EXTON, PA -- (MARKET WIRE) -- April 30, 2007 -- Rheologics Technologies, Inc. ("Rheologics" or the "Company") (PINKSHEETS: RTGI), the leader in the study of blood viscosity and its relationship to cardiovascular disease, announces today the publication of "The Origin of Atherosclerosis: What Really Initiates the Inflammatory Process," a book by Rheologics Chairman Kenneth R. Kensey, MD, and Young I. Cho, PhD.
