Involvement of the α(1D)-adrenergic receptor in methamphetamine-induced hyperthermia and neurotoxicity in rats.

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
Methamphetamine (METH) is a psychostimulant that damages nigrostriatal dopaminergic terminals, primarily by enhancing dopamine and glutamate release. α₁-adrenergic receptor (AR) subtype involved in METH-induced neurotoxicity in rats was investigated using selective α₁-AR antagonists. METH neurotoxicity was evaluated by (1) measuring body temperature; (2) determining tyrosine hydroxylase (TH) immunoreactivity levels; (3) examining levels of dopamine and its metabolites; and (4) assessing glial fibrillary acidic protein (GFAP) and microglial immunoreactivity in the striatum. METH caused a decrease in dopamine and TH levels and induced hyperthermia which is an exacerbating factor of METH neurotoxicity. Concurrently, METH increased GFAP expression and the number of activated microglia. Pretreatment with prazosin, a nonselective α₁-AR antagonist, completely abolished METH-induced decrease in both dopamine and TH and caused a partial reduction in hyperthermia. Prazosin also prevented METH-induced increase in both GFAP expression and the number of activated microglia. In vivo microdialysis analysis revealed that prazosin, however, does not alter the METH-induced dopamine release in the striatum. The neuroprotective effects of prazosin could be mimicked by a selective α(1D) antagonist, BMY 7378, but not by selective α(1A) or α(1B) antagonists. These results suggest that the α(1D)-AR is involved in METH-induced hyperthermia and neurotoxicity in rats.
