Cr (B) induced MDA formation at all concentrations tested. At the low dose, MDA returned to control levels over time. However, at the medium and high doses of Cr, MDA levels were elevated for the duration of the experiment. Data are expressed as mean ±SE, n = 6–7 animals per group. *Significantly different from control on each day, <i>p</i><0.05.</p> 2015-05-19 03:09:37 1 day post exposure candidate biomarkers oh ros Chromium Exposure U.S Rat Liver Gene Expression Cr levels DNA strand breaks
