摘    要:
目的:研究一侧坐骨神经切断后,脊髓第7腰段的神经细胞的凋亡变化。方法:用DNA原位末端标记法。结果:在坐骨神经切断1d后脊髓后角内的神经胶质细胞开始出现凋亡,到第2天达到最大值,白质内的胶质细胞也发生凋亡;脊髓灰质后角感觉神经元的凋亡指数大于前角运动神经元的凋亡指数。结论:坐骨神经切断后的第1天脊髓神经细胞发生凋亡,传入神经元的凋亡大于传出神经元的凋亡,神经胶质细胞在细胞凋亡过程中发挥重要作用。

关 键 词:坐骨神经  脊髓  脱噬作用

Abstract:
AIM: To study the apoptotic nerve cells on spinal cord of the rat following unilaterals sciatic nerve transection. METHODS: Using the method of TdT mediated dUTP- fluorescein nick end labelling, to identification the apoptotic nerve cells in seventh waist segment. RESULTS: The apoptotic neuroglia cells in the in dorsal horn of spinal cord came forth after the first day of sciatic never transection and it come to maximate on second day, glial cells in the whiter matter also had occurrence apoptosis. The apoptotic index of neurons in dorsal horn of spinal cord was bigger than neurons in the front horn spinal cord. CONCLUSION: It suggest that there is an occurrence apoptosis in spinal cord following sciatic nerve axotomy with the neuroglia and neuronal cells loss on 1 day. The apoptosis of afferent neurons are bigger than the apoptosis of efferent neurons, Neuroglia cells apoptosis may play a great action in the course of apoptosis of the spinal cord.
Keywords:sciatic nerves spinal cord  apoptosis
