weight average molecular weights determined in neutral buffer systems were found to be dependent on protein concentration and invariant with the rotor speeds used (16,000 to 44,000 rpm) indicating a reversible self-association. these results were also found to be ... | 1978 | 201282 |
effect of input multiplicity on the establishment of simian virus 40 persistent infections in rhesus monkey kidney cells. | monolayer cultures of llc-mk2 rhesus monkey kidney cells become persistently infected with simian virus 40 after infection at input multiplicities of 100, 10, or 1 plaque-forming unit per cell. after 3 weeks, all cells of the cultures infected at a multiplicity of 1 plaque-forming unit per cell produced the simian virus 40 t antigen. in contrast, 8 to 11 weeks elapsed before all the cells in the cultures infected at a multiplicity of 100 plaque-forming units per cell produced t antigen. defectiv ... | 1977 | 201570 |
nonhuman primates: laboratory animals of choice for neurophysiologic studies of sleep. | a systematic study was made of several nonhuman primates to learn more about their relative usefulness for studies of sleep. species studied included the guinea baboon (papio papio), kenya or yellow baboon (p cynocephalus), olive baboon (p anubis), sacred baboon (p hamadryas), vervet monkey (cercopithecus aethiops), rhesus monkey (macaca mulatta), bonnet monkey (m radiata), crab-eating monkey (m fascicularis), patas monkey (erythrocebus patas), chimpanzee (pan troglodytes), mongoose lemur (lemur ... | 1977 | 201798 |
interspecies radioimmunoassay for the major structural proteins of primate type-d retroviruses. | a competition radioimmunoassay has been developed in which type-d retroviruses from three primate species compete. the assay utilizes the major structural protein (36,000 daltons) of the endogenous squirrel monkey retrovirus and antisera directed against the major structural protein (27,000 daltons) of the mason-pfizer monkey virus isolated from rhesus monkeys. purified preparations of both viruses grown in heterologous cells, as well as extracts of heterologous cells infected with squirrel monk ... | 1977 | 202962 |
[sleep changes induced by chronic administration of s. 1694 (survector) (author's transl)]. | five adult macaca mulatta were studied during chronic administration (24 days) of s. 1694 (10 mg/kg, i.m.). this substance induced a significant increase of the first awakening (delaying sleep onset) and an enhancement of the duration of rem and stage 4 sleep. after withdrawal, the waking effect desappeared, but the increase in stage 4 sleep was maintained for one week and rem enhancement kept rising for 15 days. this observation of long-term action underlined the validity of drug experiments in ... | 1989 | 202987 |
