Cardiovascular effects of noradrenaline microinjected into the insular cortex of unanesthetized rats
(Elsevier B.V., 2011-02-24)
The insular cortex (IC) has been reported to be involved in central cardiovascular control. In the present study, we investigated the cardiovascular responses evoked by microinjection of noradrenaline into the IC as well ...
Inhibitory effect of DUP-753 on the drinking responses of rats to central administration of noradrenaline and angiotensin II and to dehydration
(Associação Brasileira de Divulgação Científica (ABRADIC), 1996-04-01)
We investigated the effect of losartan (DUP-753) on the dipsogenic responses produced by intracerebroventricular (icv) injection of noradrenaline (40 nmol/mu l) and angiotensin II (ANG II) (2 ng/mu l) in male Holtzman rats ...
Facilitation of sodium intake by combining noradrenaline into the lateral parabrachial nucleus with prazosin peripherally
(2013-10-01)
Injections of noradrenaline into the lateral parabrachial nucleus (LPBN) increase arterial pressure and 1.8% NaCl intake and decrease water intake in rats treated with the diuretic furosemide (FURO) combined with a low ...
Effect of intracerebroventricular injection of ramipril on the drinking response caused by injection of noradrenaline into the third ventricle
(Associação Brasileira de Divulgação Científica (ABRADIC), 1996-11-01)
We studied the effect of ramipril injected into the third ventricle (3rdV) on the control of water intake induced by injection of noradrenaline into the 3rdV of adult male Holtzman rats (250-300 g) implanted with a chronic ...
Interaction between brain L-type calcium channels and alpha(2)-adrenoceptors in the inhibition of sodium appetite
(Elsevier B.V., 2002-03-22)
Calcium channels mediate the actions of many drugs. The present work investigated whether diltiazem, an L-type calcium channel blocker, alters the inhibition of sodium appetite induced by noradrenaline and the alpha(2)-a ...
Inhibition of pilocarpine-induced salivation in rats by central noradrenaline
(Elsevier B.V., 2002-06-01)
Peripheral treatment with cholinergic or adrenergic agonists results in salivation and the possibility of synergy between cholinergic and adrenergic efferent mechanisms in the control of salivation has been proposed. Central ...
EFFECT OF LATERAL HYPOTHALAMUS LESIONS ON THE WATER AND SALT INTAKE, AND SODIUM AND URINE EXCRETION INDUCED BY ACTIVATION OF THE MEDIAN PREOPTIC NUCLEUS IN CONSCIOUS RATS
(Elsevier B.V., 1995-06-25)
In this-study we investigated the influence of electrolytic lesion of the lateral hypothalamus (LH) on the water and salt appetite, and the natriuretic, diuretic and cardiovascular effects induced by angiotensinergic, ...
Urinary levels of catecholamines among individuals with and without sleep bruxism
(Springer Heidelberg, 2009-02-01)
Sleep bruxism (SB) is characterized by repetitive and coordinated mandible movements and non-functional teeth contacts during sleep time. Although the etiology of SB is controversial, the literature converges on its ...
Functional characterisation of alpha(1)-adrenoceptors in denervated rat vas deferens
(Springer, 2003-07-01)
We investigated whether or not surgical denervation of the rat vas deferens changes the alpha(1)-adrenoceptor subtypes involved in the contractions to noradrenaline. Denervated vas deferens was approximate to22 times more ...
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 ...
