We investigated the effect of changes in micro-structural components on the macroscopic level of mechanical behavior in porcine thoracic aorta. We carried out uniaxial stretching test and histological observation for vascular segments which were subjected to freezing and thawing. We chose five conditions of freezing and thawing, applying each condition to two aortas. From each aorta we took 3 specimens for the mechanical test and 1 for histological observation. The results show the tissue stiffening by freezing and thawing and no correlation between the stiffening and micro-structural changes. These findings may suggest the stiffening of fibrous components such as elastin and collagen.
