One purpose of the present invention is to provide a high molecular weight glucan having both properties low digestion rate and high digestibility. A high molecular weight glucan that has property digested slowly and contains almost no indigestible ingredients is produced by enzymatic reactions of (1) a specific concentration of branching enzyme and (2) 4-&#x3b1;-glucanotransferase and/or an exo-type amylase to a branched glucan used as a substrate.

High molecular weight glucan having low digestion rate

The present invention aims to provide antidementia agents which are free from the problem of side effects and are excellent in safety. The present invention also aims to provide agents for improving learning and memory which are useful for improvement of learning and memory and can be ingested continuously. The present invention provides antidementia agents and agents for improving learning and memory, each comprising a cyclic dipeptide with the 2,5-diketopiperazine structure as an active ingredient.

Learning and memory improver

A uric acid-lowering agent containing, as an active ingredient, a tyrosine-containing cyclic dipeptide selected from the group consisting of cyclotryptophanyltyrosine, cycloseryltyrosine, cycloprolyltyrosine, cyclotyrosylglycine, cyclotyrosyltyrosine, cyclophenylalanyltyrosine, cycloleucyltyrosine, cyclolysyltyrosine, cyclohistidyltyrosine, cycloalanyltyrosine, cycloglutamyltyrosine, cyclovalyltyrosine, cycloisoleucyltyrosine, cyclothreonyltyrosine, cycloaspartyltyrosine, cycloasparaginyltyrosine, cycloglutaminyltyrosine, cycloarginyltyrosine, cyclomethionyltyrosine, and cyclotyrosylcysteine, or a salt thereof. The uric acid-lowering agent of the present invention has an excellent action of lowering a uric acid level, and the uric acid-lowering agent is useful in, for example, prevention or treatment of hyperuricemia, gout or the like.

Uric acid-lowering agent

An impact-resistant film for a flat display panel, which is an impact-resistant film to be bonded to a front glass of a flat display panel main body and which comprises a first layer on the front glass side of the flat display panel, made of a transparent thermosetting resin, and a second layer on the viewer's side of the first layer, made of a transparent synthetic resin having a shear modulus larger than the first layer.

Impact-resistant film for flat display panel, and flat display panel

An impact-resistance film which is bondable to a front glass of a flat display panel main body that includes a first layer on the front glass side of the flat display panel that is made of a transparent synthetic resin having a shear modulus of from 1&#xd7;10Pa to 1&#xd7;10Pa. The film includes a second layer on the viewer's side of the first layer that is made of a transparent synthetic resin having a shear modulus of at least 1&#xd7;10Pa and includes a third layer on the viewer's side of the second layer that is made of a transparent synthetic resin having a shear modulus of at least 1&#xd7;10Pa and less than 1&#xd7;10Pa.
