Myocardium
Definition:
(n.) The main substance of the muscular wall of the heart inclosed between the epicardium and endocardium.
Example Sentences:
(1) The acute effect of alcohol manifested itself by decreasing mitochondrial respiration, compensated by increased glycolytic activity of the myocardium so that myocardial energy phosphate concentration remained unchanged.
(2) The myocardium was assumed to be composed of a nonlinear viscoelastic, inhomogeneous, anisotropic (transversely isotropic) and incompressible material operating under adiabatic and isothermal conditions.
(3) Comparison with 99Tc-pyrophosphate uptake in infarcted dog heart, induced by selective obstruction of a coronary artery, suggest that the 111In-labelled F(ab')2 localizes specifically in infarcted myocardium only.
(4) By means of rapid planar Hill type antimony-bismuth thermophiles the initial heat liberated by papillary muscles was measured synchronously with developed tension for control (C), pressure-overload (GOP), and hypothyrotic (PTU) rat myocardium (chronic experiments) and after application of 10(-6) M isoproterenol or 200 10(-6) M UDCG-115.
(5) Distant ischemia was distinguished from peri-infarctional ischemia by the presence of transient thallium defects in, or slow thallium washout from myocardium not supplied by the infarct-related coronary artery.
(6) Administration of one of the precursors of noradrenaline l-DOPA not only prevented the decrease in tissue noradrenaline content in myocardium, but restored completely its reserves, exhausted by electrostimulation of the aortic arch.

(8) Previous studies have reported that the numbers of beta- and alpha-adrenergic receptors increase in ischemic myocardium.
(9) With a series of 117 aortic valve replacements, the authors have examined the results in relation to the method of protecting the myocardium while the aorta is clamped off.
(10) Acute transmural myocardial infarction has been reported to functionally denervate the normal myocardium distal to the infarcted zone by interrupting neurotransmission in axons coursing in the subepicardial region of the myocardial necrosis.
