弱电流音频电脉冲刺激加速神经再生的实验研究

Experimental study of speed up nerve rise again by a kind audio-frequency electric pulse to excite

本研究采用一种全植入式弱电流音频电脉冲刺激器 ,刺激动物神经加速其再生的实验 ,进行了组织学观察和神经电生理测定 ,实验表明 :(1)光镜观察发现 ,被刺激的损伤神经 ,周围无炎性反应 ,与周围组织无粘连 ,神经连接处无粘连。神经外膜上有再生毛细血管 ,神经连接处稍膨大。 (2 )电镜观察发现 ,被刺激神经在连接处有再生纤维 ,排列不太整齐 ,再生神经纤维变细 ,数目增多。周围可见疏松结缔组织。外膜周围有少量的巨噬细胞和肥大细胞。 (3)神经电生理测定 ,坐骨神经传导速度和复合肌肉动作电位 (M波 ) ,记录到微弱电信号波形。其结果表明 :弱电流刺激神经损伤组织 ,使其细胞功能增强 。

This research is an experiment to quicken nerve rise again by a kind entirely embedding audio-frequency weak electric current electric pulse stimulator to excite a nerve Do histology to observe and nerve electric physiology to determine The experiment to make known:(1)Optical glass observe to discover,Damnify nerve excited,It around no inflammtion,No participate in around organize to cohere,Nerve link part no cohere,Nerve surface have rise again bloodcapillary,Nerve link part a few expand (2)Electric glass observe to discover,Nerve excited of link part has rise again towline,Arrange no neat,Riseagain nervetowline change thin,Growin nmber,Around visible loose connective tissue,Nerve surface around a few hage cell and mast cell (3)Nerve electric physiology to determine,Sciatic nerve conduction speed and compound muscle action electric potential(M wave),Record weak electric sign wave It result to make known:Weak electric current excite damnify nerve histology,It can strengthen nerve cell function,Quicken nerve histology rise again
