BACKGROUND In normal, conscious dogs, systemic injection of adenosine causes arterial hypotension and a baroreceptor reflex tachycardia mediated in part by withdrawal of vagal tone from the sinoatrial node. After vagal section or muscarinic receptor

Coronary vascular resistance may be regulated in part by substances whose concentrations are determined by or reflect the rate of myocardial oxygen consumption (e.g., adenosine, vessel wall PO2). We tested this hypothesis by comparing the time course

We tested the hypothesis that the endothelium-dependent relaxation of rabbit thoracic aorta in vitro is mediated by reduced metabolites of oxygen. Helical vascular strips were contracted with either norepinephrine or phenylephrine. Oxygen metabolites

Xanthine oxidase-derived oxygen metabolites caused a selective loss of norepinephrine-induced contractile tension in rings and helical strips from rabbit aorta. Phenylephrine-induced tension was not affected. The relaxation was selectively and comple

We tested the hypothesis that arachidonic acid metabolites mediate the coronary vascular response to changes in cardiac activity. Isoproterenol was administered intravenously to five chloralose-anesthetized, open-chest dogs. Left anterior descending

Adenosine and related compounds can produce atrioventricular (A-V) conduction block. Similar conduction disturbances are observed in myocardial hypoxia. To investigate the possibility that adenosine might be causally involved in hypoxic conduction di

Relative effects of equihypotensive doses (-35 mmHg) of adenosine (5.0 mumol/kg) and nitroglycerin (25 micrograms/kg) on heart rate and, therefore, baroreflex sensitivity were studied in conscious dogs. Nitroglycerin increased heart rate 133 +/- 24%

Coronary blood flow rate (ml.min/sup -1/.100 g/sup -1/) was estimated by (a) measuring pump flow into the cannulated circumflex branch of the left coronary artery and dividing by the weight of perfused mycardium and (b) measuring the clearance of /su
