[Intervention effects of tiaozhi jiangtang tablet on insulin resistance in rats with diabetes mellitus type 2].
OBJECTIVE
To observe the effect of Tiaozhi Jiangtang Tablet (TJT) on insulin resistance (IR) in rats with diebetes mellitus type 2.


METHODS
The model rats of diebetes mellitus were induced by intraperitoneal injection of streptozotocin (30mg/kg) and feeding with high lipid forage. The rats in the TJT group were treated with TJT and those in the metformin group treated with metformin as positive controls. The glucose infusion rate (GIR) was detected by glucose clamp technique after treatment for 8 weeks. At the same time, fasting blood glucose ( FBG), fasting insulin ( FINS), free fatty acids ( FFA), total cholesterol ( TC), triglyceride (TG), and high-density lipoprotein cholesterol (HDL-C) were measured respectively, and insulin sensitivity index (ISI) and HDL-C/TC calculated. The changes of insulin sensitivity and lipid metabolism were evaluated.


RESULTS
TC, TG, HDL-C/TC, FINS, and FFA significantly reduced in the TJT group as compared with those in the control group, while ISI and GIR significantly increased, the effects of TJT were similar to those of metformin.


CONCLUSIONS
TJT is effective in increasing insulin sensitivity and improving glucose and lipid metabolisms in rats with diebetes mellitus type 2.
