Attenuation of morphine analgesic tolerance by rosuvastatin in naïve and morphine tolerance rats.
Article in Inflammation, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
Recent studies suggested that statins have anti-inflammatory effects beyond their lipid-lowering properties. Since inflammation in the central nervous system was highly related to morphine tolerance, we sought to investigate whether statins could affect morphine tolerance by mediating glia-derived proinflammatory cytokines secretion. We have undertaken two separate studies: Firstly, we determined the effect of rosuvastatin on naïve rats during induction of morphine tolerance. Secondly, we investigated whether rosuvastation could attenuate the morphine analgesic tolerance in rats that the morphine tolerance established previously. Results demonstrated that peroral rosuvastatin not only delays, but also partially reverses the tolerance to morphine analgesia in rats. The administration of rosuvastatin during induction of morphine tolerance attenuated the activation of ERK and the release of proinflammatory cytokines in the lumbar spinal cord. Similar outcomes were observed in rats were morphine tolerance was established previously. Moreover, our study also found that repeated administration of morphine could activate the astrocytes in the spinal cord while rosuvastation succeeds in suppressing the activation of astrocytes. Our results support the idea that targeting glia-derived proinflammatory effects during morphine treatment is a novel and clinically promising method for enhancing analgesic effects of morphine. We identify a potential new application of statins in the treatment of morphine analgesic tolerance.
