Apoptotic index of the retina of rats treated with (-▪-) or without (-♦-) 1% BRACs for 15 days and exposed to light for 0~24 h. Values are the means for seven rats at each time point, with standard deviations represented by vertical bars. ^*Mean value was significantly different compared with the same light exposure time in rats not treated with BRACs (p < 0.05, t test). ^a,b,cMean values with different letters on the same curve at different exposure times were significantly different (p < 0.05, Ryan's multiple range test).
