Effect of Puerarin on Insulin Resistance in Gestational Diabetic Mellitus Rats / 中药新药与临床药理

ABSTRACT

Objective To observe the effect of puerarin injection (PI) on insulin resistance in gestational diabetic mellitus(GDM) rats. Methods Rats with gestation for 5 days received onedose injection of STZ 35 mg/kg into subaortic caudal vein. After injection for 72 hours, rats with blood sugar over 13.5 mmol/L indicated the modeling being successful. Then the model rats were divided into treatment group (TG, using Puerarin), westernmedicine control group(WCG, using rosiglitazone) and model group (MG, using 0.9 % NaCl), 10 rats in each group .Ten normal gestational rats were used as normal control group (NCG, using 0.9 % NaCl).Two weeks later, the changes of blood sugar, Creactive protein (CRP) and tumor necrosis factor- ? (TNF- ? ) were observed. Results Compared with MG, the above indexes were improved in TG and WCG after treatment( P
