快中子诱发U251神经胶质瘤细胞的生物效应研究
A biological effectiveness study on U251 induced by fast neutrons
摘要
Abstract
Objective: U251 cells were exposed to fast neutrons of 14 MeV energy, and dose-response relationships were derived; Methods; cell samples were exposed to fast neutrons. Radiation doses were 1 Gy, 3 Gy, 5 Gy and 7 Gy respectively. The cell survival, apoptotic rate and proliferation were tested after irradiation; Result: with the growth of the radiation dose, cell survival was declined, and apoptotic rate was promoted; the speed of the cell proliferation, which was observed 48 h after irradiation, was slowed down obviously; Conclusion: compared to 晊 ray, fast neutrons have higher relative biological effectiveness.关键词
