[Atrial natriuretic peptide in patients with primary arterial hypertension]. / Przedsionkowy peptyd natriuretyczny u chorych z nadcisineniem tetniczym pierwotnym.

Atrial natriuretic peptide (ANP) activity was studied in 33 males with borderline and established essential hypertension. No significant differences of serum ANP concentration were stated in patients with borderline and established uncomplicated hypertension in comparison with the control group.

[Correlations of atrial natriuretic peptide and catecholamine levels in the blood during surgical removal of pheochromocytoma]. / Wspólzaleznosc miedzy stezeniem przedsionkowego peptydu natriuretycznego a katecholaminami we krwi w czasie operacyjnego usuniecia guza chromochlonnego.

Atrial natriuretic peptide concentrations (ANP) were determined in 4 patients with pheochromocytoma during its surgical removal. There was no correlation among ANP level, plasma catecholamines concentrations and blood pressure. Increase of plasma ANP concentration after tumor removal can be explained by simultaneously observed hypervolemia. It proves that ANP secretion mostly depends on enlarged central blood volume.

[Effects of 4-hour erect posture and furosemide on the blood level of atrial natriuretic peptide in patients with primary arterial hypertension]. / Wplyw 4-godzinnej czynnej pionizacji i furosemidu na stezenie przedsionkowego peptydu natriuretycznego we krwi u chorych z nadcisnieniem tetniczym pierwotnym.

The arterial pressure, the pulse frequency, the concentration of arterial natriuretic peptide (ANP), the aldosterone++ concentration and the plasma renin activity were determined in patients with primary hypertension after administration of furosemide in conditions of active assuming of erect position. The ANP concentration was lowered in that conditions both in the patients and in healthy subjects.
