Oxidative stress can result from either the excessive production of reactive oxygen species (ROS) or an impaired antioxidant system, or both. It causes damage to lipids, proteins and DNA. Therefore, oxidative stress may be involved in carcinogenesis, and is associated with many types of cancer in dogs. The objective of this study was to compare the levels of malondialdehyde, protein hydroperoxides, glutathione, retinol and alpha-tocopherol between dogs with mast cell tumors and clinically healthy controls. Blood samples were obtained from eighteen clinically healthy dogs and fourteen dogs with spontaneous mast cell tumors. Malondialdehyde and protein hydroperoxides levels were measured by …

The α-tocopherol (TCP) state as well as enzymatic (superoxide dismutase [SOD] and catalase [CAT]) and nonenzymatic (reduced glutathione [GSH] and retinol) antioxidants in tissues of American minks (Neovison vison) given various levels of dietary vitamin E were examined. Three groups of farm-bred minks received different amounts of DL-α-tocopheryl acetate (10 mg/kg diet, control; 30 and 110 mg/kg diet, treatments denoted as E30 and E110, respectively) for 14 days in November. The TCP content was raised substantially in the kidneys and reduced in the livers of minks in the E110 group. The action of the 2 vitamin E doses on antioxidants …
