Effect of Cr and NAM pretreatment on SOD activity. DHF cells were exposed to various concentrations of Cr or NAM alone or combined, media alone (SHAM), or water vehicle (1%). Twenty-four hours later, the cells were exposed to 600 µM H₂O₂ for 30 min. SOD Assay kit-WST (Dojindo) was used measure SOD activity at that time. The data are mean ± SE from duplicate experiments using triplicate samples. * Denotes statistically significant changes in the Cr/NAM treated levels in comparison to H₂O₂ alone.
