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.

Studies on the natriuresis of fasting
Metabolism, 1966Abstract By employing low sodium diets in the prefast period, the effects of salt restriction and fasting were temporarily separated so that the character and magnitude of the natriuresis due to caloric withdrawal could be determined. During fasting, there was a rise in the mean sodium excretion beginning on the second day, reaching a peak on the ...

Natriuresis induced by mild hypernatremia in humans
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2002The hypothesis that increases in plasma sodium induce natriuresis independently of changes in body fluid volume was tested in six slightly dehydrated seated subjects on controlled sodium intake (150 mmol/day). NaCl (3.85 mmol/kg) was infused intravenously over 90 min as isotonic (Iso) or as hypertonic saline (Hyper, 855 mmol/l).

Pressure diuresis and natriuresis in cirrhotic rats
American Journal of Physiology-Gastrointestinal and Liver Physiology, 1993Arterial hypotension in liver cirrhosis has been proposed as a major mechanism contributing to renal sodium and water retention. To evaluate kidney excretory responses at different levels of arterial pressure (AP), we have characterized the relationships between renal perfusion pressure (RPP) and sodium and water excretion in carbon tetrachloride ...

Natriuresis and vascular tone in toxemia of pregnancy
American Journal of Obstetrics and Gynecology, 1960E v E N though the signs and symptoms of pre-eclampsia and eclampsia are well known, the etiology and exact pathophysiology remain obscure. Through meticulous prenatal and puerperal care by controlling the early manifestations of the disease, much has been accomplished in preventing the severe degrees of pre-eclampsia and eclampsia.

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).

Exaggerated Natriuresis in ACTH Hypertension in Sheep
Nephron, 1978Adrenocorticotrophic hormone (ACTH) administration to sheep (100 IU/day) produces a sustained increase in arterial pressure within 24 h. The effect of ACTH on excretion of an intravenous saline load was tested in 8 adult cross-bred Merino ewes. A significant diuretic response to saline loading was found after 24 h but no increased natriuresis.

Nonpressor mechanisms in CNS-induced natriuresis
American Journal of Physiology-Renal Physiology, 1979Ventriculocisternal perfusion was performed in pentobarbital-anesthetized dogs. Perfusion of high Na (300 mM NaCl) artificial cerebrospinal fluid (CSF) (E) for 2 h was preceded by 2 h of control (C) and was followed by 2 h of recovery (R) during which normal (150 mM NaCl) artificial CSF was perfused.
