MAST CELLS IN INFLAMMATORY AURAL POLYPS
This study investigated the presence of mast cells in inflammatory aural polyps using light microscopy. The number of mast cells was increased in all examined cases and varied from 2.33 to 41.54 per mm2• The cells were located most commonly around small blood vessels. Occurrence of mast cells was not different in various types of polyps, but their density was severely increased in active in...

متن کاملChapter 9 : Nasal polyps
Nasal polyps are an easily recognizable clinical entity. They result from the prolapsed lining of the ethmoid sinuses and block the nose to a variable degree depending on the size. On examination polyps appear as pale bags which arise most commonly from the middle meatus and are relatively insensitive when probed. This helps to differentiate polyps from mucosa of the middle turbinate which may ...
متن کاملT helper cell population and eosinophilia in nasal polyps.
OBJECTIVE To analyze the immunological pattern of nasal polyposis in patients with and without allergy, the percentages of CD4+ cells expressing intracellular interferon-gamma and interleukin-4 (T helper [T(H)] type 1 and 2 cells) were measured by flow cytometry in samples from patients with nasal polyps. METHODS Samples from 32 patients (16 atopic, 16 nonatopic) were studied. The fresh nasal...
