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...

The functions of urine marking in a free-living population of house mice, Mus domesticus rutty

The urine-marking behaviour of free-living house mice,Mus domesticusRutty, was investigated in a poultry house where mice defended small territories and where evidence of previous marking behaviour was extensive. Thin smears of urine were found spread over most surfaces and concentrated...

Non-edible material elicits chewing and reduces the plasma corticosterone response during novelty exposure in mice

If mice were placed in a novel environment with metal foil or cardboard available, they chewed these materials. These animals had lower plasma corticosterone levels in novel cages than mice in the same environment without access to these chewable items....

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.

Intermittent stimulation and acceleration of puberty by urinary chemosignalsin female mice (Mus musculus domesticus)

A bedding of ground wood shavings was changed once each week. Pregnant females and female test mice were provided with cotton squares (Nestlets, Ancare Corp., Manhasset,NY; 4.8 X 4.8 X 0.6-cm thick) for making nests.

Environmental enrichment facilitates foraging behavior

Gerbils who had one hour per month access to a complex outdoor enclosure or who were reared in a large cage were more efficient in locating a feeding source than controls [reared/kept in small cages].

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...
