Over-starvation aggravates intestinal injury and promotes bacterial and endotoxin translocation under high-altitude hypoxic environment

Figure 3 Scanning electron microscopy. A smooth surface of intestinal mucosa with a clear structure as well as complete and orderly villi in group C (A) (× 6900), atrophic epithelial structure of intestinal mucosa and lodging villi accompanying a rough surface with disordered villi and widened villous spaces in group H (B) (× 6900), severely injured intestinal mucosa as well as disc-shaped cells and cellulose in mucosal defects along with evident atrophy and disordered villi with widened villous spaces and exfoliated microvilli in group HH (C) (× 11 500), almost intact intestinal mucosa with orderly villi and less effusion but no disc-shaped cells and cellulose in group HG (D) (× 11 500).
