Ischemia/reperfusion injury in porcine intestine - Viability assessment

Figure 3 Light microscopy of selected structures of the jejunum after 4 h of ischemia and 8 h of reperfusion. A: Mucosa and submucosa (HE, × 10), showing necrotic villi, total loss of crypt epithelium, shrinkage of myocytes in the muscularis mucosae, and edema in the submucosa. B: Longitudinal (outer) layer of the muscularis propria, showing edema and extensive shrinkage and loss of myocytes (HE, × 60). C: Circular (inner) layer of the muscularis propria, showing edema and extensive myocyte damage (HE, × 60).
