Figure 9

Photomicrograph of hippocampus of different experimental groups: control group (a) and low TiO₂ dose group (b), illustrating normal hippocampal with its characteristic three layers, polymorphic 3, pyramidal 2, and molecular 1. High TiO₂ dose group (c), illustrating neuronal necrosis (black arrows), dilated blood vessel (), molecular layer (ML), and glial cells (red arrows). H & E staining 400x magnification.
