Rhodiola decreases the expression of ?-smooth muscle actin in tuhulointerstitial of adriamycin-induced nephropathy rats / 基础医学与临床

ABSTRACT

Objective To find the effect of Rhodiola herb on the phenotypic transfer of epithelial cell in renal tubule of adriamycin-induced nephropathy rats.Methods The rat nephropathy model is established by adriamycin.For Rhodiola herb treated group,feed with Rhodiola herb 0.672 g/kg?d from the 4th week,for the control group and neohropathy group,feed with water [3 mL/(kg?d)].Kill the rats per batch at the week of 4th,8th,12th,16thand 20th week,observe the pathological change of nephridial tissue,test the expression of ?-SMA-protein of myofibroblast in the tuhulointerstitial.Results A semi-quantitative analysis of ?-SMA of rats at the 16th week in the nephropathy group is 6.24?0.57,which is obviously higher than that of Rhodiola herb treated group,3.84?0.28(P
