title: Relevance of endothelial surface structure to the activity of vasoactive substances.
abstract: Increasingly it appears that expressions of vascular reactivity depend to a significant degree on reactions that occur on or near the endothelial surface. While the full scope of such reactions is not yet clear, some are now understood in terms of ultrastructural specializations of endothelium.
