Pron'ko PS, Kuz'mich AB, Abakumov GZ: [Effect of alcohol intoxication and aldehyde dehydrogenase inhibitors on lipid peroxidation in rat liver]. Ukr Biokhim Zh. 1999 Jul-Aug;71(4):79-83.
A single intraperitoneal administration of ethanol (3.5 g/kg) to rats induced a marked increase in lipid peroxidation and a decrease of antioxidative activity in the liver after 1 h when assessed by chemi-luminescence in liver homogenates. The pretreatment with aldehyde dehydrogenase inhibitor, disulfiram (200 mg/kg 24 hr before ethanol), caused a 10-fold elevation of the blood acetaldehyde levels, with no effect on the hepatic lipid peroxidation compared to control. Cyanamide (50 mg/kg, 2 h before the ethanol) increased approximately 100-fold the acetaldehyde levels, however, the changes in lipid peroxidation were not significantly different from that produced by ethanol alone. The present results suggest, that the metabolism of acetaldehyde and not acetaldehyde itself is responsible for the in vivo activation of lipid peroxidation during acute alcohol intoxication. Disulfiram prevents the ethanol-induced lipid peroxidation in the rat liver. |
