title: [Ultrastructural characteristics of the bronchial epithelium in pulmonary tuberculosis (according to biopsy material)].
abstract: Biopsy materials of the wall of the lobar and segmental bronchi obtained from 345 patients with pulmonary tuberculosis were studied. In 25 patients pathohistological investigations were supplemented with electron-microscopy studies. Of 345 biopsy specimens tuberculous inflammation was found in 5 cases. The ultrastructural analysis showed the sequence of changes occurring in the cells of the bronchial epithelium in chronic inflammation: in the development of sclerotic changes in the wall of the bronchus hyperplasia of ultrastructures was followed by their diminution and desctruction.
