Methods Strial capillary endothelial cells in guinea pig cochlea was dissociated and cuhureed to establish a model for its permeability in vitro.,The animals were divided into TNF-α,TNF-α+L-arginine,TNF-α+NG-minomethyl-L-arginine and control groups.

体外分离培养豚鼠耳蜗血管纹微血管内皮细胞并建立内皮细胞通透性体外模型，观察TNF-α、TNF-α连同L-精氨酸(L-arginine，L-Arg)或L-单甲基精氨酸(NG-monomethyl-L-arginine，L-NMMA)对内皮细胞通透性的影响。

Being as a NO donator,L-Arg siguitlcanfly enhanced the ability of TNF-α which increasing permeability of strial capillary cndothelial cells;permeation rate to Evans blue beightened significantly(P＜0.01),which obviously rose up when the concentration of Evans blue added.L-NMMA,NO inhibitor,was able to weaken the ability of TNF-α which increasing permeability of strial capillary endothelial cells:permeation rate to Evans blue decreased siguificantly (P＜0.01),which obviously fell down when the concentration of L-NMMA added.

一氧化氮(nitric oxide，NO)供体L-Arg能增加TNF-α作用下耳蜗血管纹微血管内皮细胞的通透性，使伊文思蓝的通透率升高，差异具有统计学意义(P值均＜0.01)，且随着L-Arg浓度的增加内皮细胞对伊文思蓝的通透率也明显增加。

Objective To investigate the change of the ribbon synapses in inner hair cells by using gentamicin.

目的探讨庆大霉素对耳蜗内毛细胞带状突触数量的影响及其意义。

But inner hair cell and tectorial membrane were normal.4. The quantities of nNOS and iNOS increased obviously in the cochlea of HIE rats.

1。缺氧缺血时，nNOS和iNOS在新生大鼠耳蜗的内、外毛细胞，血管纹，螺旋神经节等细胞的分布增多，但两者的活性变化不同，分别在缺氧缺血的早期和晚期时活性最强。

Methods Two-2D finite-element models were built based on the electron microscopic images of the organ of Corti from the guinea pig with two models of coupled and non-coupled between the tectorial membrane and stereocilia.

以豚鼠耳蜗底回Corti器的电镜图像为原型，建立盖膜与内毛细胞最长静纤毛接触和不接触的两种二维计算模型各一个，并作力学分析比较。

Results Smad4 genes were expressed throughout the postnatal cochlea of three mouse genotypes at a high level. The expression concentrated in the vascular stria, spiral ligament, basal membrane, tectorial membrane, hair cells, supporting cells and spiral ganglion cells.

结果 Smad4在三种基因型小鼠耳蜗均有广泛表达，表达部位主要集中于血管纹、螺旋韧带、基底膜、盖膜、毛细胞、支持细胞、螺旋神经节细胞等处，其中血管纹和基底膜表达最为明显。

ABSTRACT This paper researches a new type of mechanical transmission mechanism, the toroidal drive.

本文研究了一种新型的传动机构--超环面行星蜗杆传动。

Thirdly, Friction, wear and lubrication for toroidal drive are discussed systematically and completely.

第三，对超环面行星蜗杆传动的摩擦学问题进行了深入系统的研究。

Firstly, the engaging theories for toroidal drive are discussed systematically and completely.

第一，对超环面行星蜗杆传动的啮合理论进行了深入系统的研究。

Meanwhile the meshing theory analyzing of toroidal drive for different rollers are also studied.

对不同滚动体情况下超环面行星蜗杆传动的啮合理论进行了探讨。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
