Polychlorinated Biphenyls-Induced Oxidative Stress on Rat Hippocampus: A Neuroprotective Role of Quercetin

Figure 9

Photomicrograph of the hippocampal pyramidal cell layers in Control, Quercetin, PCB, and PCB with Quercetin Treated rats. Histology of hippocampus in PCBs-exposed adult rats. Figures (a), (b), (c), (d) are 10x magnification, (e), (f), (g), and (h) are 40x magnification. The normal pyramidal cells (NPC) of hippocampal layer are normal in control rats (a) (e) and quercetin alone treated rats (b) (f). Degeneration of pyramidal cells is observed in PCB-treated rats (c) (10x). Degenerative neurons (DNs) as well degenerative layers are also observed in PCB-treated rats (40x) (g). Restoration of pyramidal cells in both 10x and 40x magnifications (d) (h) few degenerated pyramidal cells are also seen (d) (h). (Haematoxylin and Eosin staining 10x/40x).
