AGENT FOR AMELIORATING TYPE-2 DIABETES, AND FOOD OR BEVERAGE CONTAINING SAME
Several attempts to utilize components derived from natural products have been tried for the purpose of ameliorating type-2 diabetes. However, no effective technique that can achieve a satisfactory effect has not been proposed yet. Then, provided is a technique for ameliorating type-2 diabetes satisfactorily by using a natural-product-derived component that has few adverse side effects. It is found that a wax mixture extracted and isolated from Kaoliang has such excellent physiological activities that the wax mixture can reduce the blood glucose level and the plasma insulin level more effectively, increase the adiponectin level, and reduce the level of resistin, which is one of adipocytokines that have been believed to induce insulin resistance, in a mouse suffering from type-2 diabetes, compared with a wax that is isolated from a plant other than Kaoliang or an animal or a higher saturated aliphatic alcohol (policosanol) which have been tried to utilize so far.
A display sheet comprising: a base; front-side and back-side layers of a synthetic resin composition which have been formed respectively on the front and back sides of the base; and an ink layer formed by ink-jet printing on the front-side layer of a synthetic resin composition. The base comprises a canvas having recesses and protrusions on the front and back sides. The surface of the front-side layer of a synthetic resin composition has been formed as a rugged surface composed of protrudent parts and recessed parts attributable to the recesses and protrusions of the base surface. The ink layer has been formed from a fine ink, which covers the protrudent parts and has infiltrated into the recessed parts. The display sheet further includes a pressure-sensitive adhesive layer on the back-side layer of a synthetic resin composition and a release paper superposed on the surface of the pressure-sensitive adhesive layer. The release paper comprises crepe paper which has undergone crepe processing and has a tensile elongation at break in the range of 5-50%. This display sheet is less apt to suffer a decrease in display/decoration perceptibility caused by the wear of the printed surface, even when used, without forming a protective layer thereon, on an outdoor floor surface frequently walked.
