Fig. 3. Eosinophils and mast cells in the jejunum. Eosinophils and mast cells in the jejunum were detected using anti-MBP immunostain (A) and chloroacetate esterase staining (B), respectively. Red dots indicate MBP+ or chloroacetate esterase+ cells. The numbers of eosinophils (C) and mast cells (D) per mm2 of jejunal lamina propria were quantitated in different groups of mice. Data are expressed as means±SE. MBP, major basic protein; SE, standard error. ^*P<0.001.
