Experimental acute arsenic toxicity in Balb/c mice: organic markers and splenic involvement

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
Introduction: Arsenic is an environmental toxic present worldwide. In men and animals, various organs and tissues are targets of its deleterious effects including those of the immune system. Objective: To determine acute arsenic toxicity in tissues and target cells of Balb/c mice using an in vivo methodology. Materials and methods: We injected Balb/c mice intraperitoneally with 9.5 or 19 mg/kg of sodium arsenite (NaAsO2), or an equivalent volume of physiological solution as a control (with 3 per experimental group). After 30 minutes, the animals were sacrificed to obtain spleen, thymus, liver, kidneys, and blood. We determined arsenic, polyphenols, and iron concentrations in each sample and we evaluated the oxidative markers (peroxides, advanced products of protein oxidation, and free sulfhydryl groups). In splenocytes from the spleen, cell viability and mitochondrial potential were also determined. Results: The exposure to an acute dose of NaAsO2 reduced the mitochondrial function of splenocytes, which resulted in cell death. Simultaneously, the confirmed presence of arsenic in spleen samples and the resulting cytotoxicity occurred with a decrease in polyphenols, free sulfhydryl groups, and an alteration in the content and distribution of iron, but did not increase the production of peroxides. Conclusion: These findings provide scientific evidence about changes occurring in biomarkers involved in the immunotoxicity of arsenic and offer a methodology for testing possible treatments against the deleterious action of this compound on the immune system.
