CV staining in the hippocampal formation of gerbils at different time after 5- and 15-min BCCAO.

(A) Sham operation; (B) 1 day after BCCAO, (C) 2 days after BCCAO, (D) 5 days after BCCAO. CV-stained cells are not changed in all subregions in the hippocampus at 1 day after BCCAO. At 2 days after BCCAO, CV staining is markedly weakened in the PL of the CA1 region of gerbils from the 15-min BCCCAO group. Five days after BCCAO, CV-stained cells are decreased in number in the PL of the CA1 region of gerbils from the 5-min BCCAO group. The numbers of CV-stained cells in the 15-min BCCAO group were reduced in the PL of the CA1–3 regions. In the DG, changes in the number of CV-stained cells are detected only in the 15-min BCCAO group. Scale bars: 400 µm (Aa, Ba, Be, Ca, Ce, Da, De) and 100 µm (Ab–Ad, Bb–Bd, Bf–Bh, Cb–Cd, Cf–Ch, Db–Dd, Df–Dh). CV: Cresyl violet; BCCAO: bilateral common carotid artery occlusion; PL: pyramidal layer; DG: dentate gyrus; GCL: granule cell layer; ML: molecular layer; OL: oriens layer; PoL: polymorphic layer; RL: radiant layer; min: minute.
