Figure 6. The maximum rise in pulmonary arterial pressure (Ppa) (mean±SEM) from baseline in response to cumulative 0.95 ml of radiographic contrast media and normal saline in chronic hypoxic-induced pulmonary hypertensive rats. IOP, iopromide; IOT, iotrolan; IOX, ioxaglate; S, normal saline. All solutions caused a significant rise in Ppa from baseline (p<0.05). *, Saline vs IOT and IOX (p<0.05).
