Abstract: The present invention relates to ethylene-vinyl alcohol copolymer particles, comprising an ethylene-vinyl alcohol copolymer having an ethylene unit content of 1 mol % or more and less than 20 mol %, a viscosity-average polymerization degree of 200 to 5000, and a saponification degree of 80 to 99.99 mol %, wherein a crystallinity in water Cw (30° C.) at 30° C. and a crystallinity in water Cw (70° C.) at 70° C. as determined by pulse NMR satisfy formula (I). There is thus provided ethylene-vinyl alcohol copolymer particles having excellent solubility in water and excellent gas barrier performance.

Abstract: A method for treating liver dysfunction includes administering at least one member selected from a chitin oligosaccharide, a chitosan oligosaccharide and salts thereof, in an effective amount. As the chitin oligosaccharide, preferred is an oligosaccharide having a degree of polymerization of from 2 to 7. As the chitosan oligosaccharide, preferred is an oligosaccharide having a degree of polymerization of from 2 to 8. As the method for administration, it is preferred to add these oligosaccharides to foods, medicines or feeds, and to orally ingest them. However, when used as medicines, administration methods such as intravenous injection and muscular injection may be used.

Abstract: A method for treating and improving diabetes and liver dysfunction, can be obtained by administering at least one selected from a chitin oligosaccharide, a chitosan oligosaccharide and salts thereof, in an effective amount. As the chitin oligosaccharide, preferred is one having the degree of polymerization of from 2 to 7. As the chitosan oligosaccharide, preferred is one having the degree of polymerization of from 2 to 8. As the method for administration, it is preferred to add them to e.g. foods, medicines or feeds, and orally ingest them. However, when used as medicines, administration methods such as intravenous injection and muscular injection, may be used.
