Fig. 1. Histopathologic analysis of duodenal samples of allergic and non-allergic patients.
Mast cells, eosinophils, IgE+ cells, CD45RO+ cells, CD3+ intraepithelial (IELs) and CD3+ lamina propria (LPLs) cells were counted in 6 villi of duodenal samples of allergic (N: 8) and non-allergic patients (N: 8). Cells were detected by Giemsa or hematoxylin/eosin staining (mast cells and eosinophils, respectively) or by immunohistochemistry using anti-IgE, anti-CD45RO or anti-CD3 monoclonal antibodies. Statistical analysis revealed no significant differences between different groups of patients. (Original magnification: 1000x except for CD45RO).
