The atrial natriuretic peptide (ANP), a member of the natriuretic peptide family, is a cardiovascular hormone which possesses well defined natriuretic, diuretic and vasodilating properties. Most of the biological effects of ANP are mediated through its guanylyl cyclase coupled receptor. ANP and its receptors have been shown to be expressed and differentially regulated in the immune system, and ...

BACKGROUND High levels of endogenous atrial natriuretic peptide (ANP) are thought to compensate the condition of patients with heart failure by reducing preload and afterload. However, recent reports have indicated that a high plasma ANP level is a prognostic predictor in patients with heart failure. Therefore, the role of endogenous ANP has not been clearly established in patients with heart f...

PURPOSE Atrial natriuretic peptide (ANP) is a known vascular antipermeability and antiangiogenic factor, but its possible alteration during the early stages of diabetic retinopathy has not yet been explored. The present study sought to investigate the expression of ANP and its receptors using a model of streptozotocin (STZ) induced diabetes in the rat. METHODS Diabetes was induced in male Wis...

The aim of the current study was to investigate the therapeutic effect of Tripterygium wilfordii Hook F multiglycosides (TWG) on gut barrier dysfunction in rats with acute necrotizing pancreatitis (ANP). ANP was induced in rats using 3.5% sodium taurocholate. The rats were divided into 3 groups: the sham operation (SO), ANP and ANP+TWG groups. Biochemical and pathological change of pancreatic t...

BACKGROUND Assessment of endocrine profile in patients with cardiovascular diseases has become increasingly important during the last decade. Plasma brain natriuretic peptide (BNP) levels have been used as a marker of left ventricular dysfunction. However, the role of BNP in patients with atrial fibrillation (AF) and normal left ventricular function has not yet been determined. AIM To examine...

INTRODUCTION Additional biomarkers in sepsis are needed to tackle the challenges of determining prognosis and optimizing selection of high-risk patients for application of therapy. In the present study, conducted in a cohort of medical intensive care unit patients, our aim was to compare the prognostic value of mid-regional pro-atrial natriuretic peptide (ANP) levels with those of other biomark...

BACKGROUND Cardiac dysfunction is seen in many patients and could be evaluated with echocardiography and serum biomarkers. The aim of this study was evaluation of the relationship between echocardiographic findings and laboratory serum biomarkers in children with and without low cardiac output. METHODS Thirty patients older than 1 month with and without low cardiac output were enrolled in thi...

BACKGROUND Atrial natriuretic peptide (ANP) was recently reported to ameliorate fibrosis in the heart and experimental renal diseases and vascular thickening after balloon injury. Peritoneal fibrosis is an important complication of long-term peritoneal dialysis, and peritonitis is a factor in its onset. In the present study, we investigated the effects of ANP in a rat peritonitis-induced perito...

Background. High levels of endogenous atrial natriuretic peptide (ANP) are thought to compensate the condition of patients with heart failure by reducing preload and afterload. However, recent reports have indicated that a high plasma ANP level is a prognostic predictor in patients with heart failure. Therefore, the role of endogenous ANP has not been clearly established in patients with heart ...

Atrial natriuretic peptide (ANP) acutely promotes water and sodium excretion, whereas subchronic effects involve water retention. Renal hemodynamics, water and sodium excretion, and aquaporin-2 (AQP2) and epithelial Na channel (ENaC) subcellular trafficking were determined in response to continuous ANP infusion in conscious rats, where body sodium and fluid balance was constantly maintained. AN...
