A total of 205 studies of hemodynamics and blood gas analyses were performed in relation to hepatic mitochondrial redox state in 23 partially hepatectomized patients. When the blood ketone body ratio (the ratio of acetoacetate to beta-hydroxybutyrate in arterial blood) decreased, that is when the hepatic mitochondrial redox state was reduced, a hyperdynamic state with increased cardiac index, decreased systemic and pulmonary vascular resistance together with decreased oxygen consumption was observed in spite of the increased oxygen availability. Inhibited oxidative metabolism in the Krebs cycle may have resulted in the decreased oxygen consumption and decreased vascular tone. This study supports the concept that the hepatic metabolic derangements due to reduced hepatic mitochondrial redox state may be a factor in the decreased oxygen consumption and hyperdynamic state.

D008930 Mitochondria, Liver Mitochondria in hepatocytes. As in all mitochondria, there are an outer membrane and an inner membrane, together creating two separate mitochondrial compartments: the internal matrix space and a much narrower intermembrane space. In the liver mitochondrion, an estimated 67% of the total mitochondrial proteins is located in the matrix.

D010084 Oxidation-Reduction A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). Redox,Oxidation Reduction
