Comparison on morphological characteristics, growth curves and their responses to extracts of bovine pituitary in vitro between WFSC and Schwann cells from wallerian degenerating segments of rat's sciatic nerves was conducted.

结果表明：（1）体外培养的大鼠面神经和坐骨神经来源的雪旺氏细胞形态、表型、生长、增殖分化特点相同，对牛垂体提取物中的促雪旺氏细胞生长增殖因子的反应相似。

Methods: Serum-free conditioned media of Schwann cell cultures from facial and sciatic nerves of neonatal and Wallerian degenerating segments in adult rats were individually collected and concentrated by ultra-filtration with molecular weight cut-off at 30 000 and 10 000. The growth activities of FMNs in vitro were determined by means of MTT assay under the condition of serum-free medium added with different components of concentrated SC-CMs.

Significance:(1)The phenomenon that soluble proteins coming from sciatic nerve segment under going Wallerian degeneration make axonal number of the dorsal root ganglia decrease and axons adhere to each other are first observed in our essay.

变性神经段中可溶性因子能够促进神经元轴突的生长、轴突直径增加；通过形成浓度梯度诱导轴突生长的方向、减少背根神经节再生轴突数目和使背根神经节轴突之间相互粘附。

Twenty healthy male SD rats weighing 280-300 g were adopted to prepare acellular xenogenous nerve, 52 male Wistar rats weighing 250-300 g were adopted to prepare the 10 mm defect model of left sciatic nerve.

取健康雄性Wistar 大鼠52 只，体重250 ～ 300 g，制备大鼠左侧坐骨神经10 mm 缺损模型。

METHODS:①Sixty samples were randomly divided into two groups(test and contrast groups,n=30 respectively),and the sciatic nerves of the toad was isolated.Two sorts of solution(alkalinized and plain bupivacaine hydrochloride) were applied to a segent of nerve,and the amplitude of the action potential was measured.②The grouping method was the same as above.After destroying the cord above the third spinal vertebrae,two sorts of bupivacaine soultion in various concentration were injected into abdominal cavity of the toad.The leg′s flexing time was measured.

①离体坐骨神经法：取蟾蜍60只，制备坐骨神经标本，分两组，实验组和对照组各30只，测定不同浓度的两组布吡卡因对离体坐骨神经动作电位幅度的影响；②在体坐骨神经丛法：取蟾蜍60只，分组同上，破坏第三脊椎以上的脊髓后，将不同浓度的两种布吡卡因注入蟾蜍的腹腔内，测定其缩腿反射消失的时间。
