ABSTRACT
Objective To investigate the effects of Schisandrae Sphenantherae Fructus and processed with vinegar on lipid metabolism of rats with type 2 diabetes mellitus (T2DM). Methods The rat model of T2DM was induced by high fat diet plus STZ. The rats were randomly divided into blank group, model group, Schisandrae Sphenantherae Fructus high-dose group and low-dose group, and vinegar Schisandrae Sphenantherae Fructus high-dose group and low- dose group. The rats in each group were fed with the corresponding medicine for gavage for 30 d. FINS, FFA, TC, TG, HDL-C, LDL-C, and MDH, total protein content of liver tissue were detected. HE staining was used to observe the histomorphological changes of liver and pancreas in rats. Results Compared with the model group, Schisandrae Sphenantherae Fructus groups and vinegar Schisandrae Sphenantherae Fructus groups did not show obvious effects on improving FBG and FINS, but it could raise varying degrees of HDL-C and MDH, and reduce FFA, LDL-C, TC, and TG, among which vinegar Schisandrae Sphenantherae Fructus could significantly regulate metabolism in T2DM rats. Conclusion Vinegar Schisandrae Sphenantherae Fructus can enhance the lipid metabolism regulatory function of T2DM rats.
