Sibjotang Increases Atrial Natriuretic Peptide Secretion in Beating Rabbit Atria
Sibjotang (Shizaotang), traditional herbal medicine formula, which was first documented in the Shanghanlun, has long been prescribed for the treatment of impairment of the body fluid homeostasis. The purpose of the present study was to identify the effects of Sibjotang on the secretion of a cardiac hormone, atrial natriuretic peptide (ANP), one of the main hormones involved in the regulation of...
متن کاملCharacterization of natriuretic peptide production by adult heart atria.
The cardiac polypeptide hormones atrial natriuretic factor (ANF) and brain natriuretic peptide (BNP) are synthesized and costored by atrial cardiocytes and share receptors and many biologic properties. Although some aspects of their synthesis and release are specific for each peptide, it is not clear whether they share intracellular sorting and secretory mechanisms. In the present work we take ...
متن کاملSecretion of atrial natriuretic peptide from the heart in man.
Plasma concentrations of atrial natriuretic peptide were measured in eight patients undergoing elective cardiac catheterisation and angiography. All patients had normal resting pressures in the cardiac chambers and no clinical evidence of heart failure. Plasma atrial natriuretic peptide rose significantly from the superior vena cava into the right atrium and right ventricle. The increase into t...
متن کاملPhospholipase C signaling tonically represses basal atrial natriuretic factor secretion from the atria of the heart.
The cardiac hormone atrial natriuretic factor (ANF or ANP) plays significant, well-established roles in a large number of physiological and pathophysiological processes, including water and electrolyte balance, blood pressure regulation, and cardiovascular growth. Understanding the regulation of its production and secretion by atrial cardiomyocytes is incomplete. We have previously established ...
متن کاملCalcium, its role in isoproterenol-stimulated atrial natriuretic peptide secretion by superfused rat atria.
The beta-adrenergic agonist isoproterenol stimulates immunoreactive atrial natriuretic peptide (IR-ANP) secretion by superfused rat atria in vitro. beta-Adrenergic agonists alter the cellular handling of calcium, which culminates in a rise in the systolic calcium concentration. This is achieved by increasing calcium influx through voltage-dependent calcium channels and by increasing the storage...
