摘要
选用2月龄Wistar大鼠,在距梨状肌下孔0.5cm处切断右侧坐骨神经,近侧断端套入硅胶管,然后分别注入20μlSchwann细胞县液、层粘蛋白20μg/ml和生理盐水。4周后观察到L4(L5)节神经元存活率分别是90%、80%和72%(88%、73%和53%)。
After sciatic nerve resetion, we put the normal saline (NS), laminin (LN) and the cultured Schwann cells(SCs) respectively into the silicon chamber, which was sutured to the proximal end of sciatic nerve. At 4 weeks, the survival rates of the neurons in L4(L5) dorsal root ganglion (DRG) were 72%, 80% and 90% (53%, 73% and 88%) respectively. The acid phosphatese (ACP) activity increased while the cholinesterase(ChE) activity decreased significantly in the NS group. LN and SC proved to decrease ACP activity and increased ChE activity. These results showed that LN and SCs had protective effect on the sensory neurons in vivo, suggesting that LN and SCs are conductive to the regeneration of peripheral nerves and the recovery of their function.
