[Indicators of phospholipase activity, lipid peroxidation and antioxidants in bronchial secretions from children with bronchopulmonary diseases].

Lipid peroxidation, activity of phospholipases and antioxidants were studied in bronchial secretion products of 5-14 years old children with bronchial asthma. During the acute period of the disease of lipid peroxidation as shown by estimation of hydroperoxides, malone dialdehyde, diene conjugates and Shiff bases and the activity of endogenous phospholipases were distinctly stimulated. Simultaneously, deficiency of endogenous antioxidants, especially of beta-carotin, was observed in the bronchopulmonary system.
