Methods: 5 cases of craniocerebral diseases with secondary hydrocephalus were selected to be monitored by LNP-Ⅰ translumbar epidural space intracranial pressure monitor and LY-Ⅱ ventricular pressure monitor grabually. With horizontal position, we recorded with IVP and ISEDP pressure one time per 5 minutes , The datums of LNP-I monitor in the repeated operations were compared with that of IVP, While variations of clinic symptoms, wave forms of pressure, and intermittent ventriculus dranage in the intracranial hypertension were observed.

选择5例颅脑疾病继发脑积水患者，采用LNP-Ⅰ型经腰硬脊膜外腔颅内压监护仪和LY-Ⅱ型脑室内压监护仪进行持续监测，病人取水平侧卧体位，以每隔5分钟记录IVP和ISEDP压力数据一次，期间多次重复操作LNP-Ⅰ型监护仪与IVP进行对照，同时观察临床症状，压力波形及颅高压时间断行脑室引流时二者变化。

Methods OECs were cultured in the olfactory bulb of newborn wistar rat. OECs suspension was infused into the lateral cerebral ventriculus of AE rats, intraperitoneal methyl-vitamine B12 associated with above OECs suspension in combined transpiantion group, and the saline with the same quantity was infused in pseudo-operation group. Afterwards, sport-function grade, histo pathological change were observed.

用新生wistar大鼠嗅球培养OEC，移植组将OECs悬液注入实验性变态反应性脑脊髓炎大鼠的侧脑室；联合移植组在侧脑室注入OECs的基础上，腹腔注入甲基维生素B12；假手术组按以上方法注入等量生理盐水；观察两组大鼠运动功能评分、组织病理学变化。

objective to study mri diagnostic value on multiple sclerosis.methods mri examination data of 31 patients with multiple sclerosis were analysised retrospectively.results total 184 lesions were detectived in 31 patients.most lesions were located on white watter area beside the lateral ventricle,and a few lesions were located on the spinal cord,cerebellum,brain stem and corpus callosum.the shape of lesion can be circle or ellipse.the lesion showed as slightly long t1 and long t2 signal.the acute stage lesions can have enhancement.conclusions ms have characteristic findings on mri image.mri can show the patholoic changes,and provide strong evidence for clinic diagnosis of multiple sclerosis.

摘 要］目的：探讨多发性硬化（muliplle sclerosis，ms）的mri特征表现及其诊断价值。方法：回顾分析31例临床诊断为ms患者的mri检查资料。结果：31例共发现病灶184个，病灶于侧脑室旁白质区、半卵圆中心及皮层下区最多见，其次见于脊髓小脑、脑干及胼胝体，部分可见视神经受累，病灶呈卵圆形或圆形稍长t1、长t2信号，矢状位像见病灶与侧脑室垂直，急性病灶增强扫描有的可呈结节状、环状或斑点状强化。结论：在mri图像上ms有特征性表现，mri能反应ms病理变化，为临床诊断ms提供可靠依据。

The results showed that NOS positive neurons were present in the hippocamp us CA1～CA3） in which NOS strong positive neurons were in CA2; NOS medium positive nucleus in the nuclei nervorum non-cranialium (red nucleus、 su bstantia nigra; NOS positive neurons in the nuclei nervorum cranialium (oculomo tor、 accessory oculomotor nucleus, facial nucleus, abducens nucleus); NOS posit ive nucleus in the pons reticular formation; NOS positive nucleus in the raphe n ucleus and in the plexus chorioideus ventriculi quartic and plexus chorioideus v entriculi tertii.

结果显示：海马(CA1～CA3区)NOS为阳性、其中CA2 为强阳性++）；非脑神经核(红核、黑质为中等阳性；而脑神经核(动眼神经核、动眼神经副核、面神经核、展神经核)NOS为阳性；脑桥网状结构为阳性；缝核群为阳性；第三脑室和第四脑室脉络丛为阳性。

Intraventricular meningiomas are believed to arise from the arachnoidal cap cells trapped within the choroid plexus, the tela choroidea, or the velum interpositum.

脑室内脑膜瘤据信是起源于脉络丛、脉络组织、中间帆内的蛛网膜帽状细胞，相应的，侧脑室三角区是最常见的发病部位。

Other major features include: partial or complete callosal agenesis, cortical malformations periventricular and subcortical heterotopias, cysts around the 3rd ventricle and/or choroid plexuses, papillomas of choroid plexuses, hypoplastic cerebellum, retrobulbar cysts, microophthalmia and colobomas.

其他主要表现包括：部分或完全的胼胝体发育不良，皮质畸形，脑室周，皮质下异位，环绕三脑室和脉络丛囊肿，脉络丛乳头状瘤，小脑发育不良，眼球后囊肿

The colon temperatures were measured by a thermistor and the cytosolic free calcium concentration ([Ca2+]i) in dissociated brain cells was measured by Fura 2-AM. The results demonstrated that the pyretic action of egtazic acid (0.6 μmol, icv) was markedly inhibited by DEX (5 mg/kg,iv), but DEX (60-120 μmol/L) did′t affect [Ca2+]i in dissociated hypothalamus cells. Actinomycin D, which interferes with gene transcription (3 nmol, icv), completely abolished the antipyretic action of DEX on egtazic acid-induced fever.

结果发现：脑室灌注乙二醇双(2-氨基乙醚)四乙酸(0.6 nmol)引起家兔结肠温度明显升高，静脉注射地塞米松(5 mg/kg)显著抑制家兔乙二醇双(2-氨基乙醚)四乙酸性发热，地塞米松(60-120 μmol/L)并不影响下丘脑细胞内[Ca2+]i，而事先脑室灌注抑制基因转录的放线菌素D(3 nmol)则完全取消了地塞米松对乙二醇双(2-氨基乙醚)四乙酸性发热的解热作用。

Results: ADC in MS group was increased in all regions of NAWM compared to controls(P＜0.05),significantly higher in the body of corpus callosum, internal capsule, periventricular WM, frontal WM, parietal WM and occipital WM(P＜0.01). FA value in MS group was decreased in the body of corpus callosum, internal capsule, periventricular WM, frontal WM, parietal WM and occipital WM(P＜0.05), the genu and splenium of CC,middle cerebellar peduncle showed an insignificant trend of lower FA.

结果：MS组的正常表现脑白质的ADC值均高于对照组(P＜0.05)，以胼胝体体部、内囊、侧脑室旁及额、顶、枕叶脑白质更为显著(P＜0.01)；MS组的FA值与对照组比较，胼胝体体部、顶、额、枕叶白质及内囊、侧脑室旁发现明显降低(P＜0.05)，以后4个部位更为显著(P＜0.01)，而胼胝体膝部、压部和小脑结合臂有降低趋势，但无统计学意义。
