[Toxic pneumosclerosis and alveolitis in workers of hydrometallurgic production of nickel].

The author detected a considerable occurrence (14.4%) of toxic pneumosclerosis resulting from extrinsic toxic alveolitis in workers engaged into hydrometallurgic nickel production. Pathogenesis of the condition includes changes in lung surfactant, dysbalance between lipid peroxidation and antioxidant activity, immune disorders, formation of circulating immune complexes.
