Effects of ouabain on vascular reactivity
(1997-04)
Ouabain is an endogenous substance occurring in the plasma in the nanomolar range, that has been proposed to increase vascular resistance and induce hypertension. This substance acts on the a-subunit of Na+,K+-ATPase ...
Effects of central alpha-adrenergic agonists on hormone-induced 3% NaCl and water intake
(Elsevier B.V., 1996-08-23)
Male rats received intracerebroventricular (ICV) renin (600 ng) or daily subcutaneous injections of deoxycorticosterone (5 mg) to induce 3% NaCl and water intake. Noradrenaline (NOR; 40-160 nmol) and clonidine (CLO; 5-20 ...
Temperature effects on baroreflex control of heart rate in the toad, Rhinella schneideri
(2015)
For an adequate blood supply to support metabolic demands, vertebrates regulate blood pressure to maintain sufficient perfusion to avoid ischemia and other tissue damage like edema. Using a pharmacological approach ...
Chemoreflex and baroreflex alterations in Parkinsonism induced by 6-OHDA in unanesthetized rats
(Elsevier B. V., 2015-10-21)
Parkinson's disease (PD) is mainly characterized by motor signals. However, non-motor signals also affect and decrease the quality of life of PD patients. Among these non-motor signs are cardiovascular disorders as orthostatic ...
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 ...
Alpha1-adrenergic drugs affect the development and expression of ethanol-induced behavioral sensitization
(Elsevier B.V., 2013-11-01)
Background: According to the incentive sensitization theory, addiction is caused primarily by drug-induced sensitization in the brain mesocorticolimbic systems. After repeated ethanol administration, some animals develop ...
Sex chromosome complement contributes to sex differences in bradycardic baroreflex response
(Hypertension, 2011)
To investigate whether sex chromosome complement modulates bradycardic baroreflex response and contributes to the angiotensin II– bradycardic baroreflex sex differences, we used the four core genotype mouse model in which ...
