The expression of activated p38 mitogen-activated protein kinase (MAPK) and activated MAPK transcription factors c-jun, c-myc and elk-1 were examined in rat cerebellum after soman poisoning to determine the pathogenetic mechanism of the non-specific long-term effects of nerve agents. Male Wistar rats were poisoned by intramuscular administration of soman at a dose 60 microg kg(-1) (70% LD(50)) and samples were taken 1, 7 and 14 days after poisoning, immunohistochemically stained and p-p38MAPK, p-c-jun, p-c-myc and p-elk-1 expressions were measured using image analysis. Control groups were administered with saline instead of soman. The expression of activated p38MAPK and c-myc increased 14 days after soman poisoning while c-jun and elk-1 expressions remained unchanged 1, 7 and 14 days after soman poisoning. Delayed activation of p38 MAPK and its targets might be involved in the pathogenetic mechanism of the long-term neurophysiological toxic effects of nerve agents.
