Abstract: Possibility of Pasteur effect in cancer cells in vivo was studied on mice with Ehrlich ascites carcinoma and rats with carcinoma of ovaries++. The experiments were run in two series. In the first series, all animals were saturated with oxygen through inhalation. In this series, part of the animals were given glucose subcutaneously. In the second series, all animals were given oxygen intraperitoneally and some of the animals with carcinoma of ovaries++ were given glucose subcutaneously. Values of inhibition of glycolytic activity in cancer cells under various experimental conditions were estimated through a calculated coefficient. Results of the experiment evidenced that inhalational saturation of animals with oxygen did not inhibit glycolysis of ascites cells in vivo while after intraperitoneal administration of oxygen, coefficient of inhibition of glycolytic activity in mice with Ehrlich ascites++ carcinoma after 45-65 min was 50-615, respectively. Experiments on rats showed that inhibition of glycolytic activity in rats can be revealed during simultaneous administration of oxygen intraperitoneally and of glucose subcutaneously. The authors reached the conclusion that under adequate supply of cancer cells with oxygen respiration can suppress glycolysis at the level of organism as well.
