摘要： The present invention relates to an organic solvent-soluble mucopolysaccharide consisting of an ionic complex of at least one mucopolysaccharide (preferably heparin or heparin derivative) and a quaternary phosphonium, an antibacterial antithrombogenic composition comprising said organic solvent-soluble mucopolysaccharide and an organic polymer material, an antibacterial antithrombogenic composition comprising said organic solvent-soluble mucopolysaccharide and an antibacterial agent (preferably inorganic antibacterial agent such as silver zeolite), and to a medical material comprising said organic solvent-soluble mucopolysaccharide. The organic solvent-soluble mucopolysaccharide, and the antibacterial antithrombogenic composition and medical material containing the same, of the present invention, can easily impart antithrombogenicity and antibacterial property to a polymer to be a base material, which properties being maintained not only immediately after preparation of the material but also after long-term elution. Thus, the organic solvent-soluble mucopolysaccharide and antibacterial antithrombogenic material of the present invention show superior applicability as a material to impart antithrombogenicity and antibacterial ability to medical materials.

摘要： Since an inorganic and/or organic antibacterial agent and a hydrophilic substance are used in combination in this invention to produce an antibacterial composition, the intrinsic antibacterial activity of the inorganic or organic antibacterial agent is markedly increased, so that the antibacterial agent used even in a low concentration shows a high antibacterial activity. High antibacterial moldings can be obtained at a relatively low cost by laminating the antibacterial composition of the invention on an inorganic or organic substrate.

摘要： PROBLEM TO BE SOLVED: To provide an antibacterial property-imparting antithrombotic composition and medial instruments that are convenient, universal, and can retain the antithrombotic property for a long term. SOLUTION: An antibacterial property-imparting antithrombotic composition whose essential components are fat-soluble mucopolysaccharide made up of an ionic complex, one or more kinds of mucopolysaccharide and quaternary phosphonium, and an organic high polymer material. When it is extracted at 50 deg.C for 72 hours at a rate of 1 ml of physiological saline per 6 cm of surface area after the antibacterial property-imparting antithrombotic composition is applied to glass beads or formed into a film or coated to a molded body, the concentration of free phosphorus in the extracted liquid is 0.1 to 20 ppm.
