Abstract:
:Regional myocardial anoxia was produced in dogs by perfusion of the left circumflex artery (LCA) with deoxygenated blood. Isolated sarcoplasmic reticulum fragments (cardiac relaxing system) showed decreased Ca2+ binding and uptake. The ability of isolated mitochondria to utilise long-chain fatty acids was markedly reduced. This model has revealed inherent biochemical differences between ischaemia and anoxia.
