After 8 weeks of treatment,levels of fasting blood glucose(FBG) and glucagon(Glu) in serum were respectively assayed.Immunohistocmical study was adopted to analyze the expression of glucagon in islet cells.Results Compared with model control group,SMAE of middle and high dose remarkably reduced the level of FBG and Glu(P
