Results: The light microscope pictures of group A(no ［α-32P］ ATP in the perfusate) showed that there was no specially labeled silver pellet in or out of rat liver cell. But the light microscope pictures of group B (37 MBq ［α- 32P］ATP in the perfusate) showed that distribution of numerous ［α-32P］ATP autoradiographic silver pellets in rat liver cell, and no autoradiographic silver pellet was found in the hepatic sinus and vessel.

结果：灌流液中不加［α-32P］ATP的A组光镜照片显示大鼠肝细胞内外均未见特异性标记银粒显影，而灌流液中含37 MBq［α-32P］ATP的B组光镜照片显示大鼠肝细胞内可见多个大小不等的［α-32P］ATP自显影银粒分布，而肝窦及肝小叶中央静脉等血管内则几乎无黑色自显影银粒分布。

Debris necrosis of lymph node is not the specific changes of KD. In the tuberculosis of lymph node,① debris necrosis is obvious, but it tends to be caseous nercrosis;② histiocytes, macrophages and foam cells are hyperplasia in the necrotic area or lymph sinus, moreover, epithelioid cells can be found and they tend to be form granuloma;③ numbers of neutrophils infiltrate in the necrotic area;④ the etiologic assay of acid fast bacterium tuberculosis bacterium is positive;⑤ typical clinical manifestation is insufficient.

淋巴结碎屑性坏死并非KD特有病变，诊断KD需先除外有明显碎屑性坏死的淋巴结结核病，后者主要表现：①碎屑性坏死虽明显，但趋于干酪样坏死；②坏死区内或同时在淋巴窦内，组织细胞、巨噬细胞和泡沫细胞增生，并演变为上皮样细胞和趋于肉芽肿形成；③坏死灶内、外可有数量不等的中性粒细胞浸润；④抗酸杆菌／结核杆菌病原学检测阳性；⑤缺乏KD的典型临床过程。

Atrial fibrillation of variable duration precedes the onset of AFL in almost all instances; during AF, the functional components needed to complete the AFL re-entrant circuit, principally a line of block between the vena cavae, are formed; if this LoB does not form, classical AFL does not develop.

在几乎所有的病例中，持续时间多变的房颤先于AFL发生，房颤时结束AFL折返环的功能成分，主要是静脉窦之间线性隔断，业已形成。如果该阻断不能形成，典型AFL不能进展。

Skull radiographs may show the typical "tram track" calcifications in apposing gyri.

颅骨平片可以显示典型的轨道样钙化，CT可以显示邻近的板障增厚，同侧的副鼻窦及乳突窦房过度气化

The Second Affiliated Hospital, Medical School of Xian Jiaotong University, Xian 710004, ChinaABSTRACT: Objective To observe the acute homodynamic changes of biventricular pacing in patients with sick sinus syndrome and investigate the Ca2+ changes during absolute refractory period electrical stimulation by applying computer simulation.

目的 观察双心室起搏对病态窦房结综合征(sick sinus syndrome， SSS)患者的急性血液动力学变化及心脏绝对不应期电刺激对心功能的影响，通过计算机仿真研究，探讨绝对不应期电刺激的离子流作用机制。

Pilonidal sinuses are most common in young adults, and are rarely seen in children or people over 40 years old.

毛窦是最常见的在年轻的成年人，并罕见的在儿童或人40岁以上。

The distance between rear part of posterior semicircular canal andanterior margin of the sigmoid sinus increased by 4.45 mm(57.8%),exposure areas ofposterior fossa dura increased by 157.32 mm~2 (64.3%)and operative angle of visionwas 329.6% that of retrolabyrinthine approach when performing PLPA approachcompared with retrolabyrinthine approach.

PLPA入路与迷路后入路相比，半规管后端与乙状窦前缘的距离较迷路后入路增加了4.45 mm (57.8%)，后颅窝硬膜的暴露面积增加了157.32 mm~2 (64.3%)，手术视角为迷路后入路的329.6%。

Histological observation showed that normal structure was observed in all the groups before being harvested or after being preserved for 30 minutes. However, the more severe structure damage was observed in HPCs or hepatic sinusoidal cells with the more prolonged rewarm ischemia.

形态学观察发现，四组供肝于离体前及低温保存30分钟时的组织结构均无明显异常改变；而在复温缺血期间，各组供肝肝实质细胞及肝窦内皮细胞则表现有不同程度的结构损伤，且在程度上也与复温缺血时间呈明显的平行关系。

Normal rat embryos and embryos with ARM from gestational days 12.5to 20were sectioned serially and sagittally and stained with HE to observe development of cloaca and anorectum continually and contrastively.

2·结果①胚胎发育：泄殖腔发育过程中，胎龄15天前的正常鼠胚，尿直肠隔将泄殖腔分为腹侧的尿生殖窦和背侧的直肠两部分，二者共同相通于泄殖腔管。

The control of the heartbeat starts with a small clump of muscle cells in the upper right chamber, called the sinoatrial node.

控制心跳开始与一小丛的肌肉细胞在右上角的会议厅内，所谓的窦房结。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
