Degree of lens opacification was observed and determined based on a scale 0 to 6 according to [24] on PN day 16. Group 1: normal control, Group 2: selenite-treated, Group 3: Selenite/Curcumin-treated (80 mg/kg), Group 4 to 6: Selenite/P.D bark extract-treated (40, 80, 120 mg/kg, respectively) animals. The Mann–Whitney U-test was performed for pair wise comparisons. ###p<0.001 significant different from group 1. *p<0.05, **p<0.01, ***p<0.001 significant different from group 2. ¥¥p<0.01, significant different from group3.
