英文摘要In this paper, we study the biological response induced by heavy ions irradiation of high dose, human peripheral blood lymphocytes are irradiated in vitro by the carbon ions of LET=35 keV/mu m, and the chromosome aberrations at absorbed doses of 0-20 Gy are analyzed by the calyculin A-induced premature chromosome condensation (PCC). The frequencies of PCC-rings at the stage of G2/M-phase increase steeply with radiation doses up to 20 Gy at a rate of 0.017 Gy(-1). The G2-PCC index remains more than 5% up to 15 Gy, and 3% after 20 Gy, this is high enough to score a substantial number of chromosome spreads without dose-rate effect. The results show that the calyculin A-induced PCC technique is suitable for analyzing the chromosome damage induced by carbon ions irradiation of high dose.
