Figure 1From: Lung vasodilatory response to inhaled iloprost in experimental pulmonary hypertension: amplification by different type phosphodiesterase inhibitorsDose effect curves of different PDE inhibitors on U46619-elicited pulmonary hypertension (a) and systemic arterial pressure (b). (a) Pulmonary artery pressure drop (ΔPPA, in mmHg) and systemic arterial pressure drop (ΔPSA, in mmHg) (b) are given (mean ± SEM of 6 independent experiments each). PDE-inhibitors were applied in different doses as short-term infusion.Back to article page
