title: [Cytogenetic variants of dysregenerative and precancerous epithelial changes in chronic inflammatory pulmonary diseases].
abstract: Surgical material of the lungs and their parts from 31 patients and open biopsies were studied. Proliferative activity (Ki-67, PCNA) and oncomarkers expression (bcl-2, p-53, c-myc, b-TGF, chromogranin-A) were studied immunohistochemically in the foci of various epithelial changes. It is established that a wide spectrum of alterations in pulmonary tissue is associated with variability of precursor cells and may have nosological features.
