百草枯是应用极广的除草剂。人和动物接触百草枯能引起肺水肿、肺间质纤维化及肝、肾脏器的损伤。近十余年来,许多学者从生物化学角度对百草枯毒性作用机理进行了大量的研究,但迄今仍不清楚。本文研究了狗给予百草枯后不同时间血浆葡萄糖含量变化。同时又对血浆中考的松、儿茶酚胺和胰岛素含量进行 Paraquat is a very widely used herbicide. Human and animal exposure to paraquat can cause pulmonary edema, pulmonary fibrosis and liver, kidney damage. In recent ten years, many scholars have done a great deal of research on the mechanism of paraquat toxicity from the perspective of biochemistry, but so far it is still not clear. This article studied the changes of plasma glucose in dogs at different times after paraquat was given. At the same time on the plasma test of pine, catecholamines and insulin content
