Figure 1 Alterations in architecture of small intestinal mucosa. (HE staining, original magnification: × 100). A: Normal mucous membrane of jejunum in control rats; B: Normal mucous membrane of ileum in control rats; C: Histological changes of jejunal mucosa of group T1 rats. The villi become sparser than those in control. The height and shape of villi are normal on the whole; D: Histological changes of ileal mucosa in PN group rats. The section shows a severe atrophy in mucosal structure. The villi become shorter, blunt and swollen; E: Histological changes of jejunal mucosa of Sep group. The villi are sparse and shorter than those of control group.
