Functional morphology of tonsillar crypts in recurrent tonsillitis.

摘要: The cryptal epithelia contained three types of micropores (termed microcrypt) in association with free cells. Type III microcrypts appeared between ordinary epithelial cells microridges and "specialized cells". specialized consist ciliated non-ciliated having secretory granules pinocytotic vesicles. Horseradish peroxidase (HRP) was taken up by phagocytes which protruded from the microcrypt superficial squamous vesicles idiopathic hypertrophic tonsils. It is suggested that have two contradictory functions. One an active absorption exogenous antigens; other exclusion invasions according to mucociliary function. In recurrent tonsillitis, HRP remarkably detected dilated stratified clefts, tunnels, subepithelial layers lumen high endothelial venules. occurrence sclerotic germinal centres focal infection, greater than tonsillar hypertrophy, whereas incidence appearance less frequent acute tonsillitis infection.
