Acute Effects of Vardenafil on Pulmonary Artery Responsiveness in Pulmonary Hypertension

Figure 3

Effects of L-NAME (10⁻⁴ M; 𝑛=15) and ODQ (10⁻⁵ M; 𝑛=15) on the relaxations induced by vardenafil in control (a) and pulmonary hypertension group (b). Data were calculated relative to the maximal changes from the contraction produced by phenylephrine (10⁻⁶ M) in each ring, which was taken as 100%. *𝑃<0.05 as compared with control.
