Cytokine secretion in squirrel monkeys

Psychoneuroendocrinology, 1997
The squirrel monkey, a non-human New World primate, has several endocrine peculiarities, including a 10-fold higher plasma cortisol concentration than Old World primates, such as man. Glucocorticoids are known to have immunomodulatory properties. We therefore measured cytokine levels in supernatants of in vitro cultures of mononuclear cells from the ...

Nocturnal sleep in squirrel monkeys

Electroencephalography and Clinical Neurophysiology, 1974
Abstract The nocturnal sleep records of three squirrel monkeys over 12 h sessions were examined for 7 consecutive nights. The sleep records were described in terms of the percentage of time in each of the stages of Awake. Stages 1.2.3 4 and REM. The mean percent time spent in sleep was 82.4″ ″ of the recording period.

Composition of Squirrel Monkey Milk

Folia Primatologica, 1972
The gross composition of normal squirrel monkey milk was (in g/100 ml): lipids, 5.1; crude protein (N × 6.38), 3.5; lactose, 6.3; and ash, 0.3. The lipids, proteins, and ash were further characterized. This milk had many similarities to milk from other primates, and was intermediate in total protein and lactose concentration between milks from Old ...

Cobalt epilepsy in the squirrel monkey

Electroencephalography and Clinical Neurophysiology, 1970
Abstract Small amounts of cobalt powder will generate paroxysmal activity for 48–72 h in the unanesthetized squirrel monkey cortex. Using halothane anesthesia with a rapid recovery time, paroxysmal activity may begin within 30 min of cobalt application.

Intraprostatic spermatozoa in the squirrel monkey

The Prostate, 1988
AbstractThe recent observation of spermatozoa within the human prostate prompted this study to determine if spermatozoa were present in prostates of nonhuman primates. Six of 32 squirrel monkey prostates contained intraglandular spermatozoa. No associated pathologic lesions were found. Spermiophages were seen in one case.

Squirrel monkey

1992
Abstract Thorington (1985) classified animals in the genus Saimiri into two species; Saimiri sciureus, of which he proposed there are four subspecies: S.s.sciureus, S.s. cassiguarensis, S.s. boliviensis, and S.s. oerstedii, and S. madeirae. However, research on the taxonomy of Saimiri is continuing (for example, Van de Berg et al. 1987).

Heatstroke in a Colony of Squirrel Monkeys

Journal of the American Veterinary Medical Association, 1972
SUMMARY An episode of heatstroke in a colony of squirrel monkeys (Saimiri sciureus) was characterized by abnormal behavior, weakness, ataxia, emesis, diarrhea, and dyspnea. Four monkeys died, and pathologic evaluations revealed generalized circulatory disturbances similar to those recorded in cases of human heatstroke.

Sequential Amatching in the Squirrel Monkey

Psychological Reports, 1966
Three squirrel monkeys were trained to perform a sequential matching problem by use of a fading technique. One of three differently colored standard stimuli was presented on the left key when S responded on that key. A response on the right key then resulted in presentation of a comparison stimulus on the right.

Vestibular Ganglion of the Squirrel Monkey

Annals of Otology, Rhinology & Laryngology, 1982
The vestibular ganglia of adult squirrel monkeys (Saimiri sciureus) were studied with the aid of light and electron microscopy. The vestibular ganglia are formed by small and large neurons (perikarya). The perikarya's outermost surface is surrounded by 2–20 lamellae of compact myelin. The compact myelin sheath varies its thickness around one perikaryon.

Orthocephalization in the postweaning squirrel monkey

American Journal of Physical Anthropology, 1996
Twenty male squirrel monkeys (Saimiri sciureus boliviensis) raised in captivity were allotted to one of the following groups: weanling control (C6) sampled at 6 months of age; young control (C24) fed ad libitum on a control diet and killed at 24 months of age; and malnourished (M24) fed ad libitum on a low-protein diet and sampled at 24 months of age ...
