Protective effect of glutamine on intestinal injury and bacterial community in rats exposed to hypobaric hypoxia environment

Figure 2 Effects of glutamine on intestinal morphology in rats. Smooth intestinal mucosa with intact epithelia and ordered villi in the control group, atrophic and thinned villi with a loose and disordered arrangement, and exfoliated and incomplete intestinal mucosa in the hypobaric hypoxia (HH) group, and relatively intact intestinal villi with an ordered and tight arrangement in the hypobaric hypoxia + Gln (5.0 g/kg BW·d) (HG) group (hematoxylin and eosin, × 200). A: Control; B: HH; C: HG.
