[Effect of D-, M- and T-antagonists of serotonin on its absorption by human thrombocytes].

Serotonin M-antagonist -- cocaine, and D-antagonist -- dihydroergotamine depressed the serotonin absorption by guman platelets considerably (in a concentration of 10(-4) by 90 and 62%, respectively). Serotonin M-antagonist--morphine, D-antagonist--deseryl, and T-antagonist--typindol inhibited serotonin absorption much less (in a concentration of 10(-4)M by 33, 28 and 18%, respectively). It is supposed that "serotonin" centre of the membrane carrier participating in the process of transmembrane serotonin transport was not identical to any definite type of serotonin receptor.
