Lead Induced Ototoxicity and Neurotoxicity in Adult Guinea Pig

Figure 2

Representative confocal photomicrographs of normal control and lead exposure groups. The OHCs and IHCs were stained with Alexa 488-labeled phalloidin (green). The number and shape of three rows of OHC and one row of IHC appeared normal in the basilar membrane from apical turn to basilar turn in 0 d, 15 d, and 30 d group. Only few OHC appeared missing in 60 d and 90 d group. OHC: out hair cells; IHC: inner hair cells. Scale bar: 20 μm.
