title: Influence of glycosaminoglycan content of mass transfer behavior of porcine artery wall. Part 1. Diffusive transport of 45Ca2+ and 3HHO.
abstract: The diffusion coefficients of Ca2+ and H2O in in vitro porcine arterial tissue were determined to provide a measure of vascular permeability. The effect of anatomical location and diet on the magnitude of that permeability was evaluated. The diffusion coefficient of calcium was found to vary focally and, in addition, pulmonary artery was much more permeable than thoracic aorta. Four months feeding of a high lipid diet did not affect diffusive transport.
