The characteristics of morphological changes were focal degeneration and necrosis of muscular fibres at the motor end plates, involving swelling of mitochondria. dilation of sarcoplasmic reticulum and disappearance of Z lines. etc. The myopathy was completely controlled by im HI-6 (bispyridinium oxime, 10 mg/kg) immediately after soman poisoning or by pretreatment of im neomycin (100 mg/kg,  -60 min) combined with im gallamine  triethiodide  (10 mg/kg,   -15 min). Obidoxime  im  (10 mg/kg,   0 min),  hemicholine im  (0.2 mg/kg,   - 1.20 min)  or  iv MgS04  (40 mg/kg.  -2 min)  decreased the incidence of myopathy. At the motor end plates the rate of positive Ca2+ dyeing was correjated with the incidence of myopathy. r = 0.90.},
