Activities of hepatic enzymes related to ethanol oxidation and effects of ethanol on hepatic metabolites in rats with chronic liver injury. 1979

H Kono, and M Fujii, and T Sokabe, and J Kaneshige

To study the effects of ethanol on liver chronically injured by CCl4, activities of hepatic enzymes related to ethanol oxidation, influences of ethanol on hepatic metabolites, and blood ethanol disappearance were observed. (1) Activities of alcohol dehydrogenase, low- and high-Km aldehyde dehydrogenase, microsomal ethanol-oxidizing system and drug-metabolizing enzyme were remarkably decreased in the injured liver. (2) Increases in lactate/pyruvate and beta-hydroxybutyrate/acetacetate ratios were shown in control liver 2 h after ethanol ingestion. Similar but less pronounced effects of ethanol on the 'redox state' were also seen in rats with chronic liver injury. (3) Delay in ethanol disappearance was not observed until 12 h after ethanol ingestion. The ethanol-induced changes in the redox state in the injured liver were similar to those in controls. Higher ethanol concentrations in blood from rats with chronic liver injury could be related to potentiate the injured liver.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D010084	Oxidation-Reduction	A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471).	Redox,Oxidation Reduction
D002252	Carbon Tetrachloride Poisoning	Poisoning that results from ingestion, injection, inhalation, or skin absorption of CARBON TETRACHLORIDE.	CCl4 Poisoning,Poisoning, CCl4,Poisoning, Carbon Tetrachloride,CCl4 Poisonings,Carbon Tetrachloride Poisonings,Poisonings, Carbon Tetrachloride
D000431	Ethanol	A clear, colorless liquid rapidly absorbed from the gastrointestinal tract and distributed throughout the body. It has bactericidal activity and is used often as a topical disinfectant. It is widely used as a solvent and preservative in pharmaceutical preparations as well as serving as the primary ingredient in ALCOHOLIC BEVERAGES.

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.
