Volume natriuresis vs. pressure natriuresis
Acta Physiologica Scandinavica, 2004AbstractBody fluid regulation depends on regulation of renal excretion. This includes a fast vasopressin‐mediated water‐retaining mechanism, and slower, complex sodium‐retaining systems dominated by the renin–angiotensin aldosterone cascade. The sensory mechanisms of sodium control are not identified; effectors may include renal arterial pressure ...

NOCTURNAL NATRIURESIS IN HYPERTHYROIDISM
Clinical Endocrinology, 1982SUMMARYWe measured urine flow and the renal excretion of total solute, sodium, potassium and calcium in eleven patients with hyperthyroidism before and after treatment. Mean nocturnal sodium excretion was significantly greater (P < 0·05) during hyperthyroidism and was unaccompanied by any significant alterations in day time or 24‐h values.

Mechanisms of pressure natriuresis
Current Hypertension Reports, 2002A central component of the feedback system for long-term control of arterial pressure is the pressure-natriuresis mechanism, whereby increases in renal perfusion pressure lead to decreases in sodium reabsorption and increases in sodium excretion. The specific intrarenal mechanism for the decrease in tubular reabsorption in response to increases in ...

Reduced natriuresis during weightlessness
The Clinical Investigator, 1993The kidney response to weightlessness was measured in one volunteer during a 1-week space mission. Shortly after entering microgravity and later during the mission, consecutive urine sampling periods were monitored, covering in total about 50% of the inflight time.

PRESSURE NATRIURESIS IN HYPERTENSION.
Acta Medica Scandinavica, 1981ABSTRACTPressure natriuresis, defined as the relationship between sodium excretion and mean arterial pressure (MAP), was assessed during graded reduction of arterial pressure with nitroprusside in 16 essential hypertensives (EH). In all patients, sodium excretion fell linearly with reductions in arterial pressure (r > 0.68; p < 0.05).

Exaggerated natriuresis in essential hypertension
The American Journal of Medicine, 1958P ATIENTS with essential hypertension excrete more sodium than do normotensive patients in response to the infusion of hypertonic saline solution [7-d]. The work reported in this paper attempts to assay the role of the renal tubule in the genesis of this exaggerated natriuresis.

Mechanism of Taurine Natriuresis in Rats
1989Taurine, a sulfur containing amino acid, is abundant in many organs and tissues in mammals1. However, its physiological significance has been hardly understood. We reported that daily urinary taurine excretion significantly decreased in patients with essential hypertension, and administration of taurine increased urinary kallikrein and decreased blood ...

Management of Neurosurgical Patients with Hyponatremia and Natriuresis
Neurosurgery, 1994The main objective of our study was to evolve a practical management protocol for neurosurgical patients with hyponatremia and natriuresis, based on their blood volume status and hematocrit. Twenty-one patients with hyponatremia and natriuresis and 3 control patients were studied.

Hypertension, Natriuresis, and the Renal Prostaglandins
Annals of Internal Medicine, 1969Excerpt Prostaglandins are a group of cyclical fatty acids with diverse potent biological activities which were discovered independently in the early 1930's by Goldblatt (1) and von Euler (2).
