Carbon tetrachloride (CCl4)-induced hepatotoxicity was potentiated by pretreatment with beta-phenethyl alcohol, abundantly present in sake. The injury was determined by serum GPT levels and histological examination. Similar results were observed in ethanol- and phenobarbital-pretreated rats. Acetaminophen-induced hepatotoxicity was not accentuated by beta-phenethyl alcohol or ethanol pretreatment. The activities of liver microsomal enzymes, such as cytochrome P-450, cytochrome b5 reductase, aniline hydroxylase and aminopyrine demethylase, were not altered in beta-phenethyl alcohol-pretreated rats. Thus, CCl4-induced hepatotoxicity potentiation by beta-phenethyl alcohol administration is postulated to be due to a mechanism other than increased free radical generation.
