Bicyclic phosphoester and soman induced convulsion in rats. Both bicyclic phosphoester (0.26μmol /kg ip) and soman (0.49μmol/kg sc) caused the increase of cerebellar cyclic GMP from 4.0±1.1 to 30±5 pmol/mg protein, p<0.01 and 5.3±1.0 to 12±4 pmol/mg protein, p<0.01 respectively; plasma cyclic AMP from 32±14 to 70±40 pmol/ml, p<0,01 and 46±18 to 90土40 pmol/ml, p<0.05 respectively. Clonazepam blocked the increase of plasma cyclic AMP and cerebellar cyclic GMP induced by bicyclic phosphoester. Diazepam prevented an increase of cerebellar cyclic GMP which was induced by soman.
