metabolism and autoradiographic distribution of delta-8- and delta-9-tetrahydrocannabinol in some organs of the monkey callithrix jacchus.	metabolism and autoradiographic distribution of the two isomeric tetrahydrocannabinols, (2,4-14-c)-delta-8-thc and (2,4-14-c)-delta-9-thc, were studied in the marmoset callithrix jacchus. of the two cannabinoids, delta-8-thc had a slower initial rate of biotransformation to the psychopharmacologically more potent 11-hydroxylated metabolite. this may explain the minor psychopharmacological activity of the delta-8-isomer. in glandular tissues an accumulation of unchanged delta-9-thc was observed. ...	1975	806815
the embryology of the common marmoset (callithrix jacchus).	earlier studies have noted the unusual placental anatomy of marmosets and the high frequency of biovular, synchorial twinning. the maintenance of a captive colony of callithrix jacchus has enabled further studies to be made of embryonic development in this species. thirty-six embryos from seventeen pregnancies were examined in detail and assigned to horizons on the basis of streeter's classification of external form and internal structure. the specimens represented tha major part of the embryoni ...	1976	827927
an outbreak of shigellosis in laboratory marmosets and tamarins (family: callithricidae).	an outbreak of shigellosis due to shigella sonnei, is reported in laboratory maintained marmosets (callithrix jacchus) and tamarins (saguinus nigricollis). the clinical signs and pathological lesions are described and the microbiological findings discussed. control of the disease was based upon hygiene and antibiotic therapy and the consequences of this approach are described in detail.	1976	819574
autoradiographic studies on the distribution of 3h-mescaline in the brain of the marmoset, callithrix jacchus.	autoradiographs of the brain of the marmoset, callithrix jacchus, show a strong labeling of the hippocampus and the n. amygdalae 18 h after injection of 3h-mescaline. a similar characteristic autoradiographic pattern was previously found in the mouse brain, too.	1976	815928
epstein-barr virus: experimental infection of callithrix jacchus marmosets.	eight common marmoset monkeys (callithrix jacchus) were inoculated with about 10(4) transforming units of b95-8 virus; seven of the marmosets died 50-111 days post inoculation and all seven showed microscopic and/or macroscopic lesions compatible with a diagnosis of lymphoproliferative disease. low levels of anti-vca antibodies were detected in plasma from six marmosets. attempts failed to establish continuous ebv-carrying lymphoblastoid cell cultures by cultivation in vitro of circulating lymph ...	1976	181333
in vitro transforming activity of ebv. i-establishment and properties of two ebv strains (m81 and m72) produced by immortalized callithrix jacchus lymphocytes.	in vitro transformation of callithrix jacchus marmoset lymphocytes was achieved with a nasopharyngeal carcinoma (npc) derived epstein-barr virus (ebv) strain, hkly-28. two permanent and virus producing lymphoblastoid cell lines, m81 and m72, were obtained. comparison between the original hkly-28 line and both m81 and m72 lines showed that passage in the marmosets lymphocytes greatly enhanced viral production and transforming activity of the virus as observed in cottontop derived b95.8 lymphoblas ...	1976	187263
the rete ovarii and follicle formation in marmosets (callithrix jacchus and callithrix penicillata).	the rete ovarii in young marmosets shows a strong reactivity for a certain number of enzymes (ldh; nadh2-tr; nadph2-tr; g-6-pdh; 6-pgdh; alpha-gpdh; beta-ohbdh and nonspecific esterase). the granulosa cells of the cortical innermost placed follicles have the same enzymatic reactivity. the germinal epithelium results negative to the mentioned group of enzymes at this phase of the development. the rete ovarii must play an important rôle in the granulosa cells differentiation.	1976	415485
the skin of the palms and soles of the marmosets (callithrix jacchus and callithrix penicillata).	the structure and histochemistry of the palmar and plantar skin were studied in four adult male marmosets (two callithrix jacchus and two callithrix penicillata). in this skin there exist well-developed epidermal ridges, to which are attached one or two ducts of sweat glands. a thick stratum corneum can be seen in the epidermis, while a distinct stratum lucidum cannot be isolated from the other layers. the stratum granulosum is constituted by one or three layers of cells containing keratohyalin ...	1976	823786
the reproductive potential of the common cotton-eared marmoset (callithrix jacchus) in captivity.	the breeding records of a closed colony of marmosets maintained for five years are described. three generations have been born and a high incidence of multiparity has been achieved. the reproductive potential of c. jacchus is higher than that of virtually any other primate maintained in captivity.	1976	818387
histochemical studies on the adrenal glands of the marmosets (callithrix jacchus and callithrix penicillata).	the histrochemistry of the adrenal glands was studied in four adult male marmosets (two callithrix jacchus and two callithrix penicillata). it was impossible to demonstrate any reactivity to udpg-gt, adh, alanyl aminopeptidase, leucine aminopeptidase, xilitol (nad-dependent) dehydrogenase, beta-glucuronidase and aryl-sulfatase in these glands. total phosphorylase was found in scattered cells of the glomerulosa and adjacent outer fasciculata of one c. penicillata. the dehydrogenases (ldh, g-6-pdh ...	1976	8944

an ethogram of the common marmoset (calithrix jacchus jacchus): general behavioural repertoire.	the behavioural repertoire of four captive breeding pairs of callithrix jacchus jacchus is described. social communication took the form of postures, facial expressions, vocalizations and piloerection displays. detailed analyses were made of piloerection displays, adult play, copulatory, aggressive, and prey-catching behaviour. aggressive behaviour was uncommon in adult mated pairs. play between adults showed a degree of temporal of temporal organization. vocalizations were the main methods of i ...	1976	820223
the effect of dexamethasone in traumatic changes of the periodontium of marmosets (callithrix jacchus).	the systemic administration of steroid hormone (0.400 mg of dexamethasone every 2 days), during a 28-day period in marmosets (callithrix jacchus) produced modifications in the evolution of the experimental periodontal traumatism. the observed changes were osteoporosis and reduction of the periodontal fibers in quantity as well as a reduction of repair process, when compared to the control group that only received the action of the trauma from occlusion.	1976	815537
histochemical differences between the major salivary glands of the marmosets (callithrix jacchus and callithrix penicillata).	histoenzymologic differences between the parotid, paramandibular and submandibular glands were studied in six callithrix jacchus (four males and two females) and four callithrix penicillata (three males and one female). the acinous cells of the paramandibular glands showed a stronger reactivity for the diaphorases (nadh2-tr and nadph2-tr) and for a certain group of enzymes of the carbohydrate metabolism (f-1-6p ald, ldh, adh, g-6-pdh and 6-pgdh), lipid metabolism (alpha-gpdh, beta-ohbdh, alkalin ...	1976	827738
skeletal development in the foetal and neonatal marmoset (callithrix jacchus).	qualitative and quantitative measurements of skeletal development were performed on foetal marmosets in utero and on fixed specimens of both foetuses and neonates. the sequence of skeletal changes may be used to assess developmental status and the prenatal growth of the marmoset is compared with that of other primate species.	1976	823366
the common marmoset (callithrix jacchus jacchus) as a model for ethological research.	the uses and advantages of the common marmoset (callithrix jacchus jacchus) as an animal model for ethological research were examined. it was found that this species had advantages over old world primates for work on social behavior as a nearer approximation to the group structure occurring in natural conditions could be obtained in the laboratory. the small size of the common marmoset also made it easier to handle and cheaper to maintain. the adult female gave birth at five-month intervals and ...	1977	413004
testicular steroidogenesis in the common marmoset, callithrix jacchus.		1977	407949
topographically organized reciprocal connections between areas 17 and mt (visual area of superior temporal sulcus) in the marmoset callithrix jacchus.	with the aid of the techniques of tracing axonal pathways by anterograde fiber degeneration, and by anterograde (autoradiography) and retrograde (hrp-histochemistry) axoplasmic transport, it could be shown that area 17 projects in a topographically and visuotopically organized manner onto the temporal visual area mt. the fibers of this association system originate from pyramidal cells in layer iiic, and from the solitary cells of meynert; they terminate in layers iv and iii of area mt. a corresp ...	1977	404175
histochemical studies on the submandibular ganglia of marmosets (callithrix jacchus and callithrix penecillata).	the histochemistry of the neural cells was studied in the submandibular ganglia of 5 callithrix jacchus (3 males and 2 females) and 4 callithrix penicillata (2 males and 2 females). these cells contain neutral mucopolysaccharides, nucleoproteins and lipidic materia, but are apparently devoid of glycogen. it is impossible to demonstrate in them any reactivity for udpg-gt, phosphorylases, atpase at ph 6.3, leucine aminopeptidase and alanyl aminopeptidas. the reaction for the other searched enzymes ...	1977	142413
susceptibility of common marmosets (callithrix jacchus) to oncogenic and attenuated strains of herpesvirus saimiri.	adult common marmosets, inoculated with either of 2 oncogenic herpesvirus saimiri (hvs) strains, developed fatal lymphoproliferative disease within 23-25 days post inoculation (pi). the disease was identical to hvs-induced lymphoma in cotton-topped and white-lipped marmosets. common marmosets inoculated with an attenuated hvs strain developed persistent infection; virus has been recovered from cocultivated lymphocytes of these animals for more than 384 days pi.	1977	198565
the establishment of specified-pathogen-free marmosets, callithrix jacchus.	the establishment of 3 specified-pathogen-free marmosets (callithrix jacchus) during the period may 1969 to january 1973 is described. a brief history of the conventional breeding colony from which the animals were derived is given and hysterotomy and hand-rearing techniques are described.	1977	402500

urinary excretion of biologically active chorionic gonadotrophin by the pregnant marmoset (callithrix jacchus jacchus).	no significant correlation exists between the amount of biologically active marmoset chorionic gonadotrophin (mcg) in urine and results obtained with an immunological pregnancy test. the pregnant marmoset excretes large amounts of oestrogenic steroids, which must be removed, to prevent the enhancement of the response of the bioassay for mcg. more than 99% of these unconjugated and conjugated urinary oestrogens can be removed by extraction with acetone and ether. mcg is excreted throughout pregna ...	1977	414981
yersinia enterocolitica infections in non-human primates.	yersinia enterocolitica was isolated from ten non-human primates in the netherlands. the following species were represented: potto, senegalgalago, wooly monkey, black spider monkey, common marmoset, cottonhead tamarin, pigtailed macaque and lesser whitenosed guenon.	1977	418633
effects of gonadectomy and oestradiol treatment on plasma luteinizing hormone concentrations in the marmoset monkey, callithrix jacchus.	a heterologous double-antibody radioimmunoassay for marmoset lh is described in detail. the system uses niamdd rat lh-i-1 for iodination, niamdd rat lh-rp-1 as standard and anti-ovine rabbit lh 610v serum. the assay measures the level of marmoset lh in plasma and shows a maximum cross-reaction (b/bo = 50%) of 0.3% with other rat, human or bovine pituitary hormones. the heterologous assay has been applied to the measurement of the level of lh in the marmoset after gonadectomy and after the subseq ...	1978	415104
[autoradiographic studies on the distribution of 14c-piracetam in the simian brain].	autoradiography of the brain of the monkey callithrix jacchus 2 and 6 h after oral application of 200 mg 14c-piracetam/kg (2-oxo-pyrrolidine-l-acetamide-2-14c) shows that the drug is preferably concentrated in the cortex of cerebrum and cerebellum. this specific affinity of piracetam which was observed earlier in dog and rat is thus confirmed in the primate and seems to be species independent. beside the dominant cortical concentration there is a characteristic storage of piracetam in many nucle ...	1978	415743
composition of the milk of the common marmoset (callithrix jacchus) and milk substitutes used in hand-rearing programmes, with special reference to fatty acids.	analyses of marmoset (callithrix jacchus) milk were carried out to determine values for crude protein, lactose, total lipids, major minerals, and osmotic pressure. mean values were (g/100 ml): protein, 3.6; lactose, 7.5; total lipids, 7.7; minerals (mg/100 ml): sodium, 21.4; potassium, 54.3; calcium, 92.2; phosphorus, 22.8; magnesium, 5.0; chloride, 52.2; osmotic pressure, 354 mosm/kg water. similar analyses were conducted on 2 milk substitutes used in hand-rearing programmes. fatty acid analyse ...	1978	417007
physical, hormonal and behavioural aspects of sexual development in the marmoset monkey, callithrix jacchus.	measurements of growth, plasma progesterone and testosterone levels, and copulatory behaviour were obtained from captive marmosets from birth until 600-800 days of age. body weight and knee-to-heel length were similar for both sexes. males exhibited a neonatal testosterone surge from 15-100 days and testosterone levels began to rise again, coincident with the growth of the testis, at about 250 days. the males were copulating by 400-500 days of age. paired females were apparently ovulating and ab ...	1978	417178
use of the common marmoset, callithrix jacchus, in reproductive research.	a self-sustaining colony of common marmosets, callithrix jacchus, was established for reproductive research. methods of management were developed to ensure optimal breeding conditions for marmosets in captivity. studies of the reproductive biology and endocrinology of this species suggest that the common marmoset may be a suitable model for the human in certain aspects of the ovarian cycle, pregnancy, puberty and the hypothalamic and pituitary control of luteinizing hormone secretion. the rapid ...	1978	417331
a positive feedback effect of oestradiol on lh release in the male marmoset monkey, callithrix jacchus.	subcutaneous injections of oestradiol benzoate in oil, resulting in a sustained elevation of circulating oestradiol levels, induced an initial suppression of lh secretion, followed by a positive discharge of lh in castrated male and female and in intact male marmosets. oestrogen-induced lh release (producing maximum lh concentrations 24 h after the injection) was observed in 75% of castrated males and females. a positive discharge of lh occurred in 50% of intact males 28-36 h after oestrogen adm ...	1978	413918
aggression and flight behaviour of the marmoset monkey callithrix jacchus: an ethogram for brain stimulation studies.	the aggressive and flight behaviour of the common marmoset monkey (callithrix jacchus) is described and split into behavioural units, allowing analysis of agonistic behaviour evoked by electrical stimulation of the hypothalamus. the social context of the described units is also considered. c. jacchus shows clearly recognizable behavioural patterns. free-born animals are very timid and show typical flight reactions. within aggressive behaviour, two types of aggression can be distinguished: very v ...	1978	100171
threat, attack and flight elicited by electrical stimulation of the ventromedial hypothalamus of the marmoset monkey callithrix jacchus.	in order to elucidate whether relatively primitive primates show a similar topological organization of substrates mediating defense and flight within the ventromedial hypothalamus as has been found in other mammals, 15 marmosets (callithrix jacchus) were chronically implanted with a total of 57 electrodes for electrical stimulation. experiments took place in a familiar environment and under systematically altered conditions. all anatomical sites yielding vocal threat and short attacks were found ...	1978	100172
bacterial and mycoplasma flora of a laboratory colony of the common marmoset (callithrix jacchus).	a survey was carried out to characterise the bacterial and mycoplasma flora of a closed colony of marmosets, callithrix jacchus. bordetella bronchiseptica and staphylococcus aureus were the only potential bacterial pathogens isolated from the colony; candida albicans was also identified. s aureus and c albicans were the only organisms which were associated with macroscopic lesions or overt disease. post mortem examination of the animals proved only reliable method of establishing the presence of ...	1978	102075
studies with the baboon endogenous virus and its pseudotype of murine sarcoma virus in marmosets.	three marmoset species (saguinus oedipus oedipus, s. fuscicollis, callithrix jacchus) failed to show evidence of infection or disease following inoculation of baboon endogenous type-c virus (baev). cells infected with a kirsten murine sarcoma-baev pseudotype (msv[baev]) produced a progressive fibrosarcoma in s. o. oedipus and tumors in s. fuscicollis and c. jacchus which regressed. tumor formation is believed to be due to growth of inoculated, virus-infected cells and not transformation of marmo ...	1978	205851
overview of viral oncology studies in saguinus and callithrix species.	marmoset monkeys are highly susceptible to tumor induction by type c sarcoma viruses and primate lymphotropic herpeviruses. six experimental models were reviewed, three sarcoma models induced by rous, feline or simian sarcoma viruses and three models of lymphoproliferative disease induced by herpevirus saimiri, h. ateles or epstein-barr virus. relative susceptibility of cotton-topped (saguinus oedipus oedipus), white-lipped (s. nigricollis, s. fuscicollis subspecies) and commone (callithrix jacc ...	1978	205860
experimental infection of callithrix jacchus marmosets with herpesvirus ateles, herpesvirus saimiri, and epstein barr virus.	we inoculated common marmosets (callithrix jacchus) with herpesvirus ateles (hva), herpesvirus saimiri (hvs), and epstein-barr virus (ebv). hva-induced tumors contained several cell types, including giant cells reminiscent of the sternberg-reed cells observed in human hodgkin's disease. hvs and ebv did not induce tumors, although hvs was present in lymphocytes and elicited a strong antibody response. ebv elicited only a variable antibody response. we feel that more common marmosets should be use ...	1978	208678

histochemical observations on the taste buds of the marmosets (callithrix jacchus and callithrix penicillata).	the epithelial cells in the taste buds of c. jacchus and c. penicillata show a moderate amount of ribonucleic acid an a concentration of a pas-positive diastase-resistant material at their apical part. these cells are devoid of udpg-gt, phosphorylases, g-6-pa, alanyl aminopeptidase, leucine aminopeptidase, cholinesterase and mao; they present a weak reaction of f-1, 6-p ald, ldh, sdh, mdh, cytochrome oxidase, beta-ohbdh, nonspecific esterase and acid phosphatase and a stronger reaction to adh, n ...	1978	155939
sex determination in the common marmoset (callithrix jacchus).	the general morphology of the external genitalia was examined in 43 common marmosets (callithrix jacchus) ranging in age from newborn to adult. at birth, the scrotum was a small irregular fold of skin on either side of the caudal aspect of the penis. the testes were not present in the scrotum until 8--11 months of age. the scrotum covered the penis in the adult male, was devoid of fur, was covered by pearly while nodules, and presented a median raphe. in the young female, the pudendal pad closel ...	1978	416296
indoor-outdoor housing systems for a self-sustaining marmoset breeding colony.	indoor-outdoor housing of three types was designed, constructed, used and evaluated for housing a breeding colony of common (callithrix jacchus) and cottontop (saguinus oedipus) marmosets. all types were relatively inexpensive to construct, required minimal care, simulated a natural environment and allowed for some isolation between units and between individual runs within units.	1979	119116
'collaborative' rearing of marmoset triplets.	a system of management is described in which all 3 offspring from triplet births to callithrix jacchus can be successfully reared to weaning. hand-rearing techniques are applied to the offspring in turn without depriving them of the maternal and family influences necessary for normal behavioural development.	1979	113619
anomalous origin of the right subclavian artery in a marmoset (callithrix jacchus).	anomalous right subclavian artery in a one-day-old marmoset (callithrix jacchus) is reported. the anomalous vessel originated with the left subclavian artery from a short trunk off the arch of the aorta, then passed posterior to the esophagus, indenting it.	1979	119861
