HUMAN AORTIC MEDIA FIBROUS COMPONENT AGE ASSOCIATED FEATURES

A morphometric analysis of the men’s and women’s aged I year to 70years fibrous component of the abdominal part of human aortic media was carried out and such parameters as the specific area of the collagen fibers, the specific area of the elastin as a part of the membranes and of the elastin of the spaces between the membranes in the norm were studied. The qualitative changes of the collagen fibers characteristics, of the membranes elastin specific area and of the elastin of spaces between the membranes were analyzed in different age groups of men and women. An analysis of the quantitative changes of those indicators was carried out at men and women aged I year to 70 years. The main patterns and the nature of changes of the specific area of the collagen fibers, of the specific area of the elastin as a part of the membranes and the elastin of the spaces between the membranes in the norm at men and women of the same ages were revealed. The features of those indicators changing at men and women in different age groups was established and the ratio of the fibrous components in the aortic media in different age groups of men and women were determined. Statistically reliable differences between the contents of the collagen fibers, the specific area of the elastin as a part of the membranes and the elastin of the spaces between the membranes in the norm in different age groups were revealed. The most critical periods for changing of the fibrous component of the abdominal part of the human aortic media were determined.
