[Kidney function during total blood substitution in the rat (author's transl)]. / Nierenfunktion während des totalen Blutersatzes bei der Ratte

Urine production, glomerular filtration rate (GFR) and Na+ transport of the kidney were studied in rats after complete substitution of the blood with a fluorocarbon emulsion. The urine production is found to be increased, the GFR lowered. The Na+ load as a function of the GFR is reduced while the relative Na+ reabsorption with values in the range of 98-99% of the load is normal.

[Water and ionic variations in dog kidneys during hypothermic plasma perfusion(author's transl)]. / Electrolyt- und Wasserverschiebungen an hypotherm mit Plasma perfundierten Hundenieren

Dog kidneys have been perfused with homologous plasma at plus 6 degrees-C for 24 and 48 h and the water, K+ and Na+ variations in the cortex and medulla have been studied. After 24 h perfusion Na+-gain and K+-loss in the cortex are found while water content shows no changes. After 48 h perfusion additional increase of Na+ and gain of water are observed while the K+ content remains unchanged as compared with the cortex after 24 h perfusion time. In the medulla after 24 h perfusion K+ loss and water gain are registered while the Na+ content remains unchanged. In the following 24 h no additional changes of the K+, Na+ or water contents are observed.
