Medical-use two-part adhesive comprising; first part comprised of an aqueous solution or a powder of aldehyde-groups-introduced alpha-glucan; and second part comprised of an aqueous solution or a powder of amino-groups-containing polymer that is formed of a polymer chain of amino-group-containing units and has a molecular weight in a range of 1000 to 20,000; as well as medical-use hydrogel resin obtained by curing the adhesive. A mixture of the first and second parts, at a time of mixing them to form the hydrogel has pH in a range of 5.0 to 8.0. In a preferred embodiment, the amino-groups-containing polymer is epsilon-poly-L-lysine produced by microorganism or by enzyme.

Medical-use two part reactive adhesive and medical-use resin having self-degradation property

An adhesive composition for surgical use including an &agr;-cyanoacrylate adhesive composition with a polymer characteristic for biodegrading and bioabsorbing the adhesive into the body of a living organism. It is preferred that the polymer is a co-polymer of DL-lactic acid and &egr;-caprolactone or a co-polymer of DL-lactic acid, ethylene glycol and &egr;-caprolactone, or a co-polymer of ethylene glycol and &egr;-caprolactone.
