Figure 1: Pathological changes in hippocampus CA1 among the groups (H and E, ×400, ×400, bar = 20 μm). Hematoxylin and eosin sections of brain tissues showed normal morphology in sham group, edema, eosinophilic degeneration and karyopyknosis of nerve cells could be seen in model group and treatment groups (arrows). (1) Sham. (2) Model. (3) Astragaloside IV. (4) Ginsenoside Rg1. (5) Ginsenoside Rb1. (6) Notoginsenoside R1. (7) Four active components combination. (8) Edaravone
