Cardiovascular effects of noradrenaline microinjected into the insular cortex of unanesthetized rats
(Autonomic Neuroscience-basic & Clinical, 2011-02-24) [Artigo]
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 ...
Bed nucleus of the stria terminalis alpha(1) and alpha(2) adrenoceptors differentially modulate the cardiovascular responses to exercise in rats
(Neuroscience, 2011-03-17) [Artigo]
Dynamic exercise evokes sustained blood pressure and heart rate (HR) increases. Although it is well accepted that there is a CNS mediation of cardiovascular adjustments during dynamic exercise, information on the role of ...
The semi-synthetic kaurane ent-16 alpha-methoxykauran-19-oic acid induces vascular relaxation and hypotension in rats
(European Journal of Pharmacology, 2011-06-25) [Artigo]
The present work investigates the mechanisms involved in the vasorelaxant effect of ent-16 alpha-methoxykauran-19-oic acid (KA-OCH(3)), a semi-synthetic derivative obtained from the kaurane-type diterpene ent-kaur-16-en-19-oic ...
Hypothalamic supraoptic but not paraventricular nucleus is involved in cardiovascular responses to carbachol microinjected into the bed nucleus of stria terminalis of unanesthetized rats
(Brain Research, 2011-06-01) [Artigo]
Microinjection of the cholinergic agonist carbachol into the bed nucleus of the stria terminalis (BST) has been reported to cause pressor response in unanesthetized rats, which was shown to be mediated by an acute release ...
Chronic fluoxetine treatment alters cardiovascular functions in unanesthetized rats
(European Journal of Pharmacology, 2011-11-30) [Artigo]
In the present study, we investigated the effects induced by fluoxetine treatment (10 mg/kg) for either 1 or 21 consecutive days on arterial pressure and heart rate basal levels, baroreflex activity, hemodynamic responses ...
