title: Interaction of CDP-choline with synaptosomal transport of biogenic amines and their precursors in vitro and in vivo in the rat corpus striatum.
abstract: Added to a striatal synaptosomal homogenate of rat brain, CDP-choline 10(-4) M inhibits the uptake of norepinephrine (NE), dopamine (DA) and serotonin (5 HT) in a competitive fashion and enhances the uptake of tyrosine and tryptophan; administered to animals, CDP-choline (50 mg/kg/l h/i.v.) inhibits only the in vitro uptake of DA but enhances the uptake of precursors.
