Since ancient times, ginseng has been used as one kind of treatment drug or tonic in China and even other eastern countries like Korea and Japan. Phar- macological active chemical ingredients and its extract of ginseng are a mixture of triterpenoid saponins, collectively called ginsenosides. Among them, ginsenoside Rgl is the most pharmacological active one. Based on prior experi- mental results and the understanding of alcoholic hepatitis, the major aim of this study is to investigate whether Rgl is beneficial in a rodent model mimic alcoholic hepatic injury associated with binge drinking and explore the under- lying possible mechanisms. Methods C57BL/6 mice were given oral consumption of 6 g · kg^-1 alcohol 1 h after treated with Rgl （ 10, 20 and 40 mg · kg^-1） or dexamethasone （ 1 mg · kg^-1） for 9 consecutive days. Biochemi- cal analyses were performed and liver fragments were processed for microscopy, immunohistochemistry and western blot analysis. Results According to our data, Rgl treatment significantly reversed the high mortality rate induced by alcohol consumption and also alleviated liver impairment as evidenced by the decrease of serum parameters. Meanwhile, histological and ultrastructural analysis of alcoholic groups showed hepatocellular impairment but re- stored in Rgl-treated groups. Overproductive inflammatory cytokines were also suppressed by Rgl in alcohol-intoxi- cated mouse livers. In addition, changes of GR related NF-KB pathway, including phospho-IKB-ot, were also mod- ulated to normal levels. Conclusion This study demonstrates that Rgl might promote GR mediating the repression of NF-KB and inhibit the inflammatory reactions in alcoholic hepatitis.展开更多
