Figure 1 Generation of 8-OHdG in the brain tissues of male rats treated with Hyphaene thebaica extract with/or after AD induction. DNA damage was expressed as the ratio of oxidized DNA base (8-OHdG) to nonoxidized base (2-dG) in brain DNA. Data are presented as mean±SEM. a, b, c: mean values within column with unlike superscript letters were significantly different (aP<0.001, bP<0.01, dP<0.05). AD, Alzheimer’s disease; 2-dG, 2-deoxy guanosine; 8-OHdG, 8-hydroxy-2-deoxyguanosine.
