Different patterns in the induction of metallothionein mRNA synthesis among isoforms after acute ethanol administration.

The induction of metallothionein (MT) isoform synthesis was investigated in mouse cerebral cortex 18 h after oral ethanol administration. The expression of MT-I isoform mRNA increased in a dose-dependent manner after ethanol loading at doses between 2 g/kg (ethanol/body weight) and 8 g/kg. Lipid peroxide formation, measured as the amount of malondialdehyde- reactive substances, remained at the control level after all of the administered ethanol doses.
