神经纤维

AbstractIt had been shown in many studies that glaucomatous retinal nerve fiber layer damage could be observed and measured even in the absence of perimetric abnormalities.

研究表明青光眼的视网膜神经纤维层(retinal nerve fiber layer，RNFL)损害早于视野改变。

Each nerve tract was surrounded by the perineural cell with long and thin processus.

雪旺氏细胞与两种神经纤维的形成与结构密切相关。

AIM: To investigate the distribution characters of nerve fibers in rat molar and periodontium.

目的：观察大鼠磨牙及牙周组织神经纤维分布特点。

To measure the thickness of peripapillary retinal nerve fiber layer in normal Chinese subjects with optical coherence tomography and to identify the factors that might affect RNFL thickness.

目的 应用相干光断层扫描仪测量中国正常人视网膜神经纤维层厚度并探讨年龄、屈光度、性别及视盘面积对平均RNFL厚度的影响。

Qualitative and quantitative methods were applied to evaluate the relations among hemorrhage of optic disc, defect of retinal nerve fiber layer, and peripapillary atrophy by using stereo ocular fundus photography and computer analyzer systems.

患者行每月1次眼底照相，眼底立体照相和计算机图像分析系统定性及定量评估视盘出血与神经纤维层缺损及萎缩弧的关系。

PURPOSE: To evaluate the reproducibility of peripapillary retinal nerve fiber layer thickness and ganglion cell complex measurements made with the RTVue-100 Fourier-domain optical coherence tomography device (Optovue, Inc., Fremont, CA) and to determine the influence of 4 factors: pupil dilation, subject age, experience in imaging examinations, and glaucoma severity.

目的：评估RTVue-100傅里叶域光学相干断层扫描仪（Optovue公司，加州弗里蒙特）测量视盘周围视网膜神经纤维层厚度和神经节细胞复合体的重复性，并确定4个影响因素：瞳孔散大、受试者年龄、进行过影像检查和青光眼严重程度。

Objective To study the wave form of the photopic negative response in electroretiongram, and the relationship between PhNR and retina nerve fibre layer thickness, visual field mean defect, and cup/disc ratio. Investigate the function of PhNR in diagnosis of traumatic ocular nerve atrophy and evaluation of ocular nerve ganglion cells.

目的 研究外伤性视神经萎缩的视网膜电图各成分及其明视负向反应的变化特点，并进行PhNR与视网膜神经纤维层厚度、视野平均缺损值，以及杯盘比的相关性研究，探索在外伤性视神经萎缩中PhNR的变化规律。

There were abundant networks of NPY-Ir nerve fibers in the pial mater. It is expected that NPY released from these nerve fibers might be one source of Y〓-R ligands in SMCs, especially in the arteries under second branchs and in the arterioles.

在软脑膜中有密集的含NPY-Ir神经纤维网，所分泌的NPY可能是脑动脉（特别是第二级分支以下的小动脉和微动脉）平滑肌细胞中〓受体的配体来源之一。

Results The neurological defects score was singificiant lower in D group (41.50±8.18) than that in group A(82.20±8.08), B(63.60±6.22) and C (61.00±6.58)(all P.01). Compared with groups A, C, group D showed that the cellular nucleus was shrinkaged slightly, the gap of cells was nomal roughly and the degree of rarefaction in neurofibra net was not serious under the light microscope. Under the electron microscope, the neuron was degenerated, the cellular membrane was integrated and the plastosome was swelled lightly in the group D. The physiological demage were slighter in D group.

结果 D组神经功能缺损评分(41.50±8.18)明显低于A组(82.20±8.08)、B组(63.60±6.22)和C组(61.00±6.58)（均P.01）；光镜下D组神经细胞核轻度皱缩，细胞周围间隙大致正常，神经纤维网疏程度不严重；电镜下D组神经元轻度变性，细胞核无皱缩，核膜完整，线粒体轻度肿胀；脑组织病理损害程度较B组和C组明显减轻。

RESULTS: VIP widespread expression existed on photoreceptor-outer, inner nuclear layer, inner plexiform layer of retinal and choroids; weak expression existed on ganglion cell layer and nerve fiber layer.

结果： VIP的表达主要位于视网膜光感受器外节、内核层、内丛状层和脉络膜，在神经节细胞层和神经纤维层有较弱表达。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
