We Previously reported that Polysaccharide Isolated from panax ginseng C. A. Meyer, stimulates murine splenocytes to proliferate and to be cytotoxic against a wide range of tumor cells in MHC non-restricted manner:) Therefore, we examined the cytokine mRNA expression induced by the ginseng polysaccharide in this paper. This study demonstrates that the ginseng polysaccharide stimulates Thl type cytosine expression such as IL-2 and IFNY, and macrophage type cytokine expression such as IL-lc and GM-CSF in a dose-dependent manner at different time: IL-2 mRNA was induced at 30 min, IL-la, GM-CSF mRNA at 3 hr, IFNY at 6 hr after the ginseng polysaccharide treatment. In contrast with these, Th2 type cytokine expression such as IL-4 and IL-5 was not induced. The generation of the ginseng polysaccharide-activated killer cells which was induced at the optimal doses of 50 pEyml was neutralized in the presence of anti-lL-2, anti-lFNy, anti-IL-l ${\alpha}$ antibodies, showing the importance of these cytokines produced by the ginseng polysaccharide. In flow cytometry analysis, the blastogenesis of IgM+ cells was induced on day 3 and the number of Thy 1.21 cells, CD4+ and CD8+ cells was increased on day 5. The ginseng polysaccharide also induced blastogenesis of T cells. In conclusion, the ginseng polysaccharide may have considerable antitumor immunotherapeutic modality by stimulating the cytokine production from Thl cells and macrophage and by proliferating lymphocytes.

To find the relation between exercise and cytokines, we examined the effect of the training intensity on the levels of cytokines, including interferon-gamma (IFN-γ), interlukine-4 (IL-4) and interlukine-4/interferon-gamma ratio (IL-4/IFN-γ ratio) in female Futsal players. Twelve well-trained female college Futsal players aged 19~22 participated in this study. The athletes completed 30-min of running at 60~65% maximal heart rate [moderate-intensity exercise], and 30-min of running at 75~80% maximal heart rate [high-intensity exercise]. peripheral blood samples were collected 24 h before and 24 h and 48 h after each of the exercise bouts. finding showed that The 30-min bout of moderate-intensity exercise induced a significant increase in IFN-γ (p=0.01) and significant decreases in IL-4 (p=0.001) and IL-4/IFN-γ ratio (p=0.003). And also, 30-min of running at 75~80% maximal heart rate induced increase in IFN-γ (p=0.07) and decreased in IL-4 (p=0.01) and IL-4/IFN-γ ratio (p=0.06) that these changes not significantly. In summary, exercise intensity can effect on the magnitude of changes in cytokines. It seems that moderate intensity exercise enhances cytokine pattern in female college Futsal players.

초기작에서 고향마을을 출발점으로 삼았듯이, 최근작에서는 제주도를 출발점으로 삼았다. 제주도는 억압되고, 유린된 곳이어서 구비서사시를 풍부하게 지녀 세계 전체에서 주목해야 할 사례의 한 표본이었다. 제주도에서 시작한 여정은 한국전체와 동아시아, 그리고 세계 전체로 동심원을 그리며 단계적으로 확대됐다.
