Biliary tract external drainage protects against intestinal barrier injury in hemorrhagic shock rats

Figure 3 Immunohistochemical analysis of expression of occludin in the ileum. Sham group (A), HS group (B: 0.5 h after resuscitation; C: 1 h after resuscitation; D: 2 h after resuscitation; E: 4 h after resuscitation; F: 6 h after resuscitation) and HS + BTED group (G: 0.5 h after resuscitation; H: 1 h after resuscitation; I: 2 h after resuscitation; J: 4 h after resuscitation; K: 6 h after resuscitation). The expression levels of occludin in the ileum in the HS + BTED group were enhanced significantly compared with the HS group at 4 h and 6 h after resuscitation. HS: Hemorrhagic shock; BTED: Biliary tract external drainage.
