After Euglena cells were irradiated with a gamma dose of 1 x 10/sup 5/ r the cells were cultured for times of 1, 6, 12, and 24 hours in a culture medium containing 0.1 mu c P/sup 32/ per ml. Cell fractionation was carried out by a modified Schmidt and Thannhauser's method. Incorporation of P/sup 32/ was observed on each of acid soluble, lipid, DNA RNA, and phosphoproteid fractions obtained by this method. From the experiments, the following tentative conclusions were obtained; incorporation of P/sup 32/ into nucleic acids and other phosphorus containing substances is inhibited by gamma irradiation. The results show gamma -irradiation markedly inhibits an increase of the cell population. (auth)
