Table 2. Activities of antioxidant enzymes of the lenses of each group.

Enzyme	Group I	Group II	Group III
Superoxide dismutase (unit/ml)	0.37±0.07	0.18±0.05**	0.26±0.03^{#, ‡}
Catalase (nmol/min/ml)	0.07±0.01	0.04±0.005*	0.067±0.02^‡
Glutathione peroxidase (μmol glutathione oxidized/min/mg tissue)	14.71±1.39	7.39±1.30**	12.34±1.93^†

Activities of the enzymes superoxide dismutase, catalase and glutathione peroxidase of the lenses of each experimental group. Group I: Control, Group II: Selenite-treated, Group III: Selenite+Saffron-treated. Each value represents the mean ± SD of six determinations. Statistical analysis was performed by one-way ANOVA with Bonferroni’s adjustment . Different symbols indicate statistically significant difference between groups of each enzyme activity. *p<0.01; **p<0.001; ^#p<0.05 compared with group I. ^‡p<0.05; ^†p<0.001 compared with group II.
