Protective Effect of Yang Mi Ryung® Extract on Noise-Induced Hearing Loss in Mice

Figure 1

Experimental scheme of animal study. Mice were divided into four different groups after initial ABR was measured: Cont, noise, YMRE, and YMRE + noise. For groups with YMRE treatment, mice were administered orally with a dose of 100 mg/kg/day for 5 weeks, while sterile DW (s-DW) was given to mice groups that were not treated with YMRE. After 5 weeks of treatment with either s-DW or YMRE, ABR was measured prior to and on days 1, 5, and, 10 after exposure to 100 dB noise (YMRE: Yang Mi Ryung extract, ABR: auditory brainstem response).
