Effect of EPIT on intact or stripped skin on the induction of injuries in esophagus. Microscopic analysis of eosinophils in the esophagus at 100x high-powered fields (a-d). Most eosinophils are located in the lamina propria, submucosa and epithelial layer of the Sham and stripping-EPIT groups and to a lesser extend of the EPIT group. A difference in the thickness of epithelium is observed between naïve/EPIT and Sham/stripping+EPIT. (e) For eosinophils, the results are expressed as number of eosinophils per mm2 and data are presented as means ± SD for each group, * p<0.05, ** p<0.01.
