Abstract: The present invention relates to a method for inhibiting myeloid-derived suppressor cells or treating cancer comprising administering a pharmaceutical composition containing decitabine or its pharmaceutically acceptable salt as an active ingredient. The decitabine suppresses creation of a cell population of myeloid-derived suppressor cells (MDSC) created in spleen and bone marrow in tumorigenic mice and induces apoptosis of the MDSC cell population. Therefore, the decitabine may be useful as agents for treating MDSC-related diseases and anticancer immunotherapy, or an anticancer supplement.

Abstract: The present invention is about a pharmaceutical composition, an oral preparation, and an injection preparation containing a G protein-coupled Receptor19 (GPCR19) agonist, specifically sodium taurodeoxycholate (HY2191) and its derivative, as an active ingredient for preventing or treating allergic skin diseases. The present invention is also about an external preparation and a cosmetic composition containing said pharmaceutical composition for preventing and improving allergic skin diseases. The said pharmaceutical composition shows an excellent efficacy in treating and improving allergic dermatitis compared with the steroid ointments or immunosuppressive ointments currently used. The said pharmaceutical composition reduces the level of serum IgE, which is a major factor causing allergic dermatitis, increases TH1 cytokine alleviating allergic dermatitis and reduces TH2 cytokine that exacerbates allergic dermatitis.

Abstract: The present invention relates to a use of a biological surfactant as an anti-inflammatory agent and a tissue preservative solution. More particularly, the present invention is directed to an anti-inflammatory agent and a tissue preservative solution comprising a biological surfactant which blocks a reaction of a proinflammatory factor with a receptor by emulsifying the proinflammatory factor.
