  1. Immune cells (B, T, NK, myeloid cells, macrophages, and neutrophils) population in the control and noise- exposed cochleae has been shown as the percentage population of the total CD45 + cells. Percentage population of CD45 + cells are from the total pool of live lymphocytes in the cochleae. Data are shown as mean ± SEM. A p value of < 0.05 was considered as significant. All the p values shown here are compared to control cochleae. *Control vs days. M male, F female, NS not significant.
