title: [Inhibition of serotonin uptake in synaptosomes and glia cells by some pharmacological substances].
abstract: The uptake of serotonin -14 C by glial cells and synaptosomes of the rabbit brain cortex was studied. The Km value of the uptake of serotonin -14 C proved to be equal (0.83 + 0.02 microM) both for synaptosomes and glial cells. Synaptosomes of the rabbit brain cortex take up serotonin -14 C twice as fast as glial cells (uptake rates were compared from protein). Among psychotropic drugs studied the tricyclic antidepressant imipramine and psychostimulant cocaine turned out the most active inhibitors of both synaptosomal and glial uptake of serotonin -14 C. The drugs in 50 microM concentration inhibit the uptake of serotonin -14 C in synaptosomes and glial cells by 90 and 75-80%, respectively.
