Abstract:
AIM To study the effect of polysaccharides 2b from Mudan cortex (PSM 2b) on type 2 diabetes mellitus (T2DM) rats and explore its mechanism. METHODS T2DM rat model was established by low dosage streptozotocin and high sucrose fat diet. The drugs were administrated by ig for 5 weeks. The serum glucose was assayed with GOD POD method. Insulin was determined by radioimmunoassay. Insulin receptors of the plasma membrane from rat liver were determined with radioligand binding assay of receptors (RBAR). RESULTS PSM 2b could significantly lower fasting blood glucose (FBG), improve impaired glucose telarance (IGT) and dyslipidemia. It could also remarkably raise receptor total (RT2) of the low affinity insulin receptor (InsR) and insulin sensitivity index (ISI) in T2DM rats. CONCLUSION PSM 2b has an obvious therapeatic effect on T2DM in rats. Its mechamsm is relatively improve insulin resistance (IR) in T2DM rats by raising the number of InsR.
