【摘要】 目的:探讨锰对周围神经传导速度的影响。方法:81名电焊工人和82名正常对照工人,应用神经肌电图检测方法进行周围神经传导速度测定。用石墨炉原子吸收分光光度法测定血锰浓度。结果:接触组电焊工人的血锰值(53.66±27.86)μg/L明显高于对照组(41.86±22.10)μg/L(P<0.05)。接触组所检测的腓总运动神经传导速度较对照组明显减慢,远端潜伏时较对照组延长,F波最短潜伏期(Fwave)较对照组明显延长,均具有显著性差异(P<0.05)。结论:提示锰不仅对中枢神经系统产生损害,对周围神经系统也产生不同程度的损害。周围神经传导速度检测可作为慢性锰中毒诊断的一个参考指标。更多还原

【Abstract】 Objective: To study the effect of the manganese exposure on the conduction velocity of peripheral nerves.Methods: Eighty-one subjects with manganese exposure as a case group and 82 normal workers as a control group.The conduction velocity of peripheral nerves was examined by electromyography.(Results:) The results showed that there was a significant difference in the peripheral conduction velocity in which the movement conduction velocity was much slower,the F wave shortest latency and the distal latency was longer in the case group(P<0.05).Conclusion: Manganese was harmful to not only the central nerve system but also the peripheral nerve system.The peripheral nerves conduction velocity can be used as a reference parameter for diagnosis of the chronic manganese intoxication.更多还原
