神经纤维

Structure in the visual pathway where part of the fibers from each nerve decussate to from the optic tracts.

视交叉：是视觉途径中的一个构造，有些是神经纤维在此会交叉。

A technology of electrolytic lesion was used to destroy the projections of cerebellar FN neurons to hypothalamus in decussation of superior cerebellar peduncle.

电毁损小脑上脚交叉中顶核投射至下丘脑的神经纤维，然后再用生物素化葡聚糖胺顺行追踪观察小脑顶核-下丘脑之间神经元投射。

Results: Subsequent to an injection of BDA into unilateral FN, FN-hypothalamic projections passed through the superior cerebellar peduncle, crossed in its decussation and then entered the hypothalamus.

结果：小脑顶核注射BDA后第8 d，在用3，3-二氨基联苯胺和Nissl染色的脑切片上，观察到顶核神经元发出的神经纤维在小脑上脚中行走，并经小脑上脚交叉后主要到达对侧下丘脑外侧区。

But most relevant to us for the purposes of this hearing is that mercury has clearly been shown to causes a denudation of the neurofibrils resulting in direct damage to the neuronal cells.

对我而言，这个听证会最相关的的主题就是清楚地显示出汞造成神经纤维变性导致神经细胞直接的伤害。

The CPT values in the affected leg in patient group were significant higher than those in control group at all frequencies. The CPT values in contralateral leg in patient group were significant higher than those in control group at 5Hz whereas there were no significant differences at 250Hz and 2000Hz. The CPT values in affected leg in patient group were significant higher than those in contralateral leg at 250Hz and 2000Hz whereas there were no significant differences at 5Hz. All the CPT values showed the same linear decrease from the dermatome of the compressed root to the dermatomes of the contralateral neighbor dematom.

在用CPT监测8例腰骶单神经根病组患侧和健侧及与正常对照组的不同直径感觉神经纤维功能的研究中发现压迫皮节和其临近皮节的所有频率CPT值无任何显著性差别；患者压迫侧的2000Hz及250HzCPT值及压迫侧和对侧的5HzCPT值与正常对照组都有显著性差别；患者组5HzCPT值患侧和对侧无差别，其他两组均有显著性差别；不管有无显著性差别，神经根病患者组各皮节三频率CPT值均按照压迫皮节，临近皮节，压迫对侧皮节，压迫对侧临近皮节的顺序减小，说明在腰骶单神经根病中Aβ纤维及Aδ纤维及无髓C纤维均受累。

There were 36 males and 40 females,with the average age of 47.7 years.36 patients presented with sciatica and perineal numbness,11 patients had painless mass and the other 20 were identified due to other causes.Among 67 benign neurogenic tumors,54 were originated from S1-S3 nerves,3 from S4-S5 nerves and 11 from the presacral space without caudal involvement.Giant cell tumor was found in 60 patients,which included 24 males and 36 females,with an average age of 32 years.Upper sacrum（S1-S2） was involved firstly.There were 56 patients（average,37.7 years） diagnosed as other primary benign bone tumors,which included 24 cases of teratomas,epidermoid cyst or dermoid cyst.Other malignant tumors,including chondrosarcoma （17）,Ewing′s sarcoma/PNET（14）,multiple myeloma（12）,lymphoma（6） and osteosarcoma（6） were found in 64 patients.

其中脊索瘤95例，男62例，女33例，平均年龄55.7岁，骶尾区疼痛是主要症状（82例），半数以上患者伴有坐骨神经痛，肿瘤多先累及低位骶骨（S3~S5）；神经源性肿瘤76例，男36例，女40例，平均年龄47.7岁，神经纤维瘤43例，神经鞘瘤24例，恶性神经鞘瘤9例，主诉多为坐骨神经痛、会阴部麻木（36例）和无痛性包块（11例），20例患者为查体或其他原因检查时发现，67例骶骨良性神经源性肿瘤起源于S3以上神经者54例，起源于S3以下神经者3例，发生于骶前未累及骶管者10例；骨巨细胞瘤60例，男24例，女36例，平均年龄32岁，腰骶尾部不适（37例）、坐骨神经痛（21例）是主要的临床表现，肿瘤多先累及上位骶骨（S1~S2）；骶骨其他原发良性肿瘤及瘤样病变56例，包括畸胎瘤、皮样囊肿、表皮样囊肿共24例；其他原发恶性肿瘤64例，包括软骨肉瘤17例，尤文肉瘤14例，多发性骨髓瘤12例，成骨肉瘤6例等。

Results:(1)Different dioptre caused different pathogenic rate;(2)The pathogenic rate of high glaucoma and myopia is higher than that of low myopia.Among them,34 cases were＞－6D(79.07%),9 cases were ＜-5.75D(20.93%).(3)Increased tension of eyeball was the main character;(4)The optic disc was not regular;(5)Early glaucomatous structural change had high sensitivity.

结果：(1)43例患者不同的屈光度发病率不同；(2)高度近视青光眼发病率高于低度者，本组病例＞－6D 34例，占79.07%；＜－5.75D 9 例，占20.93%；(3)眼压升高是近视合并青光眼的主要特征；(4)视盘形态不规则较显著；(5)视网膜神经纤维层检查发现早期青光眼结构改变的敏感性很高。

Furthermore,GDNF was found in the sensory nerve fibers of DRG.

GDNF在背根节感觉神经元和神经纤维中有一定量的分布。

Hybrid schwannoma/perineuriomas have no evident association with neurofibromatosis and rarely recur. The pathogenetic basis of the dual pattern of differentiation in these lesions remains poorly understood at this time.

混合性神经鞘瘤/神经束膜瘤与神经纤维瘤病无明显关系，且罕有复发，其瘤组织双重分化的发生机制目前仍不清楚。

METHODS: Nerve fiber analyzer Ⅲ-GDxVCC (produced by Laser Diagnostic Technologies, San Diego, CA,USA) was applied to measure RNFL thickness of 85 volunteers with myopia (166 eyes) and 23 volunteers with emmetropia (42 eyes).

采用视神经分析仪-GDxVCC（美国激光技术诊断公司生产）测量正常人23例42眼和近视眼患者85例166眼视网膜神经纤维层厚度，近视眼患者按等效球镜屈光度分为低、中、高、超高度近视四组，将所得结果用SPSS11.5统计软件包进行统计分析。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
