Investigation of the ion permeability of vessel walls

  • 14 Accesses

Abstract

A fundamentally new technique has been developed for determining the local ion permeability of the intact vessel wall in the presence of continuous blood flow. This technique has been used to investigate the permeability of the canine femoral artery with respect to Na and Cl ions using radioactive indicators. It is shown that for these two ions the permeability mechanism is different. The quantitative diffusion characteristics of C1 ions in the natural vessel wall are obtained.
