[Electromagnetic stimulation in diaphragm dysfunction: repetitive peripheral magnetic stimulation as a method of choice during the rehabilitation period after stroke. (Literature review)].

Unlabelled: Diaphragm dysfunction develops in central nervous system damage, chest injuries, complications of cardiac surgery, long-term artificial lung ventilation, respiratory diseases. Anatomical morphological features of phrenic nerves allow to effectively use electromagnetic stimulation methods for functional recovery of the diaphragm in different pathological conditions. Invasive and non-invasive, electric and magnetic methods of stimulation are used depending on the severity of manifestations of the diaphragm dysfunction and its genesis.

[Pre-rehabilitation of oncological patients before extensive abdominal and thoracic surgery: a literature review].

Surgery is one of the leading treatment methods of patients with primary or recurrent malignant neoplasms in the thoracic or abdominal cavity. Extensive abdominal interventions are accompanied by such adverse outcomes as blood loss, hypoxia, inflammation, blood clotting abnormality, emotional and cognitive disorders, that increases the incidence of serious complications and worsens the treatment outcome and life quality in weakened oncological patients. Multimodal pre-rehabilitation before surgery can significantly decrease the incidence and severity of postoperative complications.

[Evaluation of adaptation of animals to hypoxic hypoxia by the multiple regression method].

White mice were exposed to hypoxic hypoxia during 30 days. In the study a correlation between the altitude ceiling and various physiological parameters (body weight, body temperature variations in response to a cold stress (5 degrees C), hemoglobin content, coefficients of adaptive oxygen consumption determined as the ratio of oxygen consumption at 6000 m to that at sea level (K1) and the ratio of oxygen consumption in hypoxic environment to that in a normoxic atmosphere (K2) was established. The data obtained allow the conclusion that the multiple regression method can be used for measuring objectively the tension of regulatory systems and for discriminating stages of animal adaptation to hypoxic hypoxia.

[Combined action on the body of a mixture of the volatile products of lubricating oil thermal oxidative breakdown and of hypoxic hypoxia].

The experiments on white male mice have shown that the combined effect of different concentrations of mixtures of volatile products of thermooxidative decomposition of the lubricating oil 36/IKUA and hypoxia at altitudes 5,000; 7,000 and 8,000 m depends on the intensity of the combined factors. It is indicated that maximally allowable concentrations of the above mixtures in the space cabin atmosphere should be determined, taking into consideration the level of hypoxia.

[Toxic properties of regenerated water containing methyl alcohol].

The experiments carried out on white male rats have shown no significant changes in the animals that may have resulted from their 30-day consumption of reclaimed water which contained up to 34 mg/l methanol and was produced by sorption purification of the atmospheric condensate during a prolonged manned experiment.
