20090003013 | OVERSPEED PREVENTION STRUCTURE USING PLASTIC OPTICAL FIBER - An overspeed prevention structure is disclosed herein. The overspeed prevention structure according to the present invention comprises a structural body having a curved convex upper surface; an external light source; and a plastic optical fiber embedded in the structural body and connected electrically to the external light source so as to emit the light outside the structural body. | 01-01-2009 |
20100190729 | Composition for treating atopic dermatitis comprising hirsutanonol or oregonin as an active ingredient - The present invention relates to a composition for treating atopic dermatitis comprising hirsutanonol as an active ingredient. Hirsutanonol or oregonin as the active ingredient of the present composition decreases the number of eosinophil increased in atopic dermatitis and regulates expression amounts of immune regulatory cytokines, IL-4, IL-5, IL-10 and IL-13 associated with atopic dermatitis. In addition, hirsutanonol and oregonin increase MBD (mouse beta-defensin)-1, MBD-2 and MBD-3 expression and decrease COX-2 and iNOS expression in mouse animal model of atopic dermatitis. Hirsutanonol and oregonin as the active ingredient of the present composition could be effectively used in drugs, cosmetics and foods for treating atopic dermatitis. | 07-29-2010 |
20100190862 | Composition for treating atopic dermatitis comprising hirsutenone as an active ingredient - The present invention relates to a composition for treating atopic dermatitis comprising hirsutenone as an active ingredient. Hirsutenone as the active ingredient of the present composition decreases the number of eosinophil and the level of IgE increased in atopic dermatitis and remarkably reduces expression amounts of immune regulatory cytokine (e.g., IL-4, IL-5 and IL-13) associated with atopic dermatitis. In addition, hirsutenone decreases COX-2 and iNOS expression. Hirsutenone as the active ingredient of the present composition could be effectively used in drugs, cosmetics and foods for treating atopic dermatitis or relieving a symptom of atopic dermatitis. | 07-29-2010 |
