[Effect of the extreme factors of antarctic regions on the composition of serum in polar explorers].

Extreme conditions of the Antarctic continent caused adaptive changes in the protein composition of human blood, expressed in the increased level of blood globulin fraction. The detected reduction in the Beta1A-gloubulins in the blood indicated a reduction of the infection immunity level. An increase of blood transferrin content of polar explorers served as a response of the organism to the influence of hypoxic hypoxia.
