摘要
利用客观电反应测听和主观电测听两种方法,观察了14名18岁～25听力正常的男女自愿受试者肌内注射催产素20u/人前后听力的变化。结果表明,注射催产素后,在以8 KHz click 诱发的听觉脑干诱发电位 V 波阈值为指标的客观测听中,有27耳听阈明显下降;在以0,5K、1K、2K、4K 和8KHz 纯音主观测听中,有14耳听阈明显下降。此种变无性别差异。结果提示,外源性催产素能提高正常人的听力。
Changes of hearing thresholds were observed before and after administration of oxytocin(OXT)by both objective acoustic brainstem evoked response(ABR)and subjective electro-audiometry in the normal ears of 14 volunteers aged 18～25 years. After administration of OXT(20 U/subject,i.m.)the thresholds were decreased in 27 ears using the thresholds of ABR‘V’wave induced by 8 KHz click as objective index of auditory function,and a marked decrease of thresholds was found in 14 ears confirmed by 0.5,1,2,4,and 8 KHz subjective pure tone hearing test.There are no differences between the male and female.The results demonstrate that OXT may increase the human auditory function.
