Materials and Methods: The neutral version of the comet assay (single-cell gel electrophoresis) was used 24, 48, 72 hours after irradiation with 8 Gy gamma rays to assess interindividual differences in gamma rays-induced apoptosis in peripheral blood leucocytes between a panel of 30 normal individuals, and 30 breast cancer patients who hadn’t received radiotherapy or chemotherapy previously. Slides were stained with ethidium bromide and comets were assessed using visual and computer analysis. Results: In all incubation times, the baseline and radiation induced apoptosis values were higher in breast cancer patients compared to normal individuals which were significantly different (p }, URL = {http://ijrr.com/article-1-817-en.html}, eprint = {http://ijrr.com/article-1-817-en.pdf}, journal = {International Journal of Radiation Research}, doi = {}, year = {2012} }
