Objectives : The purpose of this study was to evaluate the anti-inflammatory effect of Tanghwajitongsan(THJTS) through inhibition of NF-κB and MAPK. Methods : We evaluated cell survival rate by MTT assay, NO production by nitrite content in the culture medium. We quantified TNF-α, IL-1β, IL-6 and PGE₂ of the cultured supernatant by ELISA. And we evaluated the effect of THJTS on protein expression of NF-κB, MAPK, iNOS and COX-2 by Western blot analysis. THJTS ameliorates LPS-activated alterations in protein expression of NF-κB, p-38, iNOS and COX-2 and production of NO, pro-inflammatory cytokines and PGE₂. Also, THJTS ameliorates LOX, PGN and FLA-activated alterations in protein expression of NO, iNOS. THJTS ameliorates only PGN-activated alterations in protein expression of COX-2. Results : THJTS ameliorates LPS-activated alterations in protein expression of NF-κB, p-38, iNOS and COX-2 and production of NO, pro-inflammatory cytokines and PGE₂. Also, THJTS ameliorates LOX, PGN and FLA-activated alterations in protein expression of NO, iNOS. THJTS ameliorates only PGN-activated alterations in protein expression of COX-2. Conclusions : This study can provide scientific evidence for the anti-inflammatory effects and underlying mechanisms of THJTS.
