[Electron microscopic and radioautographic study of the bronchi in chronic inflammation as affected by helium-neon laser treatment].
Structural-metabolic changes were studied in 98 biopsies of large bronchial mucosa from 39 male patients with chronic suppurative lung diseases. It was shown (by the level of DNA and RNA synthesis) that the proliferative and metabolic processes were induced by endobronchial treatment of the damaged epithelium with helium-neon laser which passing through a number of transitional stage recovers its structure and differentiation to ciliary and goblet cells with normal ultrastructure. In lamina propria hyperemia, intensive leukodiapedesis, leukocyte infiltrates and granulations develop and proliferative and metabolic activity of endotheliocytes and interstitial cells increases, which results in the formation of delicate fibrous connective tissue. Simultaneous reorganization of the epithelium and underlying connective tissue is interpreted in terms of parenchymatous-stromal interactions.
