Photomicrographs of COX-2 IR in left and right hippocampi 3 days after 3 hours of SD. A,B: Low-power photomicrographs of left (A) and right (B) hippocampi taken at × 15. As confirmed by statistical analysis of optical density (Fig. 8), induction of COX-2 IR was greater in the dentate gyrus C,D than in CA3 E,F. Induction of COX-2 in CA3 was greater than in CA1 (G,H). Photomicrographs C–H were taken at × 150. Scale bars = 400 μm in A,B, 15 μm in C–H.
