Abstract:Heterozygous Brattleboro (HZ) rats exhibit a partial genetic deficiency in hypothalamic vasopressin (VP) production. The effects of this abnormality of HZ rats on the capacities of VP-neurons and oxytocin (OT)-neurons to respond to an acute salt-load were examined. Acute salt-loading was induced by intravenous infusion of 18% saline in conscious, chronically catheterized animals and the activities of VP-neurons and OT-neurons were interpreted from plasma concentrations of VP-associated neurophysin, [VP-RNP] an… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
