AIM: To evaluate the therapeutic effects of Gamichunggantang (GCT) on hyperlipidemia through high cholesterol diet model. GCT is an Oriental herbal medication, which has been used for-the treatment of fatty liver, hyperlipidemia or alcoholic liver disease in Daejeon University Oriental Hospital, Korea since 1999. METHODS: Rats were fed with high cholesterol diet for 4 weeks and GCT was administrated for 2 weeks from 2 weeks later in expermental days. The levels of serum total cholesterol, HDL-cholesterol, and triglyceride were analyzed every week. Absolute and relative liver weight to body, and histophathological changes were determined at last day. And, lipid metabolism-related gene expressions (ACAT and DGAT) in liver tissue were analyzed by using RT-PCR. RESULTS:In GCT group, TG levels were reduced at 3 and 4 weeks after GCT administration (39.4%, P<0.05 and 36.3%,P<0.01 respectively). Total cholesterol levels also were reduced at 3 weeks (20.5%, P<0.05) and 4 weeks (35.86%, P<0.01) after GCT administration, but HDL-cholesterol levels were increased significantly (P<0.05) at 3 weeks(14.7%) and 4 weeks (25.5%) compared with hyperlipidemia-induced group without GCT. In the GCT treated group, liver weight was lower and lipid accumulation was decreased in histological finding. ACAT gene expression was suppressed compared with hyperlipidemia-induced group but not DGAT. CONCLUSION: GCT possesses preventive or therapeutic effects on diet-induced hypedipidemia by inhibiting the intestinal absorption and storage of exogenous and endogenous cholesterol.
