玉米膳食纤维对实验性高脂血症小鼠降脂作用的影响

探讨玉米膳食纤维（CDF）对小鼠诱导型高脂血症降脂作用的影响。选用雄性昆明小鼠70只，经高脂饲料诱导成高脂血症模型，按体重和血清总胆固醇水平均衡分为7组，其中6组分别给予添加一定量的玉米膳食纤维构成的高脂饲料，另1组以高脂饲料作为参照组，观察玉米膳食纤维对小鼠体重，食量的影响及每周测定血浆脂质变化。结果表明：添加量在5％以上时小鼠的血清总胆固醇（TC）、血清甘油三酯（TG）显著降低（P〈0．05）和血清高密度胆固醇（HDL-c）5周后有显著升高（P〈0．05）。当玉米膳食纤维的添加量为5％以上时，玉米膳食纤维具有明显的降脂效果。

Corn Dietary Fibre Effective on Depressing Blood Lipid for Experimental Hyperlipaemia Mice

To observe the effect of corn dietary fibre(CDF)on decreasing blood lipid for hyperlipaemia mice,70 experimental hyperlipaemia male Kunming mice which had been caused by high lipid diet,were divided into 7 groups.6 groups were fed by high lipid diet with certain amount of corn dietary fibre added,and one group was treated as the control.The changes of mice weight,intake,and mice blood lipid(TC,TG and HDL-C) were analyzed weekly.The results show that with addition of corn dietary fibre up to 5% and more,the levels of serum TC and TG are lower,and the HDL-C is higher,comparing with the control(p<0.05).The blood lipid depressing effect of adding corn dietary fibre above 5% is obvious.
