title: One stressful event blocks multiple actions of diazepam for up to at least a month.
abstract: Based on recent findings of this laboratory, the hypothesis was tested that a single stressful encounter might have a persistent antidiazepam influence. Our results indicate that one exposure to a brief stressful event up to at least one month earlier prevented completely the effect of diazepam on pentylenetetrazole-induced changes in dopamine in the rat frontal cortex, elevations of plasma corticosterone levels and seizures.
