GAMMA-RAY-INDUCED DNA SINGLE STRAND BREAKS AND THEIR REPAIR IN V79 CELLS AND THYMOCYTES

Meng Ziqiang(Deparment of Environmental Sciences,Shanxi University)  
The gamma-ray-induded single strand breaks of DNAmolecules and their rejoining in cultured Chinese hamster lung fibroblasts(V79 cells)and thymocytes isolated freshly from mouse thymuses weredetected by KOhn's alkaline elution method.The percentage of DNA remainingon the filter membrane was inversely proportional to the radiation dosewithin the ranges of 1—30 Gy for V79 cells,and of 1—10 Gy for mousethymocytes.V79 cells were capable of rejoining the breaks and the rate ofrejoining was dependent on the radiation dose.The repair of damagedDNA could carry out in V79 cells cultured in TC199 medium with or withoutserum,but it could not be observed in mouse thymocytes cultured in RPMI1604 without serum or TC199 medium without serum.
