Figure 6. The renal MBF responses to PD 123319 (PD).

PD 123319 was given i.v., 50 μg kg⁻¹ min⁻¹ (PD; n = 8), or infused directly into the medullary interstitium, 5–10 μg min⁻¹, during background infusion of Ang II (30 ng kg⁻¹ min⁻¹i.v.) (Ang II + PD; n = 12). The RPP was maintained constant in both groups. Data are presented as means ± s.e.m. as a percentage of the pre-PD control value. *P < 0.05 versus pre-PD control.
