Title: [Protective effects of glucagon-like peptide 2 on intestinal ischemia/reperfusion injury in mice]. Author: Guan LL, Gong DZ, Tian N, Zou Y. Journal: Zhongguo Ying Yong Sheng Li Xue Za Zhi; 2005 May; 21(2):192-4. PubMed ID: 21171341. Abstract: AIM: To investigate the protective effects of glucagon-like peptide 2(GLP-2) on intestinal ischemia/reperfusion (I/R) injury in mice. METHODS: Intestinal ischemia/reperfusion model in mice were set up and 32 mice of Kunming species were divided randomly into 4 groups (n=8): Sham group, I/R group, I/R + GLP-2 group and I/R + glutamine group. The morphologic changes of intestinal mucosa were observed under LM. The villus height and crypt depth of intestine, the activity of diamine oxidase (DAO) in intestine and bacterial translocation rates of mesenteric lymph nodes (MLN) were detected. RESULTS: Compared with sham operation group, the intestinal villi were sloughed in I/R group with decreased villus height and crypt depth (P < 0.01), the DAO activities were decreased (P < 0.01), and MLN bacterial translocation rates were increased (P < 0.05). While GLP-2 administration improved the villus damage, increased DAO activity (P < 0.01), and decreased MLN bacterial translocation rates (P < 0.05), compared with I/R group. CONCLUSION: GLP-2 have protective effects on intestinal morphology and barrier function after ischemia/reperfusion injury in mice.[Abstract] [Full Text] [Related] [New Search]
