  • Title: [Effect of psychotropic substances on dopamine uptake by synaptosomes and glial cells].
    Author: Bakhanashvili TA, Blinkova NF, Maĭsov NI.
    Journal: Biull Eksp Biol Med; 1979 Mar; 87(3):237-9. PubMed ID: 427274.
    Abstract:
    Dophamine-H3 uptake by synaptosomes and glial cells of the cerebral cortex in rabbits and by the synaptosomes of the cerebral cortex in rats was studied. KM value of the dophamine-H3 uptake was found to be the same (0.075 +/- +/- 0.01 micrometer) in case of synaptosomes and glial cells. The rate of dophamine-H3 uptake by the rabbit cerebral cortex synaptosomes was twice that of the gial cells (as compared by protein). Among the psychotropic agents studied the most active symaptosome uptake inhibitors were phenamine and cocaine; they were less active in respect to glial uptake. Both types of uptake were inhibited by neuroleptics and antidepressants to the same degree. Results of this work conformed to the view on the participation of the strial dophaminergic link in the action mechanism of psychostimulants.
