Cerebral vasoconstriction produced by vasopressin in conscious goats: role of vasopressin V1 and V2 receptors and nitric oxide To examine the role of vasopressin V 1 and V 2 receptors, nitric oxide and prostanoids in the cerebrovascular effects of arginine vasopressin, cerebral b... N Fernández,...
Renal hypoxia and the subsequent generation of reactive oxygen species, vasoconstriction, and inflammation have all been reported to play a central role in the pathogenesis of CIN [5]. Previous studies have also indicated that inflammatory cells and cytokines are involved in the mechanisms of CIN [...
Vasospasms are mainly drug-induced: digoxin, phenylephrine, vasopressin, calcium channel blockers, amphetamines, or cocaine [3]. Other situations when blood flow is routed away from the intestines, leading to ischemia, include increased intraabdominal pressure (extrinsic compression of intestinal ...
t-PA release is stimulated in vivo by norepinephrine, vasopressin or stasis within the vessel lumen. Thrombin may also stimulate t-PA release, providing a further endothelium-mediated safeguard against uncontrolled coagulation. 1.2. Regulation of vascular tone. The central role of the endothelium in ...
(c) How vasopressin can regulate blood flow? What is meant by a closed circulatory system? Choose the correct answer: The prevention of blood loss is called A) homeostasis B) hemostasis C) vascularization D) transfusion What is the process of filtering blood periodically th...
vasopressin1There is considerable in vitro evidence that, at high concentrations, atrial natriuretic peptide (ANP) acts directly on pre-constricted blood vessels to cause vasorelaxation. Previously, we have seen vasoconstriction rather than vasodilatation in conscious dogs at physiological levels of the ...
How does vasopressin hormones work in regulating blood pressure? How does the body regulate blood pressure? Explain the role of aldosterone in decreasing the blood pressure. How does blood pressure promote filtration of blood in the kidneys? How does blood pressure affect the kidneys? How does ald...
