耳囊

（1） In common cavity malformation, in addition to the abnormal bony labyrinth such as the cochlea, vestibule and lateral semicircular canal, the inner ear perceptive organ such as the saccule, utricle and scala media were also abnormal.（2） Though we could not identify the basal membrane and sensory epithelia under micro-endoscopy, the utricle and saccule could be clearly identified.（3） During cochlear implantation in common cavity malformation, electrode insertion should be monitored under micro-endoscopy, the electrodes should be put close to the anterior wall of the cavity, otherwise the vestibular organ may be damaged.

（1）共同腔畸形极重度聋患者不仅前庭、外半规管和耳蜗的骨性结构形态发生了变化，而且腔内耳蜗中阶与前庭的球囊、椭圆囊的膜迷路结构形态也发生了变化；（2）微窥镜下分辨不出基底膜或听神经细胞的形态结构，可见畸形前庭的球囊、椭圆囊的囊性结构；（3）进行共同腔畸形人工耳蜗植入手术时，应在耳蜗内镜的监视下，将电极摆放到准确位置，尽可能贴近共同腔的前壁，不应损伤前庭器官。

The head is slowly turned 90° toward the side where nystagmus is induced less intensely. Then the head is rotated 180° rapidly toward the opposite side. This article reports three cases of the ageotropic form of HC-BPPV that were cured by rapid head rotation. The three cases demonstrated that rapid head rotation was an effective maneuver to treat cupulolithiasis on the utricle side. It is recommended that rapid head rotation can be used for therapeutic diagnosis: If nystagmus subsides immediately after this maneuver, the diagnosis is cupulolithias is on utricle side. If nystagmus changes into the geotropic form, the diagnosis is cupulolithiasis on canal side or canalolithiasis in the anterior arm of horizontal semicircular canal. A repositioning maneuver for geotropic form can then be applied to treat these patients.

逆地眼振型水平半规管良性阵发位置性眩晕的3种耳石可能位置如下：水平半规管前臂的管耳石、管侧的顶帽沉石(canal side cupulo-lithias1s)与囊侧的顶帽沉石，本文报告3例以快速转头治疗逆地眼振型水平半规管良性阵发位置性眩晕成功的病例，显示快速转头法对囊侧的顶帽沉石具迅速有效的治疗效果，对於逆地眼振型水平半规管良性阵发位置性眩晕的治疗，作者建议先以快速转头作治疗性诊断，若病人马上复原，诊断为囊侧的顶帽沉石；若眼振转为向地型，则诊断为水平半规管前臂的管耳石或管侧的顶帽沉石，进一步再以向地型的耳石复位法治疗病人。

We have identified a chick homolog gene, cAxin2, which is expressed in the otic cup beginning at stage HH14+ and exhibits a dynamic expression pattern during formation and further differentiation of the otic v.

我们发现了一个鸡的等位基因cAxin2，于HH-14+期，它初始表达在发育内耳的耳杯中，并在内耳的形成及进一步耳囊的分化过程中显示了一个动态的表达方式。

The contents of other metal elements Na, Mg, K, Al, Mn and Pb in lagenal otoliths were not significantly different from those in utricular and saccular otoliths.

瓶状囊耳石中其它金属元素Na、Mg、K、Al、Mn、Pb的含量与球囊和椭圆囊耳石相比无显著性差异，但Zn、Ba、Cu的含量低于球囊耳石。

The contents of other metal elements Na, Mg, K, Al, Mn and Pb in lagenal otoliths were not significantly different from those in utricular and saccular otoliths.

瓶状囊耳石中其它金属元素Na、Mg、K、Al、Mn、Pb的含量与球囊和椭圆囊耳石相比无显著性差异，但Zn、Ba、Cu的含量略低于球囊耳石。

The content of Fe in lagenal otoliths was not significantly different from that in utricular otoliths and was even lower than that in saccular otoliths. The content of Co in lagenal otoliths was lower than that in saccular otoliths and higher than that in utricular otoliths. The content of Ni in lagenal otoliths was not significantly different from that in saccular otoliths and was higher than that in utricular otoliths.

瓶状囊耳石中Fe的含量与椭圆囊耳石相比无显著性差异且低于球囊耳石；瓶状囊耳石中Co的含量低于球囊耳石，但高于椭圆囊耳石；瓶状囊耳石中Ni的含量与球囊相比无显著性差异，但高于椭圆囊耳石。

The content of Fe in lagenal otoliths was not significantly different from that in utricular otoliths and was even slightly lower than that in saccular otoliths. The content of Co in lagenal otoliths was slightly lower than that in saccular otoliths and slightly higher than that in utricular otoliths. The content of Ni in lagenal otoliths was not significantly different from that in saccular otoliths and was slightly higher than that in utricular otoliths.

瓶状囊耳石中Fe的含量与椭圆囊耳石相比无显著性差异且略低于球囊耳石；瓶状囊耳石中Co的含量略低于球囊耳石，但略高于椭圆囊耳石；瓶状囊耳石中Ni的含量与球囊相比无显著性差异，但略高于椭圆囊耳石。

The contents of metal elements Zn, Ba and Cu in lagenal otoliths were lower than those in saccular otoliths. Conclusion The contents of magnetic elements in lagenal otoliths of homing pigeons are not much higher than those in utricular and saccular otoliths, which does not support the hypothesis that birds depend on high contents of Fe and Zn in lagenal otoliths for sensation of geomagnetic information.

结果表明成年信鸽瓶状囊耳石中磁性元素的含量极低而且不比内耳球囊和椭圆囊耳石更丰富，从而不支持信鸽因其瓶状囊耳石中含有较高的Fe、Zn等元素而能够感受地球磁场这一假说。
