Objectives : The purpose of this study is to investigate the anti-inflammatory effect of Geumeunwha-san(GEHS) water extract in vitro. Methods : To evaluate the anti-inflammatory effect of GEHS, Raw 264.7 cells were pretreated with 10-300㎍/㎖ of GEHS for 1hr, and then exposed to 1㎍/㎖ of LPS. MTT assay was used to detect the cell viability. Productions of pro-inflammatory cytokines and NO were measured in culture media. By using immunoblot analysis, protein levels of iNOS and NF-𝜅B were determined. Results : In vitro study, cell viability assay on GEHS treatment of 10-300㎍/㎖ has no cytotoxicity in Raw 264.7 cells. Pretreated 100, 300㎍/㎖ of GEHS had significantly inhibited LPS-induced NO production. And also pretreatment of 100, 300㎍/㎖ GEHS had significantly decreased production of interleukin-6, -1𝛽 and tumor necrosis factor-𝛼 in LPS-activated Raw 264.7 cells. In addition, GEHS reduced LPS-mediated iNOS expression. Moreover I-𝜅B𝛼 expression was significantly induced by GEHS and NF-𝜅B expression was reduced by GEHS. Conclusions : These results suggest the clinical basis of GEHS for the treatment of inflammatory diseases.
