Biologically, MGK-264 (N-octyl bicycloheptene dicarboximide) acts as a synergists for insecticides mainly pyrethrins and pyrethroids. It’s used extensively in combination with pyrethrin and piperonyl butoxide and also with personal insect repellent and cockroach repellents. But the toxic effect of MGK-264 in mamalians was a relatively little known therefore in this studies it was initiated to examine the toxic effect of MGK -264 in rats. For 5 weeks it administrated daily in each 250 mg and 500 mg of MGK-264 per kg of body weight in rats. 1) The body weight gain and the LYMPH (%) value in blood were observed a slight tendency to reduce in accordance with amount of dose and number treatment time. 2) The content of cytochrome P-450 and activity of NADPH-cytochrome c reductase were decreased in liver and those were observed some tendency in the kidney as liver but not significant. 3) The liver cholinesterase activity in the both 250 mg/kg and 500 mg/kg per kg of body weight with treated groups and the liver aniline hydroxylase in 500 mg/kg treated group were gradually decreased from 4 weeks after treated groups. In consequence it would sugested that the toxic effect of MGK-264 was low but in could offer hazard effect in liver and nervers system of rats if it was administrated move dose of MGK-264 and agumented in number of treated time.
