Effects of resveratrol on alterations in cerebrum energy metabolism caused by metabolites accumulated in type I citrullinemia in rats.

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
We investigated the in vitro effects of citrulline (0.1, 2.5 and 5.0 mM) and ammonia (0.01, 0.1 and 1.0 mM), and the influence of resveratrol (0.01 mM, 0.1 mM and 0.5 mM) on pyruvate kinase, citrate synthase, succinate dehydrogenase (SDH), complex II, and cytochrome c oxidase activities in cerebral cortex, cerebellum and hippocampus homogenates of 60-day-old male Wistar rats. Results showed that 2.5 and 5.0 mM citrulline decreased pyruvate kinase activity in cerebral cortex and, at a concentration of 5.0 mM, increased its activity in hippocampus. Additionally, 5.0 mM citrulline increased citrate synthase activity in the cerebellum of rats. Citrulline (5.0 mM) reduced complex II and cytochrome c oxidase activities in cerebral cortex and hippocampus. With regard to ammonia, at 0.1 and 1.0 mM, decreased complex II activity in cerebral cortex and at 1.0 mM decreased its activity in cerebellum and hippocampus. Ammonia (1.0 mM) also decreased cytochrome c oxidase activity in cerebral cortex and cerebellum of rats. Resveratrol was able to prevent most of the alterations caused by these metabolites in the biomarkers of energy metabolism measured in the cerebrum of rats. Data suggest that these alterations in energy metabolism, caused by citrulline and ammonia, are probably mediated by the generation of free radicals, which can in turn be scavenged by resveratrol.
