[Rhythmosuggestive compensation and unconscious mechanisms of regulation].

The article describes rhythm suggestive compensation (RSC), a new method of autonomous crew psychological support based on recruitment of cerebral mechanisms of regulation (psychological defense). The method integrates several ways of optimization such as rhythmic stimulation, binaural drumming and verbal suggestion. Procedure of rhythm suggestive compensation is tailored to each individual person with allowance for actual functional interaction of the brain hemispheres, person specific reaction to suggestive information and psychological defense. Meaningful suggestive patterns are modulated by an algorithm and harmonize with rhythmic sensory stimulation. Hence, the controlled change in activities of the hemispheres and different regions of the brain is combined with the effective form of suggestion. Effectiveness of rhythm suggestive compensation was verified with two groups of participants in combat operations (n=5). Compensatory procedure for Group-1 consisted of a simple combination of rhythmic audiovisual stimulation and verbal suggestion. Effectiveness was evaluated by cerebral potentials evoked by emotionally engaging images. Group-2 was treated with the RSC procedure. RSC was found to outdo rhythmic audiovisual stimulation. In addition, it was shown that regular repetition of the rhythm/suggestive procedures does optimize mental state and builds up a stable mental set.

[Hemoaggregation dynamics in human-operator during percutaneous laser blood irradiation].

The experiment with essentially healthy male subjects no older than 50 involved functional load testing and irradiation by a low-energy helium-neon laser according to the standard therapeutic regimen (0.2 ml/V/ 30 min/10 sessions). Biomedical evaluation of hemoaggregation was made by 30 parameters of a multifunctional diagnostic system characterizing three blood aggregation levels: rheological (biophysical), coagulolytic (biochemical) and system (mathematical). The investigation resulted in delineation of a single-vector hypodynamic transformation of biophysical and biochemical modules, i.e. decrease in the rheological and coagulative potential mediated by a moderate platelets disaggregation (24.6%) and hyperactivation of plasmin proferments in euglobulin fraction (126.76 %). Added sessions of percutaneous laser irradiation of blood were shown to induce a medium imbalance of biophysical and biochemical hemoaggregation. At the same time, low-energy laser did not modulate significantly the general functional state of human operator as the rheological and coagulative protective potential of organism remained reasonably high (88.89 and 87.5 %, respectively).
