Collagen Orientation and Waviness within the Vein Wall

Popis výsledku v původním jazyce

Dominant directions and statistical distribution of collagen fibers undulation were investigated in histological sections from media and adventitia of human vena cava. Orientations of collagen fibers were analyzed by the in-house developed software Binary Directions. It was found that collagen fibers are aligned in circumferential direction in media. Contrary to that in adventitia fibers are arranged in longitudinal direction. In contrast to artery, no evidence of helically reinforced composite structure was found. Second goal was to find out which statistical distribution, usually using in structural models, fits to the undulation distribution of collagen fibers. Waviness was characterized by a probability density function for the strain necessary tostraighten a crimped fiber. The statistical analysis suggests that the waviness of collagen fibers is identical in media and adventitia. It was found that the average strain necessary for straightening collagen fibers is 0.24?0.11 (&
