摘要
目的评价了重组体人类神经胶质生长因子Ⅱ(rhCGF2)对大鼠坐骨神经挤压伤后运动功能恢复的效果。方法73只大白鼠被分为 3组。一组(n= 5)实施模拟挤压操作。在二组(n= 34)、三组(n= 34)中,每只动物选一 5 mm长的坐骨神经段承受 100 g挤压2 h。其中,三组用 rhGGF2治疗(1mg/kg挤压后皮下注射,1次/d,连续4 d),二组用相同量的载体治疗。通过计算坐骨神经功能指数(SFI)和测量趾长伸肌(EDL)强直收缩力来评价神经运动功能恢复。结果与二组相比,三组神经在术后 11-21d表现出显著的 SFI改善。三组肌肉收缩力强于二组,并从4— 14 d在 70 Hz和 100 Hz刺激下有显著性差异。组织学切片显示三组呈现较轻的轴突演变和较早的神经再生。结论用rhGGF2治疗坐骨神经挤压伤能有效的促进神经再生,进而显著改善其功能的恢复。
