This study was designed to elucidate whether combination with Korean red ginseng and Morus alba L. (MPM), traditional treatment for diabetes, ameliorates on high fructose-induced steatohepatitis and vascular inflammation. 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 diet alone for 8 weeks, with supplementation with MPM or rosiglitazone, peroxisome proliferators-activated receptor gamma (PPARr)agonist, occurring during the final 6 weeks. Treatment with MPM significantly prevented the increase in c-reactive protein (CRP) levels in the high fructose group. MPM suppressed high fructose diet-induced vascular inflammation marker expression such as intracellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and E-selectin. MPM also reduced intima/media thickness of thoracic aorta. Histologic observation and oil red O staining demonstrated hepatic tissue damage and lipid accumulation were severe in high fructose group. Treatment with MPM ameliorated hepatic tissue morphology with minimized steatosis. In addition, MPM attenuated hepatitis by inhibition of monocyte chemoattractant protein-1 (MCP-1) expression. MPM-fed group showed lower serum GOT and GPT levels comparing with high fructose group. MPM and rosiglitazone (positive control) significantly decreased the size of epididymal adipocytes. Taken together, the administration of MPM inhibited high fructose-induced steatohepatitis and vascular inflammation. These results suggested that MPM is useful in the prevention or treatment of metabolic syndrome-related disorders such as fatty acid metabolism and vascular homeostasis.
