Abstract:
This article was aimed to investigate the effect of theXin-Jiang-Tang(XJT) Granules on activity of hepatic glycometabolic key enzymes and liver function in streptozotocin (STZ)-induced type 2 diabetes mellitus (T2DM) rats. Fifty male SD rats were randomly divided into the normal control group with 8 rats fed with normal diet, and other rats in the model group fed with high-fat diet for 4 weeks. And then, STZ (40 mg·kg-1) was peritoneally injected once to induce T2DM rat model. The model rats were randomly divided into the T2DM model group, metformin (0.15 g·kg-1) group, and high-dose (12.64 g·kg-1) and low-dose (6.32 g·kg-1) XJT Granules group. The intragastric administration was given once a day for 8 weeks. After 8-week intervention, fasting blood glucose (FBG), fasting serum insulin (FINS), glycosylated hemoglobin (HbA1c), hepatic glycogen, serum ALT, AST, ALP,γ-GT and the activity of HK, PFK, PK, and G6PDH were detected. The results showed that comparing with the model group, XJT Granules group can obvious reduce FBG, FINS, HOME-IR, HbA1c and liver function indexes such as ALT, AST, ALP,γ-GT levels (P < 0.05,P < 0.01), increase the content of hepatic glycogen (P < 0.01), and the activity of HK, PFK, PK and G6PDH (P < 0.05,P < 0.01). It was conclude that XJT Granules can remarkably regulate glycometabolism of diabetic model rats and the regulatory mechanism may be associated with the increasing of HK, PFK, PK and G6PDH activity, promoting the synthesis of hepatic glycogen, improving liver function, downregulating FINS level, improving insulin resistance and eventually decreasing the level of FBG and HbA1c of T2DM rats.
