Figure 2. — Hematoxylin and eosin of hippocampus and frontal cortex. (A) Cells in dentate gyrus show normal arrangements and distributions in the sham group. (B) Slight hippocampal changes in the NS-injected rats including neuronal degeneration, nuclear pyknosis and granule cells proliferation. (C) Hippocampal changes in the FeCl₂-injected rats including plenty of neuronal loss, swelling, degeneration and death, as well as inflammatory cell infiltration and glial cell proliferation. (D) Cells in frontal lobe show normal arrangements and distributions in the sham group. (E) Slight cellular changes in frontal lobe of the NS-injected rats including neuronal degeneration, nuclear pyknosis and granule cells proliferation. (F) Cellular changes in frontal lobe of the FeCl₂-injected rats including plenty of neuronal loss, swelling, degeneration and death, as well as inflammatory cell infiltration and glial cell proliferation. Bottom graphs are enlarged view of the boxs above (magnification, ×400), respectively. NS, normal saline.
