神经萎缩

Furthermore, abnormal morphology, shrinkage and reduced density of dendritic spines and defects in LTP were observed in brains of the patients suffering from mental retardation and neurodegenerative diseases; many mutant genes found from these patients encode component proteins of signal transduction for neuronal plasticity. These studies on synaptic plasticity would certainly promote making the effective prevention and treatment procedures for mental and neurodegenerative diseases.

此外，在精神迟滞性疾病和神经退行性疾病患者脑内记录到异常的LTP，并发现神经元的树突棘数量减少，形态上产生畸变或萎缩，同时发现，产生突变的基因大多编码调节突触可塑性的信号通路蛋白，故突触可塑性研究也将促进精神和神经疾病的预防和治疗。

BACKGROUND: After amyotrophic lateral sclerosis, motor neurons have changes in neural degeneration, but the precise mechanism is not clear.

摘要背景：肌萎缩侧索硬化后运动神经元存在神经变性改变，但其确切机制不明，内源性神经干细胞被认为是未来能有效解决此病的治疗方法之一。

AIM: To explore the diagnostic value of computed tomography in optic atrophy.

目的：探讨CT对视神经萎缩的诊断价值。

NKCCl(superscript -/-) mice were deaf and demonstrated difficulties in maintaining their balance. NKCC1 mice exhibited a marked atrophy of the stria vascularis, contraction of the endolymphatic compartments and collapse. CONCLUSION: NKCCl channel plays a critical role in potassium homeostasis of endolymph in the inner car.

光镜下NKCCl野生型小鼠和NKCCl杂合子小鼠的耳蜗解剖结构无明显异常；NKCCl突变纯合子小鼠的耳蜗出现前庭膜塌陷、内淋巴腔缩小而致中阶完全消失，并有血管纹萎缩、Corti器缺失、螺旋神经节萎缩；且球囊和椭圆囊膜迷路失去正常结构并出现塌陷等病理改变。

Alzheimer disease: A primary degenerative cerebral disease of unknown etiology with characteristic neuropathologcal and neurochemical features, including cortical atrophy with neurofibrillary tangles and neuritic argentophilic plaques, and a marked reduction on the enzyme choline acetyltransferase, in acetylcholine itself, and in other neurotransmitters and neuromodulators.

阿尔茨海默病：一种病因未明的原发退行性大脑疾病，具有特征性的神经病理和神经生化改变，包括伴有神经原纤维缠结和神经炎性嗜银斑的皮层萎缩，胆碱乙酰转移酶、乙酰胆碱本身、以及其它神经递质和神经调质的明显减少。

Neurotomy law refers to the leg turnips removed to connect the gastrocnemius nerve, so that the principle is the same as shrinking the muscles, so thin legs, but once the nerve repair broken unlikely to form a permanent injury.

神经切断法指的是切除连接萝卜腿腓肠肌的神经，原理一样是让肌肉日渐萎缩，让小腿变细，不过一旦神经断了恐难修复，形成永久性伤害。

RESULTS: The mild traction group showed angulus anterior individual neuron slightly engorged, neuron and nerve fiber morphous was normal essentially; individual substantia alba demyelinates in fragmentis; medullary sheath and auxiliary fibers of nerve root were hydropsia slightly without conspicuous myelinolysis. The moderate traction group demonstrated myelinolysis change in the spinal cord, and neurofibras lined up chaos, auxiliary fibers disaggregated, neuron dropsy, tigroid body disappeared with karyopycnosis and anachromasis in neurons; nerve root showed myelinolysis. The severe traction group displayed a great demyelination region; anterior motor neurons with karyopycnosis and anachromasis; myelinated nerve fiber of nerve root shrinked, decreased in number, with severe demyelination changes.

结果：轻度牵拉组牵拉侧前角个别神经元稍肿胀，神经元及神经纤维形态基本上正常，个别白质小片状脱髓鞘样改变，神经根髓鞘和轴索轻度水肿，脱髓鞘不明显；中度牵拉组白质有脱髓鞘改变，神经纤维排列紊乱，轴索崩解、断裂；灰质神经元水肿明显加重，前角运动神经原细胞尼氏体消失，核固缩、深染，神经根髓鞘和轴索水肿，局部轻度脱髓鞘改变；重度牵拉组牵拉侧白质为不规则的大片脱髓鞘区，前角运动神经元胞体固缩、变形、核深染，神经根有髓神经纤维萎缩、数目减少，重度脱髓鞘改变。

AbstractWe present the early diagnosis method of agerelated macular degeneration , and characterize various pathological changes arising in the development of AMD, such as drusen, chorioretinal mapshrinking, retinal pigment epithelial atrophy, choroidal neovascularization, retinal pigment epithelium and neural epithelial detachment, and so on. We analyze its images by using optical coherence tomography.

本文给出了一种老年性黄斑变性（agerelated macular degeneration， ARMD ）的早期诊断方法，在 ARMD 的发展过程中出现的各种病理改变如玻璃膜疣、脉络膜视网膜地图状萎缩、视网膜色素上皮萎缩、脉络膜新生血管、视网膜色素上皮/神经上皮脱离等，用光学相干断层成像技术（optical coherence tomography，OCT）对其进行图像分析。

The results indicated that:(1) 4 d or 6 d after denervation, increase of endocyto--sis and proliferation of satellite cells in denervated muscle were induced.(2) Actino--mycin D inhibited activation of satellite cells and endocytosis in normal muscle.

结果表明：(1)去神经4d或6d的肌肉可引起胞纳的增加和卫星细胞的增殖；(2)放线菌素D抑制正常肌肉的卫星细胞激活和胞纳作用；(3)在去神经的肌肉中，放线菌素D抑制了卫星细胞增殖的同时还抑制了胞纳的增加，但不能阻止去神经肌肉的萎缩。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
