Antihypertensive responses elicited by central moxonidine in rats: Possible role of nitric oxide
(Journal of Cardiovascular Pharmacology, 2006-06-01) [Artigo]
In the present study, we investigated the effects of pretreatment with N-G-nitro-L-arginine methyl ester (L-NAME) (nitric oxide synthase inhibitor) injected intravenously (IV) on the hypotension, bradycardia, and vasodilation ...

Moreira TS, Takakura AC, Colombari E, Menani JV. Antihypertensive effects of central ablations in spontaneously hypertensive rats. Am J Physiol Regul Integr Comp Physiol 296: R1797-R1806, 2009. First published April 1, ...
Inhibition of central angiotensin II-induced pressor responses by hydrogen peroxide
(Neuroscience, 2010-12-01) [Artigo]
Hydrogen peroxide (H(2)O(2)) important reactive oxygen species produced endogenously, may have different physiological actions The superoxide anion (O(2)(-)) is suggested to be part of the signaling mechanisms activated ...
Central nitric oxide modulates hindquarter vasodilation elicited by AMPA receptor stimulation in the NTS of conscious rats
(American Journal of Physiology: Regulatory Integrative and Comparative Physiology, 2006-05-01) [Artigo]
Microinjection of S-α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) in the nucleus of the solitary tract (NTS) of conscious rats causes hypertension, bradycardia, and vasoconstriction in the renal, mesenteric, ...
A1 Noradrenergic Neurons Lesions Reduce Natriuresis and Hypertensive Responses to Hypernatremia in Rats
(PLOS ONE, 2013-09-10) [Artigo]
Noradrenergic neurons in the caudal ventrolateral medulla (CVLM; A1 group) contribute to cardiovascular regulation. The present study assessed whether specific lesions in the A1 group altered the cardiovascular responses ...
Is carotid body input the only critical mechanism involved in hypertension in spontaneously hypertensive rat?
(Journal of Physiology, 2013-02-01) [Carta]
Importância da região anteroventral do terceiro ventrículo (AV3V) no controle cardiovascular e do equilíbrio hidroeletrolítico
(Medicina, 2006-01-01) [Trabalho apresentado em evento]
The maintenance of the arterial pressure in normal levels is important for the homeostasis of body fluids. The central nervous system regulating sympathetic and parasympathetic autonomic efferent can adjust arterial pressure ...
Macrophage migration inhibitory factor in the nucleus of solitary tract decreases blood pressure in SHRs
(Cardiovascular Research, 2013-01-01) [Artigo]
Aims The macrophage migration inhibitory factor (MIF) is an intracellular inhibitor of the central nervous system actions of angiotensin II on blood pressure. Considering that angiotensin II actions at the nucleus of the ...
Effects of AV3V lesion on pilocarpine-induced pressor response and salivary gland vasodilation
(Brain Research, 2005-09-07) [Artigo]
The cholinergic agonist pilocarpine injected intraperitoneally (ip) increases mean arterial pressure (MAP) and superior mesenteric (SM) vascular resistance and reduces submandibular/sublingual gland (SSG) vascular resistance. ...
Cardiovascular responses to microinjection of L-glutamate into the NTS in AV3V-lesioned rats
(Brain Research, 2004-10-29) [Artigo]
The excitatory amino acid L-glutamate injected into the nucleus of the solitary tract (NTS) in unanesthetized rats similar to peripheral chemoreceptor activation increases mean arterial pressure (MAP) and reduces heart ...
