Figure 6.

Influence of iloprost infusion and its combination with AH 6809 and BIM on the area under the curve of the U46619-elicited pulmonary hypertension. Area under the curve (AUC) is given (mean ± SEM of 4 independent experiments each). The AUC was calculated by standard techniques and is given as mmHg × min. **: p < 0.01; ***: p < 0.001 as compared to AUC of sole iloprost infusion.
