Effect of PPVL and bilirubin on antioxidant enzyme activities (mean ± SE)
| Group | Catalase (pmol/mg protein) | Total superoxide dismutase (U/mg protein)1 | Glutathione peroxidase (U/mg protein)2 |
| Sham | 10.5 ± 1.1a | 9.0 ± 0.2b | 0.129 ± 0.004a |
| PPVL | 6.5 ± 0.5 | 4.5 ± 0.1 | 0.100 ± 0.004 |
| Sham + Bilirubin | 10.7 ± 0.9a | 9.3 ± 0.1b | 0.132 ± 0.006a |
| PPVL + Bilirubin | 9.4 ± 0.9a | 8.9 ± 0.2b | 0.131 ± 0.004a |
Enzymatic activities were assayed as described in the text.
1
One unit of SOD activity is defined as the amount of enzyme required to inhibit 50% of the epinephrine autooxidation.
2
One unit of the enzyme represents the decrease of 1 mmol of NADPH/min under the assay conditions.
a
P < 0.05 between Catalase and Glutathione Peroxidase of Sham groups, PPVL + Bilirubin and PPVL group,
b
P < 0.01 between Superoxide Dismutase of group of Sham groups, PPVL + Bilirubin and PPVL group and PPVL group according to Neuman-Keuls' test.
