title: [Comparative study of the changes in structural parameters of collagen fibers during natural aging and pneumosclerosis formation].
abstract: Changes in diameter of the collagen fibers and their number in fascicles of the rat lung in the process of natural ageing and formation of radiation-induced pneumo-sclerosis were studied electron microscopically. The decrease of the fibril thickness and the increase of their number in fascicles progressed during the postirradiation period and reached the values absent in the control animals.
