AGE FEATURES OF THE STRUCTURAL CHANGES IN ELASTIC MEMBRANES OF THE ABDOMINAL AORTA

Abstract

The morphometric analysis of elastic membranes of the human abdominal aorta was made; such parameters as average values of the number of membranes, the thickness and width of intervals between the adjacent membranes in differentage groups of males and females were studied. The histograms of the distribution of the thickness of the elastic membranes and the width of intervals between the adjacent membranes in different-age groups of males and females were analyzed. The main regularities and the nature of changes in the indicators of the number, the thickness of membranes and the width of intervals between the adjacent membranes in norm in patients at the age from 1 to 70 years were studied. The main stages of change in the structural characteristics of the elastic membranes were established. The time of completion of the processes of formation and growth of elastic membranes, the period of stabilization, and the period of aging of the elastic components of a vessel wall were determined. Differences in the duration of these periods for males and females were revealed. The morphometric methods allow one to establish structural changes in the elastic membranes of the human abdominal aorta with a higher accuracy, to reveal the time of appearance of these changes, to determine differences in the time of these periods for males and females.
