静脉输注脂肪乳剂对大鼠血清游离脂肪酸谱的影响

目的 研究静脉输注脂肪乳剂对大鼠血清游离脂肪酸的影响。方法 将24只雄性Wistar大鼠随机分成3组，每组8只。(1)对照组(NS组)：输人生理盐水，正常饲养；(2)长链脂肪乳组(LCT组)：静脉输注10％长链脂肪乳剂intralipid；(3)中长链脂肪乳组(MCT／LCT组)：静脉输注中长链脂肪乳剂lipofundin。两脂肪乳剂组大鼠以等能量、等氮量、等液量匀速连续输入“全合一”肠外营养液。于第8天取血标本进行血清游离脂肪酸测定。结果 两脂肪乳剂组各大鼠血清游离脂肪酸明显高于对照组，但两种脂肪乳组间差异无显著意义。结论 静脉输注脂肪乳剂能使大鼠血清游离脂肪酸明显升高。

The effect of fat emulsion intravenous infusion on serum free fatty acids in rats

Objective To study the effect of fat emulsion intravenous infusion on serum free fatty acids(FFAs) in rats.Methods 24 male Wistar rats were divided randomly into 3 groups,8 rats in each group.(1)Control group(NS),the rats were infused with normal saline intravenously and regular chow;(2)Group LCT,infused with 10% intralipid fat emulsion intravenously;(3)Group MCT/LCT,infused with 10% lipofundin fat emulsion. Group LCT and group MCT/LCT were continuously received equal calorie,nitrogen and volemin in 'All-in-One'solutions. Serum samples were drawn on the 8th day after PN for fatty acid determination. Results The FFAs in Group LCT and group MCT/LCT were remarkably higher than that in control group, but no difference between Group LCT and group MCT/LCT. Conclusions Fat emulsion intravenous infusion can increase the serum free fatty acids considerately.
