Total of 50 Wistar rats were randomly divided into normal group, model group, fosinopril group, Cyprinus carpio decoction treated with high dose group and low dose group consisting of 10 rats respectively. Nephropathy models were established by injecting adriamycin through tail vein and treated with Cyprinus carpio decoction. Urinary protein excretions in 12 h, serum albumin, total serum protein, serum sodium and potassium were measured by biochemical assay. The pathological changes and the expression of AQP1, AQP2, AQP3 inrat kidneys were respectively detected by HE stain and immunohistochemiscal assay. The results indicated: 1) The urinary protein excretion in 12 h (proteinuria) increased significantly along the time longed modeling, while no significant increasing in Cyprinus carpio decoction treated group (F = 5.23 -?41.89, P Cyprinus carpio decoction treated group were higher than that in model group (F = 13.12 -?15.48, P Cyprinus carpio decoction treated group were higher than that in model group (F = 3.42 - 3.96, P Cyprinus carpio decoction with interventing groups reduced proliferation, less inflammatory cell infiltration;4) In model group, the expressions of AQP1-3 in the renal tubule and collecting duct cells increased significantly than those in normal group, and those in Cyprinus carpio decoction treated group decreased than those in model group (F = 3.97 -?6.19, P Cyprinus carpio decoction could reduced the urinary protein excretion and alleviate pathological lesion and edema with adriamycin-induced nephropathy by decreasing the expressions of AQPs in kidneys.展开更多
