  • Title: Synaptosomal uptake and release of dopamine and 5-hydroxy-tryptamine in the nucleus accumbens in vitro following in vivo administration of lysergic acid diethylamide in rats.
    Author: Hetey L, Quiring K.
    Journal: Acta Biol Med Ger; 1980; 39(8-9):889-95. PubMed ID: 7282218.
    Abstract:
    The uptake and the depolarisation-induced release of dopamine (DA) and serotonin (5-HT) were investigated after systemic application of LSD on synaptosomes of the nucleus accumbens of rats. For the release experiments synaptosomes were prelabelled with [14C]-DA and [3H]-5-HT, respectively, and superfused with physiological and potassium-enriched (50 mM) solutions. Low doses of LSD (0.1 and 0.5 mg/kg i. p.) induced a dose-dependent inhibition of the DA-release and an increase of the DA-uptake, respectively. LSD inhibited both the release and the uptake of 5-HT significantly. The results are discussed with respect to a reliable characterization of the in vivo induced effects of LSD on the isolated synaptosomes.
