To specify scientifically based method for calculating acoustic load on civil aircraft crew members in cabins, the authors measured noise parameters inside cabins of aircrafts used at present in Russia, and noise-proof properties of domestic and foreign aviaheadsets. Normalized values suggested: equivalent level of A sound over a month (LA,,m), over a year (La); suggestions for reference values: equivalent level of A sound (Leg), over an arbitrary period of piloting length (L,r); coefficient of piloting load. Principles of these calculations are determined. The method is designed as an addition to sanitary rules and regulations 2.5.1.2423-08, determining hygienic requirements to work and rest conditions for civil aircraft pilots.

Vistar male rats were exposed to low frequency noise with maximal range up to 250 Hz with noise pressure of 120.dB or 150 dB once (during 17 minutes) or repeatedly (17 minutes 5 days per week over 13 weeks), after that frequency of chromosomal aberrations in bone marrow cells and serum low-molecular DNA were assessed. In comparison with reference values, single exposure to low frequency noise with noise pressure of 120 or 150 dB reliably increased frequency of%chromosomal aberrations more than 10-fold and caused dicentrics in aberrations spectrum, significally increased serum-low-molecular DNA over 7-fold, with low-molecular DNA level remaining high during 7 days after exposure to low frequency noise. Repeated exposure to low frequency noise with noise pressure 120 and 150 dB resulted in reliable increase of low-molecular DNA level 36-fold and 22-fold respectively vs. reference values. Thus, low frequency noise harms genome, with more frequency of chromosomal aberrations, and increases apoptosis that manifests in higher level of extracellular low-molecular DNA. Some part of the work was performed with governmental financial support of leading universities of Russian Federation (grant 074U01).

Findings are that indivual protective means testing are expedient with consideration of measurements in free space and evaluation of absorbed electromagnetic energy in tissue-equivalent phantoms. Screening coefficient should be assessed in several zones corresponding to location of human vital organs.

Complex study of work conditions and health used V.V. Boiko test for assessment of emotional burnout level in radio and television broadcasting center personnel. Considerable share (53,3%) of main occupations workers in radio and television broadcasting center demonstrates high level of occupational burnout (exhaustion phase has developed or is being developed). Median total points of occupational burnout syndrome equalled 123 (74,0; is5,0) that is higher than the similar parameter for many "subject-object" occupations. Emotional defence is manifested by withdrawal from emotional show at work, increased distance in communication with colleagues, at home with relatives, avoidance of work demanding emotional charge. Longer length of service is connected with less open emotions not only in occupational sphere, but outside profession with relatives, friends. The results obtained point to predisposition for lower performance and health disturbances, necessitate consideration of this factor in complex evaluation of work conditions and health of personnel engaged in radio and television communications.

Over 2002- 2014, a total of 497 cases of occupational cancer was registered, that is less than 0,3% of minimal expected number of cases. Necessity is to urgent improvement of legislation and methodic basis, informational supply, providing qualitative account of occupational oncologic morbidity. Important role in solving this problem could be played by continued sanitary and hygienic certification of caricnogenically dangerous institutions in RF and creation of Federal register (governmental automated information system) of individuals who had (has) occupational exposure to carcinogenic factors.

Findings are that those levels in the city are significantly lower than the general in Russia. Over the studied period, the structure of both types of morbidity did not change, but there was a tendency to decrease both in total and in main entity classes of general and occupational diseases.

Presented literature data and some personal studies characterize current state of industrial medicine topics on fish- processing enterpirses. Absence of systemic studies in these sphere rises many questions on work conditions assessment in connection with contemporary knowledge, evaluation of occupational risk and risk of occupational and occupationally conditioned diseases in major occupational groups.

Relationship was established between intensity of the diagnosed affect and changes in levels of antibodies to proteins S-100, general myeline protein, myeline-associated glycoprotein - that can indicate general neurodegeneration process. Antibodies level can serve as a marker of demyelination intensity in central pathways under exposure to neurotoxicants.

Findings are exceeded hygienic norms on maximal concentrations of 1.2-dichloroethane in a workshop for vinyl chloride production from 1.0 to 2.85 MACs and of vinyl chloride in a workshop for polyvinyl chloride production from 2.06 to 5.52 MACs. Urinary levels of thiodiacetic acid were assessed in workers of vinyl chloride and polyvinyl chloride production in dependence on occupation, length of service and post-contact time.

Among the occupational groups of railway workers in Mongolia, conductors occupy first place in morbidity, with values over 2.4 times higher than an average for all railway workers. Findings are high level of occupational conditionality for cardiovascular diseases (RR = 3.22; EF = 69; c2 = 7.46) and for genito-urinary tract diseases (RR = 4.84; EF = 79; c2 = 20.21), and diseases concerning pregnancy, delivery and post-partum (other obstetric conditions) (RR = 11.85; EF = 92; c2 =.11.21).

Diagnosis of occupational allergic diseases requires thorough systemic approach. Study covered groups of patients that necessitate diagnosis of occupational disease (107 individuals): chemical production workers, gas- arc welder, medical staffers, aluminium production workers, with diagnosed occupational bronchopulmonary diseases. Direction of leucocytes migration in the diagnostic test used was comparable with type of a chemical under study. Correspondence of clinical manifestations and results of inhibited natural leucocytes migration test approximates 70% in chemical production workers and gas-arc welders; 85-90% - in medical staffers and 50% - in aluminium production workers.

Registered- demyelination disorders on lower and upper limbs in vibration disease patients were associated with neurochemical changes in special neural structures (OBM, S-100 protein, DNA, AH-R, DA-R, Ser-R, GAMK-R). Direct proof of demyelination disorders in vibration disease patients are reliable correlation between levels of antibodies to OBM and conduction velocity in distal part of median nerve, in ulnar nerve from elbow bend and lower third of arm, and ulnar residual latency. Diagnosed relations between levels of antibodies to regulatory proteins in nervous tissue (antibodies to OBM and to S-100 protein), neurotransmitters (antibodies to AH-R, DA-R, Ser-R, GAMK-R) and functional parameters of nervous system prove important role of autoimmune reactions in vibration disease pathogenesis.

Findings are that pilots with occupational neurosensory deafness demonstrate disorganized type of EEG, supported by fading alpha-rhythm, increased slow wave activity in delta range. Other changes are decreased conduction velocity in distal part of median and ulnar nerves - that indicates development of demyelination processes. Psychologic studies proved that personality structure in pilots with occupational neurosensory deafness has dominant traits of balanced emotional reactions, constructive ways to overcome difficulties.

Findings are changes in levels of nitrogen oxide, endothelin-1, angiotensin II metabolites in examinees including those without cardiovascular diseases. The genetic conditionality is connected with unfavorable genotypes of polymorphic variants - Met235Thr of AGT gene and Lys198Asn of EDNI gene. Changes in levels of biochemical markers of endothelial dysfunction in individuals exposed to mercury indicate serious endothelial function disorders and are not genetically determined processes.
