Atrial Natriuretic Peptide in Infants and Children
Hormone Research, 1987Atrial natriuretic peptide (ANP) was measured in the plasma of 192 normal infants and children aged 1 day to 18 years. Plasma ANP was high during postnatal adaptation, particularly in premature infants. In 96 infants and children aged 4 months to 18 years, plasma ANP was similar to values obtained in 7 healthy adult volunteers (23.9 +/- 11.9 vs. 25.7 +/

Atrial Natriuretic Peptide in the Preterm Newborn
Neonatology, 1994Atrial natriuretic peptide (ANP), plasma renin and renin substrate concentrations (PRC and PRS) were measured in 31 preterm infants with idiopathic respiratory distress syndrome. Infants were studied at a mean of 1.4 days; 17 infants were also studied 2 days later.

Atrial natriuretic peptide in human hypertension
European Heart Journal, 1987Preliminary reports are that plasma levels of immunoreactive atrial natriuretic peptide (IR-ANP) are higher in essential hypertensive patients than in normotensive controls, and that the urinary response to injected alpha human atrial natriuretic peptide (alpha-hANP) is augmented in essential hypertension.

Atrial Natriuretic Peptide and Atrial Size
1989Enlarged plasma volume causes an increase of atrial size, and leads to a higher wall tension playing an important role in the secretion of ANP. Dependent on the compliance of the atrial myocardium different pressures may occur. Therefore it is likely that an atrial dilation — but not necessarily the increase of the atrial pressure — resulted in an ...

Degradation of atrial natriuretic peptide in dogs
Acta Endocrinologica, 1989Abstract. To clarify the degradation of atrial natriuretic peptide (ANP) in dogs, plasma ANP concentrations in blood samples drawn from the coronary sinus, and in simultaneously collected blood samples of the arteries and veins of the lung, liver, kidney, spleen and cervix, and of the supramesenteric artery and the portal vein, were measured, both when

Atrial Natriuretic Peptides in Antarctic Fish
1998Atrial natriuretic factors (ANFs) belong to a family of peptides originally described in mammalian heart. Beside ANPs, two other different types of natriuretic peptides with high sequence similarity have been identified, B-type natriuretic peptide (BNP) in the heart of chicken and mammals, and C-type natriuretic peptide (CNP) in the brain [1].

The Biochemistry of Atrial Natriuretic Peptides
1997It is now some 15 yr since de Bold and Sonnenberg and colleagues discovered that the injection of atrial extracts into rats gave rise to a profound diuresis, natriuresis, and hypotension (1). Within a very short time following this discovery it was shown that the agent responsible for this effect was a 28-amino acid, disulfide-bonded peptide that was ...

Radioimmunoassay of Atrial Natriuretic Peptide
1991Publisher Summary This chapter describes radioimmunoassay (RIA) of atrial natriuretic peptide (APN). Extracts of atrial tissue have been shown to exert a potent natriuretic and diuretic effect activity. The main difference between atrial and ventricular cardiocytes is the presence in the former of specific granules with morphological characteristic ...
