有机磷杀虫剂引起动物迟发性神经毒性问题正日益受到重视。在生产上必须对所使用的农药评价它对人及非靶标生物可能发生的危险及应用后的潜在影响。迟发性神经毒性是其中的一个重要指标。Johnson[1～3]用母鸡鸡脑作材料，研究有机磷化合物的迟发性神经毒性问题，发现只有当鸡脑
Organophosphorus insecticides caused by animal delayed neurotoxicity problems are receiving increasing attention. The pesticide used must be evaluated for its potential risks to humans and non-target organisms and their potential impact after application. Delayed neurotoxicity is one of the important indicators. Johnson [1 ~ 3] hen chicken brain as a material to study the delayed neurotoxicity of organophosphorus compounds and found that only when the brain of chicken
