We analyzed the spatial structure of contact radiographs of barium-filled pulmonary arteries
of rats raised in room air and in two environments that induce pulmonary arterial
hypertension (PAH)-hypoxia and hyperoxia. We found that the spatial structure of the
pulmonary arteries was fractal in both the control and the hypertensive lungs. The fractal
dimension of the pulmonary arteries of the control lungs was 1.62+/-0.01 (mean+/-SEM),
which is greater than that of both the hypoxic lungs 1.50+/-0.03 (p< 0.01) and the hyperoxic …
