Exposure of rats to hyperoxia before organ harvesting protected their isolated hearts against global ischaemia-reperfusion injury in a previous study. The present study investigates whether hyperoxia influences vasomotor function and regional ischaem

This study was designed to evaluate the effects of an ordinary mixed meal on endothelium-dependent vasodilation. Ten young healthy volunteers were given a mixed meal (minced meat sauce with rice, 900 kcal, 34% of the energy content was fat). In the f

The role of adenosine in exercise-induced human skeletal muscle vasodilatation remains unknown. We therefore evaluated the effect of theophylline-induced adenosine receptor blockade in six subjects and the vasodilator potency of adenosine infused in

The aim of the present study was to investigate the effects of experimental diabetes and hyperglycaemia per se on the endothelium-dependent relaxation of isolated canine coronary arteries and to analyse the possible involvement of the cyclooxygenase

Whether or not neurally mediated vasodilation contributes to the rise in skeletal muscle blood flow during exercise in humans remains unknown. Such a mechanism might serve as an important 'feed-forward' regulatory signal causing blood flow to rise pr

Adenosine is released by skeletal and cardiac muscles when their metabolism increases: it serves to couple O2 supply with O2 demand by causing vasodilatation. This review argues that adenosine plays a similar role in skeletal muscle in systemic hypox

The vasoactive substances adenosine and nitric oxide (NO) are credible candidates in the local regulation of skeletal muscle blood flow. Adenosine and NO have both been shown to increase in skeletal muscle cells and interstitial fluid during exercise

Abnormalities in dopamine (DA) and noradrenaline (NA) activities and sodium handling may be involved in the pathogenesis of hypertension. The present study was designed to investigate whether any differences exist between normotensive Wistar-Kyoto ra

UNLABELLED The mechanisms behind the vasodilatory effect of insulin are not fully understood, but nitric oxide plays an important role. We have investigated the possibility that insulin mediates vasodilatation in the human skeletal muscle via an incr
