Abstract
This study attempted to increase the boron uptake of human head and neck carcinoma SAS cells for BNCT by using a gamma dose of 0.1 Gy for combined treatment. Intracellular boron concentrations in 25 μg B/mL medium of BPA treated and BPA combined gamma-irradiation treated SAS cells were 73.8±1.73 and 95.15±1.36 ppm, respectively. After neutron irradiation, the G2/M-phase cell populations of untreated, BPA treated and BPA combined gamma-irradiation treated SAS cells were 19.31±1.71%, 52.47±2.25% and 59.19±2.63%, respectively. Experimental results indicate that the low dose gamma radiation with combination BPA treatment has the highest killing rate after neutron irradiation. Capable of significantly increasing the G2/M arrest after neutron irradiation, the combined treatment of a low dose of gamma irradiation with 25 μg B/mL medium of BPA also provided a higher killing effect for BNCT.
