Renal handling of aluminium.
Aluminium (Al) is absorbed from a variety of foodstuffs and medications. Its major route of elimination from the body is in the urine. However, current knowledge concerning its glomerular filtration and, more particularly, its reabsorption/secretion is fragmentary. Most (80-90%) of Al in the plasma is normally bound to protein (mainly transferrin) and is therefore unfilterable; the remainder is...
متن کاملRenal aluminium handling in the rat: a micropuncture assessment.
Uncertainties exist over the glomerular filtration of aluminium and virtually nothing is known about its segmental handling along the nephron. The present study has used micropuncture, combined with electrothermal atomic absorption spectroscopy, to determine directly the aluminium content of glomerular filtrate and of late PCTs (proximal convoluted tubules) and early distal tubules in anaesthet...
متن کاملThe Renal Handling of Hemoglobin
The fate of small doses of isotopically labeled isologous hemoglobin was studied in the rat. When haptoglobin depleted animals were given 2.0 mg of (59)Fe hemoglobin intravenously, nearly half was trapped by the kidneys. Kidney (59)Fe activity disappeared slowly over several weeks. Whatever iron was lost from the kidneys was largely reutilized. In contrast, the porphyrin of hemoglobin absorbed ...
متن کاملRenal Glucose Handling
OBJECTIVE Ipragliflozin, a sodium-glucose cotransporter 2 inhibitor, stimulates glycosuria and lowers glycemia in patients with type 2 diabetes (T2DM). The objective of this study was to assess the pharmacodynamics of ipragliflozin in T2DM patients with impaired renal function. RESEARCH DESIGN AND METHODS Glycosuria was measured before and after a single ipragliflozin dose in 8 nondiabetic su...
متن کاملThe renal handling of insulin.
The renal handling of insulin was studied by insulin immunoassay in arterial blood, renal venous blood, and urine of fasting patients with normal renal function and in peripheral venous blood and urine of normal subjects and patients with renal disease before and after an oral glucose load. A renal arteriovenous insulin concentration difference of approximately 29% was found and suggests that i...
