title: Tunica propria in chronic allergic rhinitis. Electron-microscopic study. I. The nasal blood vessels.
abstract: The fine structure of human nasal blood vessels was studied in 15 chronic allergic patients. The venules showed gaping of the interendothelial junctions and lamination of the basal lamina. The capillaries displayed numerous endothelial cytoplasmic processes. The arteriolar walls showed thinning and destructive changes. A reciprocal relation between the vascular endothelium and its basal lamina was deduced.
