Social behavior and neuronal activation in adolescent female Fos-LacZ transgenic rats: Impact of acute ethanol challenge and baseline levels of social preference.

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
In human adolescents, females often report drinking for coping reasons to avoid negative affective states. We have shown previously that adolescent female rats with elevated levels of anxiety-like behavior under social test circumstances, indexed via low social preference are sensitive to anxiolytic effects of ethanol given intraperitoneally (ip) in a low-to-moderate dose range. This study was designed to test the hypothesis that patterns of neuronal activation across brain regions implicated in social activity and social preference (used as an index of low versus high anxiety-like social responding) would be affected by acute ethanol differently in adolescent females with high and low social preference, with initial levels of social preference also predicting ethanol-induced changes in social behavior. Adolescent female Fos-LacZ rats were given social interaction tests on postnatal day (P)33 for determination of baseline levels of responding to an unfamiliar social partner and on P35 following administration of 0 or 0.75 g/kg ethanol. Brain tissue was collected, and expression of β-galactoside (β-gal) was used as an index of neuronal activation. Baseline levels of social preference did not predict social responsiveness to an acute ethanol challenge, whereas significant decreases in this social measure that reflects anxiety-like behavioral alterations were evident in adolescent females challenged with ethanol relative to saline-injected controls, suggesting high sensitivity to the anxiogenic effects of ethanol. Ethanol precipitated negative relationships between social preference and prefrontal cortical activation, decreased neuronal activation of the anterior cingulate cortex, but substantially increased β-gal expression in the central amygdala. These results suggest high sensitivity of the prefrontal cortical regions and central amygdala to ethanol-induced alterations in adolescent Fos-LacZ females and provide a background for further phenotyping of neurons activated by ethanol under social test circumstances.
