Abstract: Objective:To study the LDL oxidation in hypercholesteremia rats and the effects of atorvastatin.Methods:The experimental model of hypercholesteremia was established in rats by ig. fat emulsion. 30 wistar rats were sub-divided randomly into the control group、the model group and the atorvastatin group(5 mg/kg·d). After 4 weeks, the serum TC、LDL-c、HDL-c、SOD、MDA、ox-LDL were detected by enzyme or ELISA methods. In addition, (TC-HDL-c)/HDL-c and LDL-c/HDL-c were calculated. Results:Contrast with control group, LDL、LDL-c、(TC-HDL-c)/HDL-c、LDL-c/HDL-c、ox-LDL、MDA were markedly higher, while HDL-c and SOD were markedly lower in model group (P<0. 01). LDL、LDL-c、(TC-HDL-c)/HDL-c、 LDL-c/HDL-c、ox-LDL、MDA were markedly lower in ATV group than that in model group(P<0. 01); HDL-c and SOD were significantly higher in ATV group than that in model group(P<0. 01). Conclusion:Atorvastatin decreased blood lipid, inhibited the lipid peroxidation and the oxidative modification of LDL of rat serum. This result may be one of mechanisms in preventing atherosclerosis.
