Butylated Hydroxyanisole: Mixture of 2- and 3-tert-butyl-4-methoxyphenols that is used as an antioxidant in foods, cosmetics, and pharmaceuticals.Butylated Hydroxytoluene: A di-tert-butyl PHENOL with antioxidant properties.Anisoles: A group of compounds that are derivatives of methoxybenzene and contain the general formula R-C7H7O.Ethoxyquin: Antioxidant; also a post-harvest dip to prevent scald on apples and pears.Propyl Gallate: Antioxidant for foods, fats, oils, ethers, emulsions, waxes, and transformer oils.Antioxidants: Naturally occurring or synthetic substances that inhibit or retard the oxidation of a substance to which it is added. They counteract the harmful and damaging effects of oxidation in animal tissues.N-Nitrosopyrrolidine: Carcinogenic nitrosamine that may be formed from preservatives in meats during their preparation or in the liver during metabolism.Glutathione Transferase: A transferase that catalyzes the addition of aliphatic, aromatic, or heterocyclic FREE RADICALS as well as EPOXIDES and arene oxides to GLUTATHIONE. Addition takes place at the SULFUR. It also catalyzes the reduction of polyol nitrate by glutathione to polyol and nitrite.HydroquinonesPicratesBenzopyrenes: A class of chemicals that contain an anthracene ring with a naphthalene ring attached to it.Rats, Inbred F344Enzyme Induction: An increase in the rate of synthesis of an enzyme due to the presence of an inducer which acts to derepress the gene responsible for enzyme synthesis.Free Radical Scavengers: Substances that influence the course of a chemical reaction by ready combination with free radicals. Among other effects, this combining activity protects pancreatic islets against damage by cytokines and prevents myocardial and pulmonary perfusion injuries.Carcinogens: Substances that increase the risk of NEOPLASMS in humans or animals. Both genotoxic chemicals, which affect DNA directly, and nongenotoxic chemicals, which induce neoplasms by other mechanism, are included.Stomach: An organ of digestion situated in the left upper quadrant of the abdomen between the termination of the ESOPHAGUS and the beginning of the DUODENUM.Thiocarbamates: Carbamates in which the -CO- group has been replaced by a -CS- group.Phenols: Benzene derivatives that include one or more hydroxyl groups attached to the ring structure.Liver: A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.Ascorbic Acid: A six carbon compound related to glucose. It is found naturally in citrus fruits and many vegetables. Ascorbic acid is an essential nutrient in human diets, and necessary to maintain connective tissue and bone. Its biologically active form, vitamin C, functions as a reducing agent and coenzyme in several metabolic pathways. Vitamin C is considered an antioxidant.
