Rats in the control group were injected with normal saline in the identical location. RESULTS: Serum amylase, plasma endotoxin, intestinal permeability, and pancreatitis pathology scores were all markedly higher in the pancreatitis group than in the control group (P < 0.01). The bacterial infection rate was signif icantly higher in the SAP group than in the control group (P < 0.01), observed in parallel by both bacterial culture and real-time polymerase chain reaction. Acute damage of the pancreas was observed histologically in SAP rats, showing interstitial edema, leukocyte infiltration, acinar cell necrosis and hemorrhage. The microstructure of the intestinal mucosa of SAP ratsappeared to be destroyed with loose, shortened microvilli and rupture of the intercellular junction, as shown by electron microscopy. CONCLUSION: Significant gut barrier damage and intestinal bacterial translocation were def initely observed with few potential study confounders in this SAP rat model, suggesting that it may be an appropriate animal model for study of gut barrier damage and bacterial translocation in SAP.展开更多
