From: The role of the 5-hydroxytryptamine pathway in reflux-induced esophageal mucosal injury in rats
Histological assessment of the esophageal mucosa (hematoxylin and eosin ×200) from sham operated rats (A) and GER model rats (B, C). Normal esophageal mucosa is shown in A (controls). The absence of esophageal mucosal inflammation is shown in B (NERD). Basal layer thickening, vascular congestion, and infiltration of inflammatory cells, such as eosinophils, are shown in C (reflux esophagitis, RE).
