[Effect of extreme factors and adaptation to high-altitude conditions on peroxidation indices of serum lipids].

High and low temperatures, physical exercises and acute hypoxia are studied for their effect on indices of peroxide lipid oxidation in highly trained persons under alpine conditions (2100-5600 m). Temperature effects (-15 degrees C and +100 degrees C, for 30 minutes) as well as their combination with acute hypoxy cause an increase (by 10-30%) of malonic dialdehyde and a decrease (by 46-70%) of spontaneous chemoluminescence of blood serum in nonadapted people. Adaptation to alpine conditions in combination with physical exercises and low-caloric diet decreases shifts of these indices, considerably increasing the organism stability to the action of such extreme stress agents as high and low temperatures and acute hypoxy.

[Correction of the function of the sympathoadrenal system in the surgical and combined treatment of patients with cancer of the esophagus and stomach].

The study was concerned with the functional condition of the sympatho-adrenal system in 80 patients with cancer of the esophagus and proximal part of the stomach who had undergone surgery and received combined treatment, coupled with measures aimed at correcting the sympatho-adrenal system in some cases. Treatment with phenformin, decaris and S-methylmethionine was shown to produce a favorable effect on certain stages of catecholamine synthesis and metabolism as well as on immunologic indexes and hemodynamic stability.
