Relative change of light scattering. The change of ALDH scattering during 180 min after adding 1,10-phenanthroline at 42°C was calculated. The change of ALDH scattering in the sample without lens water-soluble fraction indicates for as 100% in the bar graph. The scatterings were measured on day 2 (white bar), day 4 (gray bar), and day 6 (black bar) following selenite or placebo administration. Bar represent mean values (n =9 lenses in each group) and error bars represent S.E. * indicates P < 0.05 for significant differences.
