Angiotensin inhibition and atrial natriuretic peptide release after acute volume expansion in rats with aortocaval shunt.
OBJECTIVE In heart failure atrial natriuretic peptide (ANP) release in response to volume expansion is impaired while the renin-angiotensin system is activated. This study was designed to test the hypothesis that ANP release in heart failure is dependent on an activated angiotensin system. METHODS We studied the ANP and renin-angiotensin systems in a rat model of shunt-induced high-output hea...
متن کاملOxytocin mediates atrial natriuretic peptide release and natriuresis after volume expansion in the rat.
Our previous studies have shown that stimulation of the anterior ventral third ventricular region increases atrial natriuretic peptide (ANP) release, whereas lesions of this structure, the median eminence, or removal of the neural lobe of the pituitary block ANP release induced by blood volume expansion (BVE). These results indicate that participation of the central nervous system is crucial in...
متن کاملCarotid-aortic and renal baroreceptors mediate the atrial natriuretic peptide release induced by blood volume expansion.
Our previous studies have shown that stimulation of the anteroventral third ventricle (AV3V) region of the brain increases atrial natriuretic peptide (ANP) release, whereas lesions of the AV3V region or median eminence of the tuber cinereum block the release of ANP caused by blood volume expansion. These results suggest that participation of the central nervous system is critical to this respon...
متن کاملEvaluation of Serum Levels of N-terminal Pro Brain Natriuretic Peptide and Atrial Natriuretic Peptide in Neonates with Respiratory Distress
Background: Acute respiratory distress (ARD) is a critical respiratory failure due to lung injury of neonates leading to the clinical appearance of poor lung compliance. The aimed of the study was to evaluate the diagnostic values in differentiating respiratory from heart diseases with using of N-terminal pro brain natriuretic peptide (NT-pro BNP) and Atrial natriuretic peptide(ANP) in neonates...
متن کاملBradykinin does not modulate the natriuretic response to atrial natriuretic factor in rats with aortocaval fistula.
Rats with aortocaval fistula, an experimental model of congestive heart failure (CHF), display two distinct patterns of sodium excretion: some rats develop marked sodium retention and worsening edema with urinary excretion of sodium (UNaV) < 200 microEq per 24 hours, i.e., uncompensated CHF, whereas in others sodium balance rapidly returns to normal (UNaV > 1,400 microEq per 24 hours), i.e., co...
