Renal disposition of colistin in the isolated perfused rat kidney.
Nephrotoxicity is an important limitation to the clinical use of colistin against Pseudomonas aeruginosa and other gram-negative pathogens. Previous work reported net tubular reabsorption of colistin by the kidney in vivo, but there is no knowledge of its disposition within the kidney. This study investigated the renal disposition and potential transport mechanisms of colistin in the isolated p...
متن کاملRenal excretion and accumulation kinetics of 2-methylbenzoylglycine in the isolated perfused rat kidney.
The effect of protein binding on kidney function has been studied by investigating the renal accumulation and secretion of the hippurate analogue 2-methylbenzoylglycine in the isolated perfused rat kidney in the absence and presence of bovine serum albumin (BSA). Experiments were performed with either 2.5% pluronic or a combination of 2.2% pluronic and 2% BSA as oncotic agents; a wide concentra...
متن کاملThe Isolated Perfused Rat Kidney
1. In the isolated rat kidney, perfused at constant pressure with a medium free from renin substrate, addition of angiotensin I to the perfusate decreases renal 'plasma' flow. 2. A peptide inhibitor, SQ 20881, of converting enzyme reduces the vasoconstrictor effect of angiotensin I up to a maximum of 87%, the degree of inhibition being dose-dependent. 3. The molar ratio of equi-effective doses ...
متن کاملGluconeogenesis in the isolated perfused rat kidney.
The perfused rat kidney was used for a study of gluconeogenesis. The kidney was completely isolated and perfused with Krebs-Henseleit bicarbonate buffer containing 5% albumin. Perfusion flow rate and pressure remained stable for 2 to 3 hours, although the glomerular filtration rate diminished with time. The fractional reabsorption of both water and sodium was 0.92 during the 1st hour of perfusi...
متن کاملPotassium transport by the isolated perfused kidney.
Rat kidneys perfused outside of the body with an artificial medium are able to increase their fractional excretion of potassium in response to a rising concentration of potassium in the medium but never show net secretion of potassium. By contrast, isolated perfused kidneys from chronically potassium-loaded rats regularly secrete potassium in excess of the amount filtered. Ouabain completely bl...
