Experimental study of transient cochlear ischemia as a cause of sudden deafness

Figure 23 Immunostaining of the organ of Corti and the spiral ganglion for inducible nitrous oxide synthase before and 1, 4, and 7 d after ischemia. Immunostaining for inducible nitrous oxide synthase was observed in the inner hair cells, spiral ganglion cells, and spiral limbus on days 1 and 4. It was obviously decreased on day 7, but the synaptic area underneath the outer hair cells and the spiral ganglion cells was still positively stained. Originated from[17], with permission.
