We examined the in vivo and in vitro effects of soman on aldolase activity. Male rats were killed at 4, 6, 9 and 12.5 min after subcutaneous (s.c.) administration of 90 micrograms/kg soman. At 4 min after treatment, aldolase activity was inhibited 55-90% compared to control in cerebral cortex, brainstem, mid-brain and cerebellum; and up to 50% of control in diaphragm and muscle. By 12.5 min, aldolase activity in all areas had returned to control levels except in the diaphragm, which still exhibited 36% inhibition. In vitro activity of rabbit muscle aldolase was not inhibited by 10(-3) M soman. In contrast, diisopropylfluorophosphonate (DFP, 10(-3)-10(-2) M) acted as a competitive inhibitor of aldolase activity in vitro. The results suggest that in vivo, soman effects on aldolase activity are transitory. Any long-lasting effects of soman on aldolase activity may occur only in the periphery, and not in the central nervous system.
