Diisopropylphosphorofluoridate (DFP) increased the specific activity of choline acetyltransferase (ChAT) in mouse spinal cord cell cultures but paraoxon did not, though both toxicants inhibited cholinesterase activity to a comparable extent. This effect of DFP was observed after prolonged exposure but not after short-term application to the cultures. It is postulated that this delayed effect of DFP in vitro may possibly be related tothe delayed neuropathy caused by DFP in certain species in vivo.
