Hemoglobin, transferrin and total iron content in the blood serum in hyperoxia and during the protective action of urea]

A rise of hemoglobin concentration accompanied by an increase of the total iron in the blood serum of white mice was found under oxygen pressure of 4 atm for an hour (preconvulsive state) and 6 atm (convulsive state). Changes in correlations of hemoglobin fractions in the blood serum were detected in both stages of oxygen poisoning by disc-electrophoresis in 7.5% polyacrylamide gel. A rise of transferrin concentration under these conditions (hyperoxia) was observed. The deflections occurred were less pronounced following administration of urea to the animals before hyperbaric oxygenation.
