  • Title: [Comparison of the radiosensitivity of chromosomes during the S and G2 periods in regenerating rat liver cells].
    Author: Polishchuk AM, Aksenovich TI, Mamaeva OA.
    Journal: Genetika; 1976; 12(4):35-40. PubMed ID: 955412.
    Abstract:
    Radiosensitivity of chromosomes at S and G2 periods was studied by means of autoradiography technique in cells or regenerating liver of rats treated with X-rays at the doses of 150 and 300 r. The experiments were made so that the interval between irradiation and mitosis in S and G2 cells was equal. The results have shown that under the experimental conditions there are significant differences in the yield of chromosome aberrations between the labelled and intact cells. This withnesses for the existence of differences in radiosensitivity of chromosomes at different periods of mitotic cycle.
