title: [Iron-containing proteins and the proteolytic activity in the blood serum in hyperbaric oxygenation and the protective action of urea].
abstract: The number and composition of ferro-containing proteins, the total number of iron, summary peroxidase activity and peptide-hydrolase activity have been determined under different hyperbaro-oxygenation (HBO) in blood serum. It has been established that under HBO the concentration of ferro-containing proteins increases, the fraction composition of serum and erythrocyte haemoglobin changes, the activity of acid peptide-hydrolases increases and the protamine-splitting peptide-hydrolase activity lowers. The administration of urea before HBO-experiments leads to the normalization of the most biochemical indicators of blood serum. The tests of oxygen intoxication depth assessment have been suggested.
