Reduced Formation of Oxidative Stress Biomarkers and Migration of Mononuclear Phagocytes in the Cochleae of Chinchilla after Antioxidant Treatment in Acute Acoustic Trauma
Figure 1
Average ABR threshold shifts at each frequency (0.5–8 kHz) 10 days after noise exposure. Hearing threshold shifts were found in both the noise exposure and the noise/treatment groups at all frequencies with greater shifts in the high frequencies (2–8 kHz). Compared to the noise exposure group, significant reductions in threshold shifts were found in the noise/treatment group at all frequencies. There are significant differences in the threshold shifts between the noise exposure and the noise/treatment groups at all frequencies, especially at high frequencies (***, **, and * indicate , and <0.05, resp. Error bars represent standard error of the means. Number of ears = 12 in each group).
