Research Abstract

Liver transplantation is an effective way to treat patients with severe liver injury. However, retansplantation of the liver is often required predominantly due to primary non-function of a graft. To study the mechanism by which the function of the graft is decreased after transplantation, we have established the method for liver transplantation between normal and analbuminemic mutant rats. when normal rat liver was transplanted to the mutant rat, albumin levels in the peripheral blood increased rapidly. However, transient occlusion of the portal vein followed by reflow was found to decrease hepatic transport functions for cholephilic organic anions. We synthesized a superoxide dismutase derivative that circulates bound to albumin and accumulates in a tissue whose local pH is decreased. Intravenous administration of the derivatized enzyme markedly inhibited the decrease in liver transport function caused by a transient occlusion of the portal vein. This suggests that reactive oxygen radicals might be involved in the pathogenesis of primary non-function of a graft. Thus, control of oxygen toxicity minimize the decrease in the function of a graft. The imjured-site-directed SOD derivative might provide an important method to protect functions of a graft.
