Fig. 3. Representative cases showing changes in histologic findings after treatment with ilaprazole. Several histologic findings showed improvement following treatment. The thickness of the basal layer changed from 40% (H&E, ×100) (A) to 10% (H&E, ×100) (B). The length of papillae changed from 80% (H&E, ×100) (C) to 40% (H&E, ×100) (D) of the total epithelial thickness. Infiltration of T lymphocytes changed from 16/high power field (H&E, ×200) (E) to 4/high power field (H&E, ×200) (F). H&E, hematoxylin and eosin.
