<P>PROBLEM TO BE SOLVED: To provide a medical treatment material comprising crosslinkable polysaccharide derivative capable of being stably preserved even at room temperature. <P>SOLUTION: A proper amount of trehalose is added to the crosslinkable polysaccharide derivative having at least one active ester group capable of reacting with an active hydrogen-containing group introduced into a polysaccharide side chain and capable of forming a crosslinked substance due to the covalent bond of the active ester group with the active hydrogen-containing group by the contact with water under an alkaline condition. A mixed aqueous solution of the crosslinkable polysaccharide derivative and trehalose is freeze-dried to obtain the medial treatment material. <P>COPYRIGHT: (C)2008,JPO&INPIT |
