Histological characteristics of the of ileum segments in the I/R rat model. H&E staining showing normal histology of the ileum structure of rat in the sham group (A), showing the massive epithelial lifting, dilated capillaries, hemorrhage, and ulceration in the I/R group (B), and showing glutamine pretreatment results in significant structural improvement as evidenced by decreased edema and inflammatory cell infiltration in intestinal (C). Chiu’s score of comparison in these three groups (D). Magnification, 40×. **, P<0.01 vs. I/R group.
