  • An Experimental Study of Restraining Bacterial Translocation of Acute Necrotizing Pancreatitis

    ObjectiveThe changes of intestinal permeability and relationship of intestinal mucosa and bacterial translocation were studied in rat acute necrotizing pancreatitis (ANP) models.MethodsThe ANP models were made by injection of 5% sodium taurocholate 1.0 ml into pancreatic subcapsula.Then wistar rats were divided into four groups,control group (n=20),ANP group(n=22),treatment model group fed with lactose (n=22) and treatment model group fed with MgSO4 and antibiotic (n=22).After 72 hours,the experimental models were sacrificed.Tissues of pancreas,mesenteric lymph node, ascites were collected for microbiological study.The intestinal permeability was observed by lanthanum tracer.The blood samples were obtained from portal vein and ascites in order to assay the amount of amylase in serum.The pathologic lesions were found in the intestinal villus of the model group, including acute necrosis of intestinal mucosa,necrotichaemorrhage as well as enteroparalysis and a mass of haemorrhagic ascites.ResultsBacterial translocation of model group were markedly elevated than that of control (P<0.05).There were statistically significant differences in bacterial translocation among three model groups (P<0.05).The pathologic lesions were found in the intestinal villus of the model group,including acute necrosis of intestinal mucosa,necrotichaemorrhage as well as enteroparalysis and a mass of haemorrhagic ascites.The lanthanum grain in clearance of intestinal cell of model group can be observed by eletron microscope.ConclusionThere is a severe gut barrier damage and injury in the intestinal mucosa,which lead to bacterial translocation from intestine as the source of pancreatic infection.Cleaning out enteric bacteria,improving intestinal movement and feeding with lactose could decrease bacterial translocation to treat and prevent acute necrotizing pancreatitis.
