Abstract

We measured in-vivo poroelastic material constants and hydraulic conductance in intact segments of carotid arteries in normal and spontaneously hypertensive rats (SHRs). The rat carotid arterial wall was treated as a 'porohyperelastic' material. Strain and stress components were calculated based on Fung's pseudo-strain exponential energy function W. The material constants in the SHRs (N=9) were higher (P < 0.05) than in normal rats (N=10). The hydraulic conductivity of the arterial wall, calculated from the filtration data, was lower (P <0.05) at both 50 and 100 mmHg in the SHRs (N=6) when compared to normal rats (N=7).
