In the present invention, a uronic acid residue (uronic acid represents iduronic acid or glucuronic acid; hereinafter the same applies to uronic acid) and a glucosamine residue are combined with an α1,4-glycosidic bond or a β1,4-glycosidic bond. Or an oligosaccharide of 3 to 16 sugars or a salt thereof having a structure in which a uronic acid residue and a glucosamine residue are alternately and repeatedly bonded by α1,4-glycosidic bonds or β1,4-glycosidic bonds, , At least one hydroxyl group of uronic acid residue and glucosamine residue may be sulfated, alkylated, acylated or aminated, and the amino group at the 2-position of at least one glucosamine residue is sulfated, alkylated An object of the present invention is to provide an HGF production-promoting drug containing an oligosaccharide or a salt thereof which may be acylated or acylated as an active ingredient To. The HGF production-promoting agent of the present invention is useful for promoting the healing of disorders of living tissues, organs and the like. [Selection figure] None |
