Hypoxic contraction of isolated canine coronary artery. Mediation by potassium-dependent exocytosis of norepinephrine.
Effects of hypoxia on arterial tone, efflux of potassium, and efflux of norepinephrine were monitored for isolated canine coronary arteries labeled with radioactive potassium (42K) and norepinephrine (3HNE). Hypoxia elicited transient relaxation and subsequent sustained contraction accompanied by marked increases in the effluxes of 42K and 3HNE. After sympathetic nerve injury with 6-hydroxydopa...

متن کاملDevelopment of endothelium-dependent relaxation in canine coronary collateral arteries.
BACKGROUND Little information exists regarding development of vasomotor control mechanisms during coronary collateral artery maturation. Therefore, we studied endothelium-dependent relaxation of canine collateral arteries isolated 2, 4, and 9 months after placement of an ameroid occluder around the proximal left circumflex coronary artery. RESULTS Collateral arteries isolated after 2 months e...

متن کاملVascular effects of 15-hydroperoxyeicosatetraenoic acid and 15-hydroxyeicosatetraenoic acid on canine arteries.
The vascular effects of 15-hydroperoxyeicosatetraenoic acid (15-HPETE) and 15-hydroxyeicosatetraenoic acid (15-HETE) were investigated on isolated helical strips of canine cerebral and coronary arteries. 15-HPETE caused strong concentration-related contraction of cerebral arteries under resting tension. After contraction with prostaglandin F2 alpha (PGF2 alpha), 15-HPETE caused marked relaxatio...
متن کاملPositive chronotropic and negative inotropic effects induced by potassium chloride in the isolated canine atrium.
The effects of potassium chloride on inotropic and chronotropic activity were investigated in five isolated canine atrium preparations which were suspended in a bath and perfused with arterial blood from the carotid artery of the heparinized support dog. Potassium chloride administered into the cannulated sinus node artery in a dose range of 100 mug-1 mg produced a dose-related negative inotrop...
