实验性神经植入肌肉神经终末再生的超微结构观察

Ultrastructure Observation on Regeneration of Nerve Endings in Experimental Direct Neurotization of Muscles

本实验选择16只新西兰白兔,神经原位植入比目鱼肌的标本,电镜下分时间组观察了神 经植入肌肉后,相关肌组织内神经再生过程,描述了肌间新老神经轴突的形态变化。植入神经自主 地肌间生长,24周内建立神经肌肉的连接。

Soleus muscles of 16 Newzealand rabbits were innervated with nerve implantation. The degeneration and regeneration of nerve endings in denerved muscles were observed by electron - microscope. The new MEPs were studied. Regeneration of nerve axons and the establishment of nerve - muscle connection were dis-cribed. A good muscular activity of the soleus was demonstrated spontaneously after 24 weeks of operation.
