电针对大鼠坐骨神经损伤后轴突转运的影响

Effects of Electric Acupuncture on Axoplasm Transportation of Injured Sciatic Nerve in Rats

目的在于研究电针对大鼠坐骨神经损伤后的再生作用。方法：采用大鼠坐骨神经损伤手术模型，HRP追踪观察。结果：电针组的L4、L5脊髓前角和L4、L5脊神经节内的标记细胞数目最多，与空白组比较有显著性差异，中药组次之，西药组最少。结论：该研究初步证明神经损伤后应用电针治疗，周围神经与中枢神经已获得较好的连续性，是一种加速神经再生，提高神经功能恢复的有效手段。

To study the regeneration effects of electric acupuncture on the sciatic nerve injury.Methods: The retrograde tracing of HRP was used on sciatic nerve injured rats. Results: The count of labelling cell in anterior horn of spinal cord and spinal ganglion of L4 and L5 in electric acupuncture group ranks first. There is a significant difference comparing with that of model control group. The count of labelling cell in traditional Chinese medicine group ranks secondly. And Western medicine group ranks thirdly. Conclusions: Electric acupuncture therapy improved the connections among peripheral nerves and central nerves, is one effective method in quickening nerve regeneration and improving nervous function.
