Microscopic appearance of cerebral cortex stained with H & E. Histopathology of cerebral cortex (×10) in rats 4 weeks post-exposure to different concentrations of ZALH (A), ZALL (B), ZAH (C), ZAL (D) and vehicle control (E). The H & E stained micrographs showing cerebral cortex layers (CL), many neuronal cells and blood vessel (BV) on micrograph (E). Similar structural appearances were noted on all the four treated groups (A to D), thus no changes were seen in the cerebral cortex of the treated animals compared to control.
