1951年在德国研制新农药丙胺氟膦时,在三名发生急性中毒的工人中有两名在治愈后10天发生双腿无力,其中一人发展到双腿麻痹,手和臂部分麻痹。因此停止试制这个农药。由于神经症状出现于有机磷急性中毒症状消失数天之后,故把这种毒作用称为迟发性神 When a new pesticide, Propamide, was developed in 1951 in Germany, two of the three workers who became acutely poisoned had weakness in their legs 10 days after they were cured, one of whom developed paralysis of the legs and partial paralysis of the hands and arms. So stop trial production of this pesticide. Because of neurological symptoms appear in acute symptoms of organophosphorus disappeared a few days later, so this toxic effect is called delayed deity
