The present study was designed to examine the effect of tested preparation, WY-91 (consisting of ginseng extract, ganoderma extract and Royal jelly) on alcohol-induced unusual metabolism(such as blood glucose(BG), triBlyceride(TG), and blood urea nitrogen(BUN) level in blood) and nrperinlental liver injury($CCl_4$ and high fat diet) in mice. WY-91 lowered the level of blood glucose (BG),triglyceride(TG) and blood urea nitrogen(BUN) induced by alcohol in a dose-dependent manner. This preparation could protect hepatic function from a damages caused by high fat diet and $CCl_4$ administration(p.o.).
