摘要 断奶SD大鼠8窝32只,每窝4只随机分到4个组给予喂养,在正常饲料基础上分别加入7%的4种不同食用油喂养28天,这4种饲料的脂肪供热量皆为29.5%。4种油的饱和脂肪酸:单不饱脂肪酸:多不饱和脂肪酸(S:M:P)比值依次为:1.30:10.83:1:0.24:0.33:1;4.98:5.30:1;1.99:3.08:1。实验发现,第4号油组比第1号油组。大鼠血清中TC明显低,HDL-C/TC比值明显高,P<0.05。其他组间的差异,统计分析皆无显著意义。动物体重的增加,第4组比第1组高22.17%,但统计分析,组间差异无显著意义。 Male S. D. weaning rats were randomly divided into four dietary groups and fed with a normal diet containing No. 1,No. 2,No. 3 oil and mixed oil respectively for 4 weeks. All diets contained 29. 5% calories from fat and the S:M:P in oil ratios were 1. 3: 0. 83: 1,0. 24: 0. 33: 1, 4. 98: 5. 30: 1 and 1.99: 3.08: 1 successively. The results showed that serum TC of rats fed with mixed oil was ap- parently lower than that of rats fed with No. 1 oil,but the HDL-C/TC ratio in the former was much higher than that in the latter. The above changes in other 2 groups were insignificant statistically. And so was the weight gain in all 4 groups.
