Fig. 2From: Dendropanax morbifera Léveille extract ameliorates cadmium-induced impairment in memory and hippocampal neurogenesis in ratsImmunohistochemistry for Ki67 in the dentate gyrus of treated rats. Ki67 immunostaining in rats treated with vehicle (a), Dendropanax morbifera Léveille stem extract (DMS; b), cadmium alone (Cd; c), cadmium and DMS (Cd-DMS; d), and cadmium plus galantamine (Cd-GAL) (e). In the vehicle-treated group, Ki67-positive nuclei (arrows) are detectable in the subgranular zone of the dentate gyrus. Note that there are few Ki67-positive nuclei in the Cd-treated group; however, they are comparatively abundant in the Cd-DMS-treated and Cd-GAL-treated groups. GCL, granule cell layer; ML, molecular layer; PoL, polymorphic layer. Scale bar = 100 μm. f: Quantitative analysis of Ki67-positive nuclei per section in the vehicle, DMS-treated, Cd-treated, DMS-Cd-treated, and DMS-GAL-treated rats using an image analyzer (n = 5 per group); * indicates a significant difference between the vehicle and Cd groups (p < 0.05); # indicates a significant difference between the vehicle and DMS (or GAL) groups (p < 0.05; n = 5 per group). The data are shown as mean ± SEMBack to article page
