Aortic connective tissue in ageing--a biochemical study.
The biochemical analysis of samples of aortic connective tissue was carried out in 22 subjects from 9 to 84 years old. Aortic samples were taken at necropsy performed after sudden or, more often, traumatic death. The results suggest that aging of the aorta is accompanied by an increase both in collagen content and in total sugar content when expressed as mg/cm2 while the elastin content, when expressed in the same way, does not undergo any variation.
