Central administration of p-hydroxyamphetamine produces a behavioral stimulant effect in rodents: evidence for the involvement of dopaminergic systems.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
RATIONALE AND
objectivesIt is well-known that amphetamine induces increased locomotor activity in rodents. We previously found that intracerebroventricular (i.c.v.) administration of p-hydroxyamphetamine (p-OHA), an amphetamine metabolite, increases synaptic dopamine (DA) levels in the striatum. In the present study, we investigated the effect of p-OHA on locomotor activity in rodents.
resultsIn mice, i.c.v. administration of p-OHA significantly increased locomotor activity in a dose-dependent manner. p-Hydroxynorephedrine, another amphetamine metabolite, did not increase locomotor activity. This effect of p-OHA was inhibited by pretreatment with nomifensine, a dopamine-uptake inhibitor, but not by fluoxetine, a serotonin-uptake inhibitor, or diethyldithiocarbamate, a dopamine-beta-hydroxylase inhibitor. Furthermore, we tested the effects of microinjections of p-OHA into the rat nucleus accumbens (NAc) on locomotor activity. Local infusion of p-OHA into the NAc significantly increased locomotor activity. As in mice, the increased locomotor activity induced by p-OHA microinjection into the NAc in rats was inhibited by nomifensine.
conclusionsThese data suggest that dopaminergic systems in the NAc may play important roles in p-OHA-induced locomotor activity in rodents.
