Hens were treated with organophosphorus compounds until signs of neurotoxicity developed. The sciatic nerves, spinal cord, and medulla were then examined histologically by the Marchi method, to determine the extent and distribution of demyelination. The lesions were proportional to the dose of compound injected, and the spinal cord was more sensitive than the sciatic nerves. It is suggested that the spinal cord, and not the sciatic nerves, is the main site of damage in clinical paralysis following dyflos poisoning.
用有机磷化合物处理母鸡,直至出现神经毒性迹象。然后采用马尔基氏法对坐骨神经、脊髓和延髓进行组织学检查,以确定脱髓鞘的程度和分布。病变程度与注射化合物的剂量成正比,脊髓比坐骨神经更敏感。研究表明,在敌百虫中毒后的临床麻痹中,主要损伤部位是脊髓而非坐骨神经。
