High radiosensitivity of fibroblast cells (AT5BIVA cells) from skin of Ataxia-telangiectasia (A-T) patients were studied by comparing with GM0639 (GM cells) from the skin of healthy adult. Using SOD (superoxide dismutase) and MDA (malondialdehyde) kit, the activity of SOD and content of MDA in AT and GM cells irradiated to 0, 1, 2, 3, 4Gy by ,60,Co γ-rays were detected respectively. The dose-response curves of SOD and MDA in AT and GM cells were established. In the irradiated cells, the SOD activity of AT cells were significantly lower than that of GM cells (,p,<,0.05), while the content of MDA of AT cells were significantly higher than that of GM cells (,p,<,0.05). In the two cell types, the activity of SOD had a negative correlation with the irradiation dose (,Y,=a-b,X,), whereas the content of MDA had a positive correlation with irradiation dose (,Y,=a+b,X,). The results show that the faculty of AT cells to cope with radiation-induced oxidative damage is significantly weaker than that of GM cells.
