ABSTRACT
Analysis of the current status of acoustic protection in aviation shows that despite the material progress in the field, risk of professional pathologies in flying and technical personnel is still high. The situation is dramatized by the lack of effective personal and crew acoustic protectors. The authors speculate on applicability of innovative materials and technologies, ingenious designs of earphones and modular prefabricated demountable structures. Tests of proposed personal protectors demonstrated their competitiveness with foreign analogs. Prospective lines of development, e.g. incorporation of active sound absorption systems in existing passive protectors are discussed.

The sinocarotid zone (SCZ) of 127 patients with essential hypertension (EH) stage I and II was exposed to electromagnetic millimetric and nanometric waves. Differentiated indications for laser and short-wave-frequency therapy on SCZ in EH have been formulated basing on the postexposure changes in blood pressure, main complaints, central and cerebral hemodynamics, lipid metabolism, blood coagulation.

It is suggested that there exists not only resonance but also interference interaction between laser radiation, millimetric electromagnetic radiation and dissipative systems. A noticeable role here is played by opiate receptors and their ligands determining cytoprotective, stress-limiting, immunomodulating and other effects of EHF therapy.

The authors propose a comprehensive treatment of patients with hypothalamic syndromes (vegetative-visceral vascular forms) by a differentiated use of electrophoresis of euphellin. This method was efficacious in expressed headaches with increased blood pressure and cerebral vessels tone, crises of a sypmathico-adrenal character. Electrophoresis of adrenalin was mainly indicated in symptoms of sympatho-adrenal insufficiency and crises of a vago-insular structure.
