三鹿降血脂奶粉调节血脂作用的研究

观察了三鹿降血脂奶粉调节血脂的作用。用Wistar品系雄性大鼠60只随机分为6组,全部饲以高脂饲料,在此基础上分别饲以蒸馏水、普通奶粉及3个不同剂量的降血脂奶粉。实验期45d,实验前后测量体重,并采用酶法测定血清总胆固醇(TC)、总甘油三酯(TG)及高密度脂蛋白胆固醇(HDL-C)。结果表明,实验前后的各组大鼠体重均明显增加,但各实验组间无显著性差异(P>0.05)。处理组大鼠血清TG水平显著低于对照组(P<0.05或P<0.01);高剂量降血脂奶粉组大鼠血清HDL-C水平显著高于对照组(P<0.05);各组大鼠血清TC水平则未见有显著性差异。结论,三鹿降血脂奶粉对实验大鼠体重无影响,但可以显著降低TG并可显著升高HDL-C水平。

Study on sanlu lipid-reducing milk powders' regulation on blood lipids

To observe the function of Sanlu lipid-reducing milk powders' regul at ion on blood lipids. 60 male rats were randomly allocated into 5 groups fed on f at rich diet as well as distilled water, common milk powder and lipid-reducing milk powders in different dose. Serum total cholesterol (TC), total glycerol (TG ) and high density lipoprotein cholesterol (HDL-C) were measured by enzyme meth ods and weight was also measured just before and after the trial period,45 days . Results all rats gain weight significantly, but no statistical differences wer e observed among groups. TG levels of rats in treated groups were significantly lower than that in control groups (P<0.05or P<0.01);HDL-C level in high level dose group was significantly higher than control group (P<0.05); no statistical difference in TC was observed among all groups. Conclusion Sanlu lipid-reducing milk powder had no effect on rats' weight, but can reduce TG and increase HDL-C level based on the trial results.
