On the other hand, addition of antioxidants (diethyldithiocarbamate or N,N'-diphenyl-p-phenylenediamine), or cytochrome P-450 inhibitors (SKF-525A or metyrapone) to the incubation mixtures attenuated malondialdehyde production caused by dichlorvos and protected cells from death.

The number of these breaks was reduced by adding the cytochrome P450 inhibitor metyrapone.
Dichlorvos (DDVP)-induced DNA single strand breaks were investigated in isolated rat hepatocytes.

Hepatic microsomal cytochrome P-450 and aminopyrine demethylase activity were unchanged, but aniline hydroxylase activity was increased significantly by HPD and HFD.

Including the synergists piperonyl butoxide, a cytochrome P-450 monooxygenase inhibitor, or S,S,S-tributylphosphorotrithioate, an esterase inhibitor, in the methiocarb bioassays partially suppressed resistance in the most resistant populations.
Assays of acetylcholinesterase sensitivity to inhibition by methiocarb, dichlorvos, and eserine suggested insensitive acetylcholinesterase in two of the resistant populations.

These results suggest that cytochrome P450-dependent monooxygenase activities may be useful variables in toxicity tests with aquatic insects.
Parathion, dichlorvos, and aldicarb caused dose-related inhibition of cholinesterase (ChE) in 24-h bioassays with both species.
