颞叶脑桥的

Results MRI findings of central neurocytoma are specific in 5 cases. The ganglioglioma was found in the tempora and occipital lobe in 7 cases,in the brainstem in 1 case, cystic-solid tumor was observed in 5 cases with extramural nodule in 3 cases, obviously thickened gyri were revealed in 1 cases and central necrosis in 2 cases.The 3 cases of Lhermitte-Duclos disease include the specific molecular layer imaging features.

结果 5例中枢神经细胞瘤有一定的MRI特征，3例诊断正确。8例神经节细胞胶质瘤中，7例位于或主要位于颞、枕叶，1例位于桥脑和延髓，表现为囊实性者5例，实性部分位于囊外的有3例，呈实性表现为局部脑回增厚者1例，囊变坏死明显者2例。3例小脑发育不良性节细胞瘤有特征性的条纹状或分层状表现。

Results The clinical manifestations of TOBS comprised transient unconsciousness, vertigo, dyskinesia of eyeball, abnormality of pupils, dyskinesia of limbs, hemianopsia or cortical blindness, ataxia and memory impairment. MRI showed the local infarction in thalami, cerebellum, midbrain, pons, occipital lobe, temporal inner surface. The features of DSA were occlusion or stenosis in basilar artery and vertebral artery.

结果 TOBS的临床主要表现为一过性意识障碍、眩晕、眼球运动障碍及瞳孔的变化、肢体运动障碍、偏盲或皮质盲、共济失调及记忆功能损害；磁共振显示梗死灶在丘脑、小脑、中脑、脑桥、枕叶、颞叶内侧面；数字减影血管造影显示为基底动脉及椎动脉闭塞或狭窄。

There were no statistically differences between the 8th~ 14thday, the 15th - 21th day post-BC and the control group. During the rt~24tkday post-BC , pycnosis degeneration or necrosis neurons of the locus cerebral cortex, dorsal hippocampus, dentate fornix were significantly increased, then decreased gradually, but recovered to normal by the 24thday after BC, and especially in parietal cortex and piriform cortex the necrosis neurons were significantly increased than temporal cortex , and there were no statistically difference berween the left and the right side. Pycnosis degeneration or necrosis neurons in the brainstem reticular formation were markedly increased in the 4thday after BC, and there were no statistically difference among the other groups and the control group.

与对照组相比，BC后在大脑皮质、背侧海马和齿状回部位，固缩变性和不完全坏死细胞数先显著增加(P＜0.05)，然后逐渐减少，至24d基本恢复正常；顶叶、梨状皮质比颞叶皮质变性坏死细胞多，差异有高度显著性(P＜0.01)；大脑左侧比右侧变性坏死细胞稍少但差异无显著性；在BC后4d，脑桥核、斜方体核平面的脑干网状结构中固缩变性和不完全坏死细胞数明显增多(P＜0.05)，其它组间无显著性差异。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
