Method : It was performed through measurement of effects Cirsium japonicum var. ussuriense extract (CJE) on NO production, NK cell cytotoxicity and cytokine gene expressions related with macrophage and NK cell activity. Result : 1. CJE did not show any direct cytotoxic effects on 7250, HT1080, Hep G2 and CT-26 cells. 2. CJE activated macrophages partially to product NO and up-regulated gene expressions for iNOS in RAW 264.7 cells. 3. CJE promoted cytotoxicity of NK cells against YAC-1 cells at higher concentration than 200 ㎍/㎖. 4. CJE up-regulated gene expressions for IL-1β, IL-2, iNOS, IFN-γ and TNF-α in mice splenocytes. 5. CJE inhibited lung tumor metastasis induced by CT-26 cell transplantation compared with the control group.
