| Abstract: | Perfusion of isolated kidneys from rats demonstrated the following nephrotoxic effects of Fluosol-DA: decreased glomerular filtration rate (GFR), urine flow rate (UFR), and fractional reabsorption of potassium (FrK+) (P less than 0.01). Fluosol-DA perfusions were at flow rates about equal to the physiologically normal rodent renal plasma flow rate of 4 ml/min. Stroma-free hemoglobin (SFH) perfusions, also at 4 ml/min, were associated with physiologically normal renal functions, as were those of control Krebs-Ringer bicarbonate (KRB) perfusions at 32 ml/min. |
