Abstract
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.
