耳蜗

Cell therapy targeting regeneration of the cochlear fibrocytes may therefore be a powerful strategy to cure sensorineural hearing loss that cannot be reversed by current therapies, state Dr. Matsunaga and colleagues.

Matsunaga博士及其同事们说：&因此针对耳蜗纤维细胞再生的细胞治疗有可能会成为治疗当前难以治逆转的感音神经性聋的一个强有力的方法。&

Reverse transcription polymerase chain reaction and western blot were used to detect the COCH and POU3F4/brn4 gene's expression. To investigate in vitro characteristics of COCH gene's expession, two factors were introduced in the culture medium of spiral ligament type Ⅰ fibrocytes respectively. Firstly, phosphorothionate-modified antisense oligodeoxynucleiotides to POU3F4/brn4 mRNA was applied to study the regulation effects of POU3F4/brn4 to COCH gene transcription.

引入人工合成的针对POU3F4／brn4基因mRNA的反义硫代磷酸寡聚脱氧核苷酸，干扰耳蜗螺旋韧带Ⅰ型成纤维细胞POU3F4／brn4的表达，免疫印迹检测反义干扰细胞POU3F4／brn4蛋白条带的强弱，RT-PCR检测反义寡核苷酸干扰细胞COCH基因转录水平的变化，观察POU3F4／brn4对COCH基因的转录调控作用。

The effect of gentamicin on survival and neuritogenesis of cultured spiral ganglion cell from NIH mouse 1-5 days after birth was observed.Different doses (25,50 and 100 mg/L)of gentamicin were add to the medium of SGC,and cultured for 14 days.

为观察硫酸庆大霉素对培养的小鼠耳蜗螺旋神经节细胞的细胞生存数和细胞突起长度的影响，在单离培养的出生1～5 d的NIH小鼠SGC培养液中，加入不同浓度的硫酸庆大霉素(25，50，100 mg/L)。

Objective To explore the changes in gene expression in the inner ear of Wistar rats with iron deficiency hearing loss.

目的应用基因芯片研究铁缺乏致聋大鼠耳蜗膜性结构基因表达的改变。

Methods Fifteen healthy, female SD rats were employed in the experiment. Sensitized systematically with keyhole limpet hemocyanin, the animals were inoculated with the same antigen through cochlea basal turn into the labyrinth. Adminstrated 5-bromo-2′-deoxyuridine intraperitoneally, the rats were sacrificed and the temporal bones were harvested at 3, 7,14 day after labyrinth vaccination respectively. The frozen sections of the decalcified samples were dealt with H-E staining and immunohistohemical methods to investigate the cellular infiltration, BrdUrd and IgG positive cells in the ES.

选用SD大鼠15只，以钥孔虫戚血蓝蛋白（keyhole limpet hemocyanin，KLH）全身免疫后，经耳蜗底回钻孔以相同抗原进行内耳免疫，然后分别在内耳免疫后3、7和14 d腹腔注射溴脱氧尿嘧啶核苷（bromodeoxyuridine，BrdUrd）后处死动物，取颞骨经组织学处理制作冰冻切片，用免疫组织化学技术观察内淋巴囊的细胞浸润、增殖和IgG细胞的分布状况。

We used normal value of summating potential /action potential as 0.35 in EcoG.. In total 33 people (66 ears), SP/AP ratio was abnormal in 20 people (60.6%), 31 ears (47.0%).

耳蜗电图检查，加成电位和综合动作电位比值以0.35当作参考值，SP/AP比值大於0.35为异常。

Ito,et al reported that many surviving transplanted-NSCs migrate to reach cochlear hair cell on 28th day after transplanted into the cochlea of newborn rat,some of them took on the identical morphology of inner or outer hair cells and expressed Phalloidin.

Ito等实验表明大鼠海马来源的神经干细胞(neural stem cells，NSCs)移植入新生(P0，P2)大鼠内耳后4周，部分存活的NSCs迁移至耳蜗毛细胞表面，形态上与内、外毛细胞相似，并表达毛细胞标志物Phalloidin。

Biomedical instruments and applications, such as medical imaging scanners, the cochlear implant, pacemakers and hearing aids.

生物医学仪器及应用，如医学成像扫描仪，对人工耳蜗植入，心脏起搏器和助听器。

See, snakes don't have actual ears, at least not on the outside, but they do have fully-formed inner-ear systems, completewith a cochlea, the fluid filled bone that harvests sound.

瞧，蛇类没有真正的耳朵，至少外观上没有，但是他们拥有构造完善的内耳系统，连同充满液体、用来接收声音的骨头——耳蜗。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
