Morphologic changes of hippocampus stained by Nissl staining using a light microscope (magnification 400×) and counting the results. The red arrow shows the normal nurons, and the black arrow shows the degenerated neurons.n=10, values are expressed as the mean ± SD. Bars without a common superscript letter differ significantly (P<0.05). a Photomicrographs of the CA1 obtained via Nissl staining. b Photomicrographs of the CA3 obtained via Nissl staining. The number of neurons per field in regions CA1 (c) and CA3 (d) of hippocampus. HCA1 = 57.007, P = 0.000; HCA3 = 62.606,P = 0.000
