Human nasal epithelium and cellular elements in chronic allergic rhinitis. Electron-microscopic study.
The fine structure of human nasal respiratory epithelium and tunical cellular elements was studied in 15 chronic allergic patients. The epithelium showed characteristic morphological details suggestive of oedematous infiltration occurring in these cases. Eosinophils, mast cells and plasma cells showed ultrastructural changes explaining the role played by each of them in allergic rhinopathies.
