✦ Synopsis
Different acinar glycogen patterns are observed in rat liver after different diets. Experiments were carried out to determine if these patterns depend on the concentration of blood glucose in the various zones of the acinus or on the direction of the blood flow. It is possible to investigate this problem by reversal of blood flow in a perfusion apparatus. Livers were perfused with Krebs-Henseleit solution, the same volume of bovine erythrocytes, and 379 mg% glucose, 2.5% albumin and different quantities of heparin. Perfusion in the normal direction is possible through the vena porta and in the reversed direction by perfusing through the vena cava. The reported results show that glycogen localization depends on the acinar enzyme pattern for glycogen synthesis rather than the direction of blood flow.
