Euro-Collins solution versus UW-solution for long-term liver preservation in the isolated rat-liver perfusion model.
To compare UW-solution (UW) and Euro-Collins (EC) for long-term liver preservation we investigated the morphology and metabolic capacity of rat liver after 18 and 42-hours cold-storage in either UW or EC. After harvesting the rat liver was transferred to a perfusion chamber where it was perfused for 10 min with UW or EC at 4 degrees C. Thereafter livers were stored at 4 degrees C in UW or EC for 18 hours (both groups n = 6) or for 42 hours (both groups n = 8). After 18-hr or 42-hr cold-storage a 2-hr warm perfusion (37 degrees C) was started with Krebs-Ringer solution with carbogen to which 125Iodine-triiodothyronine (T3) was added. Control livers (n = 8) were immediately perfused with Krebs-Ringer without cold-storage. The following parameters were assessed: ASAT-levels in the perfusate, T3-metabolites in the bile and the perfusate, the perfusion pressure, the volume of bile secreted and light-microscopical morphology at the end of the warm perfusion period. After cold storage in UW-solution the ASAT-levels in the perfusate were lower than after storage in EC as well as the perfusion pressures. These livers demonstrated a better T3-metabolism and secreted more bile than EC-stored livers. Histological examination showed more tissue damage in the EC-stored livers than in the UW stored livers. We conclude that cold-storage of rat liver in UW-solution resulted in a better morphology and metabolic capacity as compared with EC-solution.
