Hemodynamic parameters and renal blood flow following stimulation of renal tubular transport processes by treatment with thyroid hormones.
In adult rats, renal excretion of p-aminohippurate (PAH) can be stimulated by repeated administration of thyroid hormones. Data on renal cortical slices show clearly that a stimulation of active, carrier-mediated tubular transport processes is the most important cause. In vivo experiments also show an influence of treatment with thyroid hormones on various hemodynamic parameters. The diminution of vascular resistance in cortical and medullary regions of the kidney might contribute to the increased PAH excretion in thyroid hormone-treated rats.
