The relative AP-1, c-jun, (A) mRNA expressions normalized for corresponding GAPDH levels in retinas of rats treated with (-▪-) or without (-♦-) 1% BRACs for 15 days and exposed to light for 0 ~ 24 h. The semi-quantitative densitometry of Caspase-1 (B) protein expressions normalized for 0 h light levels without BRACs (set as 1) in retinas of rats treated with (-▪-) or without (-□-) 1% BRACs for 15 days and exposed to light for 0~24 h. Values are the means for three determinations with their standard deviations shown by vertical bars for each time point. ^a,b,cMean values with unlike letters on the same curve or among the same diet group at different exposure times were significantly different by Ryan's multiple range test (p < 0.05).^*Mean value was significantly different from that for rats at the same light exposure time treated but not treated with BRACs (p < 0.05, t test).
