Atrial natriuretic factor in hypovolemic tachycardia
Experientia, 1987Atrial natriuretic factor (ANF) is released in response to many stimuli which increase right atrial pressure. Following hemorrhage pigs lowered their atrial pressures, developed a tachycardia and increased ANF levels. Electrical pacing increased heart rate and ANF levels. There is a stimulus to ANF release other than atrial stretch, probably heart rate.

Atrial natriuretic factor is a circulating hormone
Biochemical and Biophysical Research Communications, 1984The radioimmunoassay of atrial natriuretic factor (ANF) has been applied for determination of immunoreactive ANF (IR-ANF) in rat plasma. Immunoreactive ANF has been extracted from rat plasma by immunoaffinity column on Sepharose-4B anti-ANF or by Vycor glass. The mean concentrations of IR-ANF in ether anesthetized rats were found to be 1.61 +/- 0.14 ng/

Atrial Natriuretic Factor: A Historic Perspective
The American Journal of the Medical Sciences, 1987Atrial natriuretic factor (ANF) is a relatively newly discovered hormone. Its discovery was the culmination of almost a half century of research. This article reviews some of the data leading up to its discovery. In addition, the issue of its physiologic role in volume expansion is considered.

Atrial natriuretic factor in essential hypertension
Life Sciences, 1989We measured circulating levels of immunoreactive atrial natriuretic factor (ANF) in 10 patients with untreated, uncomplicated mild to moderate essential hypertension and in 15 normotensive controls. ANF concentrations were significantly higher in the hypertensive group than in the control group (38.4 +/- 6.9 pg/ml versus 18.3 +/- 1.8 pg/ml, p less than

Atrial natriuretic factors and the brain: an update
Trends in Neurosciences, 1988Abstract The heart is an endocrine organ. The atria synthesize and release into the bloodstream a family of peptides known as atrial natriuretic factors (ANF). ANF-like peptides act on various target tissues such as blood vessels, adrenals and kidneys to regulate homeostasis.

Atrial Natriuretic Factors and Fragments
1993Publisher Summary Atrial natriuretic factor (ANF) or atrial natriuretic peptide (ANP) consists of mixtures of peptides of various lengths. Studies have shown that the circulating form of ANF in plasma consists of a 28-amino acid residue ANF (ANP), whereas the rat and human atrium largely stores pro-ANF (γ-ANP), containing 126 amino acid residues ...

Atrial Natriuretic Factor as a Volume Regulator
The Journal of Clinical Pharmacology, 1994Atrial natriuretic factor, originally isolated from the atrium of the heart, has been found to consist of three major groups: atrial natriuretic peptide (ANP), B‐form natriuretic peptide (BNP), and C‐form natriuretic peptide (CNP). In addition, ANP exists in its precursor form, pro‐ANP, an active ANP with a longer peptide chain (urodilatin) and an ...

[The physiopathological aspects of the atrial natriuretic factor].
Minerva medica, 1992The original observation by de Bold et al. (1981) of a rapid, massive, and short-lasting diuretic and natriuretic effect following injection of rat atrial extracts into intact rats, led to the identification, isolation and purification of the atrial natriuretic factor (ANF).
