objective: research the pathologic changes and mechanisms of spinal cord anterior horn motor neurons, peripheral nerve and target muscles after peripheral nerve injury.
目的:探讨周围神经损伤后,脊髓前角运动神经元、周围神经及靶肌肉的病理变化、机制;
the number of the motoneurons in the cervical spinal cord anterior horn was calculated.
取出脊髓标本后,观察颈髓前角运动神经元数目的变化。
conclusions:peripheral nerve injury could induce spinal cord anterior horn motor neurons dead and the neuron death demonstrated some characteristic.
结论:大鼠坐骨神经损伤后,脊髓前角运动神经元的胞体有死亡,其死亡具有一定的特征。
conclusions: peripheral nerve injury can induce spinal cord anterior horn motor neurons dead, and the neuron death demonstrates its own character.
结论:大鼠坐骨神经损伤后,脊髓前角运动神经元的胞体有死亡,其死亡具有一定的时间特征。
conclusion:ngf is contributed to the regeneration of peripheral nerve, the marked motoneuron in spinal cord anterior horn increase siginificantly.
结论:外周神经损伤后,损伤局部应用ngf能减少其前角运动神经元死亡及脱髓鞘改变。
mophological changes in motor neurons in spinal cord anterior horn were observed.
作超薄切片,电镜下观察脊髓前角运动神经元胞体超微结构的变化情况。
