铅对周围神经的组织病理学损害已为电镜观察所证实。但铅对作业工人周围神经电生理影响的临床研究报道尚不多。本文对接触较低铅浓度的52名作业工人检测了周围神经传导速度,探讨其亚临床影响。对象与方法一、观察对象1.铅作业组从事焊锡、熔铅、铸字等工种作业工人52名,其中男性15名(A组),年 Histopathological damage of lead to peripheral nerves has been confirmed by electron microscopy. However, there are only a few reports of clinical studies on the electrophysiological effects of lead on the peripheral nerves of workers. In this paper, 52 workers exposed to lower lead concentrations were examined for peripheral nerve conduction velocity to investigate their subclinical effects. Objects and methods 1.Objectives 1. Lead work group 52 workers engaged in soldering, melting lead, casting and other types of work, of which 15 men (Group A), the year
