Purpose: The purpose of this study was to investigate the anti-inflammatory effects of the water extract of Omisodokeum (OMSDE) on peritoneal macrophages, Methods: To verify the anti-inflammatory mechanism of OMSDE, the activation of nuclear $factor-{\kappa}B$ $(NF-{\kappa}B)$ and the phosphorylation of MAPK were examined. Results: The extract of OMSDE suppressed the production of LPS-induced nitric oxide (NO), tumor necrosis factor $(TNF)-{\alpha}$, interleukin $(IL)-1{\beta}$, IL-6 and IL-12 in the macrophages. OMSDE inhibited the degradation of inhibitory ${\kappa}B-{\alpha}$ $(I{\kappa}B-{\alpha})$ and it suppressed the activation of extracellular signal-regulated kinase (ERK 1/2) but didn't inhibit c-Jun N-terminal kinase (JNK) and p38, indicating that OMSDE may inhibit the pro-inflammatory cytokine production process by inhibiting the activation of $NF-{\kappa}B$ and ERK 1/2. Furthermore, OMSDE inhibited the production of interferon $(IFN)-{\beta}$ but didn't inhibit of $IFN-{\alpha}$ in the LPS-stimulated macrophages through the down-regulation of interferon regulatory factor (IRF)-1 and IRF-7. The Oral administration of OMSDE inhibited LPS-induced endotoxin shock and the production of $TNF-{\alpha}$ in serum but didn't inhibit of $IL-1{\beta}$ and IL-6. Conclusion: These results suggest that OMSDE may be effective in the prevention and treatment of inflammatory diseases.
