Mechanisms regulating the renal excretion of sodium during pregnancy.
Observations were made on the relation of the renin-angiotensin-aldosterone system and renal hemodynamic function to sodium balance in 43 pregnant dogs. Daily balance studies revealed that about 30-40% of ingested sodium was retained during the last half of pregnancy; during the same period, potassium balance was also positive but to a lesser extent. For groups of pregnant dogs, plasma renin ac...
متن کاملRenal excretion of sodium in arterial hypertension.
Patients with arterial hypertension excrete a sodium load more rapidly than do individuals with normal blood pressure. The relationship of this abnormal sodium excretory response to blood pressure and such extrarenal factors as the central nervous system, dietary salt intake, body fluid volume and sodium content, and the adrenal glands has been studied. On the basis of this and other evidence, ...
متن کاملRenal sodium handling and sodium sensitivity
The pathophysiology of hypertension, which affects over 1 billion individuals worldwide, involves the integration of the actions of multiple organ systems, including the kidney. The kidney, which governs sodium excretion via several mechanisms including pressure natriuresis and the actions of renal sodium transporters, is central to long term blood pressure regulation and the salt sensitivity o...
متن کاملSodium, kidney and renal sodium retention
The tight regulation of the body's sodium and chloride concentrations is so important that multiple mechanisms work in concert to control them, and a minimal amount of salt is required for survival. Sodium (Na) and chloride (Cl) are the principal ions in the extracellular fluid, especially in blood plasma. Sodium retention is the most common renal abnormality of cirrhosis and eventually leads t...
متن کاملHormonal regulation of renal sodium and water excretion during normotensive sodium loading in conscious dogs.
Saline was infused intravenously for 90 min to normal, sodium-replete conscious dogs at three different rates (6, 20, and 30 micromol x kg(-1) x min(-1)) as hypertonic solutions (HyperLoad-6, HyperLoad-20, and HyperLoad-30, respectively) or as isotonic solutions (IsoLoad-6, IsoLoad-20, and IsoLoad-30, respectively). Mean arterial blood pressure did not change with any infusion of 6 or 20 microm...
