    摘要： The present liquid crystal composition is characterized by containing a dye of anthraquinone series represented by the following general formula (1) dissolved as a guest in a host liquid crystal: ##STR1## wherein R represents an alkyl group or a cycloalkyl group. The alkyl group or the cycloalkyl group of the dye of anthraquinone series includes those substituted by alkyl, hydroxyl, alkoxy, cycloalkyl, aryl, aryloxy, dialkylamino, or heterocyclic residue. Furthermore, the liquid crystal composition can contain two or more other kinds of the dye of anthraquinone series, or can be used in combination with other dyes. In the dye of anthraquinone series, the group --COOR at the 2-position and the group --CN at the 3-position are particularly important for realization of cyan color and a high S value.The dye of anthraquinone series is particularly effective for preparation of a black dye.The present liquid crystal display device is characterized by comprising a liquid crystal cell comprising two transparent juxtaposed substrate plates, transparent electrodes formed each on the opposite inner surfaces of the substrate plates, alignment films formed each on the opposite inner surfaces of the substrate plates to cover the transparent electrodes and align liquid crystal molecules, sealing members for keeping the two substrate plates at a predetermined distance, a liquid crystal composition containing the dye represented by the said general formula (1) being filled in the liquid crystal cell, and a light source being provided outside the liquid crystal cell.

    摘要： [Problem] To provide a new pharmacological action for high-molecular-weight polyphenols[Solution] To provide high-molecular-weight polyphenols extracted from fermented tea (e.g. oolong tea or black tea), which are high-molecular-weight polyphenols with a number average molecular weight ranging from 9,000 to 18,000, and containing in their partial structures a procyanidin structure of polymerized catechins and/or their gallates, and a structure of linkage between the B-rings of catechins and/or their gallates. These high-molecular-weight polyphenols have the functions of mitochondrial activation, suppression of increase in blood glucose, and suppression of weight gain. Therefore, they can be used as drugs for the treatment of mitochondrial disease, and also as drugs for the prevention and treatment of diabetes. They may also be added to health foods and beverages. The selected drawing shows changes in blood glucose level when the said high-molecular-weight polyphenols are given daily to diabetes model mice in specified doses.
