Abstract:
The present invention relates to a pharmaceutical composition, a food composition, and a cosmetic composition for anti-inflammation, containing 2,3-Bis[(2-hydroxyethyl)thio]-1,4-naphthoquinone as an active ingredient. The composition of the present invention fundamentally reduces the generation of TNF-α, PGE_2, and NO, which are inflammation-related factors, from the transcriptional stage, thereby exhibiting excellent anti-inflammatory effect. Further, the composition of the present invention can be safely applied to medicines, food, and cosmetics since it does not exhibit cytotoxicity in spite of treatment at high concentration. Accordingly, the composition of the present invention is expected to be significantly applied as an anti-inflammatory agent.

Abstract:
PURPOSE: A multi-layer film and a manufacturing method thereof is provided to form an acrylic copolymer resin layer and a photo catalyst layer on a film with a polylactic acid copolymer resin and a white inorganic particle, thereby increasing heat resistance and durability. CONSTITUTION: A polylactic acid copolymer resin layer is formed on a base material. The polylactic acid copolymer resin layer includes a polylactic acid copolymer resin which is made of L type polylactic acid and D type polylactic acid. The melting temperature of the polylactic acid copolymer resin is from 130°C to 180°C. An acrylic resin layer is formed on the polylactic acid copolymer resin layer. A photo catalyst layer is formed on the acrylic resin layer.
