ADENINE NUCLEOTIDE METABOLISM DURING HEPATIC ISCHEMIA AND SUBSEQUENT BLOOD REFLOW PERIODS AND ITS RELATION TO ORGAN VIABILITY

Abstract

In an experimental model system for liver transplantation, the ability of the rat liver to synthesize ATP and to maintain adequate energy charge and total adenine nucleotides during restoration of hepatic blood flow following warm ischemia was found to determine tissue viability and survival of the animal. A portafemoral shunt prepared to relieve portal congestion enhanced the rate and extent of ATP resynthesis by the reflow following hepatic ischemia and this was accompanied by an increase in the survival rate of the rat.
