[The influence of non-invasive electrical stimulation of the spinal cord on the locomotor function of patients presenting with movement disorders of central genesis].

Aim: The objective of the present study was to evaluate the influence of non-invasive (transcutaneous) electrical spinal cord stimulation on the locomotor function of the patients suffering from movement disorders.

Patients And Methods: The study involved 10 patients of both sexes at the age from 32 to 70 years (including 40% of men and 60% of women) presenting with the compromised locomotor function of varying severity associated with the disturbances of cerebral blood circulation caused either by an injury to the brain and spinal cord or by stroke. The transcutaneous electrical spinal cord stimulation was applied using different frequency regimes with the placement of the electrodes in the projection onto the region of TXI-TXII vertebrae.

[CHANGES BLOOD GAS AND OF FREE RADICAL OXIDATION OF LIPIDS IN THE MYOCARDIUM DURING ADAPTATION TO PHYSICAL STRESS].

The article considers the changes of gas composition, acid-base blood balance, lipid peroxidation processes, and activity of the antioxidant defense system in rat myocardium in the course of adaptation to physical activity (swimming). It has been found out that during the first five days physical activity is accompanied by hypoxia, acidotic blood changes, and increase of lipid peroxidation processes in myocardium. Adaptation to swimming activity (15-30 days) leads to hypoxic and acidotic blood changes, and increases antioxidant defense system in myocardium.

[Systemic and organ mechanisms of the organism oxygen supply in high altitude].

Organ and systemic mechanisms of organism oxygen supply in adaptation to high altitude of the Tien Shan (3200 m above sea level) were studied in the experiments on dogs. It is shown that in the first few days in the mountains (5-7th and 15th days) oxygen supply of the body is due to the increased delivery of O2 to organs and tissues; in the process of adaptation (30 days), the efficiency of tissue utilization of O2 increases. Changes of organ blood flow in visceral and somatic organs, features of compensation of the tissue hypoxia and oxygen supply of the heart, brain, skeletal muscle in different periods of adaptation to high altitude were established.

[Effect of head-down tilt on respiratory responses and human inspiratory muscles activity].

The effect of head-down tilt on respiration and diaphragmal and parasternal muscles activity was investigated in 11 healthy subjects. The short-time (30 min) head-down tilt posture (-30 degrees relatively horizont) increased the inspiratory time (P < 0.05), decreased breathing frequency (P < 0.

Restructuring of the thyroid gland in primary hypothyroidism under the influence of intermittent hypobaric hypoxia.

We studied the effect of intermittent hypobaric hypoxia on morphofunctional characteristics of the thyroid gland during experimental hypothyroidism. Functional activity of the thyroid gland increased in the early period of hypoxia. Morphofunctional parameters reached a constant level with increasing the duration of hypoxia to 7-15 days.
