摘　　要：[目的 ]探讨苯对周围神经系统的影响。 [方法 ]对苯接触观察对象 13人、苯中毒者 14人为接触组 ,另选无毒物接触史的工人 48人为对照组 ,应用神经肌电图检测方法进行运动和感觉神经传导速度测定。 [结果 ]接触组尺神经及下肢腓浅神经感觉传导速度显著慢于对照组 (P <0 .0 5 ) ,其余所检神经传导速度与对照组相比差异无显著性 (P >0 .0 5 )。接触组下肢腓浅神经感觉传导速度异常率显著高于对照组。正中神经远端潜伏期较对照组明显延长 (P <0 .0 5 )。[结论 ]苯对周围神经存在一定程度的影响 。Objective The aim was to study the effect of the benzene exposure and intoxication on the conduction velocity of peripheral nerves.[Methods] 27 observation subjects and patients with bonzene poisoning as a case group and 48 normal persons as a control group were examined. The conduction velocity of peripheral nerves was examined by electromyography.[Results] The sensory conduction velocity(SCV) of ulnar nerve and peroneal nerve is much slower,and the distal latency of median nerve is also longer in case group compared with control group(P<0.05). [Conclusion] Benzene is harmful to peripheral nerve system. The sensory conduction velocity(SCV) is more valuable than the motorial conduction velocity(MCV) in revealing harmful effect of benzene on poripheral nerves.
