Figure 8: Western blot analysis for nuclear factor E2related factor 2 and heme oxygenase1 expression at protein level. (a) Nuclear factor E2related factor 2, heme oxygenase1 and βactin expression where 1 control, 2 ethyl acetate fraction treated, 3 ultravioletB irradiated, 4 ultravioletB + silymarin (5 µg/ ml), 5 ultravioletB + 10 µg/ml ethyl acetate fraction, 6 ultravioletB + 20 µg/ml ethyl acetate fraction, 7 +30 µg/ml ethyl acetate fraction; densitometric analysis of nuclear factor E2related factor 2 (b); heme oxygenase1 (c); βactin (d). Results were analysed statistically by GraphPad Prism software version 2.0 using oneway ANOVA followed by Dunnett's and Tukey's posttest, *P < 0.05, **P < 0.01, ***P < 0.001
