Abstract

Reactive oxygen species (ROS) are believed to be responsible for pathogenesis of various diseases affecting tissues and systems. ROS generated by mitochondrial electron transport chain as well as extra-mitochondrially are eliminated by the respective defense mechanisms. We checked the activity of ROS generating system such as xanthine oxidase and also the parameter of ROS defense mechanism e.g. superoxide dismutase(SOD), catalase, glutathione peroxidase (GPox), reduced glutathione content (GSH) and glucose-6-phosphate dehydrogenase (G6PDH) in mitochondrial and post-mitochondrial fractions from various tissues (liver, kidney, brain and heart) of normal rats. Extent of lipid peroxidation (LPO) which is immediate consequence of ROS generation was also examined. Our results shows that significant tissue-specific differences exist in mitochondrial and cytosolic ROS generating systems and ROS defense mechanisms.
