Abstract:
:The activities of GABA-transaminase (GABA-T) were examined in several brain regions of amygdala-kindled rats, pretreated either with or without gabaculine, an irreversible GABA-T inhibitor. Histochemical and biochemical studies demonstrated that GABA-T activities decreased significantly in some brain regions 16 h after the gabaculine treatment. In contrast, no such alteration was detected in kindled animals after a 48-h survival period either with or without the pharmacological manipulation. The present results suggest that kindling causes retardation of GABA-T resynthesis in neurons, since the GABA-T activities detected 16 h after the drug treatment are due to newly synthetized enzyme in presumptive GABA neurons but not glial cells.
