Effect of pulsed infrared laser radiation on DNA synthesis in tissues of intact rats and during strenuous physical exercise

The motor zone of the rat brain cortex is subjected to pulsed infrared (0.89 μ) laser radiation, which is found to stimulate DNA synthesis both in intact animals and after strenuous physical exercise (swimming). Preliminary laser irradiation exerts a stress-limiting effect on cells of the brain cortex and thymus but does not prevent swimminginduced reduction of³H-thymidine incorporation in nuclear DNA of muscles.

Seasonal differences in the development of heightened resistance of the isolated heart during adaptation to physical exercise

Substantial seasonal differences are found in the development of the cardioprotective effect of adaptation to physical exercise: in winter such adaptation results in an increase of the resistance of the isolated heart to the contracture and arrhythmogenic effects of ischemia and reperfusion, while in summer the anticontracture effect is absent and the antiarrythmic effect is significantly lowered.

Impact of twelve-day combined exposure to hypobaric hypoxia and physical exercise on structural and metabolic characteristics of skeletal muscle in rats

This study, in which rats were exposed on 12 successive days to hypoxia in combination with exercise on a treadmill, showed that a reduction in partial oxygen pressure leads to a decrease in the magnitude of the structural component of vascular resistance rather than to improvement in the system of oxygen utilization, and that such combined exposure may cause alterations in protein synthesis and result in early stimulation of capillary growth in muscles, as well as elicit differential changes of enzyme activity in different types of muscle fibers.

Reactivity of the conjunctival microcirculatory bed in students from various regions of the world as an indicator of adaptation of the organism

Microcirculatory vessels of the eyeball conjunctiva were examined during exercise in students from Asia, Africa, and Latin America. The reactivity of microvessels was found to be increased at the early stages of adaptation, which indicates a high-level compensatory potential of the organism. An appreciable reduction of microvessel reactivity after 1 to 2 years of university studies indicates a decrease of the compensatory potential in this period of adaptation. After 4–5 years of studies the reactivity of the microvessels is virtually the same in foreign and Russian students, this indicating the formation of a stable phase of adaptation.

Evaluation of tissue oxygen uptake using the anion gap parameter

The possibility of using the anion gap, a parameter characterizing the electrolyte balance, for an evaluation of tissue oxygen uptake is studied. A reliable reverse linear dependence is found between the anion gap at rest and oxygen uptake at the onset of the anaerobic threshold, which allows the anion gap to be used for evaluating the efficiency of respiration as a whole and the involvement of compensatory mechanisms in patients with respiratory disorders. The anion gap parameter makes it possible to determine the adequacy of tissue oxygen uptake and tolerance for physical strain without exercise testing. The dynamics of this parameter reflects the changes in tissue oxygen uptake and tolerance for physical strain in the course of treatment.
