Multifactorial control of water and saline intake: Role of α2-adrenoceptors
(1997-04-01)
Water and saline intake is controlled by several mechanisms activated during dehydration. Some mechanisms, such as the production of angiotensin II and unloading of cardiovascular receptors, activate both behaviors, while ...
Multifactorial control of water and saline intake: Role of α2-adrenoceptors
(1997-04-01)
Water and saline intake is controlled by several mechanisms activated during dehydration. Some mechanisms, such as the production of angiotensin II and unloading of cardiovascular receptors, activate both behaviors, while ...
Clonidine and phenylephrine injected into the lateral preoptic area reduce water intake in dehydrated rats
(Elsevier B.V., 1993-09-01)
In the present study, we investigated the effect of phenylephrine and clonidine (α1- and α2-adrenoceptor agonists, respectively) injected into the lateral preoptic area (LPOA) on the water intake induced by water deprivation ...
Efeitos da clonidina nas respostas cardiovasculares ao pinçamento aórtico infra-renal. Estudo experimental no cão
(2003-09-01)
BACKGROUND AND OBJECTIVES: Infrarenal aortic cross-clamping is associated to cardiovascular effects. Clonidine, an α2-agonist, determines bradycardia and hypotension. This study aimed at analyzing the effects of clonidine ...
Role of cholinergic and adrenergic pathways of the medial septal area in the control of water intake and renal excretion in rats
(Elsevier B.V., 1992-05-01)
In this study, we investigated an interaction between noradrenergic and cholinergic pathways of the medial septal area (MSA) on the control of water intake and urinary electrolyte excretion by means of injection of their ...
Role of the alfa1- and alfa2-adrenoceptors of the lateral hypothalamus in the dipsogenic response to central angiotensin II in rats
(Elsevier B.V., 1991-09-27)
The present experiments were conducted to investigate the role of the α1- and α2-adrenergic receptors of the lateral hypothalamus (LH) on the drinking response elicited by intracerebroventricular (i.c.v) injections of ...
Role of central α1- and α2-adrenoceptors on the dipsogenic and cardiovascular effect of angiotensin II
(Elsevier B.V., 1990-08-01)
We investigated the effects of previous central treatment with prazosin (an α1-adrenoceptor antagonist) or clonidine (an α2-adrenoceptor agonist) on the dipsogenic, pressor and tachycardic responses produced by ...
