Abstract

Human hepatoma cells hep G2 were irradiated with 3 Gy of γray 8 hours after primed with 0.05 Gy of γray， thereafter，cell survival and cell cycle were determined. The results indicated that both survival adaptive response and the enhanced ability to overcome G2/M arrest could be induced by preirradiation with low dose of γray. It is suggested that there is a certain correlation between the survival adaptive response and the enhanced ability to overcome cell cycle arrest.
