[Regeneration of the alveolar tree after suppurative-destructive diseases of the lungs]

Electron microscopic examinations of the lungs of animals with the model of experimental staphylococcal destruction of the lungs have revealed the regeneration of lung tissues which took place by the 6th month from the onset of the disease. The stimulating effect of laser radiation on the cell growth at the expense of mitosis was observed in the culture of epithelioid cells of the lung tissue. Findings of bronchography, angiopulmonography and an analysis of the function of external respiration in 10 patients have shown a complete anatomical and functional recovery of the alveolar tissue in sites of the former localization of pulmonary abscesses.
