In accordance with the present invention, a peroral preparation, food and drink, feed, food additive or feed additive for prevention or treatment of atopic dermatitis comprising hydroxyproline or N-acylated derivative of hydroxyproline or a salt thereof is able to be provided and, particularly, said peroral preparation, food and drink, feed, food additive or feed additive comprising 0.1 to 90% by weight of hydroxyproline or N-acylated derivative of hydroxyproline or a salt thereof is able to be provided.
摘要:
An illumination control system comprises a rotation detecting section, an abnormality determination section, and a filter removing section. The rotation detecting section detects the rotational driving of a filter which is located on a path of illumination light emitted from a light source, which irradiates color light rays having different wavelengths to an object, and which is driven by a rotational driver. The abnormality determination section determines whether status of filter rotation is normal or abnormal based on the detected rotation of the filter by the rotation detecting section. The filter removing section removes the filter from the path of the illumination light when the abnormality determination section determines that the status of filter rotation is abnormal.
摘要:
A composition and method for stabilizing proanthocyanidin, especially for preventing, for example, its discoloration by oxidative polymerization. The method utilizes (and the composition contains) proanthocyanidin, and an amino acid having a hydroxyl group or a dipeptide containing said amino acid. Also shown is a drink, food, cosmetic or medicament which contains the composition.
摘要:
The present invention relates to a process for purifying dimeric to pentameric proanthocyanidin oligomers which comprises extracting the proanthocyanidin oligomers from raw materials containing the proanthocyanidin oligomers or crude purification products therefrom by solid-liquid extraction using methyl acetate as a liquid phase; a process for purifying dimeric to pentameric proanthocyanidin oligomers which comprises pretreating with an enzyme for hydrolysis raw materials containing the proanthocyanidin oligomers, crude purification products therefrom, or a solution containing one of these; and a process for purifying dimeric to pentameric proanthocyanidin oligomers with a uniform polymerization degree which comprises separating and purifying the proanthocyanidin oligomers by polymerization degree from raw materials containing the proanthocyanidin oligomers or crude purification products there from by normal phase silica gel liquid chromatography using as a mobile phase a single solvent or a mixed solvent of two or more solvents selected from the group consisting of an ester solvent, a ketone solvent, a hydrocarbon solvent, an ether solvent and an alcohol solvent.
摘要:
The present invention provides a hair-growing agent comprising, as an active ingredient, a phosphatidic acid represented by formula (I): (wherein R1 represents alkyl, alkenyl, alkanoyl or alkenoyl; and when R1 represents alkyl or alkenyl, R2 represents alkyl, alkenyl, alkanoyl or alkenoyl, and when R1 represents alkanoyl or alkenoyl, R2 represents alkyl or alkenyl).
