[Clearance behavior of the kidney in relation to ANF in the autologous dog transplantation model].

ANF is totally filtrated by the kidney and is degradated in the brush border of the tubuli. In an experimental transplant model in dogs excretion of ANF is investigated after a cold ischemia period of 48 h and HTK-protection. The ANF-renin-antagonism was of interest respectively. The experiments demonstrated that the filtration in the glomeruli and the function of the endopeptidases in the brush border is normal after a cold ischemia period of 48 and HTK-protection. There is a linear correlation between the concentration of ANF in the renal vein and the aorta. An antagonism of ANF and renin could not be found. ANF is discussed as an additional ischemia parameter in renal transplantation.
