RESUMO
Objective To study the protective effects of momordica saponins compounds on the kidney of type 2 diabetic mice. Methods The mouse model of type 2 diabetes was induced by feeding high￣fat diet for a week,followed by intraperitoneal injection of streptozotocin(STZ)at 150 mg.kg-1 .The mice were randomly divided into groups of normal control group(A), model control group ( B), rosiglitazone group ( C, 0. 4 mg . kg-1 ), the compounds at low￣dosage group ( D, 350 mg.kg-1 ) and high￣dosage group(E,700 mg.kg-1 ).The levels of fasting blood glucose,UCr,SCr,TGF￣β1 ,mALB,and HbAlc were determined respectively after being treated for 12 weeks. Results Compared with normal control group,the level of fasting blood glucose,SCr,TGF￣β1 ,mALB,and HbAlc in all other groups increased significantly (P<0.01);Compared with model control group,the level of fasting blood glucose,SCr,TGF￣β1 ,mALB and HbAlc in all treatment groups decreased significantly (P<0.01) ,the level of UCr increased markedly (P<0.01). Conclusion The Momordica saponins compounds can inhibit renal injury and exert kidney protective effect on type 2 diabetic mice.
