摘 要：AIM： To observe the therapeutic effect of early administration of exogenous Basic fibroblast growth factor （bFGF） on acute edematous pancreatitis （AEP） in rats. METHODS： Thirty male Sprague-Dawley rats were randomly divided into three （n = 10）： normal control group （group Ⅰ）, AEP group （group Ⅱ） and AEP with bFGF treatment group （group Ⅲ）. AEP was induced by subcutaneous injection of cerulein （5.5 μg/kg and 7.5 μg/kg） at 1 h interval into rats of groups Ⅱ and Ⅲ. Three hours after induction of AEP, 100 μg/kg bFGF was administrated intraperitoneally for 1h to group Ⅲ rats. For test of DNA synthesis in acinar cells, 5-bromo-2＇-deoxyuridine （BrdU） labeling solution was intraperitoneally injected into the rats of groups Ⅱ and Ⅲ 24 h after bFGF treatment. The changes in serum amylase, lipase, pancreatic tissue wet/dry ratio were detected. RESULTS： In bFGF treatment group, there was a significant decrease in the volume of serum amylase, lipase and the pancreatic wet/dry weight ratio（1383.0 ± 94.6 U/L, 194.0 ± 43.6 U/L, 4.32 ± 0.32） compared to AEP group （3464 ± 223,7 U/L, 456 ±68,7 U/L, 6.89 ± 0,47） （P 〈 0.01）, and no significant difference was found between bFGF treatment and control group （1289 ± 94.0 U/L, 171 ± 23.4 U/L, 4.12 ± 0.26, P 〉 0.05）. The inflammatory changes such as interstitial edema, polymorphonuclear neutrophUs （PMNs） and vacuolization were significantly ameliorated compared to AEP group （P 〈 0.01）. A small number of BrdU-labeled nuclei were observed in acinar cells of AEP rats （1.8 ± 0.3 nuclei/microscopic field, n = 10） while diffuse BrdU-labeled nuclei were found in bFGF-treated rats （18.9 ± 1.4 nuclei/microscopic field, n = 10） （P 〈 0.01）. Immunohistochemical study showed increased DNA synthesis in pancreatic acinar cells. CONCLUSION： Early administration of exogenous bFGF has significant therapeutic effect on cerulein-induced acute edematous pancreatitis in rats. Its mechanism is related to the amelioration of inflammation and facilitation of pa
