acute exposure to ethanol produced a concentration-dependent decrease in depolarization-evoked 45ca2+ uptake , while prolonged ( 2-10 days ) exposure led to a reciprocal increase in 45ca2+ uptake and in the number of ca-channel binding sites labeled by the dihydropyridine ca-channel antagonist [ 3h ] nitrendipine .
