Patent ID: 7834065

Claim:
Medical-use two-part adhesive comprising: a first part comprised of aldehyde-groups-introduced glucan having a weight-average molecular weight in a range of 1000 to 200,000 and a second part comprised of amino-groups-containing polymer that is at least one selected from a group consisting of epsilon-poly-L-lysine, alpha-poly-L-lysine, chitosan oligomer and degraded chitosan and has a molecular weight in a range of 1000 to 20,000; wherein the aldehyde-groups-introduced glucan is produced by oxidation of glucan with periodic acid or periodate, as to have aldehyde groups at a density of 0.1 to 1.0 per anhydroglucose unit; and a mixture of the first and second parts, which are aqueous solution and/or powder, at a time of mixing them or with water has pH in a range of 5.0 to 8.0.
