颅盖

Anencephaly, the single most common open neural tube defect, is characterized by the absence of the cerebral hemispheres and the lack of bony calarium aboe the orbits Fig.

无脑畸形，最常见的单一的开放性神经管缺损，其特点是无大脑半球且没有眼眶以上的骨性颅盖（图10-37A-B和图10-37C）。胎儿有正常的中脑和后颅窝，但大脑半球未正常发育。

METHODS: The calvarium bone of new born rats was digested with bacterial collagenase and cultured to obtain osteoblasts and SP with different concentrations was then added.

采用新生大鼠颅盖骨消化法培养成骨细胞，再加入不同浓度的SP，观察细胞生长数量，测定碱性磷酸酶活性及观察细胞周期变化。

METHODS: The calvarium bone of newborn rats was digested with bacterial collagenase and cultured to obtain osteoblasts and SP with different concentrations was then added. The proliferation and activity changes of the osteoblasts were identified by counting the cells, determining the ALP activity and observing the changes of cell cycle.

Magnetic resonance imaging of the brain demonstrated a right parietal lobe abscess and a sinus tract extending through the overlying calvarium.

颅部MRI证实右侧顶骨耳垂部存在脓肿和穿过覆盖该处颅盖骨的窦道。

Cut the scalp along the sagittal line and turn it to two sides, take down the calvarium of one side along supraorbital margin, key point, the superior margin of zygomatic arch, external occipital protuberance and sagittal suture.

将头皮沿正中矢状线切开并将其翻向两侧，沿一侧眶上缘、关键点、颧弓上缘和枕外隆突的连线及矢状缝取下一侧颅盖。

Results Four basal veins lacked of anterior segment, 22 ran closely behind the fasciculus opticus, and four were distant from the fasciculus opticus.

最后去除颅盖骨，在游离的脑标本上对基底静脉本干及其属支进行观察、测量，统计相关数据。

Microcephaly, characterized by a reduction of brain mass and head size with an intact bony calarium, is defined as a fetal head circumference either 2^57 or 3^58 standard deiations below the mean of that expected for menstrual age.

具有脑质量减少、头体积变小、有完好颅盖骨特征的头小畸形的定义是胎儿头围在胎龄预期均值的2^57 或3^58个标准差以下。

B The micropipette aspiration technique was used to study the effects of cyclic stretching on the mechanical property of rat calvirial osteoblasts which were loaded at 500με, 1000μεand 1500μεrespectively with the frequency of 0.4Hz.

利用微管吸吮技术研究应变分别为500με、1000με和1500με，频率为0.4Hz的周期性拉伸刺激对大鼠颅盖骨中分离出的成骨细胞的力学特性的影响。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
