Experiments were conducted to evaluate the effects of chronic buspiron
e (1 mg/kg/day) on the influenza A (PR-8/34) virus specific immune inj
ury in CD-1 mice exposed to a chronic auditory stressor. Treatment wit
h buspirone resulted in a decrease of the stress-induced increase of v
irus titers and pulmonar vascular permeability as well as in a reducti
on of the mortality of mice.
