Representative photomicrographs of sections of rat ileum examined under light microscopy after staining with hematoxylin and eosin. Samples were harvested from the five treatment groups at the end of the study. The control samples show severe reperfusion injury characterized by profound loss of villus height and denudation of the villus epithelia. Samples from rats treated with L-Arg are much less affected with less loss of epithelial cells and more defined crypt architecture. The rats treated with L-NAME before L-Arg or the ones treated with D-Arg are similar to the control group. The Sham-negative control group shows essentially normal small bowel.
