(a) COX-2 immunoreactivity (arrow) was detected in many cells throughout the hippocampus, especially in the dentate gyrus (DG). The COX-2 positive cells appeared unregulated in the epilepsy-only and epilepsy-celecoxib groups at 14 d after SE, compared with the normal control group; (b) C-Fos immunoreactivity (arrow) was detected in many cells throughout the hippocampus, especially in the dentate gyrus (DG). The c-Fos positive cells appeared up-regulated in the epilepsy-only and epilepsy-celecoxib groups at 14 d after SE, compared with the normal control group
