无脊髓的

The superficial laminae of the spinal dorsal horn, especially lamina II which is composed mainly of small interneurons, receive primary afferent C fibers which transmit peripheral noxious information, and descending projection fibers from central endogenous antinociceptive system.

脊髓背角浅层，尤其是Ⅱ层是接受无髓和薄髓初级传入纤维传递的外周伤害性信息及来自中枢内源性痛抑制系统投射纤维传递的痛抑制信息的主要部位，胶状质主要由局部环路神经元构成。

The EAE rats were induced by injecting subcutaneously an emulsion of GPSCH and CFA. In addition, each rat received an intracutaneous injection of pertussis. Albumin in serum and CSF samples was examined on the days of 4,6,8,10,12,14,16,18 and 20 p.i.. The integrity of BBB was assessed by caculating CSF to serum albumin quotient. At the same time the brains, spinal cords, thymus and inguinal lymph nodes were removed for paraffin sections cutting. These sections were used for HE staining and ICAM-1 semiquantitative immunohistochemical staining. The results showed as follows:1. None of EAE rats on days 4,6 and 8 p.i. showed clinical signs whichbecame apparent on day 10 p.i.(2.33±0.76; n=6). On days 12 and 14 p.i.

检测p.i。第4天、6天、8天、10天、12天、14天、16天、18天、20天血清和CSF中ALB含量，其CSF／S ALB比值作为评价BBB损害的指标；同时段取动物脑、脊髓、胸腺和腹股沟淋巴结制成石蜡切片行HE染色和ICAM-1半定量免疫组化分析，结果显示如下： 1、EAE大鼠p.i.4-8天无任何临床表现；p.i.10天症状开始明显，症状评分为2.33±0.76(n=6)；p.i.12-14天为发病高峰期，症状评分为3.75±0.54(n=12)，病情由最初的活动减少，体重减轻逐渐发展为肢体无力、瘫痪，共济失调，甚至濒死状态；p.i.16天大部分动物症状开始缓解，评分为2.08±0.66(n=6)；p.i.20天疾病症状完全消失。

The authors conducted a study to evaluate the clinical characteristics and surgical outcomes in patients with spinal schwannomas and without neurofibromatosis.

作者对存在脊髓神经鞘瘤、但无神经纤维瘤的患者进行研究，从而评估这此类患者的临床特点及手术治疗结果。

Objective: Porcine enteric virus is a pathogen, which causing porcine enterovirus infection, such as porcine encephalomyelitis, reproductive failure, pneumonia, diarrhea, cardiopericarditis, myocarditis, dermal lesion, and so on . It is an important infection disease that can damage the pig-raising industries. In this study, porcine enterovirus was isolated and identificated in pocine kidney primary cell.

猪肠道病毒感染是由猪肠道病毒(Porcine enterovirus，PEV)所引起，有多种不同的临床表现，如猪脑脊髓灰质炎、生殖障碍、肺炎、下痢、心包炎和心肌炎、皮肤损伤及无症状等，是一种危害养猪业的重要传染病。

Persistent bilateral leg pain with no history of back pain also suggests inal tumor. Myelography with contrast media or CT scan with metrizamide is e ential to detect intradural and intramedullary tumors.

持续性两侧小腿疼痛而无背痛病史，也提示为脊柱肿瘤，用造影剂作脊髓X线造影或用甲泛影酰胺作CT扫描探查硬膜内或脊内肿瘤是来可少的。

Of the 26 lesions with pontine and bulbar involvement, three had no association with other lesions (Fig 2). Twelve were associated with tegmental and superior cerebellar peduncular extension, and six showed corticospinal tract involvement in continuity with an MDJ lesion. In one patient with additional telencephalic lesions, the right side of the pons was hyperintense on long TR/TE images that did not cross the midline, suggestive of an arterial lesion (Fig 3). In two patients with pontine tegmental lesions, there was an associated middle cerebellar peduncle and deep cerebellar white matter involvement (Fig 4). Two others had associated cervical lesions.

在26处脑桥延髓区病灶中，3处病灶仅限于脑桥延髓区，其它部位无病灶（图2）；12处病灶还同时伴有背盖部和小脑上脚/结合臂处病灶；6处病灶为与中脑-间脑接合处病灶相连的皮质脊髓束受累；还有1例患者除端脑见病灶外，右侧脑桥于T2像也见高信号病灶，但未超越正中线，提示可能系动脉病变所致（图3）；2例脑桥背盖部病灶的患者同时伴有小脑中脚/小脑脑桥脚和小脑深部白质受累（图4）；还有2处脑桥延髓区病灶还同时伴有颈髓病灶。

Results: No differences were observed in the incidences of postdural puncture headacheafter spinal anesthesia with or without pillow support. There were significantly less neck stiffness and significantly improved patients satisfaction in the study group.

研究结果：实验组及控制组在脊髓麻醉后PDPH发生率，在统计上并无显著差异，但在肩颈酸痛程度和麻醉病患满意度方面，统计结果：为实验组肩颈酸痛程度(1.57分)小於控制组(3.23分)；而麻醉病患满意度调查结果为实验组的8.07分，高於控制组的满意度调查结果7.95分，虽两组平均分数差异不大，但统计结果皆为 p＜。05，表示实验组和控制组在统计上有差异。

Distributive characteristics of nitrogen monoxide in spinal cord suggest that adjustment on low sympathetic nerve of rats with cirrhosis is not different from that of the normal.

一氧化氮在脊髓节段的分布特性可能说明肝硬化大鼠在低级交感神经的调控上与正常无差异。

P75 expressed only in the injured sciatic nerve,the ipsilateral spinal ganglion and motor neuronal body of spinal cord, not in the normal peripheral nerve system.

P75在坐骨神经损伤一侧的脊髓前角运动神经元胞体、脊神经节感觉神经元胞体和坐骨神经均有表达，而在未损伤的周围神经系统无表达。

The hen's ASPUT was bilaterally innervated with the sympathetic nerve,although it was the unilateral organ.The ASPUT was also innervated with the intestinal nerve of Remak.There was no sympathetic preganglionic neurons with long axons distributing the ASPUT in Terni's column of the spinal cord.

虽然鸡输卵管仅左侧发育成熟，但接受双侧交感神经的支配；蛋白分泌部还接受肠神经的支配，其性质未定；脊髓Terni柱内无长突型交感节前神经元直接伸达蛋白分泌部。
