Abstract |
Sister chromatid exchanges (SCEs) and structural chromosome aberrations (CAs) induced by cytostatic drug phopurinum in vivo and in vitro were studied in human lymphocytes. Phopurinum was found to cause a significant increase of CAs in lymphocytes of patients undergoing cytostatic therapy. Increased CA rates, however, declined rapidly after the cessation of treatment. This decline observed in vivo is in agreement with experimental results obtained in vitro, where it is found that the induction of SCEs and CAs occur only during the 1st cell cycle after pulse-treatment as G1 stage with phopurinum. Thus, phopurinum induced short-lived DNA damage both experimentally and in vivo.
