Oral administration of deltamethrin (5 mg/kg x7 or 15 or 21 days) was found to produce a time-dependent increase in the mRNA expression of xenobiotic metabolizing cytochrome P450 1A1 (CYP1A1), 1A2 and CYP2B1, 2B2 isoenzymes in rat brain.

RT-PCR analysis revealed dose-dependent increase in the mRNA expression of cerebral and hepatic CYP1A1, 1A2, 2B1, 2B2, and 2E1 isoenzymes in the offsprings exposed prenatally to deltamethrin.
