Abstract: The present invention relates to use for the prevention and/or alleviation and/or treatment of hypersensitivity immune disease, containing galactose and, more particularly, provides a pharmaceutical composition and a health functional food that comprise galactose for the prevention, amelioration and/or treatment of hypersensitivity immune disease such as atopic dermatitis.

Abstract: Disclosed are a polyester hollow fiber with excellent sound absorption and a method of manufacturing the same. The polyester hollow fiber may have a hollow ratio of about 27% to 35% compared to the cross-sectional area, and the value of the following equation (1) may be about 1.5 or greater, and the hollow in the cross-section preferably may be a three-lobed type and preferably may correspond to the following equation (1). P 4 ? ? ? A ( 1 ) In the above equation (1), A is the cross-sectional area (?m2) of the fiber, and P is the length (?m) around the cross-section of the fiber.

Abstract: The present invention relates to a novel brominated furanone derivative, a method for preparing the same, and a pharmaceutical composition containing the same as an active ingredient, wherein the novel brominated furanone derivative or a pharmaceutically acceptable 5 salt thereof according to the present invention exhibits a quorum sensing inhibitory activity of bacteria and also can effectively inhibit the formation of biofilm of bacteria, and thus can be used as a pharmaceutical composition containing the same as an active ingredient, thereby having an effect of being useful, 10 for example, for periodontal diseases such as gingivitis and periodontitis, oral diseases, and the like.

Abstract: The present invention relates to a method for whitening teeth. The method for whitening teeth according to the present invention can promote the whitening activity of a tooth whitening agent and increase the degree of permeation of the whitening agent into the teeth, thereby obtaining an excellent whitening effect. Therefore, an excellent whitening effect can be obtained despite the use of low-concentration peroxide, compared with the use of high-concentration peroxide.
