Abstract

1 The toxicity of pinacolyl methylphosphonofluoridate (soman, GD), cyclohexyl methylphosphonofluoridate (cyclohe xylsarin, GF) and 2-dimethylaminoethyl-(dimethylamido)-phosphonofluoridate (GV) and the therapeutic efficacy of two oximes (obidoxime and HI-6) in combination with atropine against mentioned nerve agents were evaluated in mice. 2 The 24-h i.m. LD50 of GD was 101 micrograms/kg (99.5-104.0), LD50 of GF was 170 micrograms/kg (151.0-190.0 and LD50 of GV was 25.2 micrograms/kg (23.0-27.7). 3 The efficacy of two oximes, obidoxime (15 and 30 mg/kg) or HI-6 (15 and 30 mg/kg) in combination with atropine (21 mg/kg) was tested. HI-6 was significantly more effective in reducing mortality than obidoxime following poisoning with all three nerve agents. 4 Higher doses of both oximes showed significantly more effective therapeutic efficacy against all nerve agents studied.
