title: [Elastolytic activity of bronchoalveolar lavage fluid in acute lung inflammatory injury].
abstract: Elastolytic activity in bronchoalveolar lavage fluid in the lung with acute inflammatory injury and properties of different proteinase inhibitors for its correction was established. It was determined, that 4/5 of elastolytic activities are submitted to neutrophile serine proteinase (EC 3.4.21.37) and 1/5 of elastolytic activities - metalloenzymes macrophages origin (EC 3.4.24.65). Inhibition of elastase-like activity with the use of three proteinase inhibitors: contrycal, ingiprol and thermo- and acid-stable proteinase inhibitor from rabbit blood showed more intensive ability of thermo- and acid-stable proteinase inhibitor to inhibit pancreatic elastase and pull of neutrophil and macrophage elastase. Preventive use and treatment of proteinase inhibitors effectively suppressed activation of proteinases in the acute lung inflammatory injury.
