Transient Morphological and Biochemical Alterations of Arterial Proteoglycan during Early Wound Healing

Proteoglycan alterations in the carotid arteries of normolipemic rabbits during the first 14 days after injury were evaluated by morphometric analysis of ruthenium red-stained sections using transmission electron microscopy and by incorporation of 35S-sulfate. Two types of de-endothelializing injury were compared, air-drying and balloon catheter. Three days after either injury, a transient increase in concentration of 35S-labeled …
