Objectives : Korean red ginseng and Morus alba L. are used as a traditional treatment for diabetes. This study was designed to elucidate whether combination with Korean red ginseng and Morus alba L. (MPM) ameliorates metabolic syndrome in fructose-fed rats. Methods : Animals were divided into four groups; Control receiving tap water, fructose-fed, rosiglitazone-treated fructose-fed rats, and MPM-treated fructose-fed rats both receiving supplemented with 60% fructose (n=10). The MPM or rosiglitazone groups initially received a high-fructose (HF) diet alone for 8 weeks, with supplementation with MPM or rosiglitazone occurring during the final 6 weeks. Results : MPM and rosiglitazone, synthetic $PPAR{\gamma}$ agonist, treatment significantly prevented the increase in fasting serum glucose, leptin, triglyceride, and low density lipoprotein in the HF group when comparing with the control group. MPM and rosiglitazone also led to an increase in high density lipoprotein level in the HF group. The administration of MPM and rosiglitazone prevented the development of the metabolic disturbances such as impaired glucose tolerance, and blood pressure. MPM suppressed increased expressions of endothelin-1 (ET-1) in HF rat aorta. In addition, MPM significantly increased IR-${\beta}$ and PPAR-${\gamma}$ expression in muscle. Conclusions : Based on these results, we suggest that the administration of MPM improves metabolic syndrome through the alteration in lipid profiles and suppression of insulin resistant and blood pressure.
