The purpose of the present study was to determine if elevated reactive oxygen ( ROS ) / nitrogen species ( RNS ) reported to be present in adriamycin ( ADR ) - induced cardiotoxicity actually resulted in cardiomyocyte oxidative / nitrative damage , and to quantitatively determine the time course and subcellular localization of these postulated damage products using an in vivo approach .
