[Glutathione: dehydroascorbate-oxidoreductase activity in rat tissues].

Glutathione: dehydroascorbate reductase activity was studied in rat liver, heart, spleen, lungs as well as in Zajdela hepatoma. Correlation between the activities of glutathione reductase and glutathione: dehydroascorbate reductase was observed in all the tissues studied. Glutathione: dehydroascorbate reductase activity was higher in Zajdela hepatoma as compared with the rat liver. The role of glutathione: dehydroascorbate reductase in regulation of antioxidative activity and of cell division is discussed.
