Abstrakt EN: The aim was to assess the morphology of micrographs of the elastin system in tunica media of aorta. We analyzed tissue samples of the anterior wall of non-atherosclerotic human adult abdominal aorta (n=19), normal human children’s abdominal aorta (n=6, age 1-2 years), porcine ascendent aorta (n=41) and descendent thoracic aorta (n=44). The shape of the power spectrum was assessed by the Feret’s ratio ofits polar coordinates histogram. The results revealed following average values of the Feret’s ratio (with standard deviation at confidence level of 90%): 94(1.1) in children’s aorta, 80.6(0.4) in human adult aorta, 90.5(0.2) in porcine ascendent aorta, and 91.1(0.2) in porcine descendent aorta. With increasing age, the abundance ratio of elastin and its complexity decreases, even in normal human aorta. We found no significant differences between samples of ascendent and descendent thoracic porcine aorta.
