title: Effects of antidotes on soman-induced brain changes.
abstract: Rats were pretreated with either diazepam, atropine or benactyzine 10 min prior to soman injection. Local cerebral glucose use (LCGU) was determined during the seizure phase (15 min post soman) or pathology phase (72 h post soman). Diazepam and benactyzine pretreatment prevented convulsive activity, whereas atropine pretreatment only reduced the duration of convulsive activity after soman exposure. Each pretreatment agent had a unique impact on LCGU pattern during the seizure phase. During the pathology phase, the marked reduction in LCGU and the conspicuous brain damage associated with soman-induced seizures was minimized by all three pretreatments.
