Journal ArticleDOI
Repair in arterial tissue. Morphological and biochemical changes in rabbit aorta after a single dilatation injury.
TL;DR: Male albino rabbits subjected to a single mechanical dilatation of the descending thoracic aorta with a balloon catheter showed destruction and degeneration in the form of necrosis and calcification as well as regeneration and repair including new formation of cells, intercellular substance, and fibers.

Journal ArticleDOI
Injury and repair in arterial tissue in the rabbit. Analysis of DNA, RNA, hydroxyproline, and lactate dehydrogenase in experimental arteriosclerosis.
TL;DR: The aortic wall in rabbits was injured by pulling an inflated balloon catheter through the aorta and an increase of the RNA-DNA ratio in the aORTic wall 3 days after the injury was interpreted as a repair response of the arterial connective tissue to injury.
