有机磷农药为有机磷酸脂或硫代磷酸类化合物,是一种毒性作用很强的农药,对人畜均有毒性。常用的农药有敌敌畏、1605、1059、敌百虫等。这类化合物对人体内的乙酰胆碱酯酶有很强的亲和力,它与乙酰胆碱酯酶结合,形成磷酰化乙酰胆碱酯酶和丁酰胆碱酯酶而失去活性,造成乙酰胆碱的大量积聚,使胆碱反应系统过度兴奋而出现中毒症状。在临床 Organophosphorus pesticides are organophosphates or thiophosphates and are highly toxic pesticides that are toxic to humans and animals. Commonly used pesticides dichlorvos, 1605,1059, trichlorfon and so on. Such compounds on human acetylcholinesterase has a strong affinity, it is combined with acetylcholinesterase, the formation of phosphorylation of acetylcholinesterase and butyrylcholinesterase and loss of activity, resulting in a large accumulation of acetylcholine, the choline Reaction system over-excited and symptoms of poisoning.
