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

backgroundAlcohol consumption is associated with oxidative stress in multiple tissues in vivo, yet the effect of chronic alcohol intake on intestinal redox state has received little attention. In this study, we investigated the redox status of 2 major intracellular redox regulating couples: glutathione (GSH)/glutathione disulfide (GSSG) and cysteine (Cys)/cystine (CySS) in a rat model of chronic alcohol ingestion.

methodsSprague-Dawley rats were fed the liquid Lieber-DeCarli diet consisting of 36% ethanol of total calories for 6 weeks. Control rats were pair-fed with an isocaloric, ethanol-free liquid diet. Defined mucosal samples from the jejunum, ileum, and colon were obtained and analyzed by high-performance liquid chromatography (HPLC) for GSH and Cys pool redox status. Mucosal free malondialdehyde (MDA) was measured as an indicator of lipid peroxidation.

resultsIn the ethanol-fed rats, Cys and mixed disulfide (GSH-Cys) were significantly decreased in all 3 segments of intestinal mucosa. Free MDA was increased in jejunal but not in ileal or colonic mucosa. Chronic ethanol ingestion significantly increased mucosal GSH concentration in association with a more reducing GSH/GSSG redox potential in the jejunum, but these indices were unchanged in the ileum. In the colon, chronic ethanol ingestion increased oxidant stress as suggested by decreased GSH and oxidized GSH/GSSG redox potential.

conclusionsChronic alcohol intake differentially alters the mucosal redox status in proximal to distal intestinal segments in rats. Such changes may reflect different adaptability of these intestinal segments to the oxidative stress challenge induced by chronic ethanol ingestion.
