Lipid peroxidation and retinal degeneration. 1984

R E Anderson, and L M Rapp, and R D Wiegand

Retinal degenerations were produced in albino rats by exposure to constant illumination or in frogs and albino rats by intravitreal injections of ferrous sulfate. Both treatments resulted in the loss of long-chain polyunsaturated fatty acids and the accumulation of lipid hydroperoxides in isolated rod outer segments. We suggest that lipid peroxidation is a factor in certain types of retinal degenerations.

UI MeSH Term Description Entries
D008027 Light That portion of the electromagnetic spectrum in the visible, ultraviolet, and infrared range. Light, Visible,Photoradiation,Radiation, Visible,Visible Radiation,Photoradiations,Radiations, Visible,Visible Light,Visible Radiations
D008054 Lipid Peroxides Peroxides produced in the presence of a free radical by the oxidation of unsaturated fatty acids in the cell in the presence of molecular oxygen. The formation of lipid peroxides results in the destruction of the original lipid leading to the loss of integrity of the membranes. They therefore cause a variety of toxic effects in vivo and their formation is considered a pathological process in biological systems. Their formation can be inhibited by antioxidants, such as vitamin E, structural separation or low oxygen tension.

D011894 Rana pipiens A highly variable species of the family Ranidae in Canada, the United States and Central America. It is the most widely used Anuran in biomedical research. Frog, Leopard,Leopard Frog,Lithobates pipiens,Frogs, Leopard,Leopard Frogs
D012162 Retinal Degeneration A retrogressive pathological change in the retina, focal or generalized, caused by genetic defects, inflammation, trauma, vascular disease, or aging. Degeneration affecting predominantly the macula lutea of the retina is MACULAR DEGENERATION.

D005260 Female Females
D005296 Ferrous Compounds Inorganic or organic compounds that contain divalent iron. Compounds, Ferrous
D005609 Free Radicals Highly reactive molecules with an unsatisfied electron valence pair. Free radicals are produced in both normal and pathological processes. Free radicals include reactive oxygen and nitrogen species (RONS). They are proven or suspected agents of tissue damage in a wide variety of circumstances including radiation, damage from environment chemicals, and aging. Natural and pharmacological prevention of free radical damage is being actively investigated. Free Radical
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
