Patent number: 5776758Abstract: The immunosuppressive drug of the present invention can suppress both delayed-type hypersensitivity and antibody production against specific antigens and graft tissues and induce immunological tolerance to them by several administrations, instead of long continuous administration.Cysteine protease, a secretory protein accumulated in the tissue of parasitic helminths, is extracted and purified. The cysteine protease is administered to a mammal and then tissue is implanted to the mammal.

Patent number: 5296254Abstract: To produce a filtering material for adsorptively capturing very fine particles such as fungus, pollen, virus, bacteria or the like at a high efficiency, an aqueous treatment solution is first prepared by dissolving porous apatite particles of 0.5 to 40% by weight, preferably, 0.5 to 30% by weight and a water soluble glucan of 0.5 to 15% by weight in water. A sheet-shaped raw material is then coated with the treatment solution with the aid of a rotating drum of which part is always dipped in the treatment solution, and thereafter, the sheet-shaped raw material having the treatment solution coated thereon is dried. Alternatively, an aqueous treatment solution prepared by dissolving only a water soluble glucan of 0.5 to 25% by weight in water may be substituted for the aforementioned aqueous treatment solution.Type: GrantFiled: June 8, 1992Date of Patent: March 22, 1994Assignee: Bestex Kabushiki-KaishaInventor: Sumiaki Tsuru

Patent number: 5164186Abstract: Disclosed is a drug-releaser comprising a porous body of biocompatibility filled with a medicine. Specifically, such porous body is made of baked calcium phosphate, 2-hydroxyethylmethacrylate, chitin, chitosan or their delivatives. Implantation or artery-injection of such drug-releaser causes a discernible curing effect on affected parts of the living body without causing any irritativeness. The steady release of the medicine from HAP particles to affected parts and the blockade of surrounding capillary vessels leading to such affected parts causes a remarkable tumor inhibitory effect.Type: GrantFiled: November 21, 1990Date of Patent: November 17, 1992Assignee: Kabushikigaisha ARS JapanInventors: Sumiaki Tsuru, Ichiro Masuno
