Modifications of atrial natriuretic peptide and vasopressin peptides in the rat hypothalamic supraoptic nucleus during resistance training.
Many studies have demonstrated the involvement of atrial natriuretic peptide (ANP) and vasopressin (VP) in the homeostasis of body fluids, but few studies have regarded the hypothalamic magnocellular neurosecretory system during physical exercises. The aim of the present immunohistochemical work is to study the activity of ANP and VP secreting neurons of the hypothalamic supraoptic nucleus duri...
متن کاملAtrial natriuretic peptide modulates synaptic transmission from osmoreceptor afferents to the supraoptic nucleus.
Atrial natriuretic peptide (ANP) and its receptors are present in hypothalamic nuclei containing the magnocellular neurosecretory cells (MNCs), which release vasopressin and oxytocin. In the rat, intracerebroventricular injections of ANP inhibit the release of both hormones in response to hypertonicity. Although these findings suggest a role for endogenous ANP in the central control of fluid ba...
متن کاملAtrial natriuretic peptide transcription, secretion, and glomerular receptor activity during mineralocorticoid escape in the rat.
The mechanisms that mediate renal "escape" from the sodium-retaining effects of mineralocorticoids are incompletely understood. This study was undertaken to determine whether atrial natriuretic peptide (ANP) may play a role in the escape phenomenon. Immunoreactive ANP in rat plasma increased 2.5-fold above baseline values at 12 and 24 h after a single depot injection of desoxycorticosterone ace...
متن کاملCellular mechanisms for synthesis and secretion of atrial natriuretic peptide and brain natriuretic peptide in cultured rat atrial cells.
To investigate the cellular mechanism for the synthesis and secretion of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP), we examined the effects of vasoactive agents on the secretion rates and gene expression of ANP and BNP in cultured rat atrial cells. Endothelin (10(-7) M, +61%), 12-O-tetradecanoylphorbol 13-acetate (TPA, 10(-6) M, +62%), the calcium ionophore A23187 (10...
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...
