Abstract: front page image
(EN)Disclosed is a combination comprising (1) a polyaldehyde produced by introducing an aldehyde group into a side-chain glucose in β-1,3-glucan and (2) a polyamine produced by polymerizing a poly-L-lysine. The combination is useful as a material for a tissue-adhesive hydrogel which is less susceptible to the infection with a virus or the like, which has biodegradability/biocompatibility, which is highly safe, which is excellent in rate/strength of adhesion, and which can be used as a hemostatic agent or the like.
(FR)L'invention porte sur une combinaison comprenant (1) un polyaldéhyde obtenu par introduction d'un groupe aldéhyde dans un glucose de chaîne latérale dans du β-1,3-glycane et (2) une polyamine obtenue par polymérisation d'une poly-L-lysine. La combinaison est utile comme matière pour un hydrogel adhésif à un tissu qui est moins sujet à l'infection par un virus ou similaire, qui présente une biodégradabilité/biocompatibilité, qui est hautement sans danger, qui présente une excellente vitesse/résistance d'adhésion et qui peut être utilisé comme agent hémostatique ou similaire.
(JA) (1)β-1,3-グルカンの側鎖グルコースにアルデヒド基を導入したポリアルデヒド、および、(2)ポリ-L-リジンを高分子量化したポリアミン、を含む組合せ物を提供する。本発明の組合せ物は、ウイルスなどの感染症の危険性が低く、生分解性・生体適合性を有し、安全性が高く、接着速度・強度に優れた、止血剤等として利用できる組織接着性ハイドロゲルの材料として有用である。
