Objectives : This study was designed to investigate the effects of Injinchunggan-tang(Yinchenqinggan-tang) on the expression of inflammatory cytokine genes and proteins in kupffer cells. Materials and Methods : The mRNA expression level and protein secretion level were measured using quantitative RT-PCR and ELISA assay respectively in Injinchunggan-tang-treated and untreated kupffer cells after exposed to ethanol, acetaldehyde and lipopolysaccharide. Results : Injinchunggan-tang(Yinchenqinggan-tang) reduced mRNA expression level and protein secretion level of $TNF-{alpha},;TGF-{eta}1,;IL-1{eta},;IL-6,;IL-8$ that are induced by ethanol, acetaldehyde and lipopolysaccharide in kupffer cells and that mediate inflammation and fibrosis of liver. Conclusion : The result indicates that Injinchunggan-tang (Yinchenqinggan-tang) blocks alcohol-induced liver injury and protects liver by reducing production of inflammatory cytokines.
