Influence of CP94 on microsomal total cytochrome P450 content (A) and BROD activity (B) in C57BL/10ScSn and SWR mice after 2 weeks' exposure. Results are mean ± SD of 5 mice per group. BROD activity is the oxidation of benzyloxyresorufin to resorufin catalyzed in particular by CYP2B isoforms of cytochrome P450.
