Summary The investigation deals with the successful heterologous transplantation of the Mouse Crocker-Sarcoma on young rats, that were pretreated with the radioactive isotopes P32 and Au198. The growth tendency of the tumours varies according to the character of the radioactive isotope, the mode of administration and the interval between the injection of the radioactive substance and the heterotransplantation.

Summary The quantitative study of whole liver DNA and liver nuclei DNA at various ages, and the simultaneous study of oxygen uptake shows the following facts: (1) The rate of oxygen consumption to the fresh weight or to the DNA or to diploid chromosomes group is the same for the adult or the young aged 8 days. The values of oxygen consumption calculated for one cell or for one nucleus (taking notice of the fact that the mean level of liver nuclei DNA varies with the age) at 8 days is only the half of the adult value. Even at two months the value is 20% lower than in the adult. (2) In older animals there is a decrease of oxygen uptake which is more noticeable on a cellular scale than with the classical rate to fresh or dry weight. We affirm the fact that the diminution of the oxygen uptake of each cell is compensated by the increase of the number of cells.
