The Antioxidant System of the Respiratory Tract Antioxidant Effectors in Supraepithelial and Extracellular Space (Part 1)

Abstract

The review of literature presents the current data about the antioxidant system of the respiratory tract. The localization of the components and functioning of the enzyme link of antioxidant defense in the respiratory tract are described. The protein content of the bronchoalveolar lavage is characterized. The changes in the content of various proteins in the bronchoalveolar lavage fluid after exposure to an allergen in patients with bronchial asthma are presented. There were shown the function and localization of non-enzymatic bioantioxidants of lung fluid. The characteristics, synthesis induction and physiological role in the respiratory tract of the antioxidant enzyme of lung fluid — extracellular superoxide dismutase were considered in detail.
