摘要
目的:探索脉冲电磁场对周围神经再生的影响及其作用机理。方法:用SD雄性大鼠24只,在距梨状肌下缘约1cm处切断坐骨神经后原位吻合,随机分成1/2、1、2月3组,每组又分成对照和实验组,实验组用微电脑电磁脉冲发生器进行治疗,两组均在不同时间通过肉眼观察、肌电图检测及取材组织学检测。结果:实验组较对照组Walerian变性明显、加速、血管增生明显、纤维组织增生轻、神经再生及传导速度加快。
Objective : To explore the effects of pulsing electromagnetic field on
peripheral nerve regeneration as well as the mechanism were determined.Method:Twenty four
SD male rats were used in this study. Their sciatic nerves were cut at 1cm under the musculus
piriformis then were anastomosed. The rats were divided into three groups (0.5 month ,one
month and two months) at random.Then each of them was divided into the study subgroup and
the control subgroup . The electromagnetic field was used only for the study group.EMG, nerve
observation and histologic examination were performed for these groups repectively.Result:In
the study subgroup, accelerated Wallerian's degeneration, obvious blood vessels proliferation,
mild fibrous tissue proliferation and accelerated nerve regeneration were seen than the control
subgroup.Conclusion:The pulsing electromagnetic field could improve peripheral nerve
regeneration.
