THE INFLUENCE OF OXYGEN ON THE FREQUENCY OF RADIATION-INDUCED CHROMOSOME ABERRATIONS IN OOCYTES OF DROSOPHILA MELANOGASTER (in German)
Abrahamson's results concerning the influence of oxygen on the frequency of x-ray induced structural changes (halftranslocations) in Drosophila oocytes were generally reproduced, especially the demonstration of a "reverse'' oxygen effect (under special experimental conditions protecting action of oxygen, sensitization by nitrogen). The added aberration frequencies of the 3rd and 4th day after the various treatments generally tended to decrease as compared with those of the first two days (dependence on state of maturity of the treated oocytes). Preirradiation treatment by nitrogen increased the aherration frequency significantly. Possible explanations of this effect are discussed. (auth)
