Title Effects of chronic ethanol consumption on hepatic metabolism of aromatic and chlorinated hydrocarbons in rats.
Bibliographic information Nov. 1980, Vol.37, No.4, p.382-386. 23 ref.
Abstract The activities of liver drug-metabolising enzymes for 16 aromatic or chlorinated hydrocarbons were measured in rats after daily intake of ethanol (30% of total energy intake) for 3 weeks. Ethanol only slightly increased the microsomal cytochrome P-450 content, but increased in vitro metabolism of most hydrocarbons 3-6 fold. A major part of this enhanced activity disappeared after withdrawal of ethanol, suggesting that recent intake of ethanol plays an important part in accelerating the metabolism of hydrocarbons. The enzyme activity enhanced by ethanol was related to changes occurring not in the soluble but in the microsomal fractions. A metabolism study with toluene showed its in vivo metabolism to be increased by chronic ethanol consumption in rats.
