Increase of DCX-positive hippocampal neurons by oral administration of tomato, lemon and mixture extracts. (A) Representative images of DCX-positive neurons. Scale bars: young, old, tomato, lemon, mixture, 100 μm. (B) The average DCX-positive cells per section was calculated and represented as a bar graph (n = 8 mice per group). The administration of mixture extracts showed synergistic increment of DCX-positive cells compared to old mice. # p < 0.01 vs. young mice. * p < 0.05 vs. old mice. T: tomato, L: lemon, T + L: mixture of tomato and lemon.
