PARTICULATE RADIOACTIVE NUCLEAR ENTRAPPED POLYMER, ITS MANUFACTURING PROCESS AND ITS KIT FOR MANUFACTURE

摘要

PURPOSE: A particulate radioactive nuclear species entrapped polymer is provided, which does not cause side effect by not coming out from gap between tissues different from solution type particulate radioactive nuclear, so can treat cystoma or arthritis effectively by even irradiation on treating part without precipitating of particle-shaped radioactive nuclear. CONSTITUTION: A particulate radioactive nuclear species entrapped polymer can be prepared by two methods. A first method is mixing particulate radioactive nuclear species with biodegradable polymer. A second method is: adding 1) biodegradable polymer solution, 2) particulate agent for radioactive nuclear species, 3) radioactive nuclear species solution; gaining particulate radioactive nuclear species; entrapping to biodegradable polymer.
