[Effects of basic fibroblast growth factor on repairing injury of intestinal mucosa in acute necrotic pancreatitis].

OBJECTIVE: To observe the effects of basic fibroblast growth factor (bFGF) on repairing injury of intestinal mucosa in acute necrotic pancreatitis (ANP). METHODS: Sixteen dogs of ANP animal model were made by injection of 5% sodium taurocholate (0.5 ml/kg) with 3,000 U/kg trypsin into the pancreatic duct. The mucosa structure, content of protein, DNA and malondiethylaldehyde (MDA) were observed after ANP and treatment with bFGF, and the plasma lipopolysaccharide and endothelin-1 were detected. The organs of dogs were made to bacterial culture. Ileal mucosa was collected for histological and ultrastructural studies. RESULTS: The results showed that after treatment with bFGF, the injury of intestinal mucosa in ANP was abated. The length, height and area of mucosa microvillus, the content of DNA and protein of ileal mucosa were significantly increased, while the plasma endothelin-1 and lipopolysaccharide were reduced. The organ bacterial translocation rate was also decreased in 50%. CONCLUSION: bFGF has good effects on abating injury of intestinal mucosa, protecting gut barrier function, reducing the incidence of lipopolysaccharide and bacterial translocation after ANP.
