摘要: 以高脂饲料配合链脲佐菌素(STZ)致大鼠2型糖尿病(T2DM)动物模型,研究酸味中药五味子、金樱子、山茱萸对T2DM大鼠血糖、氧化应激、脂代谢等的影响。结果显示,五味子、金樱子、山茱萸对T2DM大鼠糖脂代谢均有不同的调节作用;五味子组显著降低T2DM大鼠空腹血糖(FBG)、糖化血红蛋白(HbA1c)、空腹胰岛素(FINS)水平,升高肝糖原;调节游离脂肪酸(FFA)、总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白(HDL-C)、低密度脂蛋白(LDL-C)的代谢平衡,能降低T2DM大鼠肝脏还原型辅酶Ⅱ(NADPH)含量,升高T2DM大鼠肝脏谷胱甘肽过氧化物酶(GSH-Px)和肝糖原,从而改善肝脏糖脂代谢功能。研究结果表明,酸味中药五味子、金樱子、山茱萸均有改善T2DM高糖高脂状态的功效,以五味子对T2DM高糖高脂状态影响更为明显。

Abstract: The type 2 diabetes animal model induced by high-fat diet and streptozotocin (STZ) were used to study the effect of Schisandra chinensis,Rosa laevigata and Cornus officinalis with different doses on blood glucose,oxidative stress and lipid metabolism.The results showed that blood glucose (FBG),glycosylated hemoglobin (HbA1c),fasting insulin (FINS) levels were significantly decreased,but liver glycogen was increased,the metabolic balance of free fatty acids (FFA),total cholesterol (TC),triglyceride (TG),high density lipoprotein (HDL-C) were regulated;NADPH (NADPH) content in liver was decreased,meanwhile glutathione peroxidase (GSH-Px) and liver glycogen in liver were increased,these results indicated that the liver function in Schisandra group was recovered;The experiment exhibited all of the three Chinese medicines could improve T2DM high sugar and fat status,in which the Schisandra improve T2DM high sugar and fat status much better.

Key words: sour medicine, T2DM, glucose and lipid metabolism
