The effect of ginsenoside Rg1 on the cell distributions in DG area of hippocampus in brain-aged rats.

The immunofluorescence of β-tubulin III (for neuron), GFAP (for astrocyte) Gal-C (for oligodendrocyte) and BrdU (for newly generated cell) was carried out on the slides. The numbers of marked cells were estimated on three randomly selected sections taken through the central extent of the dentate gyrus area. The experiments were performed three times with similar results. Data are expressed as mean ± SD. Different letters represent significantly different values as assessed by ANOVA and LSD tests with P<0.05.
