小脑后的

The suboccipital retrosigmoid approach was used on 10 adult head specimens which were fixed and perfused with color silicon, the neurovascular structures and their relationship in cere- bellopontine angles were observed under the operative microscope and endoscope.

选择经10％福尔马林充分固定，血管内灌注混有红、蓝染料的乳胶，不分性别的成人尸头10具，模拟目前临床上最长使用的枕下乙状窦后入路，在手术显微镜和神经内窥镜下，观察小脑桥脑角内的神经血管结构，确认这些神经血管的走行及其之间的解剖关系。

Ray will show the associated skeletal anomalies, such as skull base invagination, scoliosis, kyphosis, cervical ribs, and many other skeletal anomalies. Axial images with CT may demonstrate an obliterated cisterna magna, tonsillar ectopia, and a normal fourth ventricle.

线可以显示出伴随的骨骼异常，如颅底凹陷，脊椎侧弯，脊椎后突，颈肋，以及许多其他的骨骼异常，CT轴位图像可以显示一个闭塞的小脑延髓池，扁桃体异位，以及正常的四脑室。

Comclusion: transpetrous presigmoid retrolabrinth approach was rational approach for surgery on petroclivus and -4- CPA; it抯 important for accomplish the surgery to study and master the anatomy and variance of this approach; there was relative anatomical relationship among those structure on posterior of petrous bone; AAMP was the extracranial mark of inflexion of TS and SS; LAM and PSC were obvious bone marks for operation; we can confirm the abraded range of petrous bone lean upon LAM and/or GSS beside abrading step by step as literature, and it抯 unnecessary and unrational to emphasize to show PSC if the surgical space was enough; preceding sigmoid sinus and high jugular bulb often appeared at right and would bring disadvantage effect; interspace ,between CN V and CNVII or CNVII and CNJXI, were available to reach clivus and manage the mass on the range.

经SS前迷路后入路是处理岩斜坡区、桥小脑角区病变理想的手术入路；研究和熟悉手术入路中的解剖结构及部分变异对指导手术十分必要；岩骨内测面的骨性结构之间有着相对稳定的空间关系；顶乳缝前角是SS和TS转接处在颅外的标志；IAM和PSC等结构可以作为手术中的重要骨性标志；以PSC确定岩骨的磨除范围是较安全和可靠的，但亦可以结合影像检查，以内耳道和乙状窦前缘为基点判定切除范围，如果操作空间足够，过分强调磨出半规管是不适当的；右侧GSS的宽度和深度较对侧大，SS前置和颈静脉球高位较对侧多见，这些都对右侧入路有不利的影响，但仍可以进行手术操作；三叉神经和面神经间隙及面l 神经和舌咽神经间隙方便到达斜坡并处理病变。l

The distributions of Hup A into rat brain tissues following intranasal dosing were compared with those after intravenous and intragastric dosing by tissue homogeneization.

结果大鼠鼻腔给药血浆AUC0→6h为静注的0.94倍，但脑脊液AUC0→6h为静注和灌胃的1.3和2.3倍；大鼠鼻腔给药后大脑、海马、小脑、左右嗅球的AUC0→6h分别为静注的1.5，1.3，1.0，1.2和1.0倍，为灌胃的2.7，2.2，1.9，3.1和2.6倍。

A case of primary TH lymphoma involving the splenium of the corpus callosum and the parietal lobes was presented in a 64 year-old woman with symptoms of increased intracranial pressure.

脑内T细胞淋巴瘤是一种很少见的脑内恶性肿瘤，它的病灶主要在胼胝体、小脑以及大脑的前叶或颞叶：有时后，病灶可延伸到脑室周围的白质与基底核。

Chiari malformations are a spectrum of anomalies associated with a reduction of posterior cranial fossa volumes and CSF while conserving overall brain volume. Chiari I malformations refer to a greater than 5 mm herniation of the cerebellar tonsils down through the foramen magnum.

chiari畸形是由于后颅窝容积及脑脊液减小而与正常的脑容积不匹配造成的一系列的异常病变的统称。chiariI型畸形是指小脑扁桃体下疝超过枕骨大孔5mm以上。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
