RESUMO
Heat-induced lesions in miners are characterized by syndrome of vegetovascular dysfunction presenting with a damage to the segmental and suprasegmental structures of the vegetative nervous system, worsening of the bodily heat status, decrement of physical performance. A distinguishing feature of vegetovascular dystonia in acute overheating is activation of sympathicus, while in chronic one that of parasympathicus. By patterns of function disorders and degree of their restoration acute overheating can be categorized into the following forms-mild, moderately severe and severe ones. In chronic overheating distinct syndromes are recognized depending upon the particular course of vegetovascular dysfunction, viz., permanent course vegetovascular dystonia, permanent paroxysmal one presenting with varying trend vegetative crises, apparent persistent bradycardia and syndrome of weakness of sinoatrial node. Acute overheating is more commonly seen in those miners with as yet little service duration while chronic overheating occurs more frequently in those persons with more than 8-year record of service in conditions of heating microclimate.

The authors analyzed morbidity and invalidity in miners engaged in liquidation of Chernobyl disaster sequels depending on the duration of stay in increased radiation background, radiation dose, length of work in the mines. Among the nosological entities prevailed vegeto-vascular dystonia, thyroid and gastrointestinal pathology.
