结果：(1)在无血清条件下单独培养的DRG，背根神经节的轴突数目众多，外形纤细弯曲，不成束，并且施万细胞和成纤维细胞稀少，所以可以排除两者对轴突生长的影响，为观察来源于变性坐骨神经段的可溶性因子对轴突生长的作用提供了有利条件；(2)在无血清条件下DRG和变性坐骨神经段联合培养，①先单独培养DRG，4天后待神经元轴突长出，再与坐骨神经段联合培养，观察到神经元的轴突数目减少，外形挺直，部分轴突之间相互粘附成束；②变性坐骨神经段和DRG同时联合培养，神经元的轴突数目明显减少，外形粗壮，轴突之间相互粘附成束；(3)有血清条件下单独培养DRG，轴突数目较多，外形挺直，长短不一，部分神经元的轴突之间相互粘附，施万细胞和成纤维细胞数目众多，观察到的轴突生长情况受到施万细胞和成纤维细胞的直接或者间接的影响。

METHODS The animal models of the transected sciatic nerve of 40 SD rats were established, which divided into 4 groups: normal saline group, nerve growth factor group, bFGF group and normal control group.

130 rats were randomly divided into five groups: 5F electroacupuncture treatment group, 50Hz electroacupuncture treatment group,100Hz electroacupuncture treatment group, the model group and the control group. 4mm defect was produced in the left sciatic nerve of each rat and silicon nerve guards were used to bridge the nerve defect not including the rats of the control group. After 10 weeks electroacupuncture treatment, gross observation, histological examination of the sciatic nerve were carried with method of HE stainning and S-100 immunhistochemical staining, Sevier-Munger stainnning. The histomorphometric examination of the triceps muscles were observed with measuring width muscle cell and the wet weight, and measuring the content of the heparin and the lactic aid of the triceps muscle with biochemistry methods.
