Fig. 4. (A) The number of cAMP responsive element binding protein (CREB) immunostained nuclei in different hippocampal CA1 and CA3 of the experimental groups. The values are presented as means S.E.M. ##p<0.01 vs. Normal group; **p<0.01 vs. MCT group, respectively. (B) Photographs showing the distribution of CREB-immunoreactive cells in the hippocampus of Normal group (a), MCT group (b), Krill-PS 50+MCT group (c) and Krill-PS 100+MCT group (d). Sections were cut coronally at 30 ㎛ and the scale bar represents 200 ㎛.
