...Vitalij M. Rudichenko; William H. Beierwaltes The vasconstrictor vasopressin has been reported to induce paradoxical local vasodilation in the basilar vasculature through stimulation of the endothelium-derived relaxing factor nitric oxide (NO). We investigated the possibility that at subpressor...

...Eric Dumont; Daniel Lamontagne The contribution of ATP-sensitive potassium channel (K ATP channel) blockade in the vasoconstriction produced by vasopressin was studied. All experiments were performed using rat thoracic aorta cut in 4-mm rings, denuded from their endothelium and mounted into 20-ml...

...K. Dylewska; J.G. Widdicombe Desmopressin and vasopressin were injected into the blood supply of the bilaterally perfused nasal mucosa of the dog. Nasal vascular resistance and, in some experiments, nasal airflow resistance and the secretory output of the lateral nasal gland were measured on both...

...F.M. Abboud; J.S. Floras; P.E. Aylward; G.B. Guo; B.N. Gupta; P.G. Schmid At low concentrations and in physiologic states vasopressin is a potent antidiuretic hormone. Its cardiovascular effects have been more complex and their role in circulatory adjustments to hypovolemia and hypotension...

... in isolated vascular tissue have been minimally successful at best. The present study reports that bovine PTH-(1–34) can relax isolated rat tail artery helical strips precontracted by either arginine vasopressin, depolarizing concentrations of potassium chloride, or norepinephrine. The phenomenon occurs...

...George Mchedlishvili; Leila Ormotsadze In order to study the action of serotonin (5-HT), noradrenaline (NA), hypertensin (HT), prostaglandins A 1, B 1 and E 2 (PGA 1, PGB 1 and PGE 2 ) and vasopressin (VP), internal carotid arteries were isolated in situ from both cerebral and general circulation...

...George Wyse Responses to exogenous norepinephrine (NE), transmural electrical stimulation, 5-hydroxytryρtamine (5-HT) and lysine vasopressin were studied in isolated helical strips of the small artery and vein from the mesoappendix of patients undergoing incidental appendectomy at the time...

...A.H. Weston; K. Golenhofen Angiotensin produced inhibitory and excitatory responses in guinea pig portal vein and excitatory responses in rabbit and rat portal vein. Vasopressin produced inhibitory responses in guinea pig and rabbit portal vein and excitatory and inhibitory responses in rat portal...
