Exposure to Low Dose of Cinnabar (a Naturally Occurring Mercuric Sulfide (HgS)) Caused Neurotoxicological Effects in Offspring Mice

Figure 6

Chronological change of hearing thresholds and the absolute and the interwave latencies of ABRs waveforms in offspring mice treated with cinnabar. Offspring mice were orally gavaged with either cinnabar (10 mg/kg/day) or distilled water as described in Figure 1. The hearing thresholds (a), absolute wave (I, III, and V) (b), and the interwave latencies (I–III, I–V, and III–V) (c) of ABRs waveforms were recorded as described in Materials and Methods. Data are presented as mean ± SE (𝑛= 12–15/group). *𝑃<0.05 as compared with F1-C-V group; ^&𝑃<0.05 as compared with F1- or F2-Cin-V group; ^#𝑃<0.05 as compared with F1-C-Cin group, respectively.
