[Regulation effect of curcumin on blood lipids and antioxidation in hyperlipidemia rats]

The regulation effects of curcumin on lowering blood lipids and antioxidation were studied in the hyperlipoidemia model Wistar rats fed with high fat diet for 4 weeks. The hyperlipoidemia model rats were then separated into four groups: normal diet group, normal diet + curcumin (5 g/kg) group, high-fat diet group and high-fat diet + curcumin group. The rats were fed with experimental diets for another 4 weeks respectively. The results indicated that curcumin decreased the serum levels of cholesterol and triglyceride and increased the serum level of apolipoprotein A. Curcumin decreased TBA value and improved total antioxidation capability. The activities of SOD and GSH-PX in liver were enhanced. After taking normal diet for four weeks, the blood fat and cholesterol levels of the hyperlipoidemia rats recovered. But in the normal diet + curcumin group, the same results could be found in two weeks.
