ABSTRACT
Objective To establish a rat model of hyperlipidemia and analyze the effect of conjugated linoleic acid (CLA) on lipid metabolism and expression of visfatin gene. Method High fat diet was used to establish the hyperlipidemia rat model. Blood was taken at four weeks after high fat diet feeding to analyze the level of glucose (GLU), cholesterol (CHO) and triglyeride(TG). The rats were divided into experimental group and control group after the hyperlipidemia rat model was established successfully. The experimental group rats were treated with CLA(0.8 mL /0.1 kg)orally for four weeks. The food intake and body weight were recorded. The rats were sacrificed, and both body fat and serum lipid levels were measured. Semi-quantitative RT-PCR was used to measure the expression level of visfatin mRNA. Result The hyperlipidemic rat models were induced by high fat diet successfully. The body weight, food intake and body fat in the rats of CLA experiment group were significantly decreased compared with that of the control group (P< 0.05). The level of GLU, CHO, TG and LDL in the experimental group were significantly lower than that in the control group (P< 0.05), but the serum HDL-C was increased in the experimental group. Semi-quantitative RT-PCR demonstrated that the expression level of visfatin gene of the experimental group was lower than that in the control group. Conclusion CLA can reduce the expression of visfatin gene and improve the lipid metabolism in hyperlipidemic rats.
