| Research Abstract |
Ethylene vinyl acetate copolymer is a convenient vehicle capable of sustained drug release. BrdU,thymidine analogue, is incorporated into S-phase cells and enhances susceptibility of cells to irradiation and UV.However, BrdU was not used generally because of its systemic toxicity. We developed BrdU polymer capable of sustained BrdU release. We applied this polymer to subcutaveous rat 9L glioma and examind radiosensitizing effect of BrdU polymer. However, we did not find difference in tumor size between rats reated by irradiation plus polymer and those treated only by irradiation. The reason why BrdU polymer did not show radiosensitizing effect glioma in vivo is under investigation.
