Effect of metformin on SOD and MDA levels in cultured HK-2 cells treated with oxalate. (a) MDA levels of HK-2 cells were treated with 1.6 mM sodium oxalate with or without 1 mM metformin for the indicated time points. (b) SOD activities of HK-2 cells were treated with 1.6 mM sodium oxalate with or without 1 mM metformin for the indicated time points. Values represent mean ± SD of 3 independent experiments. P < 0.05, versus control.
