Figure 5.

Histological appearance of acid‐injured tissues pretreated with or without sucralfate. Tissues processed at the time of euthanasia (baseline, A) are similar to control tissues (B) mounted on Ussing chambers with occasional apoptotic epithelial cell noted. Acid injury (C) induced moderate to marked epithelial cell sloughing. Treatment with sucralfate concurrent with injury (D) protected against morphologic change induced by acid. These selections demonstrate characteristic changes seen consistently in all samples. Bar = 100 µm
