The effect of fat emulsion intravenous infusion on serum free fatty acids in rats / 中国普通外科杂志

ABSTRACT

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.
