[Combined effect of hyperglycemia and chemo- and radiation action on the status of metabolic processes in certain experimental sarcomas in rats].
A number of metabolic parametres were studied in subcellular fractions of rat sarcoma 45, M-1 and carcinosarcoma Worker 256. Administration of high doses of glucose amplified some effects of chemotherapeutic drugs and X-ray therapy, which were manifested as follows: a decrease in glycolysis rate, alteration in the rate of redox reactions, shifts in the ratio between glycolysis and biological oxidation in mitochondria. These alterations were determined by the type of sarcoma, by sequence of operations in the procedure and by cytostatic used. The most effective procedure proved to be simultaneous administration of drugs and X-ray therapy followed by hyperglycemia. Distinct inhibition of glycolysis defected under these conditions may contribute to inhibition of energy metabolism during the sarcoma growth and regression.
