[A clinico-biological study of the thrombocyte serotonin-transport complex in therapeutically resistant patients with endogenous depression undergoing combined treatment].

The platelet parameters of the functional status of the serotonin-reuptake complex were studied in drug-resistant depressive patients given various regimens of complex therapy or selective serotonin re-uptake inhibitors (fluvoxamine and fluoxetine). The most persistent and marked clinical effect was seen in electroconvulsive therapy and it was due to the normalization of the serotonin-reuptake system.
