| Abstract: | It has been demonstrated that membrane-stabilizing agents, chlorpromazine and alpha-tocopherol, have no effect on the increased blood-brain barrier permeability for 14C-tyrosine, induced by a single injection of ethanol at a dose of 2 and 4 g/kg. Dopaminergic antagonist haloperidol prevented the increase of blood-brain barrier permeability induced by a single injection of 2 g/kg of ethanol and diminished the elevated barrier permeability caused by chronic 10-day alcoholization of animals, including abstinent ones. The role of membrane and neuromediator components in the mechanisms regulating blood-brain barrier functions is discussed. |
