摘要
本文对30名具有周围神经症状或体征的丙烯酰胺作业工人进行脊髓及大脑体感诱发电位研究,结果发现脊髓传导速度减慢,脊髓传导时间延长,但脊髓以上中枢传导时间未见改变,提示脊髓上行传导神经纤维受损,而脊髓以上的脑干皮层感觉传导纤维未受影响,脊髓体感神经传导束的损害与接触丙烯酰胺程度有关。听觉诱发电位各指标未见改变,提示听觉神经传导系统未受损害。
The results of spinal and cerebral evoked potential studies showed a de-crease of conduction velocity in spinal cord and a prolongation of spinal con-duction time in 30 acrylamide workers with neuropathic symptoms orsigns.The central conduction time over cervical cord was not changed.The re-sults indicate that damage to spinal ascending somatosensory fibres may haveoccurred without damage to brainstem-cortical tracts.The damage to spinalascending tracts was found to be related to the degree of acrylamideexposure.The brainstem auditory evoked potentials (BAEP) were not changedin the acrylamide workers.
