Abstract
Summary
Changes comparable to those of physiological aging were induced by x-radiation in the tunica media of elastic arteries of mice of different ages. In the elastic arteries of 20 to 30 days and 80 to 100 days old irradiated mice there were increased amounts of ground substance, increased numbers of interlamellar fibers, and premature raggedness and fraying of the elastic membranes. No changes attributable to irradiation were seen in the arteries of the old mice.
