Abstract

Membrane binding of ethanol, anesthetics, and hydrophobic molecules in brain synaptosomes and liver mitochondria from rats is conspicuously reduced after long-term consumption of ethanol. The membranes are resistant to structural disordering by both ethanol and halothane. Tolerance, cross-tolerance, and dependence in chronic alcoholics may in part result from membrane alterations that inhibit the binding of ethanol and other drugs.
