Hypoxic conditioning of special task-force personnel was carried out using an original approach based on biological feedback under conditions of using helium instead of nitrogen for oxygen dilution. Conditioning was carried out prior to placing test subjects into an artificial hypoxic fireproof medium in a pressurized sealed chamber. The hypoxic breathing medium consisted of 93% v/v He and 7% v/v O2 in the conditioning phase and of 70% v/v He and 30% v/v O2 in the restoration phase. Test parameters were the times required to normalize heartbeat, blood hemoglobin oxygenation (SpO2) measured by pulse oximetry, physical performance, anaerobic threshold, visual functions assessed be spatial contrast sensitivity, and sensorimotor responses. Positive changes in the restoration of all test parameters after acute hypoxia were found. Functional performance assessed as suggested by T.D. Loskutova was improved by 15,1%, and simple visuomotor responses were accelerated by 6,95%. The approach is recommended for further developing of targeted particular techniques of discontinuous hypoxic conditioning.

Experiments were carried out to assess the toxicity of combustion products of materials used in shipbuilding for decorative and finishing purposes and for furniture manufacturing. The toxicity of combustion products of poorly inflammable laminar plastics compositions, polyurethane, and combinations of laminar plastics and polyamide films has been shown to increase at temperatures ranging from of 600° C to 800° C. The results show that testing the intact forms of polymeric materials as well their forms included in compositions is warranted.

In the history of development of the Russian Far East Vladivostok naval hospital it occupies a special place, since it begins with the development of the Far Eastern medicine during the period of political transition and geographical discoveries in the XVIII-XIX centuries. This is due primarily to the development of Russian naval forces in the Pacific Ocean, a change of location of the main port of the Pacific Fleet, and with it - and the Naval Hospital from Okhotsk - Petropavlovsk-Kamchatsky - Nikolaevsk-on-Amur - Vladivostok. The 1477 Naval Clinical Hospital in 2017 will celebrate its official anniversary - 145 years, however, the author cites the documents covering the earlier history of this hospital.

The present paper is dedicated to the navy hygienist, Honored Doctor of the Russian Federation Prof. Bosis Ivanovich Zholus whose oeuvre significantly influenced the outlooks and thinking of several generations of Russian navy medical doctors. Approaches devised by him will long be actual and in demand for the preventive trend in health care.
