[Radionuclide evaluation of the mucociliary function of the mucosa of the nasal cavity in chronic lung diseases].

The authors presented their first experience of radionuclide assessment of the nasal mucosal transport (NMT) in 39 patients with chronic bronchopulmonary pathology (14 adults and 25 children) to detect patients among them with suspected syndrome of primary ciliary dyskinesia (SPCD). In 18 patients the test was positive excluding SPCD as a cause of a chronic inflammatory pulmonary process. In 21 patients NMT was absent, 2 of these patients had Kartagener's triad serving as a kind of model confirming the data on NMT. The authors proposed the method as a screening test due to its non-invasiveness and simplicity in patients with chronic inflammatory pulmonary diseases in order to detect among them patients with suspected SPCD for further examination using invasive methods.

[Changes in the structure of the cilia of the ciliated epithelium of the bronchi in Kartagener's syndrome in children].

Biopsies of bronchial mucous membrane taken from 4 children with Kartagener's syndrome and 10 children with chronic pneumonia were examined electron microscopically. Structural changes in cilia and apical parts of cells are detected in all patients with Kartagener's syndrome. Cilial changes provoked by chronic inflammatory process are shown. The importance of ultrastructural investigations of bronchial mucous membrane cilia in the understanding of pathogenesis of chronic lung conditions in children is underlined.

[Glycerol models of the ciliated epithelium of bronchial mucosa and their use in the diagnosis of chronic nonspecific lung diseases].

The method of extraction of ciliated epithelium from biopsy samples of human bronchial mucosa with glycerol is suggested. Permeabilized cilia of glycerol-extracted cells can be easily reactivated by exogenous ATP. This method was used for the study of ciliary dyskinesia in patients with chronic lung diseases. It was shown that in patients with Kartagener's syndrome neither freshly-isolated, nor glycerol-extracted ATP-treated cilia were motile. On the other hand, in some patients with bronchial asthma ATP reactivated glycerol-extracted cilia, while cilia of freshly-isolated cells remained immotile. The study shows that glycerol permeabilization and reactivation by ATP can be used for the analysis of cilial contractile apparatus in patients with chronic lung disease.
