Effect of acclimation to caging on nephrotoxic response of rats to uranium

It took rats a minimum of 3 to 5 days to behaviorally adjust [feeding/drinking] to being transferred to a different cage type.

Chronic noise stress and insulin secretion in male rats

The effect of chronic noise, followed by acute noise and forced swimming, on basal glucose and insulin levels was studied in adult male rats. Chronic noise did not modify basal levels of either measured variable before or after the exposure...

Effects of aging and housing in an enriched environment on sleep-wake patterns in rats

Rats housed in enriched versus barren cages show brain changes indicative of enhanced cerebral activity, and they spend more time sleeping.

Effect of stress on pharmocokinetics of amikacin and ticarcillin

Aberrant serum ticarcillin concentrations were measured when the animals were simply picked out, put on a laboratory bench, and wrapped in a towel to restrain them for blood collection. No aberration occurred in quasi trained rats who were handled daily...

Response of rats to the presence of stressed conspecifics as a function of day time

Corticosterone levels of non-handled rats increase when the animals witness stress reactions of conspecifics during forced restraint.

Transfer of effects from environmentally enriched and impoverishedfemale rats to future offspring

Experiments are described which demonstrate that manipulation of the environments of female rats even prior to pregnancy can significantly modify the behaviour of future offspring.

Effect of housing stress on the formation and development of tumors in rats

Tumor induction by 7,12-dimethylbenz[a]anthracene (DMBA) or inoculation with adenocarcinoma cells was studied in rats raised in groups (group G) or individually (group I) as well as in rats raised in groups and switched to individual housing at the beginning of...
