摘要: 目的:研究荞麦糠皮提取物(BCE)对Ⅱ型糖尿病大鼠血糖和血脂的影响及其机制的探讨。方法:采用链脲佐菌素(STZ)和高脂饲料建立Ⅱ型糖尿病模型。成模大鼠随机分为模型对照组(M组)和荞麦糠皮提取物组(BCE组)。测定空腹血糖(FBG)及用正糖钳实验判断模型是否建立成功。测定各组大鼠血清中甘油三酯(TG)、总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)及游离脂肪酸(FFA)、谷丙转氨酶(ALT)、谷草转氨酶(AST)的含量。结果:使用STZ和高脂饲料建立的Ⅱ型糖尿病模型成功。BCE能够不同程度地抑制Ⅱ型糖尿病大鼠血清中FBG、FFA、TC、TG、ALT、AST水平的升高,还可明显升高血清中HDL-C水平。结论:BCE可明显影响Ⅱ型糖尿病大鼠血糖和血脂的水平,从而改善胰岛素抵抗。

Abstract: Objective: To study the effect of buckwheat chaff extract (BCE) on serum glucose and lipid profiles in type 2 diabetic rats and the underlying mechanism. Methods: Type 2 diabetic rat models were established by intraperitoneal injection of streptozotocin (STZ) and feeding high-fat diet and divided into model control group and BCE treatment group. Fasting blood glucose (FBG) and euglycemic clamp technique were used to examine whether type 2 diabetes was successfully induced. All rats were fasted for 12 h after the last administration and blood was taken and assayed for free fatty acids (FFA), triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Results: STZ and high-fat diet induced type 2 diabetes in rats. BCE inhibited the increase of FBG, FFA, TC, TG, ALT and AST in the type 2 diabetic rats to different extents but resulted in a significant increase in serum HDL-C level. Conclusion: BCE improves insulin resistance (IR) through affecting serum glucose and serum lipid profiles in type 2 diabetic rats.

Key words: buckwheat, buckwheat chaff extract (BCE), type 2 diabetes, serum glucose and serum lipid profiles, insulin resistance
