Figure 4.

Effects of olive leaf extract (OLE) treatment on superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), and glutathione reductase (GSH-R) activities and their corresponding mRNA expression in the testis of rats treated with cisplatin (CDDP). Data of antioxidant enzyme activities are expressed as the mean ± SEM (n = 7), whereas mRNA expression data are expressed as the mean ± SEM of triplicate assays, normalized to the GAPDH mRNA level, and shown as fold change (in log2 scale) relative to the control mRNA levels. ^aSignificant change from the control group at p < 0.05; ^bsignificant change from the CDDP group at p < 0.05 using Tukey's post hoc test.
