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...

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...

The effects of gentling on open-field behaviour of rats

Non-gentled rats showed higher frequencies and durations of passive motionlessness and higher proportions of loose stools and rigid movements during frighting situations than rats who had been gentled for three weeks.
