[Markers of asbestos exposure in workers]

Examination covered 213 workers of asbestos technical ware plant. Standard X-ray examination no pulmonary and pleural changes were revealed. External respiration studies demonstrated moderate ventilation disorders in half of the examinees: in hardware workshop workers--restrictive type disorders, in autofriction components workshop workers--obstructive type ones with hyperventilation. Lower diffusing lung capacity in one-third of the workers in one of two autofriction components workshops proves most likely distributive disorders. Moderately increased serum alveolar mucin 3EG5 in 20% of the examinees could be a predictive criterion of slow formation of chisotyle pulmonary fibrosis.
