摘要: 目的: 观察人组织激肽释放酶(HTK)对大鼠坐骨神经损伤的修复效应。方法: 选取36只雄性SD大鼠,重量在180~220 g 之间,分离坐骨神经,造成坐骨神经挤压伤模型,然后随机均分成3组:对照组,自尾静脉每日注射生理盐水 2 mL;甲强龙组(SM组),自尾静脉每日注射甲强龙 30 mg/kg(稀释至 2 mL);人组织激肽释放酶组(HTK组),自尾静脉每日注射HTK 17.5×10-3 PNAU/kg(稀释至 2 mL)治疗。在术前及术后第1、3、5、7、9、11、13天各时间点测定坐骨神经功能指数(SFI),术后第14天取出坐骨神经干,测定动作电位传导速度(NCV)。结果: 三组大鼠SFI值在术后第1、3天均为-100左右。自第3天开始,HTK组和SM组SFI恢复的情况要优于对照组,有统计学意义(P<0.05)。在术后第14天HTK组和激素组的NCV值高于对照组,差异有统计学意义(P<0.05)。结论: 大鼠经尾静脉注射HTK,可促进坐骨神经损伤修复,神经功能恢复快。

Abstract: AIM: To study the repair effect of human tissue kallikrein (HTK) on sciatic nervous of rats.METHODS: Thirty-six adult male SD rats weighted 180-220 g were randomly divided into 3 groups. The control group was just injected with 2 mL salt water by caudal vain every day. The SM group was injected with methylprednisolone 30 mg/kg(2 mL)by caudal vain every day. The HTK group was injected with human tissue kallikrein 17.5×10-3 PNAU/kg (2 mL) by caudal vain every day. The sciatic functional index (SFI) at the day 1,3,5,7,9,11 and 13 after operation in all rats were calculated. The nerve conduction velocity of the sciatic nerve at the 14th day postoperation was observed.RESULTS: All rats showed -100 at day 1 and 3. The HTK group and the SM group showed a statistically significant improvement over the control group from the 3th day postoperation. The NCV of the HTK group and the SM group were greater than the control group (P<0.05).CONCLUSION: The repair effect of human tissue kallikrein (HTK) on sciatic nervous of rats was effective.
