[Thyroid state in workers of mechanical rubber production under complex exposure to occupational factors].

Complex study of thyroid gland covered workers engaged into mechanical rubber production, under exposure to complex of occupational factors. Chemical analytic study revealed 5.5 times excess of acrylonitrile content of expired air in examinees of the study group if compared to the reference group. Ultrasound examination data demonstrate structural changes in thyroid gland in 72% of the workers (diffuse changes and nodular masses). As early dysadaptation markers, findings are 1.3-1.7 times increased antibodies to TPO and higher TSH level. These disorders can indicate autoimmune processes in thyroid tissue and strain of compensatory adaptational mechanisms of pituitary-thyroid regulation.
