Renal protective effects of superfine powder of rhodiola rosea on diabetic nephropathy in rats / 国际中医中药杂志

Objective To study the renal protective effects of superfine powder of Rhodiola rosea in diabetic nephropathy (DN)rats.Methods The DN rats model was established by one side nephrectomy and intraperitoneal injection of streptozotocin(STZ).Then rats were randomly divided into 6 groups:sham-operation group,model group,Rhodiola rosea common powder groups(3 g/kg·d-1),and superfine powder of low,medium and high dose groups (0.75、1.5、3.0 g/kg·d 1),10 rats in each group.Rats were given the relevant drugs respectively for 7 weeks.Finally the levels of fasting blood glucose (FBG),serum total cholesterol (STC),blood urea nitrogen (BUN),creatinine (Cr) and urinary protein (Upro) were detected.The kidney tissue was taken for histopathological observation.Results Compared with DN modelgroup [FBG,STC,BUN,Cr and Upro was (24.78±3.66)mmol/L,(4.07±1.32)mmol/L,(22.36±2.54)mmol/L,(86.78±7.47) μmol/L,(50.23±6.82)mg respectively],the rats in DN model group after treatment with common and superfine powder (medium and high dose groups) of Rhodiola rosea appeared different levels of improvement ofFBG [(18.67±2.74) mmol/L,(17.21 ±3.17)mmol/L,(15.48±2.46) mmol/L],STC [(3.33±0.87) mmol/L,(3.42 ± 0.74) mmol/L,(3.21 ±0.92)mmol/L],BUN [(15.43±2.04)mmol/L,(16.56±1.85)mmol/L,(12.44±1.36)mmol/L],Cr [(66.17 ± 4.43) μmol/L,(68.42 ± 5.06) μmol/L,(61.33±4.21)μmol/L] and Upro [(37.47±5.64) mg、(35.66 ± 4.72) mg,(27.37± 3.92) mg],P＜ 0.05.The pathologic changes of kidney tissue were improved,too.Conclusion Rhodiola rosea has a good renal protective effect in rats with DN.Furthermore,the superfine powder is more effective than the common powder in renal protective effects.
