Figure 6. Calf muscle blood flow and vascular conductance in response to phenylephrine and BHT-933.
Calf muscle blood flow (A and B) and vascular conductance (VC) (C and D) in response to phenylephrine (PE; left panels) and BHT-933 (right panels) during normothermia (NT) and leg heating (H). For either evaluation, there was no main effect of leg heating, yet there was a significant effect of the drug dose. Low and high doses for PE were 0.05 and 0.2 μg kg−1 min−1, respectively. Low and high doses for BHT-933 were 2.5 and 10.0 μg kg−1 min−1, respectively; †P < 0.05 vs. Baseline; ‡P < 0.05 vs. High Dose.
