Brain membrane disordering after acute in vivo administration of ethanol, isopropanol or t-butanol in rats.


Brain synaptosomal membranes were prepared from rats sacrificed 18 hr after a single intragastric dose of water or of ethanol (100 mmol/kg), when blood ethanol had fallen almost to zero. Fluorescence polarization of DPH, and (Na+ + K+)ATPase activity, were studied in these membranes in the presence of 0, 0.175, 0.3 or 0.7 M ethanol in vitro. After in vivo… (More)
