[Adaptation to hyperthermia and changes in peripheral blood leukocytes in humans].

Heating humans up to rectal temperature 39.0-39.5 degrees C induces a heat stress and a physiological adaptation.

[Effect of a short-term moderate whole body hyperthermia of healthy humans on their peripheral lymphocytes].

A short (75-110 min) mild (39.5 degrees C) whole body hyperthermia of humans does not alter the absolute amount of peripheral lymphocytes immediately after heating, but significantly reduces their relative amount due to neutrophil increase. Body heating does not induce lymphocyte degeneration: their potential viability does not reduce.

[Aspects of healthy humans' response to hyperthermia].

Single-shot hyperthermia of healthy young men in climate chamber up to rectal temperature of 39.5 degrees C over 75-110 minutes revealed variable heat resistance. Individuals with prevalent sympathetic vegetative regulation were more resistant to overheating, if compared to those with prevalent parasympathetic one.

[Clinical-physiological aspects of normobaric hypoxic training effects on functional status of patients with neurocirculatory dystonia].

Profiles of external respiration and circulation, self-assessment of health, mental performance, sensory functions, and peripheral blood were studied in patients with neurocirculatory dystonia in the course of normobaric hypoxic training. The hypoxic training proved to successfully normalize arterial pressure, eliminate cardiac arrhythmias, and benefit general condition. Substantial strengthening of hypoxic resistance was stated along with an oxygen debt reduction during hypoxia, improvement of sensory coordination and mental performance, and activation of erythropoiesis.

[Methodological aspects and clinicophysiological substantiation of applying the hypoxic therapy].

The paper gives the methodical and clinicophysiological substantiation of the hypoxic therapy, a new nonmedicamentous method of body sanitation, raising its physiological reserves, prevention of pathological states, treatment and medical rehabilitation of patients based on breathing air with a reduced O2 partial pressure for the purposes. Health damaging and improving effects of hypoxic hypoxia, perspectives of this therapy from the standpoint of prevention and treatment of myocardial ischemia are discussed. Results of the fundamental studies unveiling the mechanisms of ischemic, reperfusion-induced disorders of myocardium and assessing possibilities of their blockage of the hypoxic therapy are considered.

[Immuno-physiological and hematological aspects of flight certification examination].

Revision of immunophysiological and hematological approaches to medical examination of flight personnel is the focus of this paper. Basing on literary data and results of their own investigations, the authors demonstrate the linkage between occupational impacts on flyers and alterations in the function of specific and non-specific body defense systems. Potential areas for updating flight certification examination procedure, i.

[Patterns of the changes in the indices of B-system immunity in acute psychoemotional stress].

Psychoemotional stress induces in healthy individuals increased serum Ig and C3 subunit of complement. Response of B immunity psychoemotional stress remains within the limits of basic functioning. State of B immunity in psychologic comfort condition insignificantly depends on individual psychology.

[The psychophysiological characteristics and correction of extreme states of an informational-semantic origin].

The article deals with the general characteristics of extreme states influence. The authors systematize the factors which may be considered as extreme ones. The article shows that the development of different extreme states frequently is predetermined by informative-semantic nature.

[Specific features of humoral immunity and nonspecific resistance in pilots].

Immune responses of the flying personnel to adverse flight effects were investigated. Altogether 134 pilots in the age of 22 to 42 years were examined. A significant decline of IgA, IgM, IgG, C3, alpha-antitrypsin, and R-proteins was found.

[Relations between the indicators of humoral immunity and psychological adaptation of pilots].

Peripheral blood serum A, M and G immunoglobulins were measured in 123 pilots, 22 to 42 years of age, distributed in groups as to the degree of frustrational tension (FT), related frustrational tension (RFT) and frustrational intolerance (FI). Inverse correlation was found between the indices of psychic adaptation (FT, RFT and FI) and the M immunoglobulin content. No evident correlation was traced between the levels of the circulating A and G immunoglobulins and the psychological peculiarities assessed in the pilots.
