[Pharmacoprophylaxis of sea-sickness syndrome with the help of homeopathic drug "Avia-more"].

Anti-sea-sickness effect of a new homeopathic drug [see text] and its influence on operator's working capacity during Coriolis acceleration was evaluated in blind placebo-controlled investigation conducted in practically healthy volunteers with low vestibular resistance. For comparison "Dimenhydrinate" was used. The investigation has demonstrated that [see text] has rather strong anti-sea-sickness effect, is comparable with dimenhydrinate effectiveness and prevents the development of disorders in sensory-and-motor and cognitive functions during the influence of static-and- kinetic loads. According to the data obtained the protective action of [see text] is most likely connected with adaptive effect on organs and systems that form the functional protective system against sea-sickness. The negative influence of the drug on CNS complex functions was not observed that allows recommending its prophylactic use in subjects with low sea-sickness resistance including the operators.

[Problems of hearing loss in aviation engineers (professional and ecological aspects)]. / Problema tugoukhosti u spetsialistov inzhenerno-aviatsionnoi sluzhby (professional'nye i ekologicheskie aspekty).

Health standards for noise were exceeded 3 times when noise characteristics were measured at jobs and in apartments of engineers engaged in maintenance of modern aircraft. These specialists were exposed to noise in working hours and at night. Audiometry registered hearing problems in 69% of the examinees. 20% of them had hearing loss of the second degree. In engineers living closer to airports hearing was damaged more seriously, especially at frequencies 1000-8000 Hz. This fact demonstrates ecological implication of non-occupational acoustic load. Relevant regression levels were derived from correlation of noise doses with tonal hearing. Natural and experimental investigations proved efficacy of impedancemetry in objective assessment of noise-induced affection of the organ of hearing and hearing restoration in subjects occupationally exposed to noise.

[Current aspects of the noise problem in aviation medicine]. / Sovremennye aspekty problemy shuma v aviatsionnoi meditsine.

The authors discuss the problem of improvement the noise factor prevention in aviation medicine. The analysis of the real acoustic load on aviation engineer specialists, performing maintenance of the modern military aircraft have been given. The authors show the importance of the approach to the aviation noise as an ecological significant factor, that means taking into account the acoustic load during work time as well as during rest-sleep periods. The authors suggested the advanced complex of the preventive measures for the purpose of optimization of the noise exposure on the aviation specialists.
