MicroRNA Dysregulation in the Hippocampus of Rats with Noise-Induced Hearing Loss

Figure 4

Comparison of hippocampal histology between control and noise group rats. Hematoxylin and eosin demonstrated pigmented (dotted arrows) and vacuolated (arrows) cells in the noise group rats compared to the control group. The Nissl staining of the CA3 region demonstrated neuronal cells of control and noise groups which did not show significant difference between groups.
