Could somebody explain what this means?: d-amphetamine sensitization abstract

[Sloop]

I know the following abstract is for rats and not humans, but if it did apply to humans does it mean taking gingko with d-amphetamine is a good thing or bad thing?

I cant seem to get my head around what the fuck it could mean, that is if it turns out it applies to people as well?
Could somebody decipher it into street English for me please?

Abstract

Pretreatment of rats with the extract of Ginkgo biloba termed EGb761 reduced the behavioral sensitization induced by successive D-amphetamine administrations (0.5 mg/kg) as estimated by increasing values of locomotor activity. EGb761 pretreatment also prevented the reduced density of [[3]H]dexamethasone binding sites in the dentate gyrus and the CA1 hippocampal regions of D-amphetamine treated animals. These observations suggest that EGb761, by reducing glucocorticoid levels, could modulate the activity of the neuronal systems involved in the expression of the behavioral sensitization.
