杀虫畏是一种苯乙烯磷酸三酯杀虫剂。作者对国产杀虫畏诱导肝微粒体酶的活力及其作用机理进行了初步探讨。实验结果表明;杀虫畏对大鼠肝微粒体酶具有诱导作用,此作用与微粒体蛋白合成有关,是通过促进蛋白质合成进行的。在哺乳动物体内,肝微粒体酶在杀虫畏的代谢解毒中具有重要作用,一定程度上从代谢的方面阐明杀虫畏毒性低, Insecticide is a styrenic phosphotriester insecticide. The authors conducted a preliminary study on the activity and mechanism of liver microsomal enzymes induced by domestic insecticides. The experimental results show that chlorfenuron has an induction effect on rat liver microsomal enzymes, and this effect is related to the synthesis of microsomal protein and is promoted by protein synthesis. In mammals, liver microsomal enzymes play an important role in the metabolic detoxification of chlorfenoxime, and to a certain extent explain the low toxicity of chlormethoxa from metabolic aspects.
