Author

Willis, R. J. and Kratzing, C. C.

Abstract

Cites a study conducted by researchers in Australia which examines the changes in levels of tissue nucleotides and glutathione after hyperbaric oxygen treatment. Destruction of tissue constituents by autoxidation; Factors that influenced the changes in glutathione and pyridine nucleotides; Detection of the small amounts of lipid peroxide in the erythrocytes of mice.

5. Transport of ascorbic acid in perfused rat lung

Author

Willis, R. J. and Kratzing, C. C.

Abstract

Rat lungs were perfused by recycling Krebs-bicarbonate solution in an apparatus which allowed negative pressure ventilation of the lungs. After addition of either reduced or oxidized ascorbic acid to the perfusion fluid serial samples were taken over 60 min and assayed for both reduced and oxidized ascorbic acid. At the end of perfusion, lungs were assayed for ascorbic acid. The results show that reduced ascorbic acid was taken up by the lung and concentrated in the tissue. No appreciable transport of oxidized ascorbic acid was measured.
