Changes in zinc and manganese concentrations in cisplatin-induced acute kidney injury.

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
Cisplatin (CDDP) is a widely used anticancer drug, but acute kidney injury (AKI) is one of the most important dose-limiting factors. Trace metal elements are present in various concentrations in the body and play an important role in maintaining normal vital functions. However, the relationship between CDDP-induced AKI and trace metal elements is unknown. In this study, we cultured human renal proximal tubular epithelial cells in the presence of CDDP (0, 12.5, 25, 50 μM) and analyzed the concentration of trace elements in medium after 24 h. We found that CDDP significantly increased the concentrations of zinc (Zn) and manganese (Mn) in medium and significantly decreased them in lysate. Therefore, we examined the effects of CDDP (3 mg/kg, i.p.) administration on serum and urinary Zn and Mn concentrations in rats. The results showed that urinary excretion of Zn and Mn increased in CDDP-treated rats 5 days after administration. Also, 5 days after administration, pyknosis, nuclear loss, loss of the brush border membrane, and DNA fragmentation were observed, and serum creatinine and blood urea nitrogen levels were found to be significantly increased. These data suggested that 24-h excretion of Zn and Mn might reflect on CDDP induced nephropathy. Monitoring urinary Zn and Mn excretion may be beneficial in detecting AKI, but further studies are needed for clinical application.
