The virus-free rate of ACLSV and PDV were 71.6% and 73.0% respectively on 0.3-0.4 mm shoot tip based on the plant indicator identification, The test showed that the virvs-free and rapid propagation technique of Prunus humilis Bunge.

应用指示植物鉴定法进行病毒检测显示，0.3~0.4mm茎尖培养对苹果褪绿斑病毒和李矮缩病毒的脱毒率分别为71.6%和73.0%。

Some consider these infectors to be a third category of viruses, while others consider them to be a sub-category of the file infectors.

有些人把这种感染型病毒看作是第三类病毒，而另一些人则把它看作是文件感染型病毒的子类。

Moreover, in order to make clear whether IV infection touches off the cause and its pathogenesis of artherosclerosis inflammatory reaction. The study also uses IV of type A1 and A3 to infect repeatedly Jimpy mice with E gene defect, to observe AS histology change of Jimpy mice aorta and detect the change of IV antibody and inflammatory reaction medium (eg.TNF-α, IL-1) in Jimpy mice serum and express of monocyte chemotactic factor( MCF-1) and nuclear factor kB in Jimpy mice aorta tissue .

另外，为了弄清流感病毒感染是否是触发动脉粥样硬化炎症反应的发生原因及其机理，本研究还用A1、A3型流感病毒反复感染载脂蛋白E基因缺陷小鼠，观察小鼠主动脉的动脉粥样硬化组织学改变，并检测小鼠血清中流感病毒抗体、炎症反应介质（如TNF-a、IL-1等）变化情况以及小鼠主动脉组织中的单核细胞趋化因子-1（MCP-1）和核转录因子kB表达情况。

Any of a group of RNA-containing viruses, including those that cause influenza, typically having an affinity for certain mucins and causing agglutination of red blood cells.

粘液病毒一组含核醣核酸病毒的任一种，包括引起流行性感冒的病毒，通常与某种粘蛋白有关，而且会导致血红细胞的凝集

Objective To study the effects of 20/21 bp partial deletion mutation (from nt 1 748 or nt 1 747 to nt 1 767) in the core promoter region of hepatitis B virus genome complicated by precore stop condon mutation at nt 1 896 on the expression of the viral antigens.

目的为研究乙型肝炎病毒核心启动子20/21bp部分缺失(nt1748/1747至nt1767)及同时存在的A1896点变异对病毒抗原表达的影响。方法利用前期构建的HBV全基因的重组载体转染HepG2细胞后，对病毒抗原进行ELISA检测及Western-blotting分析。

A CEVd strain was isolated from Heibei province in China and its complete nucleotide sequences were identified.Accounting to the characteristic of structure of viroid, the nucleic acid from the positive material was detected by bidirectional PAGE.

柑桔裂皮类病毒快速检测技术体系的建立聚丙烯酰胺双向凝胶电泳法检测：将从阳性材料上提取的类病毒核酸，先在6％的聚丙烯酰胺非变性胶上进行第一向电泳，然后切割含类病毒分子的胶条，在变性条件下进行垂直或反向电泳，最后银染观察。

Viroids replicate within the plant cell and cause characteristic disease symptoms; examples are the potato spindle tuber viroid and the hop stunt viroid.

类病毒的复制在植物细胞内进行，能够导致典型病症。例如马铃薯纤块茎类病毒和蛇麻草矮病类病毒。

However, the host cell proteins and mechanisms responsible for intracellular transport of VP40 prior to its contribution to virion formation remain to be elucidated.

然而，宿主细胞与病毒蛋白VP40的作用，以及VP40在病毒胞内运输与病毒颗粒形成过程中的作用还不清楚。

CP might be involved in viral cell-to-cell movement,but it would not be usedfor virion assembly to pass through PD.

病毒的短距离运输需要CP的参与，但不一定是形成病毒颗粒形式，病毒可能是以核酸-蛋白的复合体形式进行胞间运动。

The infectivity of TMV recovered by dialysis from incubation with anthraquinone glycosides in vitro has been reduced in contrast to infectivity of TMV control, it seems that anthraquinone glycosides have direct viricidal effect on TMV. The anthraquinone glycosides may interfere recognization of TMV to host receptor when applied before TMV inoculation. The anthraquinone glycosides can inhibit multiplication of TMV in infected leaf discs but did not inhibit infectivity of TMV-RNA in vitro. The control of tobacco mosaic virus disease of N.

总蒽醌甙对TMV混合，对粒体形态无破坏作用，但经透析，其抑制作用仍较高，表明总蒽醌甙与TMV结合能力强不易解离或对粒体具有直接毒害作用；总蒽醌甙预先接种可能影响病毒对侵染位点的识别，对叶圆片中的病毒具有抑制复制的作用，但在体外混合不影响TMV-RNA的侵染活性，可能与总蒽醌甙干扰病毒的衣壳装配过程或影响复制酶的活性有关。

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。
