Objectives : The purpose of this study was to evaluate the anti-Inflammatory effect of Hwadokdan(HDD) extracted with water. Methods : We pretreated LPS-activated Raw 264.7 cell with HDD and anti-inflammatory effect of HDD is investigated by measuring NO production, relative iNOS, and TNF-α, IL-6, IL-1β, PGE2 productions level, p-IκBα, IκBα, NFκB. Results : HDD reduced NO production and iNOS protein, TNF-α, IL-6 level at concentration of 100㎍/㎖ and 300㎍/㎖ in LPS-activated Raw 264.7 cell significantly. There wasn't a significant cytotoxicity in MTT assay. And HDD reduced IL-1β level at concentration of 300㎍/㎖ in LPS-activated Raw 264.7 cell significantly. HDD reduced p-IκBα and NFκB protein level at concentration of 300㎍/㎖ in LPS-activated Raw 264.7 cell significantly. And HDD enhanced IκBα protein level at concentration of 100㎍/㎖ and 300㎍/㎖ in LPS-activated Raw 264.7 cell significantly. Conclusions : These suggests that HDD can be used as a therapeutic drug for various inflammatory diseases.
