Ki67 immunohistochemistry demonstrates that amitriptyline prevents the loss of proliferating cells in subgranular zone and hilus of the dentate gyrus after irradiation (A-D). Statistical analysis shows that the number of Ki67 cells reduced significantly in Exp-C. Pretreatment and posttreatment with amitriptyline prevents the loss of Ki67-labeled proliferating cells (E). **P < .01 versus the normal control group, #P < .05 versus the experimental control group.
