摘要:

Most mammals and all primates, except man, develop vibrissae on the face. Histologically, the sinus hairs around the mouth and across the brow ridges of rhesus monkeys resemble those of nonprimate mammals except for their smaller size and lack of skeletal muscle attachments. These follicles grow in especially great density along the glabrous borders of the mouth. Unlike the linearly arranged vibrissae on the muzzles of more primitive mammals, the sinus hairs of the rhesus monkeys are distributed in less clearly defined patterns around the facial disc. Studies of vibrissae in nonprimate species indicate that these sensory hairs function in relation to eye-blinking, orienting, and biting reflexes, or in conjunction with olfaction.

摘要:

During a behavioral study of free-ranging rhesus monkeys, non-pregnant females were observed to show sexual behavior both at mid-menstrual cycle and peri-menstrually. The basis of the dual estrous periods appears to be dual maxima in estrogen secretion. Peri-menstrual estrus may be an evolutionary vestige from a tupaiid-type sexual cycle. The occurrence of sexual behavior proximal to menstruation forces a redefinition of the term ‘estrus

摘要:

Luteinizing hormone (LH) levels were measured, using a bio-assay system, for three species of non-human primates. All experimental subjects were mature, cycling, non-pregnant females. Following several base line cycles, daily vaginal smears and urine were collected. Gonadotropins were extracted by the kaolin-acetone method. Ovarian ascorbic acid depletion test was used to determine the µg equivalents of LH in 32 h urine samples. Cyclic range of LH for M. mulatta was 1.4 to 6.3 µg, for Papio papio 0.4 to 5.5 µg, and Pongo pygmaeus 1.2 to 3.6 µg. Luteinizing hormone peaks appeared after ovulation as determined by the vaginal cytology in the P. pygmaeus and the M. mulatta. The midcycle peak of LH correlated well with the eosinophilic cell peak in the P. papio<

摘要:

Standard hematological techniques were used to determine total erythrocyte counts, total leukocyte counts, hemoglobin concentrations, and differential counts for several species of Lemuriformes maintained in captivity in Tananarive, Madagascar. The hematological values for these animals were compared with values for animals maintained in captivity in Durham, North Carolina. Significant differences in total leukocyte counts and in differential counts were found. These differences may be accounted for by different environmental conditions, including climate, housing, and infectious agents.
