Evaluation of Sequential Perfusion With Euro-Collins and Belzer Solutions for Pancreas Preservation in Rats

Abstract Objective To investigate the effect of Euro-Collins and Belzer solutions in a sequential preservation of the pancreas. Methods Forty-five Wistar-EPM rats were divided into four groups, according to the solution used during preservation: (1) saline solution (SF): animals perfused and preserved with saline solution; (2) Euro-Collins group (C): animals perfused and preserved with Euro-Collins solution; (3) Belzer group (B): animals perfused and preserved with Belzer solution; (4) Euro-Collins/Belzer group (CB): animals perfused with equal parts of Euro-Collins and Belzer solutions sequentially and preserved with Belzer solution. After perfusion, the animals underwent pancreas resection and preservation with the respective substance at 4°C. Amylase was measured in the preservation solution after 12, 24, 36, or 48 hours. Finally, the pancreas was analyzed histologically, and a statistical analysis was performed. Results Groups SF and C showed the highest amylase levels in the preservation solution during all periods. The levels were higher than in groups C and CB ( P = .05). Amylase levels were similar in groups B and CB to 24 hours ( P = .05). Histological analysis was significant for analysis of pancreas islet cells and edema. Groups B and CB were histologically similar ( P = .001) and different from groups SF and C. Conclusion Sequential perfusion using Euro-Collins and Belzer solutions was effective for pancreas preservation in rats up to 24 hours.
