    摘要： This invention provides organic/inorganic composite biomaterials constituted by composites of hydroxyapatite and collagen and having an average fiber length of 60 μm or longer, and a process for producing the same in which the calcium ion and phosphate ion concentrations in the reaction vessel are optimized through regulation of the concentration of a starting material and the flow rate. The organic/inorganic composite biomaterials have mechanical strength and a biodegradation rate suitable for artificial bones through the introduction of crosslinking therein.

    摘要： The crosslinking agents and condensing agents that have been employed in biological adhesives and in treating medical devices such as cardiac valves are non-natural compounds synthesized artificially. Thus, they are not metabolized in vivo and exhibit toxicity to living bodies. These compounds are thus used only in a restricted amount and for limited purposes in the clinical sites. The present invention provides a biological low-molecular-weight derivative obtained by modifying carboxyl groups of a biological low-molecular-weight compound with N-hydroxysuccinimide, N-hydroxysulfosuccinimide, or a derivative thereof and a crosslinked high-molecular-weight product obtained by crosslinking various high-molecular-weight compounds with this derivative.

    摘要： Disclosed is a two-component, bio-degradable/absorbable adhesive medical material, which has a bonding component comprising a biodegradable polymer, and a hardening component comprising a low-molecular-weight derivative prepared by modifying a carboxyl group in a di- or tri-carboxylic acid of the citric acid cycle, with an electron-attracting group (one or a combination of two or more selected from the group consisting of a succinimidyl group, a sulfosuccinimidyl group, a maleimidyl group, a phthalimidyl group, an imidazolyl group, a nitrophenyl group and a tresyl group, and derivatives thereof). The present invention is intended to meet the need for developing a biological tissue adhesive having strong bonding force and low biological toxicity, in the situation where a conventional hemostatic material, blood-vessel embolizing material, sealant or aneurysm closing material has been liable to peel off from its applied site and has not been able to achieve sufficient hemostatic effect or sealing/closing strength in occluding a blood vessel, stopping bleeding, sealing air-leak or closing an aneurysm.
