Effects of chronic ethanol treatment on monoamine levels in rat hippocampus and...
Vasconcelos,S.M.M.; Cavalcante,R.A.; Aguiar,L.M.V.; Sousa,F.C.F.; Fonteles,M.M.F.; Viana,G.S.B.We studied the effects of ethanol on concentrations of noradrenaline (NE), dopamine (DA) and serotonin (5-HT) and their metabolites in rat hippocampus and striatum. Ethanol (2 or 4 g/kg, po, from a 20% aqueous solution) was administered daily to male Wistar rats (4-13 per group) for 30 days and animals were sacrificed 30 min or 48 h after the last administration. Monoamines were measured by HPLC and considered ...

Vasconcelos,S.M.M.; Macêdo,D.S.; Lima,L.O.; Sousa,F.C.F.; Fonteles,M.M.F.; Viana,G.S.B.We studied the effects of ethanol on the levels of norepinephrine, dopamine, serotonin (5-HT) and their metabolites as well as on D1- and D2-like receptors in the rat striatum. Ethanol (2 or 4 g/kg, po) was administered daily by gavage to male Wistar rats and on the 7th day, 30 min or 48 h after drug administration, the striatum was dissected for biochemical assays. Monoamine and metabolite concentrations were ...
