1 · What the graph read from it

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.

2 · The registry

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

Curcumin exerts hepatoprotective effects via poorly defined mechanisms. Recently, some studies suggested that this effect was mediated by antagonizing CB1 receptors in hepatic stellate cells. The current study aimed to investigate whether CB1 antagonist, hemopressin, could potentiate the hepatoprotective effect of curcumin, in comparison with silymarin in bile duct-ligated (BDL) rats. Curcumin and hemopressin each alone and in combination ameliorated biochemical and structural fibrotic injury, and downregulated cyclooxygenase-2 (COX-2) and both mRNA and protein levels of nuclear factor kappa B (NF-κB) in fibrotic liver. In contrast to the previous studies, curcumin alone did not affect the gene expression of cannabinoid receptors. However, the combination of hemopressin and curcumin reduced the expression of CB1 in fibrotic liver. Surprisingly, silymarin upregulated CB2 receptors and downregulated CB1 at mRNA level more than all the administered drugs. Both curcumin and hemopressin each alone decreased lipid peroxidation product, malondialdehyde (MDA), while the combination increased the reduced glutathione content. All the administered drugs increased the hepatic antiapoptotic marker, Bcl2. Our study suggests that hemopressin potentiates the hepatoprotective effect of curcumin on fibrotic liver. We identified a new mechanism of the hepatoprotective effect of silymarin via modulation of cannabinoid receptors in fibrotic liver.
