An analysis of the optimal conditions for perfusing an isolated rabbit kidney with homologous blood.
Isolated rabbit kidneys were perfused in a closed-circuit system with a number of media such a Krebs-Henseleit bicarbonate buffer with albumin, homologous platelet-free plasma, serum and whole blood. All of these media were unsatisfactory. In contrast, fresh blood deprived of platelets, leukocytes, floating lipoproteins, microaggregates and microclots did not cause vasoconstriction of the isolated kidney. Renal blood flow, glomerular filtration rate, urinary flow and glucose, cations and renal water reabsorption were approximately normal.
