Atorvastatin Prevents Cognitive Deficits Induced by Intracerebroventricular Amyloid-β1-40 Administration in Mice: Involvement of Glutamatergic and Antioxidant 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
Deposition of amyloid-β (Aβ) peptides into specific encephalic structures has been pointed as an important event related to Alzheimer's disease pathogenesis and associated with activation of glial cells, neuroinflammation, oxidative responses, and cognitive deficits. Aβ-induced pro-oxidative damage may regulate the activity of glutamate transporters, leading to reduced glutamate uptake and, as a consequence, excitotoxic events. Herein, we evaluated the effects of the pretreatment of atorvastatin, a HMG-CoA reductase inhibitor, on behavioral and biochemical alterations induced by a single intracerebroventricular (i.c.v.) injection of aggregated Aβ1-40 in mice. Atorvastatin (10 mg/kg/day, p.o.) was administered through seven consecutive days before Aβ1-40 administration. Aβ1-40 caused significant cognitive impairment in the object-place recognition task (2 weeks after the i.c.v. injection) and this phenomenon was abolished by atorvastatin pretreatment. Ex vivo evaluation of glutamate uptake into hippocampal and cerebral cortices slices showed atorvastatin, and Aβ1-40 decreased hippocampal and cortical Na(+)-dependent glutamate uptake. However, Aβ1-40 increased Na(+)-independent glutamate uptake and it was prevented by atorvastatin in prefrontal cortex slices. Moreover, Aβ1-40 treatment significantly increased the cerebrocortical activities of glutathione reductase and glutathione peroxidase and these events were blunted by atorvastatin pretreatment. Reduced or oxidized glutathione levels were not altered by Aβ1-40 and/or atorvastatin treatment. These results extend the notion of the protective action of atorvastatin against neuronal toxicity induced by Aβ1-40 demonstrating that a pretreatment with atorvastatin prevents the spatial learning and memory deficits induced by Aβ in rodents and promotes changes in glutamatergic and antioxidant systems mainly in prefrontal cortex.
