[Radioautographic study of DNA synthesis in bronchoalveolar lavage macrophages during chronic inflammatory processes in the lungs].
The cells obtained by broncho-alveolar lavage from patients with chronic pulmonary inflammations were investigated using light and electron microscopy and radioautography. Proliferative activity of lavage alveolar macrophages was studied by 3H-thymidine in vitro incorporation. The labelling index of alveolar macrophages was up to 0.2% in chronic bronchitis and 1.25-3.33% in chronic destructive inflammation. The enhancement of human alveolar macrophage proliferation in chronic pulmonary destructive inflammation is of great importance for the maintenance of the number of mononuclear phagocytes responsible for cellular protection of respiratory lung structures.
