Numbers of outer hair cells in MDL- and vehicle- treated animals. Left ears were locally applied drugs. A: Numbers of inner hair cells (IHC) in left (L) and right (R) cochleae of MDL-treated animals. B: Numbers of IHC in left (L) and right (R) cochleae of vehicle-treated animals. C: Numbers of outer hair cells (OHC) in left (L) and right (R) cochleae of MDL-treated animals. D: Numbers of OHC in left (L) and right (R) cochleae of vehicle-treated animals. The difference in OHC numbers between left and right in vehicle-treated animals was statistically significant at p < 0.05 with paired t-test (*). E: Increasing numbers of OHC in MDL- and vehicle-treated cochleae. The difference in increasing OHC numbers between MDL- and vehicle-treated cochleae was statistically significant at p < 0.05 with unpaired t-test (*).
