摘　　要：目的研究中药前健脾后补肾对力竭运动大鼠肾功能的影响及其作用机制。方法将24只雄性SD大鼠分为安静对照组、力竭运动组、力竭运动前健脾后补肾组,力竭运动后24小时取材,检测血清尿素氮、肌酐和尿蛋白含量,HE染色观察肾组织细胞,原位末端标记法(TUNEL)检测肾凋亡细胞。结果力竭运动前健脾后补肾组比力竭运动组的血清尿素氮、肌酐、尿蛋白及凋亡指数低(P<0.05),无类似于力竭运动组的肾组织坏死现象。结论力竭运动造成的肾功能降低可能与肾细胞凋亡、病理损害有关,前健脾后补肾能减轻这些变化,起到一定的保护肾功能作用。Objective To study the effect and mechanism of strengthening the spleen and tonifying the kidney on the function and apoptosis of kidney in rats. Methods The 42 male SD rats were randomly divided into quiet control group, exhausted exercise group and strengthening the spleen and tonifying the kidney group. Twenty-four hours after exhaustive exercise, the concentrations of blood urea nitrogen（BUN）, serum ereatinine and urinary protein were determined. The apoptosis in kidneys of rats was detected by TUNEL. The structure of kidney was observed in the HE stain. Results Comparing with the exhausted exercise group, the concentrations of BUN, serum ereatinine and apoptotie index were lower significantly （P〈0.05） and there wasn＇t necrosis of kidney tissues in the strengthening the spleen and tonifying the kidney group. Conclusion Strengthening the spleen and tonifying the kidney play a certain role in protecting the renal function by inhibiting apoptosis and decreasing necrosis of kidney tissues.
