Sidestream cigarette smoke effects on cardiovascular responses in conscious rats: involvement of oxidative stress in the fourth cerebral ventricle
(Biomed Central Ltd., 2012-03-30)
Background: Cigarette exposure increases brain oxidative stress. The literature showed that increased brain oxidative stress affects cardiovascular regulation. However, no previous study investigated the involvement of ...

Role of the Carotid Bodies in the Hypertensive and Natriuretic Responses to NaCl Load in Conscious Rats
(Frontiers Media Sa, 2018-12-04)
Hyperosmotic challenges trigger a hypertensive response and natriuresis mediated by central and peripheral sensors. Here, we evaluated the importance of the carotid bodies for the hypertensive and natriuretic responses to ...
Sympathetic activation in rats with L-NAME-induced hypertension
(Associação Brasileira de Divulgação Científica, 2007-03-01)
We evaluated the hemodynamic pattern and the contribution of the sympathetic nervous system in conscious and anesthetized (1.4 g/kg urethane, iv) Wistar rats with L-NAME-induced hypertension (20 mg/kg daily). The basal ...
Antinociception induced by epidural motor cortex stimulation in naive conscious rats is mediated by the opioid system
(ELSEVIER SCIENCE BV, 2009)
Epidural motor cortex stimulation (MCS) has been used for treating patients with neuropathic pain resistant to other therapeutic approaches. Experimental evidence suggests that the motor cortex is also involved in the ...
Hemodynamic effects elicited by microinjection of glutamatergic agonists into NTS of conscious rats
(Amer Physiological Soc, 2001-09-01)
In this study, we characterized the arterial pressure, heart rate, and regional vascular conductance responses elicited by unilateral microinjection of ionotropic glutamatergic agonists N-methyl-D-aspartic acid (NMDA and ...
Differential roles of hippocampal nNOS and iNOS in the control of baroreflex function in conscious rats
(2019-05-01)
The baroreflex is a prominent moment-to-moment mechanism regulating the blood pressure. The hippocampus is a limbic structure in which has been pointed out as part of central network regulating baroreflex. However, the ...
Impaired dipsogenic and renal response to repetitive intracerebroventricular angiotensin II (AngII) injections in rats
(Sage Publications LtdLondonInglaterra, 2011)
CARDIOVASCULAR EFFECTS OF CENTRAL CLONIDINE IN CONSCIOUS RATS AFTER HYPOTHALAMIC-LESIONS
(Elsevier B.V., 2014)
ATZ (3-amino-1,2,4-triazole) injected into the fourth cerebral ventricle influences the Bezold-Jarisch reflex in conscious rats
(Faculdade de Medicina / USP, 2010-01-01)
OBJECTIVES: Many studies have investigated the importance of oxidative stress on the cardiovascular system. In this study we evaluated the effects of central catalase inhibition on cardiopulmonary reflex in conscious Wistar ...
