    Abstract: A drug-introduced photo-crosslinked hyaluronic acid derived gel which is a photo-crosslinked hyaluronic acid gel into which a drug is introduced through a covalent bond, and has characteristics that are capable of extruding from an injection device. The drug-introduced photo-cross-linked hyaluronic acid derived gel is capable of extruding, for example, by an injection needle of 20 to 25 gauge with a pressure of 0.5 to 5 kg/cm2.

    Abstract: A polysaccharide derivative having a high solubility in an aqueous solvent is produced. The production method of the present invention uses a compound shown by the general formula (1) as a condensing agent and allows a polysaccharide having a carboxyl group to react with an an organic compound having a functional group capable of condensing with the carboxyl group to prepare the polysaccharide derivative: R1 and R2 independently represent a substituent selected among alkyl groups of 1 to 4 carbon atoms and aryl groups of 6 to 8 carbon atoms; Z−represents a counter anion; and E+represents an organic group shown as: R3, R4, and R5 independently represent an organic group having at least one carbon atom directly bound to a quaternary nitrogen atom and any two or all of R3, R4, and R5 may link together to form a cyclic structure.
