[Objectivization of the cytologic signs of changes in the bronchial epithelium in cancer and noncancerous diseases of the lungs].
The cytologic and histologic material from 150 patients and specimens of their 450 bronchi have been analyzed to define the cytological, cytochemical, and histochemical parameters of changes in the bronchial epithelium in pulmonary carcinoma and non-cancer diseases. The data have been statistically processed. Staining according to Pappenheim, Papanicolau (modified by Soviet authors), with hematoxylin-eosin, Brachet's and Feulgen's tests, and detection of mucus and PAS-positive substances according to MacManus and Meyer have been employed in the study. Informative morphofunctional signs on the cytological and histochemical level have been distinguished, that may be used for the differential diagnosis between pulmonary carcinoma and non-cancer diseases.
