神经纤维

By using this method, small and soft brain even with thin wall and large ventricle could be sliced coronally, sagittally, horizonally or obliquely.

由于动物个体间的差异，脑内核团和神经纤维与脑外表形状的相对位置存在者差异，切片过程中需要随时调节角度。

These results indicated that ES cells with lower level of spontaneous differentiation could go into neural differentiation, while those with higher level of spontaneous differentiation would dedifferentiate and die during neural differentiation.

在进入神经分化的细胞中，其分化的进程与预培养24h组相似，但向外迁移的细胞减少，缺乏广泛的神经纤维联系。

The structure of axon was completed, and the arrangement of regenerated nerve fibers with rotund or elliptoid shapes was closed.

电镜超微结构观察可见再生的神经纤维较粗大，排列紧密，呈均匀一致圆型或椭圆型，髓鞘较厚，轴突结构完整。

Objective To investigate the effects of sterigmatocystin on the ependymal cells,neurons and endothelial cells of blood vessel of the lateral recess of the fourth ventricle in BALB/c mice in vivo after single oral administration.

目的观察杂色曲霉素对外侧隐窝处室管膜细胞、神经元、神经纤维和血管内皮细胞的影响。

Methods BALB/c mice were treated intragastrically by gavage with ST 3000?μm/kg.The mice were killed 1 hour,2 hours,4 hours,8 hours,16 hours after oral administration respectively for observing ependymal cells,neurons and endothelial cells of blood vessel of the lateral recess with transmission electron microscopy.

BALB/c小鼠，ST单次灌胃，分别于灌胃后1、2、4、8、16 h处死动物，用透射电镜观察外侧隐窝室管膜细胞、神经元、神经纤维和血管内皮细胞的结构变化。

Methods Nuclear β-catenin expression was detected by immunohistochemistry in 77 lesions with desmoid-type fibromatosis and 171 other spindle cell lesions, including superficial fibrmoatosis (n=18), nodular fasciitis (n=36), keloid (n=16), scar (n=10), granulation tissue (n=9), synovial sarcoma (n=38), neufibroma (n=13), solitary fibrous tumor (n=12), gastrointestinal stromal tumor (n=10), low-grade myxofibrosarcoma (n=3), low-grade fibromyxoid sarcoma (n=3), and smooth muscle tumor (n=10). In addition, the immunohistochemical expressions of ER-α, ER-β and Ki-67 were examined in all of the lesions with desmoid-type fibromatosis. The nuclear immunohistochemical staining for nuclear βcatenin and ER-β was graded as high level (≥25% of cells), low level (5%-25%) or none.

采用免疫组织化学染色法检测77例韧带样型纤维瘤病和171例其它良、恶性梭形细胞病变（包括结节性筋膜炎36例、浅部纤维瘤病11例、瘢痕疙瘩16例、增生性瘢痕10例、肉芽组织9例、滑膜肉瘤38例、神经纤维瘤13例、孤立性纤维性肿瘤12例、胃肠间质肿瘤10例、低度恶性黏液纤维肉瘤3例、低度恶性纤维黏液样肉瘤3例及平滑肌肿瘤10例）组织中β-catenin核阳性的表达，同时检测韧带样型纤维瘤病中ER-α、ER-β和Ki-67的表达。

While symptoms may seem to improve almost immediately after surgery, it takes approximately 6-12 months before new vessels develop sufficiently. Diseases associated with moyamoya include sickle cell anemia, atherosclerosis, prior radiation therapy to the skull base in children, and less commonly neurofibromatosis, tuberous sclerosis, meningitis, retinitis pigmentosa, fibromuscular dysplasia, Down's syndrome and Fanconi's anemia.

手术之后几乎立即可以看到症状的好转，新的血供充分发展起来大概要花6-12月时间。moyamoya相关的疾病包括镰状细胞性贫血、动脉粥样硬化、颅底部放疗，不太常见的有神经纤维瘤病，结节性硬化、脑膜炎、色素性视网膜炎、纤维性肌发育不良、Down氏综合症和Fanconi's 贫血症

The attenuation values at unenhanced and enhanced CT of the tumor were also recorded. Results The 32 cases adrenal neoplasms included 9 cases with aldosterone-producing adenoma, 5 hydrocortisone-producing adenomas, 1non-functional adenoma, 5 cortical hyperplasies,4 pheochromocytomas,2 adenocarcinomas, 3 metastases, 1 fibroneuroma, 1 ganglioneuroma and 1 myelolipomas. Conclusion The characteristics on CT images are associated with the pathological feature in adrenal neoplasms.

结果 醛固酮腺瘤9例，体积较小且密度低，增强后轻度增强；皮质醇腺瘤5例，瘤体较大，边界清，密度略低于正常肾上腺组织；无功腺瘤1例；结节增生5例，为等或稍低密度影，增强后强化较明显；嗜铬细胞瘤4例，体积较大，密度不均，可见多个囊变坏死区；皮质腺癌2例，肿块形态不规则，边缘模糊，密度不均匀，易发生大片坏死及点状钙化；转移瘤3例；神经纤维瘤、神经节瘤及髓性脂肪瘤各1例。

Methods The study was performed concering the neurons and fibers of SP,CGRP and VIP-immunoreactive substance in three predominant superfical ganglial plexus of the guinea pig heart by immunohistochemical ABC method and observed by light microscope.

应用免疫组织化学ABC法，对豚鼠心脏表面3个主要神经节丛的神经元及神经纤维进行了SP、CGRP及VIP免疫组织化学染色及光镜观察。

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。
