ABSTRACT

Objective To investigate the effects of micronutrients selenium(Se), vitamin E(VE), vitamin C(VC) and magnesium(Mg) on levels of TXA 2, PGI 2 in plasma of rats with hyperlipidemia induced by high fat and high cholesterol diet. Methods Sixty Wistar juvenile rats were randomly divided into five groups. Each group was fed with normal diet, high fat and high cholesterol diet (HFD), HFD+Se+VE+VC, HFD+Mg, and HFD+Se+VE+VC+Mg, respectively. After eight weeks, the rats were sacrificed for the detection of levels of lipid, TXA 2 and PGI 2 in the blood. Result Micronutrient complex (Se, VE, VC, and Mg) can significantly inhibit the increase of blood triglycerol, total cholesterol, LDL C and TXA 2 induced by HFD and can significantly increase HDL C. Conclusion Micronutrient complex (Se, VE, VC, and Mg) has the lipid lowering effect and can decrease TXA 2/PGI 2 ratio, which is beneficial to the prevention of atherosclerosis.
