【摘要】 文章主要用玉米皮 ,麦麸和红小豆皮三种膳食纤维 (DF)观察比较三种DF对大鼠血脂、排便量、睾丸周围脂肪垫及皮下和肠系膜上的脂肪重量的影响。结果表明 :三种DF均能显著降低大鼠血清总胆固醇 (TC)、低密度脂蛋白胆固醇 (LDL -C)含量和动脉硬化指数 (AI) (P <0 .0 1 ) ,明显提高高密度脂蛋白胆固醇 (HDL -C)含量(P <0 .0 1 ) ,并且此降血脂作用是玉米皮DF明显好于红小豆皮DF和麦麸DF(P <0 .0 5或P <0 .0 1 )。三种DF都能明显促进排便 ,粪便干、湿重均明显大于高脂对照组 (P <0 .0 1 ) ,而且玉米皮DF的作用也显著优于另两种DF(P <0 .0 5或P <0 .0 1 )。此外 ,玉米皮DF还能明显降低大鼠生殖器周围脂肪垫重量(P <0 .0 5)且体重增加值及饲料利用率也显著低于高脂组 (P<0 .0 5)。更多还原

【Abstract】 Three dietary fibers (DF) were extracted respectively from wheat bran (WDF), coat of corn (CDF) and red beans (RDF). Fifty Wistar male rats were divided into 5 groups at random, 10 rats each, fed with the three DF respectively for 35 days. The serum lipids, body weight, fat weight around genitals, and wet and dry weight of stool were observed. The results showed that the and Arteriosclerosis index (AI) of three DF experimental groups were significantly lower than that of the high lipid group (HL) which was short of DF; and high-density ipoprotein cholesterol (HDL-c) values of three DF groups higher than that of HL group (p<0.01). The effect of CDF was more sigmificaant than of WDF and RDF (p<0.05,p<0.01). Three DF groups all showed better excretion.更多还原
