- 摘要：
PROBLEM TO BE SOLVED: To provide an adhesive for a living tissue to control an adhesion time in response to the adhesive part of living tissue when the adhesive of a two-component system is used, in order to solve the following problem that the adhesion time is not controlled when an adhesive component concentration and a hardening component concentration are determined since an adhesive for the living tissue having in-vivo decomposing and absorbing property using a biopolymer is being developed but it is the adhesive of the two-component system including an adhesive component and a hardening component.
SOLUTION: An in-vivo decomposing and absorbing adhesive material for medical use of the two-component system is the adhesive, wherein an aqueous solution or a water-organic solvent mixture solution with a biodegradable high polymer and an inorganic salt dissolved therein or a phosphoric acid buffer solution with the biodegradable high polymer dissolved therein is defined as the adhesive component and also an organism-derived low-molecular weight derivative is defined as the hardening component. The kind and concentration of the inorganic salt or the concentration or pH of the phosphoric acid buffer solution are changed, so as to control the adhesion time.
