PANE attenuated the infiltration and degranulation of mast cells in the duodenum. Tissue sections of the duodenum were stained with toluidine blue. (A) Representative sections of the duodenum were shown (original magnification, ×400). Black and red arrows indicate non-degranulated and degranulated mast cells, respectively. (B) The number of total and degranulated mast cells was counted manually. Three measurements per section were counted. Data are expressed as mean ± SE of 11 samples per group pooled from 3 independent experiments. ^*, p < 0.05 compared to the OVA group.
