在实验性神经损伤(test lesion TL)前一定时间,给神经一个损伤刺激称为条件损伤(conditioning lesion CL)。本文旨在观察CL对TL后神经再生过程及神经再支配肌肉后其功能恢复的影响。将大鼠分为仅有TL的损伤对照和在TL之前16天给予CL的CL组。在腓神经伸趾长肌标本上、用微电极记录膜电位(MP)和小 At some point before the test lesion TL, a lesion stimulus to the nerve is called conditioning lesion CL. The purpose of this paper is to investigate the effects of CL on the process of neural regeneration after TL and the functional recovery after the nerve is re-administered. The rats were divided into a TL-only lesion control and a CL group given CL at 16 days prior to TL. On the peroneal nerve extensor digitorum longus, the membrane potential (MP) was recorded with a microelectrode and was small
