OBJECTIVE: To evaluate the effects of the use of gadolinium chloride before and after induction of acute pancreatitis with sodium taurocholate 3% in rats. METHODS: Wistar rats were divided into five groups: SF - control with saline intra-ductal and IV; GD control with saline intra-ductal and gadolinium chloride IV; TS - with AP control induced by sodium taurocholate 3% and saline IV; GDTS - pre-treatment with GD (24 hours before the induction of AP) and TSGD - treatment with GD (1 hour after the induction of AP). Analysis was made in serum amylase, transaminases and TNF-á; determination of the MPO activity in lung tissue, lung and pancreatic histology. RESULTS: The number of dead animals before the end of the experiment was significantly higher in TSGD (P = 0.046). The scores of pancreatitis and lung damage were higher in the groups that used sodium taurocholate compared to groups with intra-ductal infusion of saline solution. There were no differences in other variables studied when comparing TS, GDTS and TSGD groups. CONCLUSION: The benefits with the use of gadolinium chloride as a prophylactic and therapeutic drug were not demonstrated.
