Cases 1-5 who presented with spastic paraparesis and other prominent upper motor neurone signs showed high signal on T1-weighted images in the centrum semiovale, corona radiata and posterior limb of the internal capsule which corresponded to the large myelinated fibres of the corticospinal tract Fig.

病例1~5患者表现为下肢痉挛性轻瘫和其他一些明显的上运动神经元症状体征，在T1像上于半卵圆中心、放射冠、内囊后肢处的皮质脊髓束大有髓纤维走行区均可见高信号病灶（图1），在T2、PdWI像上也可见自放射冠延伸至大脑脚的高信号病灶。

Results Pycnosis and deep staining of neurons, deposits of synapse vesicles and bluring of synapses, fusion and dissociatio of myelin sheaths which were exposed to 10, 50 and 90 mW/cm^2 HPM were observed. The contents of the above four amino acids elevated more markedly on 6 h than those of controls, but on 1 d only the elevation of GABA and glycine after exposure to 10 and 50 mW/cm^2 HPM was observed.

结果平均功率密度10，50和90mW/平方公分S波段高功率微波可引起大脑皮层神经元固缩、深染，尼氏体减少；突触结构模糊，囊泡堆积；髓鞘融合、解离等。10和50mW/平方公分组照后6h大脑皮层上述4种氨基酸含量均显著增高(P.01)；而照后ld仅见γ-氨基丁酸和甘氨酸含量仍较高(P.01)。

Objective: The purposes of the present study are as follows: 1 To study the effect of direct contact with VSMC on transdifferentiation of MSC; 2 To construct MSC of Dual-stable expression of AT2R gene medicated by tetracycline regulatable system.; 3 To investigate the effects of AT2R gene medicated by tetracycline regulatable system on neointimal hyperplasia in rat carotid arteries after balloon angioplasty.

本实验体外观察MSC与VSMC在直接接触培养下的分化情况，并以MSC为载体，通过体外细胞基因转染及筛选，获得双重稳定受到强力霉素调控表达AT2R基因的MSC，将此受到调控表达的AT2R基因导入大鼠颈动脉球囊损伤动物模型中，观察MSC细胞移植实现AT2R基因在体可调控表达在新生内膜中形成的作用及潜在意义。

When the soil relative water content is 80%, the chloroplast and mitochondria cristae were regular. When the soil relative water content is 100%and 60%, the chloroplasts became roud in shape.There were bigger giqantic starch grains and fat droplets in the chloroplasts. Mitochondria cristae became swollen. When the soil relative water content is 40%and 20%, thylakoids became swollen and disorder in leaf cell, mitochondria cristae became obscured .

5在土壤相对含水量为80%时，叶绿体和线粒体能维持其结构和膜的完整性；在土壤含水量为100%和60%时，毛桃和石头扁桃叶片中的叶绿体变圆，出现大颗粒淀粉和脂类小滴，线粒体嵴膨胀；在土壤含水量为40%和20%时，叶绿体类囊体紊乱肿胀，线粒体嵴模糊或溶解。

The sheetlike layers of the thylakoids are called lamellae.

类囊体上的层片叫做片层。

The sac structure projected through the pollen aperture possesses the typical nature of transfer cell, i. e complex lybrinthian wall ingrowth and abundant mitochondria, RER, dicotysomes and ribosomes under the wall. Its outer surface is closely related to the tapetal protoplast. The accumulation of storaged material in pollen start at the area near the apertures. Above restults indicate the pollen apertures may be the"door"from where nutrition flows into pollen in P. hortorum.

绒毡层物质向花粉粒的短途运输明显的表现在花粉的萌发孔区，一方面形成向外突起的囊腔，另一方面在这里具有发达的壁迷宫，而且迷宫下具丰富的线粒体，RER和高尔基体等细胞器，此外花粉内贮藏物的大量积累首先从萌发孔附近开始以及萌发孔处与绒毡层有紧密接触都说明天竺葵花粉萌发孔可能是物质进入花粉的&门户&。

The results showed: four devices flower pollen sacs, anther wall conforms to the basic, from epidermis, the indoor wall, middle (2-3 layers) and tapetal composition tapetum to glandular type.

对悬铃木小孢子发生及雄配子体发育过程进行了观察，结果表明：花药具4个花粉囊，花药壁发育为基本型，由表皮、药室内壁、中层（2-3层）和绒毡层组成，绒毡层为腺质型。

Once this is done, the thecal sac can be easily retracted to provide better exposure of the posterior portion of the vertebral body and the intervertebral discs.

经过这些操作后，就可以较容易的收缩硬膜囊以便显露椎体与椎间盘的后面部分。

Pathological conditions of the c ord, thecal sac, v ertebral bodies

现和确定脊髓、鞘膜囊、椎体及椎间盘的病理状况。

Marine birnavirus, a member of the genus Aquabirnavirus, family Birnaviridae, is an unenveloped icosahedral virus with two genomes of double-stranded RNA.

海生双RNA病毒是类无囊膜、正二十面体、带有两节段双链RNA基因组的病毒，属于双RNA病毒科水生双RNA病毒属成员。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
