| heat-evoked responses of dorsal horn nociceptive neurons in the monkey. | locations and response characteristics of nociceptive neurons in the dorsal horn of the spinal cord were studied in urethane-chloralose anesthetized japanese macaques. there were two general categories of nociceptive neurons. neurons of the first type, nociceptive specific (ns) neurons, responded only to intense mechanical stimuli. neurons of the second type, wide dynamic range (wdr) neurons, were activated by touch and pressure but responded maximally to noxious mechanical stimuli. ns neurons w ... | 1983 | 6876505 |

| species difference in liver microsomal and cytosolic enzymes involved in mutagenic activation of n-hydroxy-n-2-fluorenylacetamide. | the mutagenic activations of n-hydroxy-n-2-fluorenylacetamide (n-oh-2-faa) by subcellular fractions of the livers of the sprague-dawley rat, c57bl mouse, hartley guinea pig, syrian golden hamster, and macaca fuscata fuscata monkey were examined for sensitivity to paraoxon, which inhibits a deacetylase but not an arylhydroxamic acid acyltransferase. the mutagenic activation by liver microsomes was almost entirely mediated by a paraoxon-sensitive enzyme in all the animals tested. in contrast, the ... | 1981 | 6944527 |
| the effect of prostaglandins on experimental tooth movement in monkeys (macaca fuscata). | local administrations of prostaglandins e1 or e2 combined with orthodontic tooth movement can approximately double the rate of tooth movement in monkeys compared to that of the control. macroscopically, no side-effect was observed in the gingiva and associated structures. | 1982 | 6960050 |
| cathepsins d from rhesus monkey lung. purification and characterization. | two types of cathepsin d (cathepsins d-i and d-ii) were purified from rhesus monkey lung to homogeneity as judged from disc gel electrophoresis. cathepsin d-i was purified about 2,000-fold with a 5.1% yield while cathepsin d-ii was purified about 2,300-fold with a 14.3% yield. both cathepsins d were rich in the lysosome fraction of the lung, but appeared to be present in part extracellularly. both showed a molecular weight of about 35,000 on sephadex g-100 chromatography, and about 41,000 on sod ... | 1980 | 6998976 |

| winter range utilization of a japanese macaque troop in a snowy habitat. | the winter range utilization pattern of a japanese macaque troop in a snowy habitat was studied. the vegetation areas essential for subsistence were found to be relatively undisturbed mixed and deciduous forests. the concept of essential resource area (era) is defined. our comparison among three troops in the same habitat in the past and present with different population densities indicated that the per capita era is quite important in determining the range area. this implies that the population ... | 1982 | 7068055 |
| species-specific glycoproteins of the human red cell membrane. | specific antiserum of human red cells was prepared from rabbit anti-human red cell serum by absorption with red cells of horse, hog, dog and japanese monkey. this antiserum proved specific for human red cells regardless of blood types abo and mn as demonstrated by the hemagglutination test. sialoglycoproteins were extracted with lithium diiodosalicylate and isolated through chromatographic procedures from human red cell membranes, and showed inhibitory activity for the specific antiserum as well ... | 1982 | 7072195 |
| comparison of the two methods of electroejaculation in the japanese monkey (macaca fuscata). | electrical parameters in two methods of stimulation, i. e. the rectal probe method under anesthesia and the penile method in consciousness, were examined in the japanese monkey (macaca fuscata). in rectal probe method, ejaculation occurred in almost all animals by the stimulation of intermittent charges of 10-15 volts at a frequency of between 3-5 impulses per second by using a monophasic alternating current of 60 cycles. in penile method, good results were obtained by a dc, square wave stimulus ... | 1982 | 7075683 |
| effects of picrotoxin upon response characteristics of wide dynamic range neurons in the spinal cord of cat and monkey. | the effects of a subconvulsive dose of picrotoxin (0.5 mg/kg) upon response characteristics of wide dynamic range (wdr) neurons in the spinal dorsal horn were investigated in cats and japanese macaques. after intravenous administration of picrotoxin, the low threshold mechanoreceptive field of wdr neurons were expanded, and the high threshold surround of the receptive field disappeared. concomitantly, responses of wdr neurons to noxious heat stimulation were abolished. it was suggested that picr ... | 1982 | 7078835 |
