title: Interaction of dichloromethane and ethanol in rats: toxicokinetics and nerve conduction velocity.
abstract: The influence of a single combined administration of ethanol (174 mmol/kg per os) plus dichloromethane (1.6, 6.2, or 15.6 mmol/kg p.o.) on blood concentrations of the tested substances and of carboxyhemoglobin, and on nerve conduction velocity was studied in rats. The blood alcohol concentration was not influenced significantly by dichloromethane. The single high dose of ethanol completely inhibited the carboxyhemoglobin concentration increase due to dichloromethane, but did not prevent the dichloromethane-induced decrease of nerve conduction velocity. It produced initially lower, then higher concentrations of dichloromethane in blood than values seen after administration of dichloromethane per se. Rats treated with ethanol plus dichloromethane showed a more pronounced decrease of nerve conduction velocity compared with rats administered dichloromethane only.
