Abstract

Paraquat poisoning results in damages of multiple organs including liver, kidney and lung, and antioxidants have been proven to have protective effects. As a novel free radical scavenger, 3-methyl-1-phenyl-2-pyrazolin-5-one (MCI-186), was introduced to clinical use recently, its protective effect was studied on acute toxicity of paraquat in male ddY mice. When paraquat (175 mg/kg) were given orally, the survival rate was only 8% on the 6th day of paraquat ingestion in Control Group mice. Protective effect of MCI-186 was most evident and the survival rate was 42% on the 6th day and 38% on the 14th day of paraquat ingestion, respectively, when mice were treated immediately. A delay of 30 min in treatment resulted in an abrupt reduction of the survival rate. These results suggested that MCI-186 used in acute phase of paraquat intoxication might serve as a clinically available antidote for attenuating paraquat toxicity.
