title: [Effect of Ca2+ and gamma-aminobutyric acid on glutamate and glutamine oxidation by rat brain synaptosomes].
abstract: It was shown in vitro that Ca2+ addition induced inhibition of the synaptosomal respiration with glutamate and glutamine. The presence of GABA in the medium increased the inhibitory effect of Ca2+ on glutamine oxidation, but not on glutamate. GABA, by itself, had no influence on both glutamate and glutamine oxidation.
