다국어 초록 (Multilingual Abstract)

Objectives : The purpose of this study is to investigate the anti-inflammatory effect of Cheongsimyanggyeoksan(CYS) water extract in vitro and in vivo. Methods : To evaluate the anti-inflammatory effect of CYS, Raw 264.7 cells were pretreated with $3-300{\mu}g/m{\ell}$ of CYS for 1h, and then exposed to $1{\mu}g/m{\ell}$ of LPS. The cell viability was detected by MTT assay. Productions of nitric oxide(NO) and pro-inflammatory cytokines were measured in culture media. Protein levels of inducible nitric oxide synthase(iNOS) and Nuclear factor-${\kappa}$B($NF-{\kappa}B$) were determined by immunoblot analysis. The effect of CYS on acute inflammation in vivo was evaluated thorugh measurment of carrageenan-induced paw edema. Results : In vitro study, cell viability assay CYS treatment of $3-300{\mu}g/m{\ell}$ has no cytotoxicity in Raw 264.7 cells. LPS-induced NO production was significantly inhibited by pretreatment with $30-300{\mu}g/m{\ell}$ of CYS. Production of interleukin-6, -$1{\beta}$ and tumor necrosis factor-${\alpha}$ by LPS were significantly decreased by CYS pretreatment. CYS reduced LPS-mediated iNOS expression. Moreover, CYS significantly induced $I-{\kappa}B{\alpha}$ expression and reduced $NF-{\kappa}B$ expression. In vivo study, CYS significantly reduced the increases of paw swelling. Conclusions : These results suggest the clinical basis of CYS for the treatment of inflammatory diseases.
