Effects of glutamine on intestinal permeability and bacterial translocation in TPN-rats with endotoxemia

Figure 2 Alterations of structure in mucous membrane of small intestine under microscope. A. The normal structure of jejunum mucosa in normal group rats; B. The normal structure of ileal mucosa in normal group rats; C. Slice of the structure of ileal mucosa in TPN group. The section shows an evident damage in mucosal architecture. The villi become shorter, blunted and swollen. Infiltration of leukocytes occurs within the lamina propria. The lymphatic ducts in lamina propria reveal dilatation and edematous; D. Slice of the jejunal mucosa of LPS group. The villi are more sparse and shorter than control group. It also shows infiltration of leukocytes within lamina propria, and dilatation of lymphatic ducts in lamina propria; E. The section of ileum mucosa of Gln group. The morphology of ileal mucosa is similar to that of control group (B).
