MSCT may play important roles in appreciating the influence of fibrous dysplasia on pterygopalatine fossa and its communications.

MSCT在评价骨纤维异常增殖症对翼腭窝及其通道的影响方面具有较高的临床应用价值。

Methods32 Wistar male rats were used to induce focal cerebral ischemia according to Longa's method.

3 2只Wistar雄性大鼠，按照Longa的线栓法制作局部脑缺血模型，但在放入栓塞线时不结扎翼腭动脉，通过局部脑血流监测、动物行为学评分、脑含水量测定、红四氮唑染色和病理学检查等方法评价该模型的可靠性。

Objective: To observe the age changes of the age changes of the expression of nitric oxide synthase in pterygopalatine ganglion , otic ganglion and the fibers innervating the cerebral vessels of rats.

目的：观察大鼠翼腭神经节、耳神经节及脑底动脉壁神经纤维一氧化氮合酶表达的年龄变化规律。

The VIP IR-neurons in the pterygopalatine ganglion may be involved in the mechanism of AR.

翼腭神经节内VIP神经元可能参与变应性鼻炎的发病。

Objective: To explore the clinical application of multislice spiral CT in evaluating the involvement of pterygopalatine fossa and its communications by fibrous dysplasia.

目的：探讨多层螺旋CT在评价骨纤维异常增殖症对翼腭窝及其通道的影响及其临床应用价值。

Transverse section al anatomy and clinical significance of the pterygopalatine space

方法选用成年尸体头颈部20例制成连续横断面，观察翼腭间隙及其结构的解剖学关系，利用游标卡尺及求积仪分别测量其长径、宽径和面积。

The 3 endoscopic approaches are safe and effective for resection of different pterygopalatine fossa lesions and foramen rotundum serves as a landmark for safe management of the pterygopalatine fossa.

3种手术进路能有效地处理不同的翼腭窝病变；圆孔可以作为手术中安全范围标志。

The CT and MRI results showed soft tissue disease focus was found and its boundary was not clear, enhancement CT and MRI scanning showed 8 and 11 cases had low and middle degrees enhancement,respectively. The pathological changes in 22 cases often be outside the nasal cavity and paranasal sinus but infringed upon the pterygopalatine fossa, orbit.

CT、MRI 27例表现边界不清的软组织病灶，CT、MRI增强扫描分别为8、11例表现为低至中度强化。22例病变超出鼻腔鼻窦而侵犯翼腭窝、眼眶等窦外结构。

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。
