Dehydroepiandrosterone and Exercise in Golden Hamsters

Physiology & Behavior, 1999
Dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) are adrenal androgens that have been associated with a sense of well-being in humans. We describe two experiments done to test the hypothesis that an increase in DHEA or DHEAS secretion is associated with the inclination to exercise using a hamster model.

Neurobehavioural development of the golden hamster

Neurotoxicology and Teratology, 1989
The aim of this study was to establish a developmental profile for the golden hamster by using a systematic sequence of test procedures. One experimentally naive litter was tested each day from 0 to 25 days of postnatal age. The appearance of developmental landmarks (physical features and reflexes), spontaneous behaviour in an open field, homing ...

Disseminated Mycobacteriosis in the Golden Hamster [PDF]

Journal of Veterinary Medicine, Series B, 1987
SummarySpontaneous disseminated mycobacteriosis was observed in a pet golden hamster and grossly characterized by severely enlarged feet and lymph nodes. This enlargement resulted from nonpurulent granulomatous inflammation with intracytoplasmic acid‐fast bacteria and Schaumann bodies.

Fertilization in the Golden Hamster

1991
Early studies of fertilization in mammals involved observations of gametes that had been flushed from the reproductive tract of mated females. The development in the early 1960s of methods for the in vitro capacitation of sperm and the in vitro fertilization for the golden hamster (Mesocricetus auratus) eggs allowed investigators better control of the ...

Maternal behavior in the primiparous and multiparous golden hamster.

Zeitschrift für Tierpsychologie, 2010
Changes in the normal behavior patterns seen during lactation in the female golden hamster have received relatively little attention in the past (Rowell 1961; Daly 1972). The purpose of this experiment was to characterize and compare maternal behavior in

Multiple hemoglobins in the golden hamster

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1970
Abstract 1. 1. Seven distinct benzidine-positive bands were found on starch-gel electrophoresis at pH 8.6 of the hemolysates from fetal, newborn and adult golden hamsters. Four of the seven benzidine-positive bands were analyzed and named Hemoglobins I, II, III and IV according to their increasing electrophoretic mobility.

Movements of the cranial vibrissae in the Golden hamster (Mesocricetus auratus)

, 2009
Vibrissae are highly refined vibrotactile receptors that are present on most mammals. The Golden hamster exhibits three different behaviours of its mystacial, supraorbital, and genal vibrissae.

Androgenic control of the harderian gland in the male golden hamster.

Journal of Endocrinology, 1977
In the golden hamster, there are marked sex differences in the Harderian gland. Male glands (which are heavier than female glands) possess two cell forms (Type I and Type II cells); female glands only exhibit the former.

Carcinogenicity of vinylethylnitrosamine in Syrian golden hamsters [PDF]

Journal of Cancer Research and Clinical Oncology, 1982
Syrian golden hamsters received weekly s.c. doses of 5.0, 2.5, 1.25 or 0.63 mg/kg b.w. vinylethylnitrosamine (VEN). As dose levels increased, average survival time decreased, tumor multiplicity increased as did the total tumor rate which was between 50% and 100%.

Volume Discrimination in Golden Hamsters

Perceptual and Motor Skills, 1978
To 8 subjects (golden hamsters, Mesocricetus auratus), having learned to discriminate between two cubic volumes of very different size, test-situations were presented to determine if the three spatial dimensions were taken into account during learning. The results show that width is the most used dimension.
