ABSTRACT
Objective:To observe the effect and its mechanism of hemoperfusion on injured myocardium under acute toxication of methomyl in rabbits. Methods:Twenty-four rabbits were randomly divided into three groups:control group ( N group) , acute metho-myl intoxication group ( P group) , hemoperfusion group ( HP group) . P group and HP group was treated by methomyl intoxication, and with 2-hour sham-hemoperfusion and hempoperfusion respectively. Then the pathological changes of myocardium were observed under optical microscope. The activity of SOD and content of MDA in myocardium were measured by colorimetry. The experimental data were analyzed by SPSS 16. 0 package. Results:There were congestion, edema and other pathological changes in group P, while no obvious changes in N group and HP group. The activity of SOD decreased while MDA content increased in P group versus N and HP group ( P< 0. 05). Conclusion:Hemoperfusion can alleviate the myocardial injury induced by methomyl poisoning through the mechanism of the resistance to oxidative damage.
