摘要
目的探讨蚕茧、马齿苋对实验性2型糖尿病大鼠糖脂代谢的影响。方法利用链尿佐菌素建立2型糖尿病大鼠动物模型。随机分为糖尿病模型组、蚕茧组、马齿苋组、蚕茧+马齿苋组,另设正常对照组。治疗8周,检测大鼠血糖(Glu)、三酰甘油(TG)、超氧化物歧化酶(SOD),丙二醛(MDA)和谷胱甘肽过氧化物酶(GSH-Px)含量及活性,并计算胰岛素抵抗指数(HOMA-IR)。结果与DM模型组比较,蚕茧+马齿苋联合组血糖降低了53.3%(P〈0.01);TG降低了44.1%(P〈0.05);HOMA-IR降低了56.1%(P〈0.05);SOD、GSH分别升高了25%(P〈0.01)和8.4%(P〈0.05):MDA降低了53.6%(P〈0.05);其余各组间差异无统计学意义。结论蚕茧和马齿苋联合补充可明显改善糖尿病大鼠糖脂代谢、减轻胰岛素抵抗、并能有效提高其抗氧化能力、减少脂质过氧化产物的生成。
Objective To approach the effect of Silkworm Cocoon,Portulaca oleracea on the glucose and lipid metabolism to type 2 Diabetic rats. Methods type 2 diabetic rat models induced by STZ were randomly divided into diabetes model group,Silkworm Cocoon group,Portulaca oleracea group,Silkworm Cocoon+Portulaca oleracea group,and normal contrast group,after eight weeks' intervention,We analyze blood glucose(GLU), triglyceride(TG), SOD, GSH, MDA, calculate, the indexes of insulin resistance (HOMA-IR). Results compared with diabetes model group, the GLU in Silkworm Cocoon+Portulaca oleracea group decrease 53.3% (P〈0.01) ; The TG decrease 44.1% (P〈0.05) ; the Homa-IR decrease 56.1% (P〈0.05) ; SOD, GSH increase 25% (P〈0.01) 和 8.4% (P〈0.05) respectively: MDA decrease 53.6% (P〈0.05) ; other groups has no statistic difference. Conclusion The mixture group can obviously improve the glucose and lipid metabolism. relieve insulin resistance, significantly increase antioxidation, decrease the products of lipid peroxide.
