[Influence of hyperbaric stress on metabolic reactions of the organism of divers, prevention].

Research of metabolic rates is conducted in a blood of the subjects whose professional work is connected with the systematic implementation of diving on the large and medium depths. For restoration of working capacity and preservation of health of divers was carried pharmacological prophylaxis with supplementation "Kalifen", which is the total polyphenol complex isolated from viburnum (Viburnum sargentii Koehne). The blood plasma of divers, investigated after a dive, there was hypertriglyceridemia and hypercholesterolemia, the suppression of esterified liver function, an imbalance of fractional content of phospholipids, the strain of antioxidant defense of an organism and increased lipid peroxidation. Preventive administration supplementation "Kalifen" for 2 months before the dive will help remove metabolic disorders caused by hyperbaric factors, and also to store up of anabolic reserves and increase body resistance level in extreme conditions.

[Acoustic and spirometric indices of the external respiration function of divers using closed oxygenous systems].

The influence of asingle diving in equipment of the closed type using respiratory gas mixture with a risen concentration of oxygen on the external respiration function of divers having small experience of underwater works is investigated by means of a tracheal forced expiratory noise analysis. 16 divers and a control group consisting of 13 men (with the age from 19 to 24 years) were inspected. Duration of tracheal forced expiratory noise was measured. Spirographic indices were registered. 10 divers were inspected in dynamics - before diving and immediately after it. T, FVC and FEV1 changes were tested. Significant differences in T and spirographic indices among groups of divers (before diving) and the control one were not detected. On the whole after diving the only significant reduction of indices in the group of divers was connected with FEV1. Significant individual dynamics of spirographic indices was not found. 2 examined divers showed considerable increase in T reflecting bronchial patency aggravation.

[Influence of heparin on the general adaptation syndrome]. / Vliianie geparina na obshchii adaptatsionnyi sindrom

Administration of heparin led to the block of the alarm reaction of the general adaptation syndrome in rats. The results obtained could be explained by the binding of adrenal cortex hormones by heparin or by an increase in the resistance of tissues to stressors as a result of reversible block of the enzymes of the respiratory energic cycle in the cells.
