Objective : Ssanggang-tang(SGT) is noted as an effective method to treat hyperlipidemia in China. The main purpose of this study was analysis of the effects of Ssanggang-tang(SGT) on rats induced with caused hyperlipidemia. Methods : We observed 3 experimental groups: normal, control, and SGT. Rats were provided a normal diet in the normal group, and the other groups were provided a hyperlipidemic diet to induce hyperlipidemia. After 2 weeks, SGT was treated in the SGT group. For 6 weeks, values related to hyperlipidemia were observed in the 3 experimental groups. Results : SGT decreased some values related to hyperlipidemia like total cholesterol, low density lipoprotein cholesterol(LDL cholesterol), triglyceride, acetocoenzyme A acetyltransferase(ACAT), and 3-hydroxy-3-methylglutaryl coenzyme A reductase(HMG-CoA reductase). However, it showed no effect on weight change or high density lipoprotein cholesterol(HDL cholesterol). Conclusion : These results suggest that SGT might be effective in treatment and prevention of hyperlipidemia.
