Quantitative measurements of ileal ischemic-reperfusion injury performed by digitizing projected microscopic image with computerized planimeter. a, Muscularis thickness; b, mucosal thickness; c, transmural thickness (each measured at 30 points around circumference in each section); d, percentage of luminal circumference covered with mucosal epithelial cells; e, villar surface circumference measured and divided by bowel circumference at base of villi f, to calculate villar surface ratio.

3. Fig. 2
Representative transverse sections from nonischemic ileum (A) and ileum after 110 minutes of ischemia and 24 hours of reperfusion in (B) glucagon-treated and (C) control rats. Control rats showed near-total mucosal loss, with absent epithelial coverage (C), whereas glucagon-treated rats showed more mucosal preservation with epithelium often intact (B).
