[Changes in the psychophysiological status of operational workers resulting from the occupational load].

The authors studied psychophysiologic state of operators in coal industry and metallurgy, who were considered healthy and suitable for the work. Only 60% of the examined metallurgy operators and 21% of those engaged into coal industry appeared to meet the occupational medical requirements. By the end of the working shift 50% of the operators showed decrease of attention and 28-36%--depression of visual and hearing memory. Occupational overload induced compromised psychophysiologic parameters in 70% of the examinees. Heating combined with other hazards resulted in marked asymmetry of heating sensation, changed body heating, lower hearing sensation, worse attention, memory, decision making, emotional state.

[The stability of the hearing function as a problem of otoergonomics].

Hearing stability was measured by the method using physiologic dependence: the better were body possibilities to resist the unfavourable effect of acoustic environment, the higher was the tolerance threshold. Hearing stability measured by the suggested method appeared to be an individual stable characteristic that can be predicted.

[Signs of chronic overheating in miners of deep coal mines].

Both miners exposed to high temperature and excess heat and miners working under permissible temperature conditions (a control group) had similar nonspecific signs, i. e., complaints of heartache and headache, erethism, flaccidity, hydrosis, degradation of appetite and sleep, vertigo, dimness, the sense of air shortage, palpitation in rest, uncertain gait, muscle spasm. There were also presented the following objective data: tremor of close eyelids, asymmetry of tendon reflex, convergence weakness, emotional lability, changes in orthostatic test results, higher Kerdau index, instability of sensitizing Romberg's test. The above signs were more pronounced in miners exposed to high temperature, thus it was possible to regard them as indicators of miners' chronic overheating.

[Clinical symptoms of chronic hyperthermia in miners of deep coal mines].

Results are discussed of investigations with the purpose of analysing the clinical manifestations of long-term effects of the thermal factor on the body of miners of deep coal-mines aimed at the diagnosis of chronic hyperthermia. It shown that miners working in hyperthermia conditions showed prevalence of vegetovascular and astheno-neurotic syndrome.
