Core Tip
Core tip: A controllable rabbit model of intestinal obstruction was established. This model demonstrated that intestinal obstruction (1) induced intestinal epithelial cell damage and reduction; (2) disrupted the balance of intestinal microorganisms by abnormal proliferation of pathogenic bacteria; and (3) disrupted the intestinal immune system, observed as a decrease in the number and area of Peyer’s patches, and alteration of CD4+ T cell number and CD4/CD8+ T cell ratio. Furthermore, the levels of ornithine decarboxylase activity and citrulline and claudin 1 expression could serve as indicators of intestinal epithelial cell damage.
