Fig 3

A. Latency of the step-down avoidance task in each group. B. Number of NeuN-positive cells in each group. C. Photomicrographs of NeuN-positive cells in the hippocampal CA1 region. The scale bar represents 50 μm (left) and 200 μm (right). (□) Area of magnification at 200 μm in CA1 region. Sham, sham-operation group; CI, cerebral ischemia-induced group; CI-PDRN, cerebral ischemia-induced and polydeoxyribonucleotide (PDRN)-treated group; CI-PDRN+DMPX, cerebral ischemia-induced and PDRN with 7-dimethyl-1-propargylxanthine (DMPX)-treated group. * indicates P < 0.05 compared with the sham-operation group. # indicates P < 0.05 compared with the cerebral ischemia-induced group.
