摘要
实验用兔28只,观察溴甲烷染毒8周后动物四肢肌电图的改变。肌电图表现为运动单位电位时程延长、波幅升高和多相百分比增加,与对照组相比有明显地统计学意义(P<0.01),特别是双后肢出现同步电位及自发性纤颤和束颤电位。以上结果提示:溴甲烷可产生明显的神经毒性作用,特别是在对脊髓的毒性作用中,以主要损伤腰髓神经元而影响双下肢功能为著。
The electromyogram(EMG)of four limbs was observed in rabbits of methly bromide poisoning after 8 weeks.The EMG showed prolonged duration,high amplitude and increased percentage of polyphasic potentials(P<0.01)compared with the control group.Especially,the EMG of pelvic limb showed the synchronization voltage, pontaneous fibrillation voltage and fasciculation voltage.This results suggested that methly bromide poisoning injured nervous system and especially damage the nervous of lumber spinal cord.
