[Ascorbic, keto and hydroxy acid metabolism in the cell nuclei of certain tumors].
The authors report the results of studies on the content of ascorbic acid, pyruvic acid and the activity of malate dehydrogenase decarboxylizing (MDHD) in cell nuclei of uterine fibromyoma, glandular hyperplasia of the endometrium with epithelial proliferation, common ovarian cyst and solid cancer. It was shown that due to the glycolysis inhibited respiration an oxidated form of ascorbic acid is absent in every case, whereas the MDHD activity is not manifested. The amount of a reduced form of ascorbic and pyruvic acid in benign tumors is at the control level, but in malignant growth these indices are markedly increased.
