[Water and ionic variations in dog kidneys during hypothermic plasma perfusion(author's transl)].
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.
