Research of Establishing Hyperlipidemia Model in Rats with Fat Emulsion

Abstract

Objective To compare two ways of establishing hyperlipidemia model in rats with fat emulsion.Methods Thirty male SD rats were randomly divided into three groups,which fed with normal diet(normal control group),low concentration fat emulsion(low concentration fat emulsion group),and high concentration fat emulsion(high concentration fat emulsion group),respectively.All the rats were sacrificed and tested for serum total cholesterol(TC),triglyceride(TG),high density lipoprotein-cholesterol(HDL-C),and low density lipoprotein-cholesterol(LDL-C) in two weeks after establishment.Results The levels of TC,TG,HDL-C,and LDL-C in the high concentration fat emulsion group were significantly higher than those in the normal control group and the low concentration fat emulsion group(P0.05);the levels of TC,TG,and HDL-C in the low concentration fat emulsion group didn't significantly differ from normal control group(P0.05).Conclusions High concentration fat emulsion can be used to establish hyperlipidemia model in SD rats,low concentration fat emulsion is not suitable for establishing hyperlipidemia model in SD rats.
