Atrial wall stretching is a known stimulus for atrial natriuretic peptide (ANP) secretion. The effects of the stimulation of autonomic nervous system, hemodynamic factors, and humoral factors (epinephrine, angiotensin, vasopressin, and brain extracts) on the release of ANP under basal conditions and during increased atrial pressure produced by acute volume loading in pithed rats were examined. ...
To explore whether pathophysiological plasma levels of atrial natriuretic peptide (ANP) actually involve sodium excretion in spontaneously hypertensive rats (SHR), we examined the in vivo and ex vivo effects of ANP and an endopeptidase inhibitor, thiorphan, on urinary sodium excretion and the elimination rate of ANP. We found the following: 1) The basal plasma ANP level was higher in 16-week-ol...
Atrial natriuretic peptide and mechanisms of cardiovascular control. Role of serotonergic receptors.
Atrial natriuretic peptide (ANP) inhibits renal sympathetic nerve activity (RSNA), provided the vagi are intact. Afferents from chemosensitive cardiopulmonary receptors are specifically required. Such receptors produce the Bezold-Jarisch reflex, are prominent on the ventricular epicardium, and are richly supplied with 5-hydroxytryptamine type 3 (5-HT3) receptors. We tested the hypothesis that e...
The border regions (periphery) are far away from the center due to remoteness, geographical isolation, lack of development, and ... great differences in terms of prosperity and development with central centers. Creating and operating a border market can modify the one-way central- Around and improve regional prosperity. The purpose of this study was to investigate the role of the border market...
A new insofar as chronobiologic therapeutic approach by atrial natriuretic peptide (ANP) for hypertension and/or congestive heart failure (CHF) is based on the release of ANP from ANP cDNA transfected Chinese Hamster Ovary (CHO) cells encapsulated in polycaprolactone (PCL) tubes. ANP secretion was maintained for at least 6 months. The encapsulated cells remained viable during culturing. Control...
Leptin is a circulating adipocyte-derived hormone that influences blood pressure (BP) and metabolism. This study was designed to define the possible role of leptin in regulation of the atrial natriuretic peptide (ANP) system using acute and chronic experiments. Intravenous infusion of rat leptin (250 microg/kg injection plus 2 microg.kg(-1).min(-1) for 20 min) into Sprague-Dawley rats increased...
BACKGROUND Plasma levels of atrial and brain natriuretic peptides (ANP and BNP) are increased in patients with chronic kidney disease (CKD) complicated with deteriorated kidney function, but the relationship between the plasma level of ANP or BNP and the future development of CKD is unclear. METHODS We measured the plasma ANP and BNP levels of 294 local residents without CKD in a Japanese com...
Atrial natriuretic peptide (ANP)-preconditioned livers are protected from ischemia-reperfusion injury. ANP-treated organs show increased expression of heme oxygenase (HO)-1. Because HO-1 liberates bound iron, the aim of our study was to determine whether ANP affects iron regulatory protein (IRP) activity and, thus, the levels of ferritin. Rat livers were perfused with Krebs-Henseleit buffer [+/...
