Cytotoxic effect ERW-medium on U937 cells line. Cells were grown in an MQ-medium or MQ-NaOH medium or ERW-medium with/without H2O2 and subjected to an MTT assay to analyse cell cytotoxicity. Data is presented as means ± SD for triplicate experiments. * p < 0.05 vs. MQ-NaOH; ** p < 0.05 vs. MQ-NaOH + H2O2.
