Nissl staining results in each group. A Representative Nissl-staining of CA1, CA2 and DG area in each group, B Number of neurons at CA1 area in each group, C Number of neurons at CA2 area in each group, D Number of neurons at DG area in each group. n = 6. Old SHR-C indicates old SHR control group, Old SHR-L indicates old SHR treated with low dosage of Gao-Zi-Yao, Old SHR-M indicates old SHR treated with medium dosage of Gao-Zi-Yao, Old SHR-H indicates old SHR treated with high dosage of Gao-Zi-Yao. *P < 0.05 old SHR-M, and old SHR-H compared with old SHR control group
