Abstract

Objectives : This study investigated the hypolipidemic and antioxidant effects of Curcuma radix using a rat model induced by poloxamer 407 injection. Methods : Serum lipid parameters and oxidative stress-associated biomarkers were determined. Additionally, hepatic cholesterol and triglyceride as well as lipid metabolism-associated gene expressions were observed in hepatic tissue. Results : 1. Curcuma radix ameliorated elevation of serum cholesterol, triglyceride, LDL-cholesterol, MDA, hepatic cholesterol level, and reduction of serum TAC, SOD, GSH, GSH-reductase level. 2. Curcuma radix augmented up-regulated ACAT gene expression. 3. Curcuma radix almost completely ameliorated down-regulated CYP-7A1 but up-regulated HMG-CoA gene expression. Conclusions : The hypolipidemic and antioxidant properties of Curcuma radix were evidenced. This study provides a scientific basis for the clinical application of Curcuma radix and development of hypolipidemics using this herb in the future.
