Expression changes of ARs in rats exposed to noise and controls. a A schematic diagram illustrating the experimental procedure. b Western blot showing the expression changes of ARs in rats exposed to noise and controls (n = 6). c Quantification of the western blotting results. *p < 0.05, **p < 0.01. d Representative images showing DBH immunostaining at different positions along the base-to-apex axis. Rows and columns correspond to different positions along the cochlear axis, respectively, as indicated. Scale bar: 50 μm. e-f Representative images showing α2A-AR immunostaining at Organ of Corti and SGNs. Scale bar: 50 μm
