hexachlorobenzene ( hcb ) produced increases in ethoxyresorufin ( err ) o-deethylase , aryl hydrocarbon hydroxylase ( ahh ) and aminopyrine n-demethylase activities in rat liver phenobarbital which were intermediate between those produced by phenobarbital and 3,4-benzpyrene ( bp ) , alpha-naphthoflavone ( anf ) selectivity inhibited err activity in bp and hcb-induced microsomes ( 94 % and 88 % ) .
