[Role of the ceruloplasmin-transferrin system in regulating lipid peroxidation of the blood serum under various regimens of hyperbaric oxygenation].

Rats were treated with oxygen under the pressure of O-4 excessive atmospheres (ati) within 1 hr. Under the pressure of 2 ati content of ceruloplasmin was increased, while concentration of transferrin and content of lipid peroxidation products were decreased in blood serum. The level of ceruloplasmin and transferrin was unaltered, while lipid peroxidation was augmented under the pressure of 3-4 ati. At the same time, in vitro content of these proteins did not alter in blood serum, while concentration of the lipid peroxidation products was increased under the pressure of 2 ati. The system of ceruloplasmin-transferrin appears to be involved in regulation of lipid peroxidation in blood serum under conditions of hyperbaric oxygenation.
