Effects of puerarin on blood lipid and expression of aorta laminin B1 mRNA in streptozotocin-induced diabetic rats / 中国临床药理学与治疗学

ABSTRACT

AIM: To observe the effects of puerarin on blood lipid and expression of aorta laminin B_1 mRNA in streptozotocin-induced diabetic rats. METHODS: Diabetic nephropathy rats were induced by intraperitoneal injection of STZ, and the experimental rats were divided into normal control group, model group, and puerarin group. During and after the treatment for 12 weeks, the general state, blood suger(BS), triglyceride(TC), cholesterol, low density lipoprotein(LDL-C), high density lipoprotein(HDL-C), glycosylated hemoglobin(HbA1c) and glycosylated low density lipoprotein(G-LDL) were detected. Aorta alteration of tissue morphology was observed by H.E staining, and the expressions of laminin B1 mRNA were determined by in situ hybridization analysis. RESULTS: Diabetes mellitus and aorta lesion occurred in the two model groups. Puerarin could improve the general state, decrease the level of triglyceride(P
