Gabapentin completely attenuated the acute morphine-induced c-Fos expression in the rat nucleus accumbens.

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
A growing body of evidence suggests the existence of a functional interaction between gabapentin (GBP)-morphine system. However, the neuro-anatomical sites and molecular mechanism of action of gabapentin-morphine interaction to prevent and reverse morphine side effects as well as enhancement of the analgesic effect of morphine is not clear. Therefore, we examined the combined effects of GBP-morphine on acute morphine-induced c-Fos expression in rat nucleus accumbens. The combined effect of GBP-morphine was examined by means of c-Fos immunohistochemistry. A single intraperitoneal injection (i.p.) of morphine (10 mg/kg), saline (control), and co-injection of GBP (150 mg/kg) with morphine (5 mg/kg) was administered under anesthesia. The deeply anesthetized rats were perfused transcardially with 4% paraformaldehyde 2 h after drugs administration. Serial 40 μm thick sections of brain were cut and processed by immunohistochemistry to locate and quantify the sites and number of neurons with c-Fos immunoreactivity. Detection of c-Fos protein was performed using the peroxidase-antiperoxidase detection protocol. The present study demonstrated that, administration of GBP (150 mg/kg, i.p.) in combination with morphine (5 mg/kg, i.p.) significantly (p < 0.01) attenuated the acute morphine (5 mg/kg, i.p.)-induced c-Fos expression in the rat nucleus accumbens shell. Present results showed that GBP-morphine combination action prevented the acute morphine-induced c-Fos expression in rat nucleus accumbens. Moreover, this study provides first evidence of neuro-anatomical site and that GBP neutralized the morphine-induced activation of rat nucleus accumbens shell.
