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 degrees 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.

Background: Owing to organ shortage, transplantation of organs from HCV (hepatitis C virus) viremic donors into HCV negative individuals is getting more and more accepted. However, transmission of HCV to the host is nearly universal. Until now it is unknown if preservation solutions (PS) might alter infectivity and stability of HCV in the transplant setting.

Purpose: To compare the efficacy of different types of solutions (Belzer or Euro-Collins) for the preservation of rat pancreas during cold ischemia.
Methods: Thirty Wistar rats were divided into three groups according to the perfusion or storage solution: Group E (perfusion and storage in Euro-Collins solution); Group B (perfusion and storage in Belzer solution) and Group BE (Perfusion in Belzer solution and storage in Euro-Collins solution). After perfusion, the pancreas was excised and stored at 4˚C for 18 hours.

Background: Proximal tubule cells have specialized apical membranes with microvilli that provide an extensive surface area for unidirectional transport of solute from lumen to blood. The major structural solute component is F-actin, which interacts with transmembrane proteins, including ion transport molecules related to normal absorptive and secretory functions. Our study was to evaluate F-actin and fluid absorption (Jv) in proximal tubules after exposure to preservation solutions.

Background: Belzer solution is considered to be the best preservation media used for pancreas transplantation; however, its high cost accounts for approximately 14.5% of all resources allocated by the Brazilian government toward each pancreatic transplant. The objective of the present study was to test a reduction of Belzer solution during pancreas harvest, thereby lowering procedural cost.
