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.

Abstract: The present invention relates to a complex of a protein comprising zinc oxide-binding peptides and zinc oxide nanoparticles, to the use thereof as a drug delivery carrier for manufacturing medicines, and to a vaccine composition and a contrast agent comprising the composite. The protein comprising zinc oxide-binding peptides significantly improves the in vivo availability of zinc oxide-binding peptides, and therefore the complex of the present invention can be used not only as a drug delivery carrier for in vivo drug delivery or intracellular drug delivery, but also for in vivo imaging or cell imaging. The complex can be used for producing separating agents for effectively separating biological materials, therapeutic agents for hyperthermia, etc., contrast agents for MRI, and beads applicable to biosensors.
