SunBangHwalMyungEum (SBH) has the effects of subduing swelling, resolving masses and alleviating pain in traditional oriental medicine. Recent studies showed that SunBangHwalMyungEum produced anti-cancer, anti-metastasis and immuno-modulatory effects. However there is lack of studies regarding the effects of SBH on the immunological activities. The present study was conducted to evaluate the effect of SBH on the regulatory mechanism of cytokines and nitric oxide (NO) in Raw 264.7 cells. Methods : After the treatment of SBH, cell viability was measured by MTT assay, NO production was monitored by measuring the nitrite content in culture medium. Inducible nitric oxide synthase (iNOS) was determined by immunoblot analysis, and levels of cytokine were analyzed by sandwich immunoassays. Results : Results provided evidence that SBH inhibited the production of NO, iNOS, $interleukin-1{eta}$ ($(IL-1{eta})$), IL-6, and the activation of phospholylation of inhibitor ${kappa}B{alpha}$ in Raw 264.7 cells activated with lipopolysaccharide. Conclusions : These findings suggest that SBH can produce anti-inflammatory effect, which may play a role in adjunctive therapy in Gram-negative bacterial infections.
