projections of the precentral motor cortex and other cortical areas of the frontal lobe to the subthalamic nucleus in the monkey. | corticofugal projections were examined by means of the autoradiographic tracer method in 21 macaca fascicularis. the labeled material was injected into the main body representation areas of the precentral motor cortex and into various regions of brodmann's areas 6, 8 and 9 of the frontal lobe. the ipsilateral subthalamic nucleus receives a moderately strong and somato-topically organized projection from woolsey's precentral motor cortex. this projection is mainly restricted to the lateral moiety ... | 1978 | 83239 |
location of taste buds in intact taste papillae by a selective staining method. | taste buds were found to stain strongly and selectively in intact papillae with highly acidic dyes such as ponceau s. in intact tongues the taste buds in the fungiform, circumvallate and foliate papillae of the cynomolgus monkey and in the fungiform papillae of the rat as well as the taste discs in the fungiform papillae of the frog could be visualized. this method enables a rapid location and counting of taste buds in taste papillae without preparing histological sections. in cynomolgus tongue ... | 1978 | 83317 |
attempts to reproduce amyotrophic lateral sclerosis in laboratory animals by inoculation of schu virus isolated from a patient with apparent amyotrophic lateral sclerosis. | a virus isolated from the csf of a patient who had amyotrophic lateral sclerosis for 7 years, and prolonged pleocytosis in the csf, was adapted to suckling mouse brain by subsequent serial blind passages. this schu virus belongs to the tick-borne encephalitis complex of the genus flavivirus (togaviridae). suckling mouse brain homogenate of the 13th passage was used for transmission experiments in various species of laboratory animals. golden hamsters infected subcutaneously fell ill after a numb ... | 1979 | 84063 |
complement profiles in monkeys subjected to aggregate (immune complex) anaphylaxis, and following injection of soluble and particulate polysaccharides. | complement profiles were established in four groups of macaca irus monkeys: (i) aggregate (immune complex) anaphylaxis was induced following immunization, with ovalbumin. upon challenge, systemic arterial pressure decreased from 115 to 50 mm hg (mean values) in 10 min. the complement profiles revealed decreases in: c1q to less than 10% of initial value within 5 min; c4 proportional to hypotension; c3 slowly to 60% at 24 h; c5, c6, c7, c8 and factor b to about 80% of initial value in 5--30 min. c ... | 1979 | 90656 |
has myelin basic protein received a fair trial in the treatment of multiple sclerosis? | autosensitization to some central nervous system antigen still remains one of the best hypotheses for the continuing pathogenesis of multiple sclerosis (ms). enough is now known about the cause, pathogenesis, and treatment of experimental allergic encephalomyelitis (eae) to test this hypothesis. reports of therapeutic failure of the encephalitogen myelin basic protein (bp) in the treatment of ms have their counterparts in similar therapeutic failures in eae. only highly inbred strain 13 guinea p ... | 1979 | 93873 |
myelin basic protein treatment of experimental allergic encephalomyelitis in monkeys. | treatment of experimental allergic encephalomyelitis (eae) in two strains of monkeys with large amounts of myelin basic basic protein (bp) fails unless an adjunct is also used. in both strains the adjunct by itself is more effective than bp by itself, but in the one strain which could be investigated sufficiently, the combination can be made almost totally effective in reversing eae. the adjunct varies with the strain of monkey, an antibiotic in macaca mulatta and a steroid in macaca fasciculari ... | 1979 | 93874 |
thyroid activity in a hypometabolic primate, the owl monkey (aotus trivirgatus). | serum levels of triiodothyronine (t3) and tetraiodothyronine (t4) were significantly lower in owl monkeys than in long-tailed macaques. these observations were considered to be consistent with the lower metabolic rate of the owl monkey. however, the absence of a significant difference in the levels of thyroid stimulating hormone (tsh) between the two species suggested a lower thyroid sensitivity to tsh in the owl monkeys. there was an inverse relation between levels of t3 and tsh in the owl monk ... | 1979 | 94828 |
aortic pulse wave velocity, elasticity, and composition in a nonhuman primate model of atherosclerosis. | aortic pulse wave velocity was determined in macaca fascicularis monkeys fed either atherogenic or control diets for 36 months. the foot-to-foot velocity and apparent phase velocities of the second through seventh fourier harmonics at a given diastolic pressure in the atherosclerotic monkeys were 1.5 to 2.0 times the values for the control animals. more than 80% of the aortic intimal surface of the atherosclerotic monkeys was covered with fibrous or fatty plaque, which approximately doubled wall ... | 1978 | 95906 |
direct administration of methotrexate into the central nervous system of primates. part 1: distribution and degradation of methotrexate in nervous and systemic tissue after intraventricular injection. | levels of methotrexate (mtx) measured by both 3h radioactivity and dihydrofolate reductase assays were determined in cerebrospinal fluid (csf), plasma, urine, and both neural and non-neural tissues at varying times after a single intraventricular injection into cynomolgus monkeys (macaca fascicularis). clearance of the mtx from csf was rapid after injection. a relatively constant level of 3hmtx was reached in plasma 2 1/2 hours after injection, and about 30% of the 3hmtx dose was excreted in the ... | 1978 | 96228 |
vasectomy increases the severity of diet-induced atherosclerosis in macaca fascicularis. | diet-induced atherosclerosis developed more extensively in vasectomized cynomolgus monkeys (macaca fascicularis) than in sham-vasectomized control monkeys fed the same diet. the effect was most pronounced in the abdominal aortas, carotid arteries, distal segments of the coronary arteries, and intracranial cerebral arteries. antibodies to sperm developed in all vasectomized monkeys, and complement and immunoglobulins were associated with atherosclerotic plaques in some of the vasectomized animals ... | 1978 | 96532 |

viscoelastic properties of the periodontal ligament and mucous membrane. | load deformation studies were carried out on the maxillary arches of three adult macaca irus monkeys using tooth-borne and tissue-borne plates. by means of an electronically controlled dynamometer, forces with different loading rates, creep, and simulated chewing loads were applied to the plates. the displacement was measured electronically relative to posterior teeth using a linear variable displacement transducer. the six main viscoelastic features noted by other workers for individual teeth u ... | 1978 | 100600 |
brief communication. comparative pharmacology of norcocaine in m. mulatta and m. fascicularis. | norcocaine was administered intravenously (0.05, 0.5, 5.0 mg/kg) to three chaired unanesthetized male rhesus monkeys and to three chaired male cynomolgus monkeys. respiration rate, heart rate and rectal temperature were monitored. in the rhesus monkeys tachycardia and hyperventilation resulted. however, similar qualitative and quantitative changes were not observed in the cynomolgus species. there was a statistically significant difference in the response to norcocaine across species. these resu ... | 1978 | 100791 |
metabolism of delta4-cis-pgf1alpha in the monkey. | this isomer of pgf2alpha is relatively resistant to metabolic degradation in the cynomolgus monkey. thus, 16-20 per cent of the amount injected was excreted unchanged in the urine. five metabolites with 20, 18, 16 and 14 carbon atoms in the skeleton were identified. the data are similar to those earlier seen in the rat and further support the idea that this analogue of pgf2alpha could have a long half-life time in the mammalian body and thus a long duration of its pharmacological actions. | 1978 | 100831 |
hypocholesterolemic activities of lk-903 and clofibrate in miniature pigs, cynomolgus monkeys and beagle dogs. | | 1978 | 101309 |
concentrations of oestradiol-17beta and progesterone in the peripheral plasma of the cynomolgus monkey (macaca fascicularis) in relation to the length of the menstrual cycle and its component phases. | ninety-three female cynomolgus monkeys were monitored throughout 647 menstrual cycles; 93.2% of these cycles were 22--37 days long and were normally distributed, with a mean of 29.2 days. menstrual bleeding generally lasted for 3--5 days and was not related to the length of the cycle. the levels of progesterone and oestradiol-17beta in the plasma were measured during the menstrual cycle in 30 monkeys. the concentration of oestradiol-17beta reached a mid-cycle peak on day 11 or 12 of the cycle. t ... | 1978 | 101640 |
weight and size of the placenta in cynomolgus monkeys (macaca fascicularis). | a gross anatomical survey of the placental development was carried out in 24 cynomolgus monkeys (macaca fascicularis) of 4, 5, 6, 7, 8, 9, 10, 15 and 20 weeks of gestational age. eight of the 24 placentas examined were found to be single discoidal and the remaining 16 bidiscoidal. the weight and size of placentas of each animal were measured. the average weight of the 20th week placentas was about 94 times heavier than that of the 4th week ones; the average diameter of the former was about 5 tim ... | 1978 | 101705 |
functional rehabilitation of ankylosed temporomandibular joints. | successful chrome-cobalt prostheses have been used to replace the condyle and glenoid fossa in six young macaca irus monkeys. in one group of two animals the left temporomandibular joint was replaced; in the second group the right joint and in the third group both temporomandibular joints were replaced. neither masticatory function nor ability to open or close the mouth was affected, and all the animals remained in excellent health, living in the colony for 9 to 10 months. a similar surgical pro ... | 1978 | 101929 |
pulpal and periodontal effects of electrosurgery involving cervical metallic restorations. | the pulpal and periodontal effects of electrosurgery involving teeth restored with class v cervical amalgams and nonrestored teeth were evaluated in three cynomolgus monkeys. electrosurgical current was delivered for 1 second with a fully rectified unit at an output intensity consistent with normal clinical usage. experimental conditions included electrosurgery involving restored teeth, electrosurgery involving unrestored enamel, restored teeth not subjected to electrosurgery, and teeth which we ... | 1978 | 101933 |
spermatophagy in the seminiferous tubules and excurrent ducts of the testis in rhesus monkey and in man. | the fine structure of cells capable of phagocytosing spermatozoa in the testes and epididymes of monkeys and men was studied by means of transmission and scanning electron microscopy. both resident cells, such as sertoli cells and epithelia of the rete testis, and free cells, such as macrophages (spermatophages) were found to phagocytose spermatozoa or fragments of spermatozoa in the seminiferous tubules and excurrent ducts. the spermatophages develop from precursor cells which invade the semini ... | 1978 | 102218 |
bone growth aud development of secondary ossification centers of extremities in the cynomolgus monkey (macaca fascicularis). | the development of so-called long bones in the extremity has been studied roentgenographically in forty-seven males and fifty-one females cynomolgus monkeys bred and reared at the national institute of health. the age of the females ranged from five months to eight years and nine months, and that of the males was from four months to seven years. in addition, the fetuses of six to twenty weeks of gestation age were examined for the time of appearance of ossification centers. as the biological par ... | 1978 | 102516 |
human and macaque mastication: a quantitative study. | significant differences exist between human and macaca fascicularis patterns of mandibular movement during mastication. macaque patterns display less asymmetry, more uniformity, and limited lateral excursions when compared to humans for mastication of the same food. different anatomical structures between the two species offer explanations of the different patterns that were observed. researchers should use caution when using macaques as models for human mastication. | 1978 | 102670 |
ultrastructural organization of the retinal pigment epithelium of the cynomolgus monkey. | the ultrastructure of the retinal pigment epithelium of the cynomolgus monkey is described. particular interest is focused on the morphological basis for the functions of the pigment epithelium as part of the blood-retina barrier, as a metabolically active cell layer and as a participant in photoreceptor outer segment renewal. | 1978 | 103359 |
treatment of established atherosclerosis during cholesterol feeding in monkeys. | a semipurified diet containing 43% of the calories as fat and 1.2 mg of cholesterol/cal was fed to cynomolgus monkeys (macaca fascicularis) for 6 months; the cholesterol content was reduced to 0.34 mg/cal for the next 18 months. during the latter period, the monkeys were assigned to 4 groups of 18 animals each and received the following dietary additions: a, none (controls); b, cholestyramine (5%, w/w); c, dextrothyroxine (0.003%); and d, wy-14,643 (0.45%). cholestyramine normalized plasma lipid ... | 1978 | 103561 |
breeding of cynomolgus monkeys through successive generations by indoor cage system. | vital statistics on the breeding through successive generations were presented for the cynomolgus monkey colony of nih, tokyo. the results of this retrospective survey clearly demonstrated the third (f2) and the fourth (f3) generations could be bred and reared successfully by the indoor caged-breeding system in which either individual timed-mating or group mating procedure was adopted. several important and difficult problems involved in the production of successive generations of the cynomolgus ... | 1978 | 104074 |
studies on acute and late stages of experimental central retinal artery occlusion in the cynomolgus monkey. i. intensity-amplitude relations of the d.c. recorded erg with special reference to the c-wave. | the main positive component of the c-wave of the erg is generated by the pigment epithelium-receptor complex, which is supplied from the choroidal circulation. occlusion of the central retinal artery (ocra) causes serious morphological damage only to the inner retina. an effect on the c-wave is therefore not primarily to be expected. in this study on five cynomolgus monkeys with unilateral, laser-induced ocra the c-wave was decreased, slightly in the early stage and markedly in the late stage. a ... | 1978 | 104542 |
studies on acute and late stages of experimental central retinal artery occlusion in the cynomolgus monkey. ii. influence on the cyclic changes in the amplitude of the c-wave of the erg and in the standing potential of the eye. | the slow (2-3/h) oscillations of the c-wave amplitude and of the standing potential of the eye (sp) were studied in the cynomolgus monkey during the acute and late stages after experimentally induced (laser photocoagulation) occlusion of the central retinal artery (ocra). whereas the healthy control eyes showed large cyclic variations in both the c-wave amplitude and the sp, no oscillations in the c-wave amplitude were observed in the ocra eyes at any stage, and the sp oscillations were barely d ... | 1978 | 104543 |
effect of ultrasound on testicular electrolytes (sodium and potassium). | the testes of 50 rats were placed in a cup filled with water and received 1 w/cm2 of ultrasound for 15 min. fluid was collected from the seminiferous tubules and rete testis of the treated and control groups at 1, 8, 12, and 24 hr intervals. ultrasound increased the sodium concentration in the fluid of the seminiferous tubules, decreased the sodium concentration in the fluid of the rete testis, increased the potassium concentration in the fluid of the rete testis, and decreased the potassium con ... | 1978 | 104674 |
early lens changes in macaca fascicularis monkeys under topical treatment with echothiophate or carbachol studied by slit-image photography. | cynomolgus monkeys were given topical treatment with echothiophate or carbachol, and the lens changes were followed by slit-image photography. both drugs caused an early retrodisplacement of the anterior zone of disjunction due to swelling of the most superficial lens cortex. deeper layers of the cortex did not swell. the exact cause of the swelling is not known, but there must be a true cholinergic link. accommodation as such is not the cause, since (1) the effect was seen also in a monkey eye ... | 1979 | 104934 |
aspirin inhibits development of coronary atherosclerosis in cynomolgus monkeys (macaca fascicularis) fed an atherogenic diet. | the effect of aspirin in the primary prevention of diet-induced atherogenesis in cynomolgus monkeys was studied. the diet consisted of 2% cholesterol and 10% butter by weight for 24 wk. six monkeys received only the atherogenic diet and five monkeys received the diet plus aspirin, 81 mg/monkey per day. aspirin did not affect plasma cholesterol levels or aortic atherosclerosis. platelet aggregation to arachidonic acid was almost completely suppressed. aspirin decreased significantly the number of ... | 1979 | 105014 |
effects of intrafollicular administration of gonadotropins in two species of nonhuman primates using laparoscopy. | direct administration of 0.5 iu of human chorionic gonadotropin (hcg) into the matured ovarian follicles of adult female saimiri sciureus resulted in ovulation in 45% of the animals treated. when purified ovine luteinizing hormone (lh) was administered, ovulation was observed in 55% of the animals while intrafollicular injection of saline had no effect. similar injections of hcg into matured follicles of macaca fascicularis would not cause ovulation but did result in a 55% increase in menstrual ... | 1978 | 105138 |
persistent cloaca in a cynomolgus monkey (macaca fascicularis). | a persistent cloaca was found to occur in a 15-year-old female cynomolgus monkey. this is the first case reported in a nonhuman primate. the embryological basis of this anomaly is discussed, and pertinent anatomical findings in this animal are reported which demonstrate the embryologic defect. | 1978 | 105140 |
mandibular function in galago crassicaudatus and macaca fascicularis: an in vivo approach to stress analysis of the mandible. | single-element and/or rosette strain gages were bonded to mandibular cortical bone in galago crassicaudatus and macaca fascicularis. five galago and eleven macaque bone strain experiments were performed and analyzed. in vivo bone strain was recorded from the lateral surface of the mandibular corpus below the postcanine tooth row during transducer biting and during mastication and ingestion of food objects. in macaques and galagos, the mandibular corpus on the balancing side is primarily bent in ... | 1979 | 105147 |
absence of indoleamine-accumulating neurons in the retina of humans and cynomolgus monkeys. | indoleamine-accumulating neurons have previously been detected in cats, rabbits, goldfish, chicken, pigeons, and cebus monkeys, and were therefore also looked for in humans and in old world monkey. cynomolgus irus. the monkey eyes were injected intravitreally with 50 microgram 5,6-dihydroxytryptamine, 5 microgram alpha-methylnoradrenaline, or both drugs simultaneously. the human retinas were incubated in either drug. previous observations on the distribution of dopaminergic neurons were confirme ... | 1979 | 105648 |
