Effect of AE and NDGA on antioxidant enzymes activity (a and b) and on antioxidant enzymes expression (c and d) in submandibular glands of STZ- treated rats. Western blots are representative of three experiments. Results represent Mean ± SEM of three determinations made in duplicate. * P < 0.05, ** P < 0.01 significant differences between submandibular glands from normal control and submandibular glands from STZ-treated animals. # P < 0.05, ##P < 0.01 significant differences between glands from STZ and STZ + AE or NDGA-treated glands (ANOVA+ Dunnett’s test). AE: 500 μg/ml, NDGA: 1.5 μg/ml
