Outline of Final Research Achievements

We succeeded to obtain the "Proof of Concept" that combined therapy against the marginal grafts, including steatosis and DCD liver, could reduce ischemia and reperfusion injury. Using novel preservation solution, perfusate for machine perfusion, and hydrogen gas, graft weight gain and intrahepatic resistance during CS , HOPE and/or reperfusion were well controlled. Although bile production was not fully resucitated in DCD graft subjected to extended cold preservation, it would be resolved by perfusion from the artery. We believe that our method would become a choice to utilize the marginal grafts, and thereby resolving, at least to some extent, organshortage.
