The purpose of this study was to use a direct method, that of electron spin resonance (ESR)
spectroscopy, to demonstrate that reperfusion after a period of ischemia results in a sudden …

Photoactivation of rose bengal leads to the generation of reactive oxygen intermediates
(predominantly singlet oxygen with some superoxide anion) which are potentially injurious …

A burst of free oxygen radical production has been demonstrated during the early moments
of reperfusion, coincident with the onset of reperfusion arrhythmias, which can be attenuated …

1 Platelet activating factor (PAF) is often used to study the effects of platelet activation. While
direct myocardial electrophysiological effects of PAF have been described in superfused …

Isolated rat hearts were used to examine whether reperfusion-induced arrhythmias may be
caused by washout of substances accumulating during ischemia. This was achieved by …

1 Idioventricular rate responses and adrenoceptor number have been examined in normal
Langendorff hearts perfused at 70 cmH2O and in 'ischaemic'hearts perfused at 10 cmH2O. 2 …

This study documents the value of continuous observation of nicotinamide adenine
dinucleotide (NADH) fluorescence (NADH-F). NADH-F monitoring is used to identify …

Isolated hearts excised from normotensive (NT) and spontaneously hypertensive (SH) rats
subjected to transient normothermic global ischemia were used to study the effect of chronic …

Study objective–The aim was to exploit species-and age dependent differences in calcium
handling to assess the role of calcium as a mediator of oxidant stress induced injury in the …

MATERIALS AND METHODS 1. Experimental animals and apparatus Wistar rats (250—
350g) were anesthetized with diethyl ether. Sodium heparin (200U) was injected …
