Representative histological and immunohistochemical views of tissue reactions in the Zo and Zo+Be groups. a Dotted area depicting the only specimen of the Zo group showing a mixed chronic inflammatory cell infiltrate in the subepithelial connective tissue compartment (Zo group, HE stain). b The ICT was commonly composed of CD68-positive cells, lymphocytes, polymorphonuclear leukocytes, and plasma cells (Zo group). c None of the biopsies from the Zo+Be group revealed any detectable ICT areas (HE stain). d Non-infiltrated connective tissue zone with single CD68 counts (Zo+Be group)
