Selective Vulnerability of the Cochlear Basal Turn to Acrylonitrile and Noise
Figure 4
Average cochleograms
showing hair cell loss in rats exposed to (a) ACN alone or to the 110 dB
OBN-4 kHz with (c) or without (b) ACN, in rats exposed to the 97 dB OBN-8 kHz with
(e) or without (d) ACN, and in rats exposed to the 97 dB OBN-16 kHz with (g) or
without (f) ACN. Abscissa (i) upper trace: length (mm) of the entire spiral
course of the organ of Corti from the bottom of the hook, (ii) lower trace:
frequency-map according to Muller [9]. Ordinate: hair cell loss in
percent. IHC: inner hair cells; OHC1: first row of outer hair cells; OHC2:
second row; OHC3: third row. Error bars represent the standard error.
