Figure 1 Illustrated protocol.*Inulin concentration in urine measured at these points, blood concentration measured at mid point in the time period. **Inulin infusion started one hour prior to the start of the experiment. Postcontrast (PC) values for a given period were summated and the means provided in the Results section.

Figure 2 Percent change in renal blood flow (B) and glomerular filtration rate (A) from baseline.*P < 0.05 compared with control. Kidney International 1999 56, 206-210DOI: (10.1046/j.1523-1755.1999.00528.x) Copyright © 1999 International Society of Nephrology Terms and Conditions

Figure 3 Duration of vasoconstriction. The duration of vasoconstriction is defined as the time that renal blood flow fell below the baseline value until it returns to baseline (#P < 0.01 vs. fenoldopam; *P < 0.01 vs. control or recovery).
