| Popis: | In this report we have investigated that the amino acid is most actively metabolized in the tumor cells damaged by antitumor agents, and discussed imbalanced amino acid procedure to be combined with cancer chemotherapy. The concentrations of 24 free amino acids in medium and in cells were determined in HeLa cells treated with Adriamycin. The free amino acids that decreased in the medium but increased in cells were glutamine and arginine. From this result, we treated HeLa cells with Adriamycin in medium of glutamine-deficiency and obtained a marked cytocidal effect. It would be difficult to make tumor tissues of glutamine-depletion in the whole body. For clinical application, local administration such as intraarterial infusion of L-glutamine antagonists combined with antitumor agents is expected as a practical administration method.
