Figure 4

Effects of luteolin (LUT, 50 mg/kg, orally) on the activity of superoxide dismutase (SOD; A), and catalase (CAT; B), glutathione peroxidase (GPx; C), and glutathione reductase (GR; D), and their mRNA expression in the liver tissue following lead acetate (PbAc, 20 mg/kg, i.p.). The biochemical data are expressed as the mean ± SD (n = 7). mRNA expression results are recorded as the mean ± SD of five assays in duplicate referenced to Gapdh and represented as fold changes (log2 scale) as compared with the mRNA levels of the control group. a represents the statistical significance relative to that of the control group at p < 0.05. b represents the statistical significance relative to that of the PbAc-injected group at p < 0.05. * reflects the statistical significant differences between groups at p-values < 0.01. Moreover, ** reflects the statistical significant differences between groups at p-values < 0.001.
