RADIOACTIVE CHITOSAN COMPLEX HAVING AN IMPROVED STABILIZED GELATIN IN ADMINISTERING THEM TO THE BODY AND THEIR PREPARATION METHOD

摘要

The present invention relates to a radionuclide-chitosan complex solution and its preparation method, and more particularly to the radionuclide-chitosan complex solution having a viscosity of 300 ~ 2,400 cps, comprising an aqueous chitosan solution or a freeze-dried chitosan labeled with a radionuclide. The radionuclide-chitosan complex solution according to the present invention has a stable gelation state at a target region when injected into the body while maintaining a labeling yield of radioisotope to chitosan above 99 %. Side effects may be minimized and treatment efficiency may be increased when injected to a patient.
