老年性聋

According to this theory, we can stay caducity by reducing free radicals to treat presbycusisi.

我们可以推测抗自由基的治疗可以延缓衰老，改善老年性聋。

Part three:Cochlear on Hair Cell Like Cells Regeneration in Presbycusis C57BL/6 Mice after Math1 Gene Inner Ear TransfectionIn order to test the probability of Mathl gene induces hair cell like cells regeneration in cochlea of presbycusis C57BL/6 mice,8 mounths old C57BL/6 mice were used for this study and were microinjected with Ad-MathlorAd-EGFP in the scala tympani by ventral approach.

第三部分老年性聋模型小鼠C57BL/6耳蜗鼓阶外源基因Math1导入后出现毛细胞样细胞现象的观察为了观察老年性聋C57BL/6小鼠(8月龄)耳蜗鼓阶外源基因Math1导入后能否在老年性聋的耳蜗微环境诱导出新生的毛细胞样细胞，为Math1基因治疗老年性聋进行探索性研究。

The result indicates that the decrease of potassium channel function in aged rat cochlear nucleus may be related to presbycusis.

移植的老年大鼠耳蜗核钾离子通道功能的下降可能与老年性聋的发病有关。

So we think that DML can be used to treat presbycusis by clearing free radicals. We will continue our search on free radicals.

因此我们可以推测碟脉灵也具有这一作用，可以通过清除自由基来治疗老年性聋，我们将在这一方面做进一步的研究。

The presence of systemic diseases as hypertension, coronary heart disease and diabetes mellitus is relevant to higher rate of presbycusis.

全身老年性疾病如高血压，冠性病，糖尿病可增加老年性聋的发生率。

The investigation provides epidemiologic evidence for researches on mechanism of presbycusis, especially on susceptibility genes and longevity genes.

社会福利院60岁以上的老人相对集中，听力残疾发生率较高，这是老年性聋发生的一个缩影，应引起全社会对老年人的听力保护和康复的重视；老年听力残疾人中男性比女性多，而未定等级的10例中，女性又较男性多，这又为研究老年性聋发生机理，特别是易感基因或长寿基因的研究提供了流行病学调查的依据。

The major cause of age-related hearing loss is presbycusis.

老年人听力减退主要原因为老年性聋。

In order to test the probability of Math1 gene induces hair cell regeneration in cochlea of presbycusis mice,we prosecuted the study and divided into three parts as following.

本研究拟行C57BL/6小鼠老年性聋动物模型评价；小鼠耳蜗外源基因导入途径及方法的研究；老年性聋C57BL/6小鼠内耳Math1基因导入后毛细胞样细胞的观察。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
