Effect of metformin on SOD and MDA levels in cultured MDCK cells treated with oxalate. (a) MDA levels of MDCK cells were treated with 1.6 mM sodium oxalate with or without 8 mM metformin for the indicated time points. (b) SOD activities of MDCK cells were treated with 1.6 mM sodium oxalate with or without 8 mM metformin for the indicated time points. Values represent mean ± SD of 3 independent experiments. ; , versus control.
