五苓散对阿霉素型肾病综合征大鼠治疗作用的实验研究

Effect of Wuling Powder on Adriamycin-Induced Nephrotic Syndrome in Rats

目的观察五苓散提取液对大鼠肾病综合征的治疗作用。方法SD大鼠尾静脉注射阿霉素(ADR)建立肾病综合征模型。观察连续给药4周对大鼠24h尿蛋白、血清白蛋白、血清胆固醇、甘油三酯及肾组织病理学等方面的影响。结果24h尿蛋白:高、中剂量组及强的松、中西药交替给药组与模型组相比均有差异。血清白蛋白:高、中剂量组及强的松、中西药交替给药组与模型组相比较有显著性差异,强的松、中西药交替给药组升高白蛋白作用优于高、中剂量组。血清胆固醇:高、中剂量组及强的松、中西药交替给药组与模型组比较均有显著性差异,而高剂量组、中西药交替给药组与空白组比较未见差异。甘油三酯:强的松组与模型组比较无差异,而五苓散高、中、低剂量组及中西药交替给药组均与强的松组比较有显著性差异。结论五苓散提取液具有消除水肿、降低尿蛋白、降血脂、提高血清白蛋白以及减轻肾脏损害的作用,与强的松联合用药有协同作用。

Objective To evaluate the therapeutic effect of Wuling Powder (WLP) on adriamycin-induced nephrotic syndrome in rats. Methods Rat models of nephrotic syndrome were established by injection of adriamycin into tail veins of rats. The rats were divided into 7 groups: group A(normal control),group B (high-dosage WLP),group C (moderate-dosage WLP),group D (low-dosage WLP),group E (hydrocortisone),group F (hydrocortisone and moderate-dosage WLP extractive) and group G (model control). The influence of 4-week treatment of WLP on 24-hour urinary protein volume,serum levels of albumin,cholesterol and triglycerides as well as pathological changes of kidney tissue were assayed. Results 24-hour urinary protein volume of group B,C,E and F were significanuly lower than that of group G;Serum albumin level of group B,C,E and F differed from that of group G; Serum albumin level of group E and F were higher than that of group B and C;Serum cholesterol level of WLP groups (group B,C,E,F) was much lower than that of group G and the difference was insignificant between group B,F and group A;As for serum triglycerides level,three WLP groups and group F differed from group E while the group G not. Conclusion WLP not only can eliminate tissue edema and decrease urinary protein volume and blood lipid content,but also can increase serum albumin levels,thus it can protect the kidney from injury. There also have been showen that a synergistic action of WLP and hydrocortisone has been shown in the treatment of nephrotic syndrome.
