Table 1. SCHEME OF EXPERIMENTAL PROTOCOL

LTX = liver transplantation; NELP = normothermic extracorporeal liver perfusion; UW = University of Wisconsin preservation solution.

In Group 1 transplantation was carried out directly after organ harvest. Prior to transplantation, livers in Groups 2 and 3 were preserved for 4h in cold UW solution or perfused for 4h at 37°C, respectively. In Group 4 1h of complete warm ischemia in a non heart-beating donor pig preceded liver transplantation, in Group 5 warm ischemia was followed by 4h cold preservation in UW, and in Group 6 WI was followed by 4h NELP.
