Figure 2. Photomicrograph. The ileum wall of the animals from experimental group I: Structurally intact intestinal mucosa (Hematoxylin-eosin stain [H&E stain], x200).
The histological examination of ileum specimens from animals of experimental group II (I/R) demonstrated the following signs of pathological changes: mucosal destruction; a massive disruption and desquamation of epithelial villi and crypts; submucosa disintegration; lack of clear-cut intercellular junctions in the epithelium. Besides, there were signs of multiple hemorrhages, mucosa inflammation with leukocyte infiltration (Fig.3). An ileum mucosal damage in the specimens from Group II was graded as "5 -disintegration of lamina propria, hemorrhage, and ulceration" (by Chiu et al.).
