Gamma-Aminobutyric acid (GABA) and GABAA agonists enhance stimulated release of [3H]norepinephrine [( 3H]NA) in several regions of the rat brain. In this study, the mechanisms by which GABA and GABAergic agonists augment potassium-stimulated release of [3H]NA from rat frontal cortical slices were examined. GABA enhanced potassium-stimulated [3H]NA release,(More)
As the genomes of mammalian species become sequenced and gene functions are ascribed, the use of differential gene expression (DGE) to evaluate organ function will become common in the experimental evaluation of new drug therapies. The ability to translate this technology into useful information for human exposures depends on tissue sampling that is(More)
Agents that enhance gamma-aminobutyric acid (GABA) neurotransmission can modulate certain effects of opioids, such as analgesia. In this study, the interaction between morphine and GABAergic agents on the release of [3H]norepinephrine ([3H]NE) from rat frontal cortical slices was examined. GABA (10(-4) M), enhanced potassium-stimulated [3H]NE release and(More)
