[Proteinases in the bronchopulmonary apparatus of rats with bronchial anaphylaxis].

Proteolytic activity was studied in bronchoalveolar lavage in dynamics of rat bronchial anaphylaxis; in the disease alkaline proteinases were activated. Physico-chemical properties of an alkaline proteinase, isolated from the rat lavage, were studied. Quantitative metabolic patterns of the enzyme metabolism, involving the rates of its synthesis and decomposition as well as a period of the newly synthesized protein functioning, were evaluated. Under conditions of bronchial anaphylaxis the parameters of the proteinase turnover were altered in bronchopulmonary system.
