Abstract:Objective to analysis the auditory brainstem response(ABR)wave characteristics of normal-hearing mini-pig, and compare with the human. Methods 15 normal-hearing minipigs to be selected and tested by click and tone burst stim-ulus respectively in P10、P30 and P60, and record the datas. Results①Minipig can differentiate 7 waves, of which the waveⅤis the most distinguished and the symbol of threshold, the value of which is 25-30dB SPL , and auditometry frequencies ranges from 1 to 48 kHz of which the most sensitive frequency is 2kHz;②the minipig’s ABR latencies of waveⅠ、Ⅱ、Ⅳ、Ⅴand interpeak latency ofⅡ-Ⅴare separately 1.53 ± 0.18、2.60 ± 0.16、3.36 ± 0.22、4.76 ± 0.21、2.16 ± 0.14(ms)in P10, 1.68 ± 0.23、2.79±0.33、3.47±0.32、4.97±0.32、2.17±0.30(ms)in P30, and 1.71±0.22、2.74±0.23、3.45±0.25、4.82±0.22、2.08±0.23 (ms)in P60;both latencies of P30、P60 are longer than the P10, but the latency of P60 is shorter than P30;and there’s a sig-nificant difference between P10 and P30, but not between P10 and P60;③the ABR latency and amplitude of miniature pig’s between bilateral ears are slight differences, which also have no significance. Conclusions the ABR waves of minipig are simi-lar to human, and may derive from the same resources;hence, we can take advantage of animal models of human’s disease by use of minipig.
