| 摘 要： | 目的探讨磁刺激疗法治疗坐骨神经损伤的临床效果及机制。方法将60只SD大鼠随机分为观察组、对照组各24只和假手术组12只，前两组制备坐骨神经损伤模型。制模后观察组给予表面场强为0．09T磁刺激，30min／d，1次／d；其余两组不予干预。各组分别于第2、4、8、12周采用免疫组化法检测L4-L5脊髓运动神经元内生长相关蛋白（GAP-43）表达，于12周末行电生理检查测定神经传导速度（MCV）。结果与对照组比较，观察组各时点GAP-43表达明显升高（P均〈0．05），术后第12周再生神经传导速度加快、波幅升高、潜伏时缩短（P〈0．05）。结论磁刺激疗法能促进大鼠周围神经损伤后MCV的恢复，其机制可能为增加损伤脊髓运动神经元中GAP-43的表达。
