[Effects of lithium hydroxybutyrate and vagotomy on respiratory arrest caused by systemic serotonin administration in rats].

The role of gamma-hydroxybutyric acid (GHBA) and gamma-aminobutyric acid (GABA) in the mechanisms of respiratory arrest after systemic serotonin administration has been studied in anaesthetized outbred male rats. Under normal conditions, serotonin (5-HT) administration (20 - 60 microg/kg, i.v.
