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

Figure 27 Dendritic terminals in synaptic contact with inner hair cells at the basal turn following administration of (A) artificial perilymph, (B) 50 mmol/L α-amino-3-hydroxy-5-methyl-4-isoxazolepropionate, or (C) 200 mmol/L α-amino-3-hydroxy-5-methyl-4-isoxazolepropionate. Swelling of the dendritic terminals was not observed after injection of artificial perilymph. Although swelling of the dendritic terminals was observed at both concentrations of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionate (AMPA), the extent of swelling was more pronounced with 200 μmol/L than with 50 μmol/L AMPA.
