[Means and methods of acoustic protection in aviation: current status and outlook for development].

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.

[A comparative evaluation of the effect of an extremely high-frequency electromagnetic field on cerebral hemodynamics in hypertension patients exposed in different reflexogenic areas]. / Sravnitel'naia otsenka vliianiia élektromagnitnogo polia kraine vysokoi chastoty na tserebral'nuiu gemodinamiku u bol'nykh gipertonicheskoi bolezn'iu pri vozdeistvii na razlichnye refleksogennye zony.

A single session and multiple sinocarotid and temporal exposures to EHF electromagnetic field in patients with stage I and II hypertension had different effects on cerebral circulation Variants of the above treatment are proposed.

[The comparative characteristics of the clinico-physiological action of electromagnetic radiation in the milli- and nanometer ranges in hypertension]. / Sravnitel'naia kharakteristika kliniko-fiziologicheskogo deistviia élektromagnitnogo izlucheniia milli- i nanometrovogo diapazona pri gipertonicheskoi bolezni.

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.

[The mechanism of the action of electromagnetic radiation in the nano- and millimeter ranges]. / Nekorotye aspekty mekhanizma deistvii élektromagnitnogo izlucheniia nano- i millimetrovogo diapazona.

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.

[Use of euphyllin and adrenaline electrophoresis in the sanatorium-health resort treatment of hypothalamic syndromes]. / Primenenie élektroforeza éufillina i adrenalina pri sanatorno-kurortnom lechenii bol'nykh s gipotalamicheskimi sindromami

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.
