摘　　要：利用蒙卡程序MCNP/4B(Monte Carlo N-particle transportcode/4B)设计了C6细胞辐照实验的铀氢锆堆中子源。建立了细胞培养、孵育、L-BPA(L-boron phenylalanine)给药、细胞内宏观硼浓度测定及辐照实验方法,观察了BNCT(Boron neutron capture therapy)辐照实验对体外C6胶质瘤细胞的放射生物学效应,研究了C6细胞BNCT辐照效应与照射剂量之间的关系。试验结果表明,在同等吸收剂量下,BNCT对C6细胞的杀伤作用远远大于γ射线。A neutron source of UHZr reactor for C6 glioma cells irradiation is designed by MCNP/4B code. Methods for cell culture, incubation, L-BPA administration, boron concentration measurement and the irradiation experiment are described. Radiobiological effects of C6 glioma cells in vitro, which are induced by BNCT, and the relations between the biological effect and the irradiation dose are studied. The results demonstrate that the cytocidal effect of the BNCT method is much more remarkable than that of gamma radiotherapy at the same absorbed dose.
