Atrial Natriuretic Factor in Untreated Hyperthyroidism
Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 1990Increased plasma concentration of atrial natriuretic factor (ANF) in untreated hyperthyroid patients is reported. A significant positive correlation between the concentration of ANF and serum thyroid hormones (T4 and T3) has been found when hyperthyroid patients and healthy controls were pooled together.

Renal response to atrial natriuretic factor in conscious dogs with caval constriction.
American Journal of Physiology, 1985Constriction of the thoracic inferior vena cava to decrease venous return and atrial filling markedly elevates plasma renin activity (PRA) and plasma aldosterone concentration (PAC) and produces chronic sodium retention and ascites in the dog.

Renal Effects Of Atrial Natriuretic Factor
Annual Review of Physiology, 1990A prominent effect of atrial natriuretic factor (ANF), indeed that for which it is named, is the ability to effect a solute and water diuresis. The renal mechanisms responsible for this natriuresis and diuresis have been subjects of intensive inquiry since the hormone's discovery in 1981.

Atrial natriuretic factor in human plasma
Biochemical and Biophysical Research Communications, 1986A reproducible and sensitive radioimmunoassay (RIA) was developed to measure ANF in human plasma. Immunoreactive ANF was extracted from plasma with Sep-Pak cartridges, using 0.2% ammonium acetate (pH 4) with acetonitrile. The sensitivity of the assay was 3.9 pg/ml.

Atrial Natriuretic Factor In Edematous Disorders
Annual Review of Medicine, 1990This article provides a brief overview of atrial natriuretic factor (ANF). Considered by many investigators to be the putative "third factor" governing sodium excretion, ANF is a peptide actively secreted by the heart, with multiple target organ effectors. As such, ANF represents the first clearly documented cardiac hormone.

Human Studies with Atrial Natriuretic Factor
Endocrinology and Metabolism Clinics of North America, 1987The human heart secretes ANP, mainly or exclusively as the 1-28-amino-acid alpha-hANP. Secretion is increased when there is hypervolemia of the central circulation, either acute or chronic, the stimulus being, it is presumed, atrial stretch. The clearance rate of alpha-hANP has been documented in healthy volunteers but not in patients with clinical ...

Atrial natriuretic factor in patients with acromegaly
European Journal of Clinical Pharmacology, 1990In acromegaly the plasma volume is chronically elevated and it returns to normal when the disease is successfully treated. To define the role of ANF in such a chronic disorder of extracellular fluid volume homeostasis the plasma level was assayed in 37 acromegalic patients with active or inactive (successfully treated) disease.

Atrial Natriuretic Factor and Liver Disease
Hepatology, 1993A working formulation for the role of ANF in the sodium retention of cirrhosis is summarized in Figure 4. Sodium retention is initiated early in cirrhosis, either as a result of hepatic venous outflow block or of primary vasodilation. The consequent intravascular volume expansion causes increases in ANF levels. At this stage of disease, the rise in ANF

Urinary cGMP as biological marker of the renal activity of atrial natriuretic factor.
American Journal of Physiology, 1988Current evidence suggests guanosine 3',5'-cyclic monophosphate (cGMP) serves as the second messenger for atrial natriuretic factor (ANF) in the kidney in vivo. We examined whether extracellular cGMP accumulation quantitatively reflected the concentration

Coexistence of guanylate cyclase and atrial natriuretic factor receptor in a 180-kD protein.
Science, 1987Atrial natriuretic factor (ANF) is a peptide hormone that is released from atria and regulates a number of physiological processes, including steroidogenesis in adrenal cortex and testes.
