[Contents of glycogen, glycolytic activity and contents of metabolites in the atrioventricular system of bovine hearts (author's transl)]. 1978

W Thorn, and D Nitsche, and B Harms, and B Müldener, and J Bartels

In the atrioventricular system (AVS) consisting of the compact node, the penetrating bundle and the branching bundles of about 250 bovine hearts there were made several studies: 1. In quickly removed and fixed specimens (distal AV-node, penetrating bundle) determination of a metabolic state with respect to glycogen, glucose, lactate, ATP, ADP, AMP, creatinephosphate, total creatine, gluc-6-phosphate, fructose-6-phosphate, fructose-1,6-diphosphate, dihydroxyacetonphosphate and pyruvate. 2. Determination of glycogen contents and glygolytic activity in AVS and its parts for ischemic times up to three hours. 3. The determination of metabolic contents in samples of connective tissue in atrium and ventricle of bovine hearts. The AV-nodes are poor in glycogen comparable with glycogen content of central nervous system and other ganglia. Penetrating bundles of Hiss and branching bundle belong after liver to the glycogen richest parenchyma of animal tissues. Even after ischemia of 3 h only a part of glycogen was recovered as lactate. The greater part of glycogen must be considered as a structural element of Hiss bundle and branching bundles of the ventricles.
