Hypercholesterolemia is associated with many pathological states such as fat deposit in the tendon and skin, hepatomegaly, pancreatitis and heart attack. The present study was focused on the effect of Korean red ginseng water extract (RGWE) on the recovery of hepatic function that was deteriorated in high-cholesterol diet fed mice. Mice were divided into 6 groups ; normal diet group (AIN-2WK), 4 week-high-cholesterol diet group (CHOL-4WK), 2 week-high-cholesterol + 2 week-normal diet group (CHOL-2WK), 2 week-high-cholesterol + 2 week-normal diet + RGWE treated group (R100, R300, R500). RGWE treated group received normal diet and RGWE at daily doses of 100, 300, 500 mg/kg b.w. for 2 weeks after the 2 weeks feeding of high-cholesterol diet. The results are as follows : 1. The hepatic weight and total hepatic lipid weight were markedly lower in RGWE treated group than those in the CHOL-4WK or CHOL-2WK group, indicating that ginseng inhibited hepatic hypertrophy. 2. Total hepatic cholesterol and HDL-cholesterol in normal diet conversion group (CHOL-2WK) were significantly reduced compared with the high cholesterol group (CHOL-4WK). The lowering effect was significantly reinforced by RGWE administration. 3. Hepatic triglyceride level of CHOL-4WK group was markedly lower than that of the normal group (AIN-2WK). However, the level was significantly increased in CHOL-2WK and RGWE treated group. The result indicated that ginseng administration and diet conversion exert normalizing effects of hepatic function. 4. The lipid peroxide levels in RGWE treated groups were markedly lower than CHOL-2WK group. These results suggest that Korean red ginseng water extract can be useful as a dietary supplement for the treatment of obesity or hypercholesterolemia by improving lipid metabolism and hepatic function.
