Contribution of reactive oxygen species (ROS) to genotoxicity of nitrobenzene on V. faba.

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
Nitrobenzene is an important organic intermediate widely used in industry that can be hazardous to the environment. In our previous study, nitrobenzene showed genotoxic effect on soybean and tobacco plants at concentrations in the culture medium higher than 10 mg/L. The genotoxicity of nitrobenzene has been hypothesized to be multifactorial and reflective of the generation of free radicals; however, the mechanism has not been fully elucidated. The aim of this study was to investigate the relationship between the induction of genotoxicity and the production of free radicals in young seedlings of V. faba exposed to nitrobenzene, nitrobenzene + Vitamin C, and the controls (distilled water or Vitamin C). Micronucleus and chromosome aberration assays performed on root and leaf tissue of V. faba seedlings exposed to nitrobenzene (25 mg/L) demonstrated genotoxic effects which were partly reduced by Vitamin C at 25 mg/L. Increases in lipid peroxidase, O2•-, H2O2, superoxide dismutase and catalase activities were also observed in these tissues along with an attenuation of their induction by Vitamin C. Concomitant occurrence of genotoxicity and the generation of free radicals that are attenuated in the presence of Vitamin C, a scavenger of cellular free radicals, indicate that reactive oxygen species may contributes to genotoxicity of nitrobenzene in V. faba. These results are valuable for further understanding the genotoxicity mechanism of nitrobenzene.
