| Abstract: | Gentamicin(GM)was injected in order to damage the chick's cochlea. After one to 12 days application of GM,the cochlear nerve regenerating processes were examined by the trans mission electron microscop.The results showed that the axoplasms of the cochlea nerve fibers swollen. The axons disappeared and myelin lamellae disrupted following GM administration.12 days later.the schwann cells began to proliferate and enclose myelin debris,and a few microphages appeared too. Then exterior fibrocytes of the schwann cells were found as endoneurial border.These cells developed Bungner's structure and proliferated new regenerating myelinated nerves.The regenerating nerves had normal structure. This study demonstrated that the schwann cells in play a important role the regeneration of cochlear nerve. |
