| TBARS (nmoles MDA/g tissue) | 6.87 ± 0.56 | 16.34 ± 0.63 | 9.81 ± 0.44∗ | 11.49 ± 0.51¥ |
| GSH (μmoles/g tissue) | 8.87 ± 0.46 | 5.78 ± 0.43 | 6.97 ± 0.24∗ | 7.43 ± 0.27¥ |
| CAT (μmol of H2O2 destroyed/min per mg protein) | 4.12 ± 0.54 | 2.12 ± 0.23 | 3.01 ± 0.12∗ | 3.74 ± 0.09¥ |
| SOD (U/mg protein) | 6.53 ± 0.45 | 3.85 ± 0.33 | 5.92 ± 0.1∗ | 6.15 ± 0.18¥ |

Values are expressed as mean ± SD of eight rats in each group. ∗p < 0.05 significant differences compared to controls; ¥p < 0.05 significant differences compared to the ISO group of rats.
