Commercial cotton nesting material as a predisposing factor for conjunctivitis in athymic nude mice

A colony of Hsd:Athymic Nude-nu mice was found to have an increased prevalence of conjunctivitis. It was theorized, because Athymic Nude mice lack the normal fur, i.e., guard hairs, and eye lashes, the fibers from nestlets can easily become embedded...

Behavioral and cardiovascular responses of male Sprague-Dawley rats to common husbandry and experimental procedures: Effect of housing density

Responses of rats housed alone or with another rat were assessed using radio-telemetry. We conclude that some common husbandry and experimental procedures [moving rats to a clean cage, s.c. injection, tail vein injection, exposure to urine and feces from stressed...

Preference of mice, Mus musculus, for different types of running wheel

Strong preference was shown for running wheels with plastic mesh flooring, rather than the standard metal rods only. The preference for the plastic mesh was present in mice of different ages from different sources, and in both choice and single...

Environmental enrichment enhances recovery of function but exacerbates ischemic cell death

These data demonstrate that early, intensive intervention after ischemia can improve functional outcome but that this is accompanied by increased brain damage. Careful consideration needs to be given to the timing of rehabilitation after stroke and related types of brain...

Behavioral and CV responses of female Sprague-Dawley rats to common husbandry and experimental procedures: Lack of effect of the estrous cycle

We conclude that some common husbandry and experimental procedures can induce stress-like physiological changes in female rats but, surprisingly, these changes are affected only slightly or not at all by the stage of the estrous cycle.

The effects of routine cage-changing on cardiovascular and behavioral parameters in male Sprague-Dawley rats

The objective of this study was to determine whether the blood pressure and heart rate of adult male Sprague-Dawley rats are affected by the routine animal husbandry procedure of moving animals to clean cages. Cardiovascular parameters were obtained by using...

Tickling induces reward in adolescent rats

In adolescent rats, 50-kHz vocalizations are most evident during tickling and rough-and-tumble play. The following experiments evaluated whether 50-kHz vocalizations reflect positive social affect by determining (1) if tickling is a rewarding event, (2) if social or isolate housing conditions...
