ABSTRACT
Objective To discuss the effects of Liuwei Dihuang Decoction on expressions of TGF-β1 and complement regulatory protein CR1 of the renal on IgA nephropathy rats.Methods Forty SD rats were randomized into normal group, model group, tripterygium glycosides group and Liuwei Dihuang Decoction group after adaptive feeding for one week. Complex method was used to establish IgA nephropathy model. All administration groups were given relevant medicine for gavage for 4 weeks;urine routine, the number of urine erythrocyte and 24 h urine protein were detected;creatinine, urea nitrogen, total serum protein and serum alburin were detected from blood;the renal pathological changes were observed under light microscope by HE and Masson staining;the expressions of TGF-β1 and CR1 were detected by immunohistochemistry.Results Compared with model group,Liuwei Dihuang Decoction could significantly decrease the proteinuria and hematuria levels and renal fibrosis changes of IgA nephropathy model rats, reduce the expression of TGF-β1, and raise the expression of CR1 (P<0.05).Conclusion Liuwei Dihuang Decoction can delay the renal fibrosis in IgA nephropathy rats through reducing the degree of TGF-β1 and promoting the expression of CR1.
ABSTRACT
Objective:To study the protective effects of Shenmai injection (SMI,参麦注射液) on peritoneal mesothelial cell in rats with 5/6 nephrectomy. Methods:By using light microscopy and scanning electron microscopy the morpholgical structure changes of peritoneal mesothelial cell in rats with 5/6 nephrectomy caused (chronic)renal failure model of after the peritoneal didysis of SMI were observed at the same time the levels of C3 and IgG in peritoneal dialysate were observed also. Results:The SMI could promote the recovery and proliferation of injured peritoneal mesothelial cell increase the immunity function of abdomen in rats. Conclusions:The SMI has protective effect on peritoneal cell in rats with 5/6 nepherctomg the protecive effect related to improving regional defence function in abdomen.
