Abstract Ischemia reperfusion injury causes the release of free oxygen radicals. Free radicals initiate production toxic metabolites, such as malondialdehyde (MDA), through lipid peroxidation cellular membranes. Following peroxidation, antioxidant enzyme system is activated against reactive species (ROS) and attempts to protect cells from oxidative damage. There a balance between scavenging capacity enzymes ROS. Because this balance, total (TAC) measurement sensitive indicator overall...
