BACKGROUND Endothelin is an extremely potent vasoconstrictor that may have a role in the pathogenesis of acute myocardial ischaemia. Atrial natriuretic factor is an endogenous antagonist of endothelin. To find the pattern and possible importance of circulating endothelin in ischaemic heart disease, concentrations in normal controls and those in patients with stable and unstable angina, acute my...
The human heart secretes both atrial natriuretic peptide and brain natriuretic peptide. This study attempts to clarify the pathophysiological significance of the peptides in cardiovascular diseases. Using immunoradiometric assay, plasma brain natriuretic peptide and atrial natriuretic peptide levels in essential hypertension, various secondary hypertension, chronic renal failure, chronic heart ...
The structure of atrial natriurtic peptide (ANP) and Brain natriuretic peptide (BNP) are similar and they are also similar in their actions e.g natriuresis and vasodilation. The previous studies have revealed the presence of ANP and BNP in sheep atrial extract, wherease ANP in human atrial. The aim of the present study is to investigate the comparison of hemodynamic effects of these two atrial ...

Synthetic atrial natriuretic factor (Arg-Arg-Ser-Ser-Cys-Phe-Gly-Gly-Arg-Ile-Asp-Arg-Ile-Gly-Ala-Gln-Ser-Gly -Leu- Gly-Cys-Asn-Ser-Phe-Arg-Tyr-COOH [disulfide bond between cysteines]) was infused intravenously into conscious normotensive and deoxycorticosterone, one-kidney, one-clip, and two-kidney, one-clip hypertensive rats. Mean arterial pressure, urine volume, and electrolyte excretion rate...
This study investigated whether excision of either the right or left atrial appendage of rats alters their natriuretic response and the release of atrial natriuretic factor during acute blood volume expansion or reduction. These animals were subjected to a thoracotomy and either had their right or left atrial appendages removed or underwent a right or left atrial sham appendectomy for comparati...
