| genetic polymorphism and linkage of the sixth and seventh complement components (c6 and c7) in the common marmoset. | using polyacrylamide gel isoelectric focusing and standard specific hemolytic detection methods, genetic polymorphisms have been found in the sixth and seventh complement components (c6 and c7) in two laboratory groups of common marmosets. the c6 locus is highly variable and the products of six alleles were observed; three c7 alleles were found. comprehensive breeding data indicated that both sets of alleles are inherited in an autosomal codominant manner. many of the c6 variants differed only b ... | 1984 | 6424644 |
| ultrastructural aspects of spermatogenesis in the common marmoset (callithrix jacchus). | the pattern of normal spermatogenesis in the common marmoset, callithrix jacchus, is described and a system classifying the spermatogenic cycle into nine successive stages is presented. in contrast to most previous studies of spermatogenesis, the classification system developed in this study depends more upon the recognition of characteristic cell associations rather than upon identification of particular steps of spermatid development. the structurally simple acrosome of the marmoset spermatozo ... | 1984 | 6423594 |
| body weight changes throughout pregnancy in the common marmoset callithrix jacchus. | adult female common marmosets were weighed weekly for periods of 6-30 months. of 27 animals, 25 were pregnant at some stage of the investigation. patterns of body weight change throughout singleton, twin and triplet pregnancies were obtained and compared. maternal weight increase was dependent on the number of young in utero; however, little or no change in weight was observed during the first 13 weeks of gestation, irrespective of the number of offspring delivered subsequently. the overall mate ... | 1983 | 6423468 |
| correlations among measures of playfulness and skillfulness in captive common marmosets (callithrix jacchus jacchus). | infant sensorimotor and social skills, playfulness, and nonplayful behaviors were measured in common marmosets from 6 to 22 weeks old. different measures of skill showed a low concordance, implying that skill is a multiple rather than unitary attribute. significant correlations were found between the amount of social play infants performed from 11 to 13 weeks of age and their performance at 14 weeks in (1) competitive food tests with their mothers, and in (2) their ability to negotiate an obstac ... | 1984 | 6423428 |
| a comparison of tooth eruption patterns between two colonies of young marmosets (callithrix jacchus). | the tooth eruption patterns of two large groups of young living marmosets were compared. the eruption sequence was essentially similar and was consistent with previous studies based on smaller numbers of dead animals. at nine mo, however, one group was more advanced than the other, although their craniofacial growth patterns were similar. | 1984 | 6420451 |
| stabilities of some constituents of marmoset (callithrix jacchus) plasma under various conditions of storage. | the stability of various marmoset (callithrix jacchus) plasma constituents was investigated after storage at room temperature, 4 degrees c, and -20 degrees c. the method of sequential analysis ensured that the between-run bias of the methods of analysis used was drastically reduced, and the definitions of stability were linked to the imprecision of these methods. optimal conditions for storage for as long as 48 h depended on the analyte being measured. room temperature was optimal for cholineste ... | 1984 | 6418408 |
| isolation, characterization and comparative aspects of the major serum apolipoproteins, b-100 and ai, in the common marmoset, callithrix jacchus. | the two major apolipoproteins of marmoset serum have been isolated and characterized, and on the basis of physicochemical and immunological criteria are homologous with the human ai and b-100 proteins. marmoset apolipoprotein ai was the principal protein of high-density lipoproteins (hdl) and was purified by gel filtration chromatography and electrophoresis in alkaline-urea polyacrylamide gel followed by electrophoretic elution. purified marmoset apolipoprotein ai displayed an mr of approx. 2700 ... | 1983 | 6418212 |
| timing of ovulation and implantation in the common marmoset, callithrix jacchus, by monitoring of estrogens and 6 beta-hydroxypregnanolone in urine. | urinary estrogen and 6 beta-hydroxypregnanolone excretions have been determined in female marmosets by means of hptlc. the levels observed in cycling females during implantation and abortion are reported. hormone analysis revealed a characteristic pattern showing cyclic fluctuations of estrogens and progesterone. estrogen metabolites increase during the follicular phase up to 1 microgram/ml, the progesterone metabolite level rises to 1.2 micrograms/ml urine during the luteal phase. maximum value ... | 1983 | 6416225 |
| relationship between ovarian and placental steroid production during early pregnancy in the marmoset monkey (callithrix jacchus). | concentrations of progesterone, 17 alpha-hydroxyprogesterone, oestrone and oestradiol-17 beta in peripheral and utero-ovarian vein blood were measured during the first 60 days of pregnancy. the same hormones were also measured in peripheral blood samples from non-fertile cycles. peripheral levels of 17 alpha-hydroxyprogesterone, oestrone and oestradiol increased gradually during early pregnancy whereas concentrations of progesterone declined. the patterns of secretion of progesterone, 17 alpha-h ... | 1983 | 6415278 |
| placental transfer of hexachlorophene (hcp) in the marmoset monkey (callithrix jacchus). | autoradiography was used to study the distribution of 2,2'-14c-methylene-bis-(3,4,6-trichlorophenol) (hcp) in pregnant marmoset monkeys in early (day 30-50) and late (around day 120) gestation and in a newborn (11 days old) pup. radioactivity was present in the conceptus at all stages of gestation, although the foetal concentration was lower than the maternal. in the embryo an accumulation was observed in the neural tube and in the embryonic membranes. in the late foetus and newborn monkey the h ... | 1983 | 6408890 |
| plasma testosterone response to hcg stimulation in the male marmoset monkey (callithrix jacchus jacchus). | in adult animals the intramuscular injection of hcg was followed by a rapid rise in plasma testosterone levels within 2-3 h and at doses of 40 and 80 i.u. hcg this primary response was followed by a second peak of testosterone at 48 h. prepubertal marmosets also responded to hcg stimulation with a rapid increase in plasma testosterone levels within 3 h, but the magnitude of this peak was lower than that observed in adult animals and no biphasic pattern was observed. in adult and prepubertal anim ... | 1983 | 6403699 |
| sex steroids and their relationship to binding proteins in the serum of the marmoset monkey (callithrix jacchus). | a sex hormone binding globulin (shbg) similar to human shbg was identified in marmoset serum based on its gel electrophoretic mobility, isoelectric point and steroid binding properties. levels of serum shbg were measured in immature and mature males, immature females and females during the luteal phase and pregnancy; serum progesterone, 5 alpha-dihydrotestosterone (5 alpha-dht), testosterone, oestradiol-17 beta and oestrone were also measured. mean (+/- s.e.m.) concentrations of shbg in immature ... | 1983 | 6403644 |
| levels of circulating and urinary oestrogens during pregnancy in the marmoset monkey (callithrix jacchus). | the levels of immunoreactive oestrone, oestradiol-17 beta and oestriol in plasma and urine were measured during early, mid- and late pregnancy in the marmoset monkey. in plasma, unconjugated oestrone remained less than 2% of total (conjugated plus unconjugated) oestrone throughout gestation, whereas unconjugated oestradiol-17 beta increased from 3% of the total value in early and mid-pregnancy to 35% in late pregnancy. the reversal in the unconjugated oestrone: oestradiol-17 beta concentration r ... | 1983 | 6401813 |
| the second, intralaminar thalamo-cortical projection system. | in the marmoset (callithrix jacchus), hrp and 3h-apo-hrp were injected into various cortical regions and the positions of labelled neurons in the non-specific, intralaminar thalamic nuclei (n. centralis and centre m edian ) were investigated. although neuron populations projecting to the different cortical regions overlap widely, a coarse topology exists inasmuch as intralaminar neurons projecting to the posterior cortex were located more rostrally and those projecting to the anterior cortex wer ... | 1984 | 6331230 |
| hematologic and immunologic responses in common marmosets (callithrix jacchus) infected with plasmodium knowlesi and epstein-barr virus. | the hematologic and immunologic responses to infection with either the epstein-barr virus alone or infection with epstein-barr virus and plasmodium knowlesi were studied using common marmosets (callithrix jacchus). the assays performed included complete blood cell counts, determinations of natural killer cell activity, and determinations of antibody titers to epstein-barr virus early antigen, virus capsid antigen and the nuclear antigen. while no animal showed signs of lymphoproliferative diseas ... | 1984 | 6328114 |
| the structure and epididymal maturation of the spermatozoon of the common marmoset (callithrix jacchus). | maturation of the spermatozoon of the common marmoset (callithrix jacchus) during epididymal transit was investigated using light and electron microscopy. except for the caudal migration of the cytoplasmic droplet there were no apparent ultrastructural modifications, although interesting morphological features of the sperm head were observed such as the substructure of the acrosome and a waist at the equatorial region. alteration to the plasmalemma during maturation was reflected by an increasin ... | 1984 | 6325376 |
| respiratory disease associated with parainfluenza type i (sendai) virus in a colony of marmosets (callithrix jacchus). | an outbreak of acute respiratory disease was observed in a colony of marmosets (callithrix jacchus). parainfluenza type i (sendai) virus was isolated from the lungs and from throat swabs of 2 animals which showed clinical signs of disease. a rising titre of serum neutralizing antibody to the virus isolated was detected in several affected animals. approximately 50% of the colony showed clinical signs of disease, and 3 animals died. the duration of illness ranged from 3 to 16 days. | 1983 | 6306336 |
| fatal lymphoproliferative disease in a common marmoset (callithrix jacchus) following inoculation of ag876 strain of epstein-barr virus and a tumor-promoting agent: preliminary report. | we report here the development of a fatal lymphoproliferative disease in a common marmoset (callithrix jacchus) following inoculation of the ag876 strain of epstein-barr virus (ebv) and of the tumor promoting agent 12-o-tetradecanoylphorbol-13-acetate (tpa). the marmoset showed antibodies against ebv capsid and early antigens (vca, ea) but not against nuclear antigen (ebna). ebna was detected in impression smears from lymph nodes and liver, and the presence of the ebv genome was detected from th ... | 1983 | 6303683 |
| junin virus infection of callithrix jacchus: pathologic features. | infection of callithrix jacchus, a new world primate, with the prototype strain of junin virus produced a severe disease. the animals developed multifocal hemorrhages and characteristic microscopic lesions such as meningoencephalitis, interstitial pneumonia, lymphocytic depletion of lymphatic tissue, hepatocytic necrosis, and a variable decrease in bone marrow cellularity. high virus concentrations correlated with lesions, and with the presence of viral antigenic determinants as revealed by immu ... | 1983 | 6301303 |
| analysis of dr-like molecules on a marmoset epstein-barr virus-induced cell line using a monomorphic anti-human hla-dr monoclonal antibody. | mouse anti-hla d region-related (dr) monoclonal antibodies have been found to cross-react with peripheral blood leukocytes from one primate species, the common marmoset (callithrix jacchus). immunoprecipitates of radioactively labeled cells extracted from a marmoset epstein-barr virus-induced cell line were analyzed by one- and two-dimensional gel electrophoresis and compared with the dr antigens of a human lymphoblastoid b cell line. two chains of estimated molecular weights of 34 000 (alpha) a ... | 1982 | 6284521 |
| poxvirus infection in a colony of common marmosets (callithrix jacchus). | an epizootic poxvirus infection occurred in a colony of 80 common marmosets (callithrix jacchus) recently introduced to a laboratory facility. over an 18-week period, 29 of the monkeys exhibited skin lesions that persisted for 4-6 weeks. although eight marmosets died during the outbreak, their deaths were not attributed directly to the poxvirus infection. the skin lesions developed over the entire body surface including the soles and palms. initially characterized as erythematous papules, they q ... | 1982 | 6281571 |

| cross-protection in nonhuman primates against argentine hemorrhagic fever. | the susceptibility of the marmoset callithrix jacchus to tacaribe virus infection was investigated to perform cross-protection studies between junin and tacaribe viruses. five marmosets inoculated with tacaribe virus failed to show any signs of disease, any alterations in erythrocyte, leukocyte, reticulocyte, and platelet counts or any changes in hematocrit or hemoglobin values. no tacaribe virus could be recovered from blood at any time postinfection. anti-tacaribe neutralizing antibodies appea ... | 1982 | 6276301 |
| natural antibodies to ebv-vca antigens in common marmosets (callithrix jacchus) and response after ebv inoculation. | healthy common marmosets from two separate colonies, one in england and one in france, were found to have antibodies cross-reacting with epstein-barr virus structural antigens (ebv-vca). all seropositive animals were at least 2 years old. experimental ebv infection of marmosets of different ages led to seroconversion of inoculated weanlings. adult animals either developed antibody for the first time or showed an increase in their existing titers. both control and infected animals developed a pro ... | 1980 | 6265400 |
| herpesvirus saimiri: protective effect of attenuated strain against lymphoma induction. | an attenuated strain of herpesvirus saimiri (a-hvs) induced a persistent, latent infection in common marmosets. virus was recovered from circulating lymphocytes of infected animals and antibody response to virus-specified antigens was demonstrated over 3-12 months pi. a-hvs-infected common marmosets and animals without previous a-hvs exposure were challenged with oncogenic hvs (125-825 pfu); marmosets without a-hvs infection developed malignant lymphoproliferative disease and died 3 weeks pi whe ... | 1980 | 6265382 |

| hepatitis a and b: serologic survey of human and nonhuman primate sera. | sera of humans and seven species of nonhuman primates were tested by radioimmunoassay and enzyme immunoassay for the presence of hepatitis a antibody, hepatitis b surface antigen and antibody to hepatitis b surface antigen. the outcome of testing a total of 276 serum or plasma specimens was as follows: with the exception of squirrel monkeys (0%) and cotton-top marmosets (0%), a considerable percentage of all other species tested had detectable antibodies to hepatitis a virus: humans 45.9%, chimp ... | 1980 | 6253744 |
| an investigation of the effects of intracerebral injection in the marmoset of cytopathic cerebrospinal fluid from patients with schizophrenia or neurological disease. | in experiments designed to investigate transmission, cerebrospinal fluid (csf) from patients with schizophrenia and neurological disease (huntington's chorea and multiple sclerosis) which had been found to induce cytopathic effects in human embryonic fibroblast cell culture was injected intracerebrally into mice, hamsters and marmosets (small new world primates). no evidence was obtained of transmission to mice or hamsters. a total of 15 marmosets (callithrix jacchus) was injected intracerebrall ... | 1983 | 6226054 |
| further consideration of the learning impairment after aceperone in the marmoset: effects of the drug on shape and colour discrimination and on an alternation task. | ten marmosets (callithrix jacchus) learned to discriminate between pairs of small grey objects differing only in shape or small plain plaques differing only in colour, in a wisconsin general test apparatus. each day, each animal was presented with three consecutive visual discrimination problems in the order shape-colour-shape or colour-shape-colour. after aceperone, an alpha-noradrenergic antagonist, animals were impaired at learning the first but not the subsequent tasks of each trio. these re ... | 1983 | 6222386 |
| rapid regression of fetal adrenal zone and absence of adrenal reticular zone in the marmoset. | developmental changes in plasma dehydropiandrosterone (dha) and in adrenal histology were studied in several marmoset species (callithrix jacchus and saguinus labiatus, nigricollis, and fuscicollis) to evaluate these primates as experimental models for the study of fetal adrenal zone regression. newborn marmosets had a prominent fetal adrenal zone, plasma dha levels above 1000 ng/dl, and plasma dha sulfate (dhas) levels of 140 micrograms/dl. the fetal zone regressed dramatically during the first ... | 1982 | 6216097 |
| binding of human lymphocyte-specific monoclonal antibodies to common marmoset lymphoid cells. | commercially available monoclonal antibodies which bind to human lymphocyte subsets were screened for their ability to bind to lymphoid cells from the common marmoset callithrix jacchus. anti-leu-5 and t11 were the only pan t-cell antibodies which reacted strongly. none of the antibodies which bind human lymphocytes of the helper/inducer subpopulation reacted with c. jacchus cells and only one antibody, t8, specific for the cytotoxic/suppressor subset, bound to the marmoset cells. the two antibo ... | 1984 | 6200238 |
| blood pressure effects of renin inhibition by human renin antiserum in normotensive marmosets. | the effects on blood pressure of an antiserum against pure human kidney renin were studied in conscious and anesthetized (pentobarbital, 24 mg x kg-1 i.p.) small new world monkeys (common marmosets). the antiserum inhibited the enzymatic activity of renin by 50% in a dilution of 1:45,000 in marmoset and 1:50,000 in human plasma. the antiserum (0.2 ml i.v.) decreased blood pressure in conscious marmosets on normal sodium intake by 15 +/- 5 (sd) mmhg and after salt depletion by 31 +/- 13 mmhg. a c ... | 1984 | 6199985 |
| alteration of blood coagulation and complement system in neotropical primates infected with junin virus. | the neotropical primate callithrix jacchus infected with junin virus presented an acute disease with hematological and neurological manifestations and died 17 to 24 days after infection. this picture is similar to that of human argentine hemorrhagic fever (ahf). blood coagulation and complement studies were performed in ten c jacchus animals inoculated with 10(3) tcid50 of junin virus, the prototype pathogenic xj strain. four monkeys were used as normal controls. infected monkeys and normal cont ... | 1983 | 6197506 |
| inhibition of renin in the primate callithrix jacchus (common marmoset). | the effects of an antiserum against human kidney renin and of h-142, a peptide inhibitor of human renin, were studied in the primate callithrix jacchus (common marmoset). in severely volume-depleted (low-salt diet and repetitive injections of furosemide), conscious marmosets, the antiserum reduced blood pressure to the same extent as the converting enzyme inhibitor teprotide (-31 +/- 7 sem mmhg and -30 +/- 5 mmhg). in mildly volume-depleted (normal salt diet and single injection of furosemide), ... | 1983 | 6196144 |
| skin reaction in callithrix jacchus penicillata to phytohemagglutinin. | sixty marmosets (callithrix jacchus penicillata) were intradermally tested with phytohemagglutinin. it was possible to classify this population into three groups on the basis of the reactions: 1. negatives, 2. those which showed just local hemorrhage, and finally 3. a group which developed a wheal as well as hemorrhage. the biopsy at the site of the reaction demonstrated several microscopic foci. this finding contrasted with the homogeneous cellular infiltration found in the human controls. | 1982 | 6187198 |
| organophosphate poisoning in marmosets. | due to faulty use of a chlorpyriphos-diazinon combination as a pesticide within a laboratory animal house, 19 marmosets of 2 species (saguinus fuscicollis and callithrix jacchus) of 98 at risk died from organophosphorous poisoning (19%) mortality). the clinical signs were those of cholinesterase inhibitors. the morphological lesions consisted predominantly of haemorrhages in several organs, particularly the cns, and of bone marrow necroses. | 1982 | 6176756 |
| syncytium-forming virus of common marmosets (callithrix jacchus jacchus). | this communication describes the isolation and characterization of a new syncytium-forming virus of common marmosets (callithrix jacchus jacchus). the virus, isolated from skin explants and peripheral leukocytes of healthy animals, induced syncytia and subsequent cytolysis of several human, simian, and rodent fibroblastic cultures and induced a carrier state in mixed fibroblastic-epithelial or epithelial cell lines. cytoplasmic and nuclear viral antigen was demonstrated in infected cells by indi ... | 1981 | 6164648 |
| demonstration of ocular dominance columns in a new world primate by means of monocular deprivation. | we investigated the pattern transneuronally transported [3h]proline to the visual cortex of normal and deprived marmosets (callithrix jacchus). in the normal marmoset a continuous band of label was evident within layer iv of striate cortex. following injection of the closed eye of deprived marmosets, distinct fluctuations of label were apparent over the base of layer iv in both hemispheres. these results support the hypothesis that the presence of ocular separation of geniculo-striate afferents ... | 1981 | 6162527 |
| the postnatal development of the temporomandibular joint of the common marmoset (callithrix jacchus). | the temporomandibular joints (tmj) of 55 male and 50 female common marmosets (callithrix jacchus) with an age range of 1 day- to < 12-yr-old have been studied to extend the knowledge on the craniomandibular articulation of this primate. details of changes in the bone structure, gross and functional anatomy, and histologic appearance of the marmoset tmj during the neonatal period, infancy, childhood, adolescence, and adulthood are compared with those which occur in the tmj of man. it is concluded ... | 1982 | 6153018 |
| the vaccine potential of cell surface glycoproteins from trypanosoma cruzi. | an experimental trypanosoma cruzi 90 kda cell surface glycoprotein (gp90) vaccine, previously shown to be protective in mice is similarly effective in marmosets (callithrix jacchus jacchus). protection in the mouse is completely dependent on the adjuvant saponin and immunological studies confirm that gp90 is intrisically poorly immunogenic. both specific antibody and cell mediated immunity are potentiated strongly by saponin and the resulting protective immunity is long lasting (six months). it ... | 1984 | 6151689 |
| nasal and intrathalamic inoculations of primates with tacaribe virus: protection against argentine hemorrhagic fever and absence of neurovirulence. | callithrix jacchus marmosets were inoculated by different routes with two stocks of tacaribe virus, one from suckling mouse brain and another from human diploid mrc5 cells. all 12 primates inoculated by nasal route developed neutralizing serum antibodies without any clinical signs. all 6 primates receiving the mouse brain-tacaribe virus were protected against lethal challenge with pathogenic xj strain of junin virus, while protection was also conferred in 4 out of 6 primates receiving the diploi ... | 1984 | 6148851 |
| transplacental and direct exposure of mouse and marmoset to ethylnitrosourea: analysis of chromosome aberrations. | the effect of ethylnitrosourea (enu) on chromosomes of mouse bone marrow cells and transplacentally exposed embryonic liver cells was investigated. chromosome aberrations were found to be dose- and time-dependent. the maximum damage was seen 6 h after the exposure. chromosome aberrations were also induced in bone marrow cells and lymphocytes of marmosets (callithrix jacchus) directly exposed to enu. aberrations did not, however, occur in offspring whose mothers were treated with enu before conce ... | 1983 | 6137079 |
| junin virus infection of calithrix jacchus: haematological findings. | haematological changes produced by experimental junin virus infection of a platyrrhine monkey, callithrix jacchus were studied. normocytic and normochromic anaemia appeared after 7 days post infection (p. i.), and increased steadily until day 21 p. i. reticulocytes and circulating erythroblasts were elevated during the anaemia, reached a peak on day 7 p. i., and disappeared later. platelets and leukocytes showed a significant decrease from days 14 and 18 p. i., respectively. these alterations co ... | 1982 | 6127935 |
| a new approach to the role of noradrenaline in learning: problem-solving in the marmoset after alpha-noradrenergic receptor blockade. | nine marmosets (callithrix jacchus) were tested on a variety of visual discrimination learning tasks in a wisconsin general test apparatus with or without alpha-noradrenergic receptor blockade achieved by the administration of aceperone. after aceperone, animals were found to be severely and consistently impaired at learning the first task of each test session and to be impaired on new and repeated reversal learning. they were, however, unimpaired on learning another similar task in each test se ... | 1981 | 6114497 |
| presence of ph2-sensitive circulating interferon among callithrix jacchus marmosets. | significant and relatively stable levels of serum-interferon were demonstrated in a callithrix jacchus population. this circulating interferon was acid-sensitive in all cases, classifying it as immune or "gamma-type" interferon. our results in these hematopoietic chimeras suggest that the presence of immune-type or at least ph 2-sensitive interferon could be related to the presence of two allogenic lymphocyte populations in each marmoset. | 1984 | 6094815 |
| infectious mononucleosis-like response in common marmosets infected with epstein-barr virus. | callithrix jacchus marmosets infected with epstein-barr virus (ebv) with or without concurrent treatment with cyclosporin a (cysa) remained healthy. five marmosets given virus alone developed lymphocytosis and heterophile antibody. antibody to ebv capsid antigens (vca) appeared and remained at titers of 1:40-1:80 from 15 weeks onward. two animals produced antibody to the r component of early antigens (ea) from six weeks onward. five cysa-treated ebv-infected marmosets showed no increase in total ... | 1984 | 6094675 |
| ovulation in the marmoset monkey: endocrinology, prediction and detection. | circulating progesterone, oestrogens and lh were measured in female marmosets (callithrix jacchus) over the periovulatory period. progesterone concentrations increased in all animals within 1 day of the estimated day of ovulation, confirming the usefulness of this hormone for retrospective detection of ovulation. oestradiol-17 beta and lh both showed a preovulatory rise, but due to the large quantity of plasma required (oestradiol: 0.2 ml) and the length of time taken for the assay (lh: 2-3 days ... | 1984 | 6090570 |
| effects of fibre on digestibility and passage time in callithricidae. | the effects of fibre in a pelleted diet on food intake, digestibility of crude fibre, dry matter and energy, on passage time and consistency of faeces were studied in 2 species of callithricidae, callithrix jacchus and saguinus fuscicollis. coarse cellulose, microcellulose, wheat bran and shrimp meal (chitin = crude fibre) were tested in diets containing 2,4 and 6% total crude fibre, respectively. digestibility and passage time were determined by inclusion of 0.5% cr2o3 in the diet. both cellulo ... | 1984 | 6087023 |

| metabolism and tissue distribution of tobacco-specific n-nitrosamines in the marmoset monkey (callithrix jacchus). | three male marmoset monkeys (callithrix jacchus) were injected i.v. with the tobacco-specific carcinogen [2'-14c]n'-nitrosonornicotine (nnn) (20.3 mumol/kg body weight) or [carbonyl-14c]4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (nnk) (18.8 or 420 mumol/kg body weight). they were sacrificed 4 h later. tissue distribution was studied in two monkeys by whole-body autoradiography and by computer-assisted densitometric analysis of the autoradiograms. the autoradiograms showed a high level of rad ... | 1985 | 4053274 |
| sexual dimorphism in the postcranial skeleton of new world primates. | this study examines sexual dimorphism in 24 dimensions of the postcranial skeleton of four platyrrhine species: callithrix jacchus, saguinus nigricollis, saimiri sciureus, and cebus albifrons. the two callitrichid species show a relatively small amount of variation in the degree of sexual dimorphism among the different dimensions. variation is considerably higher in the two cebid species as reflected by a mosaic pattern of sexual dimorphisms with males being significantly larger than females in ... | 1985 | 4043875 |
| effects of oestradiol 17b, progesterone and testosterone upon proceptivity and receptivity in ovariectomized common marmosets (callithrix jacchus). | the sexual behaviour of eight pairs of marmosets was observed during blocks of 30 minute tests after the ovariectomized female partners were treated with physiological doses of testosterone, oestradiol and progesterone. the effects of an intra-vaginal progesterone treatment were also investigated. pre-ovulatory levels of oestradiol significantly increased the females' proceptive and receptive tongue-flicking displays and reduced the percentage of mounts refused. mid-luteal levels of progesterone ... | 1985 | 4034688 |
| cloprostenol-induced luteolysis in the marmoset monkey (callithrix jacchus). | a single intramuscular injection of 0.5 micrograms cloprostenol was not luteolytic on day 6 or 7 of the ovarian cycle (n = 3), but was luteolytic in some animals (3/5) on day 8 and 9 and luteolytic in all 23 animals treated between days 10 and 17 of the ovarian cycle, and in 7 animals treated between days 19 and 43 of pregnancy. luteal function was monitored by measurement of progesterone in peripheral blood using a simple and rapid non-extraction assay. there was a dramatic fall in peripheral b ... | 1985 | 3968650 |
| new cytogenetic techniques in the study of primate genome evolution. | fixed metaphase chromosomes of different species and genera of primates (five species of macaca genus and callithrix jacchus) have been studied after alu i restriction enzyme digestion and da-dapi counterstaining, in the attempt to determine some qualitative characteristics of their dnas and specifically of the dna localized in the heterochromatic components of the karyotypes. the results have been discussed in the light of those already published on humans, confirming the potentiality of this a ... | 1986 | 3943867 |
| an allometric study of hippocampal components. a comparative study of the brains of the european hedgehog (erinaceus europaeus), the tree shrew (tupaia glis), and the marmoset monkey (callithrix jacchus). | brains of western european hedgehogs, common tree shrews and common marmosets were perfused and stained according to timm's method. the volumes of hippocampal components were determined with semiautomated quantitative techniques and compared by allometric methods. the results support previous findings that the size of the hippocampus in marmosets and tree shrews is about twice that of the hippocampus of the european hedgehogs of the same body weight. three hippocampal substructures account for m ... | 1985 | 3939608 |
| observations on the interaction between adult group members, group members without rearing experience and infants in the common marmoset, callithrix jacchus. | this study describes the reactions of adult, rearing-experienced members of three callithrix jacchus families to interactions between animals without rearing experience and infants. the direct involvement of adult group members in situations in which inexperienced animals interact with infants decreases as the infants become older. inexperienced animals will approach infants more seldom, if adult, rearing-experienced animals are nearby. adult, rearing-experienced members of the group display pri ... | 2012 | 3937806 |
| the acute toxicity of sarin in marmosets (callithrix jacchus): a behavioral analysis. | in marmosets, the clinical signs of poisoning following the administration of sarin and the effects of sarin upon performance in three behavioral test models were investigated. the sensitivity of marmosets to the lethal action of sarin was shown to be greater than that of rodent species and rabbits but very similar to that of the rhesus monkey. doses of sarin ranging from 33 to 55% ld50, resulting in erythrocyte acetylcholinesterase inhibitions of 88% or more, were shown to disrupt the performan ... | 1985 | 3937760 |
| immunization of marmosets with trypanosoma cruzi cell surface glycoprotein (gp90). | marmosets (callithrix jacchus) have been immunized with a vaccine comprising a trypanosoma cruzi 90k cell surface glycoprotein and the adjuvant saponin; a combination previously shown to be protective in mice. immunization was by two s.c. injections one month apart and non-lethal challenge of homologous y strain t. cruzi was given one month after the booster immunization. no anti-t. cruzi antibodies were detected after the first immunization but high levels developed after boosting. immunization ... | 1985 | 3936239 |
| low-iodine diet for the production of severe i deficiency in marmosets (callithrix jacchus jacchus). | a low-iodine diet consisting of maize, peas (pisum sativum), torula yeast, meat meal, maize oil and added vitamins, minerals and amino acids was given to eight pairs of adult, common cotton-eared marmosets (callithrix jacchus jacchus). eight control pairs were given the same diet to which potassium iodate was added. both groups also received low-i apple and deionized water. the diet provided adequate nutrition, as confirmed by the maintenance of body-weight and good health. in the i-deficient ma ... | 1985 | 3933555 |
