CAT-SKL reduces lipid hydroperoxide levels and increases catalase activity in tissue. (A) Lipid hydroperoxide levels were measured in mouse livers (n = 4) using the lipid hydroperoxide assay kit as described in the Materials and Methods. (B) Catalase activity was measured enzymatically in mouse liver as described in the Materials and Methods. Error bars represent mean ± SEM for quadruplicate samples. Means designated by different letters are significantly different (P < 0.05) according to Tukey's multiple comparison test.
