Quantification of basilar membrane macrophages from four samples. Amoeboid macrophages were defined as dense, round cells without dendrites. Mature macrophages were defined as long, irregular shapes with dendrites. Cells in the basal turn (up to 60% of the distance from the apex) were counted. Two-way analysis of variance with the post-hoc Dunnett comparison was used to evaluate cell count differences from control cochlea. CTR, untreated cochlea; N1d, 1 day after noise exposure; N3d, 3 days after noise exposure; N5d, 5 days after noise exposure; N7d, 7 days after noise exposure. **P<0.01, ***P<0.001.
