1.
Objective:To study the characteristic manifestations of tumefactive demyelinating lesion on enhanced MRI and also to discuss the surgical methods in accordance with specific circumstances.
目的:研究瘤样脱髓鞘病(tumefactive demyelinating lesion,TDL)在增强MRI上的特征性表现,探讨特定情况下该病的手术。
4) Tumor-like demyelination
肿瘤样脱髓鞘
6) demyelination
[英][di:,maiələ'neiʃən] [美][di,maɪələ'neʃən]
脱髓鞘
1.
Results Various degrees of inflammation and demyelination of brains and spinal cords were found in t.
结果病理检查发现EAE模型组大鼠脑、脊髓有不同程度的炎症反应和脱髓鞘改变;均有视神经病变,光镜主要表现为炎症反应和脱髓鞘,视神经髓鞘脱失重于炎症反应;电镜主要表现为髓鞘稀疏,少突胶质细胞数量减少、胞核固缩,其周围包裹的髓鞘板层松解,轴突髓鞘分离。
2.
Objective: To explore mechanism of demyelination and remyelination in cuprizone-induced acutely demyelinated animal model.
目的:利用cuprizone制备髓鞘可再生的急性脱髓鞘动物模型,探讨脱髓鞘疾病髓鞘再生机制。
3.
In these mice, status of demyelination and remyelination were studied by using myelin staining, and the changes of oligodendrocyte progenitors (OLPs) were demonstrated by immunohistochemistrical staining following in situ hybridization.
结果表明,给予cuprizone6周后,动物胼胝体严重脱髓鞘,少突胶质前体细胞在髓鞘脱失区域集聚,且增殖活跃;恢复正常饲料饲养4周后,髓鞘基本恢复正常形态。
补充资料：脱髓鞘疾病
| 脱髓鞘疾病 demyelinating disease 神经纤维的髓鞘脱失而神经细胞相对甚少受累的一类疾病。病因不同，临床表现各异，但具有共同的病理特征。这类疾病分为两组，即髓鞘形成障碍型和髓鞘破坏型。髓鞘形成障碍型脱髓鞘疾病是遗传代谢缺陷引起的髓鞘形成障碍，主要包括髓鞘磷脂代谢异常引起的脑白质营养不良，如异染性白质脑病、脑白质海绵样变性、肾上腺白质营养不良等。髓鞘破坏型脱髓鞘疾病是后天获得的脱髓鞘疾病。病因为：①免疫介导，如多发性硬化、急性感染性多神经根神经炎。②病毒感染，如进行性多灶性白质脑炎、亚急性硬化性全脑炎。③营养障碍，如脑桥中央型髓鞘崩解症。④缺氧，如迟发性缺氧后脱髓鞘脑病、进行性皮质下缺血性脑病。一般临床上诊断脱髓鞘疾病时多指免疫介导的脱髓鞘疾病，包括多发性硬化、急性感染性多神经根神经炎等。 |
