ABSTRACT
Objective To investigate the infiltration of inflammatory cells and the pathogenesis of nasal polyps. Methods the nasal polyps were obtained from 42 patients undergoing nasal operations. The tissues from each patient were stained with HE and Toluidine Blue for eosiophils, lymphocyte, plasma cell and mast cell and observed under the light microscope. A mean number of the above cells were counted. All data were analyzed with the Ttest. Results Eosinophils were found predominantly in 12 polyps(28.57%). Lymphocyte infiltration was shown in the other 30 polyps (71.43%). Furthermore, many mast cells with only a few eosinophils were found in the lymphocyte infiltration polyps; the number of mast cells in these polyps were much more than those in eosinophil accumulation polyps with a very significant difference(P<0.01). Conclusion The accumulation of eosinophils in the nasal polyps does not appear to be related to the presence of mast cells and allergy. The disorder of immunity may play an important role in the formation of nasal polyps.
