title: [Evaluation of matrix metalloproteinases (pro-MMP-1, MMP-2,8) and their inhibitor (TIMP-1) contents in patients with occupational lung diseases].
abstract: Studies of matrix metalloproteinases in patients with occupational bronchopulmonary diseases and in individuals exposed to asbestos dust revealed hyperactivated protease system--lower level of MMP-1 proenzyme and increased production of TIMP-1 (metalloproteinases inhibitor)--in all the examinees groups. Patients with pneumoconiosis and occupational dust bronchitis demonstrated increased neutrophilic elastase that is activator of metalloproteinases inducing sclerotic changes and pulmonary fibrosis.
