Effect of Wuling Powder on Adriamycin-Induced Nephrotic Syndrome in Rats / 中药新药与临床药理

ABSTRACT

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.
