Circadian and short-term variabilities in blood pressure and heart rate measured by telemety in rabbits and rats

Blood pressure (BP) and heart rate (HR) were measured by telemetry in conscious unrestrained rabbits to clarify the profile of their variabilities. The variabilities were assessed for two periods, 24 h (circadian rhythm) and 1 h (short-term variability), and compared...

The effect of housing conditions and simple experimental procedures upon corticosterone level in the plasma of rats

Non-specific stimuli such as environmental change, noise, handling, weighing and intraperitoneal injections all produce marked increases in plasma corticosterone levels which remain supernormal for at least 2 hr.

Impact of differential housing on humoral immunity following exposure to an acute stressor in rats

Housing rats in groups seems to be less stressful for the animals than housing them alone.

Behavioral evaluation of spatially enhanced caging for laboratory rats at high density

The L-shaped partitions of the HP [high perimeter] allowed the rats added perimeter area fro tactile retreat and wall contact. These added perimeters also increased the use of the center of the cage.

Preferences of mice and rats for types of bedding material

The results seem to indicate that size and manipulability are among the main determinants of the appreciation of bedding particles by laboratory mice and rats, and larger particles are preferred. .. In the test system with two test cages, [aspen]...

Environment, social interaction, and physical activity as determinants of functional outcome after cerebral infarction in the rat

Thus, social interaction was superior to wheel-running but an enriched environment allowing free physical activity combined with social interaction resulted in the best [motor] performance.

Environmental influence on outcome after experimental brain infarction

After permanent ligation of the middle cerebral artery the motor function of rats housed in an enriched environment, i.e. cages with opportunities for various activities.. is significantly better than in rats housed in individual cages. Preliminary studies suggest that social...
