Our preceding studies have reported that 2,2',5,5'-tetrachlorobiphenyl (tetraCB)(CB52) is mainly metabolized to 3-hydroxy (OH)-metabolite by phenobarbital (PB)-inducible cytochrome P450 (P450) isoforms such as CYP2B1 and CYP2B18. In this study, the metabolism of CB52 by liver microsomes of untreated and PB-treated
