[Critical conditions as a logical and appropriate series of events in iron methabolism disorders (the summary of experimental studies)].

It is revealed that in all models of critical conditions will activate the free-radical oxidation, decreasing the total antioxidant activity, the concentration of transferrin decreases in the serum of the blood, increase of the concentration of ferritin, the theological properties of the blood are violated and the signs of endothelial dysfunction are identified. Pre-entered deferoxamine in the dose of 80 mg/kg reduced the intensity of free-radical oxidation processes, restoring the antioxidant potential, concentration of the transferrin, and a lower level of ferritin, contributed to the normalization of blood theological properties and a reduction of the extent endothelium destruction as a result of the reduction Fe2+ concentration in blood serum.
