Figure 3. Pirenoxine (PRX) ameliorated selenite- and calcium-induced lens protein turbidity. Turbidity was expressed as an optical density (OD) and was determined by spectroscopy at 405 nm for 4 days. *0.03, 0.1, and 0.3 μM PRX versus controls (selenite or calcium only) at p<0.05. A: Selenite-induced turbidity formation in terms of the absolute OD was plotted versus incubation days. B: Calcium-induced turbidity formation expressed as absolute changes in lens turbidity in terms of the OD from the baseline were plotted by incubation day.
