The purpose of the study was to observe effect of chinese medicine “Qing Yi Tang” on the repair of injury of intestinal mucosa in acute necrotizing pancreatitis (ANP). Dogs ANP model were induced by injection of 5% sodium taurocholate (0.5 ml/kg) with 3 000 u/kg trypsin into the pancreatic duct. Diamine oxidase and anylase activity in blood, protein and MDA levels of ileal mucosa were to be determined in ANP and after treatment of “Qing Yi Tang”. Intestinal permeability was also to be studied, LPS and bacteria translocation (BT) were obseved. All animals were sacrificed on day 7, the tissue of ileal mocosa was collected for histological and ultrastructural studies. The results showed that after treatment with Chinese medicine “Qing Yi Tang”, the injury of intestinal mucosa in ANP reduced. The length, height, area and protein of ileal mucosa increased significantly, intestinal permenbility decreased, the levels of LPS reduced in 1-2 times, and organ BT rate also reduce in 50%. The results indicated that chinese medicine “Qing Yi Tang” had good effect on improving repair of intestinal mucosa injury, protecting gut barrier function, reducing the incidence of LPS and bacteria translocation.
