[Intracellular peroxidation processes in chronic alcohol intoxication]. 1989

S V Pirozhkov, and L F Panchenko

The data available in literature concerning the induction of lipid peroxidation (LP) with chronic alcohol administration are systematized. LP can be considered as one of the main processes leading to cellular membrane damage. The cytotoxic activity is attributed not only to the free radicals but also to the final products of the lipid hydroperoxide decomposition, such as malonic dialdehyde and 4-hydroxyalkenals. Data about antioxidative defence enzymes (glutathione peroxidase and transferase, catalase superoxide dismutase) and less investigated protein factors which inhibit LP are summarized; particular attention is paid to changes in their activity during chronic alcoholization. Molecular mechanisms underlying the LP stimulation in the liver tissue against a background of ethanol ingestion are analyzed. New data are presented on the role of peroxisomes in the development of alcohol cardiomyopathy.

UI MeSH Term Description Entries
D008099 Liver A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances. Livers
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

D000437 Alcoholism A primary, chronic disease with genetic, psychosocial, and environmental factors influencing its development and manifestations. The disease is often progressive and fatal. It is characterized by impaired control over drinking, preoccupation with the drug alcohol, use of alcohol despite adverse consequences, and distortions in thinking, most notably denial. Each of these symptoms may be continuous or periodic.
