Effect of adrenergic stimulation of the amygdaloid complex on water intake
(1996-12-01)
The effect of noradrenaline, isoproterenol, phentolamine and propranolol, injected into the basolateral nuclei of the amygdala on water intake, was investigated in male Holtzman rats. The injection of noradrenaline (40 ...
Role of noradrenaline on the expression of the Na+/K+-ATPase alpha(2) isoform and the contractility of cultured rat vas deferens
(Elsevier B.V., 2002-11-15)
Rat vasa deferentia were cultured for 3 days in Dulbecco's modified Eagle's medium in the absence or presence of 1 muM noradrenaline (NA) to investigate if the lack of NA release is the key factor to explain the selective ...
Stress-induced subsensitivity to catecholamines depends on the estrous cycle
(Natl Research Council Canada, 1996-06-01)
In this article we compare how sensitivity to the chronotropic effect of noradrenaline and adrenaline of right atria isolated from female rats is modified after repeated swimming or foot-shock stress, under the influence ...
Adrenergic mechanisms of the Kölliker-Fuse/A7 area on the control of water and sodium intake
(Pergamon-Elsevier B.V. Ltd, 2009-12-01)
The blockade of serotoninergic receptors with methysergide or the activation of alpha(2)-adrenoceptors with moxonidine into the lateral parabrachial nucleus (LPBN) increases water and 0.3 M NaCl intake in rats treated with ...
Noradrenaline and mixed alpha(2)-adrenoceptor/imidazoline-receptor ligands: effects on sodium intake
(Elsevier B.V., 1999-08-28)
The effect of noradrenaline, and mixed ligands to alpha(2)-adrenoceptors (alpha(2)-AR) and imidazoline receptors (IR), injected intracerebroventricularly (i.c.v.), on sodium intake of sodium depleted rats, was tested against ...
Influence of the estrous cycle on the sensitivity to catecholamines in right atria from rats submitted to foot-shock stress
(1996-11-23)
We investigated the mechanisms of the alterations in sensitivity to catecholamines in right atria from female rats exhibiting regular 4-day estrous cycles after three foot-shock sessions at estrus, metestrus, and diestrus ...
