모과(木瓜) 물추출물의 항염증 효능에 관한 실험적 연구

Abstract

Objectives: The purpose of this study was to investigate the effects of Chaenomelis Fructus Herba Water Extract(CF) on the production of inflammatory mediators in RAW 264.7 cell mouse macrophages stimulated with LPS. Methods: We have not examined effect of CF on the cell viability of RAW 264.7 cell until we investigated effects of CF on LPS-induced productions of NO,Ca and various cytokines in RAW 264.7 cell. And when p-value is below 0.05, it is judged to have the significant difference statistically(P<0.05). Results:1. CF increased the cell viability in the RAW 264.7 cell at the density of 25,50, 100 and 200 ㎍/㎖. 2. CF inhibited significantly increasing the production of NO in LPS-induced RAW 264.7 cell at the density of 25, 50, 100 and 200 ㎍/㎖. 3. CF inhibited significantly increasing the production of Intracellular Ca in LPS-induced RAW 264.7 cell at the density of 25, 50, 100 and 200 ㎍/㎖. 4. CF inhibited significantly the IL-2, IL-10, IL-12p70, TNF-α, GM-CSF, M-CSF,LIF and VEGF of the RAW 264.7 cell induced by LPS at the density of 25, 50,100 and 200 ㎍/㎖. 5. CF inhibited significantly the IL-4 at the density of 25, 50 ㎍/㎖, the IL-5,IL-15 and MIG at the density of 25, 50 and 200 ㎍/㎖ and IFN-γ at the density of 25, 100 ㎍/㎖ respectively in the RAW 264.7 cell increased by LPS. Conclusions: CF inhibited significantly increasing IL-2, IL-10, IL-12p70, TNF-a,GM-CSF, M-CSF, LIF, VEGF, NO and Ca in LPS-induced RAW 264.7 cell at the density of more than 25 ㎍/㎖ without causing the toxicity. These results signify that CF has antiinflammatory effect on controlling the over inflammatory reaction by the RAW 264.7 cell.
