Oxidative stress, antioxidants, and assessment of oxidative stress in dogs and cats

xidative stress is defined as ROS in excess of anti-oxidant defense mechanisms. Oxidative stress can result from an excess of ROS, a reduction in antioxi-dants, or both. Damage attributable to oxidative stress is widespread, and oxidative stress is recognized as a prominent feature in numerous disease processes, in-cluding neoplasia and heart disease, as well as trauma and burns.
