摘要: Many toxic effects of cocaine are attributed to reactive oxygen species (ROS) generated during its metabolism. Recently, it has been suggested that the biological action ROS is often confused with endogenously sulfur (RSS). The aim this study was evaluate impact on thiols and RSS in rat liver kidney drug self-administration (SA) paradigm yoked delivery model (YC) followed by abstinence extinction training. level as well formed anaerobic metabolism cysteine sulfate were assayed. In addition, activity enzymes involved formation glutathione determined. liver, following direct administration (SA YC), levels decreased, while kidneys, increased contents both groups. These changes maintained these tissues abstinence. sulfates changed only liver. kidney, shifted towards an pathway. Our demonstrates for first time thiol rats after
