| Outline of Final Research Achievements |
There is increasing evidence that continuous thrombocytopenia soon after liver transplant (LT) is associated with a less favorable prognosis. Few pathophysiological studies have assessed post-LT thrombocytopenia. We elucidated the pathogenesis of thrombocytopenia after LT using the allograft tissue obtained after transplant and rat hepatic ischemic reperfusion injury model. Platelets were found mainly as extravasated platelet aggregates in local microenvironments. Platelet count after surgery and graft function were lower in EPA positive group than these of negative group. Pre-treatment of phosphodiesterase-3 inhibitor, milrinone by intraportal administration using splenic injection reduced hepatic ischemia-reperfusion injury minimizing small intestinal injury and platelet depletion in rats
