Effect of DMF on hippocampal neurons of rats (n = 5). A Representative images showing Nissl bodies in the hippocampal CA1 (× 100, Scale bar = 100 mm; × 400, Scale bar = 50 mm.); B Quantitation of pyramidal cells in the CA1 hippocampal region (\(\overline{x}\) ±s). The number of Nissl bodies at the same site in each group of rats under a field of view was counted; C The thickness of granular layer of CA1 region of the hippocampus; The average thickness of granular layer was measured at five random positions in CA1 of each slice in each group under the same field of view. ^**P < 0.01 compared with the control group; ^##P < 0.01 compared with the PTU group
