Single whole-body exposure to sarin vapor in rats: Long-term neuronal and behavioral deficits

Freely moving rats were exposed to sarin vapor (34.2 ± 0.8 μg/l) for 10 min. Mortality at 24 h was 35% and toxic sings in the surviving rats ranged from sever (prolonged convulsions) through moderate to almost no overt signs. Some of the surviving rats developed delayed, intermittent convulsions. All rats were evaluated for long-term functional deficits in comparison to air-exposed control rats. Histological analysis revealed typical cell loss...
