病毒

How the triple reassortment genes and the European and Asian genes met and mixed is not known, Webby said.

病毒的三重重组基因与欧洲病毒基因以及亚洲病毒基因是如何相遇，又如何融合到一起的？我们并不知道。Webby说。

The longer the virus circulates the way it does in poultry production systems and in ducks, the higher is the probability of exposure of humans and if we are indeed unlucky and have human influenza at the same time, there is increased likelihood of reassortment and therefore of the generation of pandemic.

病毒在禽类生产系统和鸭子中传播的时间越长，人类接触到病毒的可能性越大。如果我们不幸同时患有流感，这两类病毒之间再组合的可能就会增加，因此发生流行病的可能性也会增加。

Results The cytopathic effect induced by influenza virus was inhibited remarkedly,with IC50 of 3.33 mg raw material/ml and TI of 7.48. At the dose of 8～20g raw material/kg body weight,pneumonia induced by influenza virus in mice was inhibited significantly by the water extract.The survival rate was increased remarkedly. Conclusion The water extract from Pitecollobium clypearia Benth.

结果 猴耳环水提取物在体外对流感病毒引起的细胞病变有明显抑制作用，其IC50生药为3.33mg/ml，TI为7.48；在给生药药剂量为8～20g/kg时，对流感病毒所致的小鼠肺部炎症有明显抑制作用，并能明显降低流感病毒感染小鼠的死亡率和延长其存活时间。

Dr. Sandrock said there is no vaccine that will protect against the virus, but he said that if populations are old enough to have experienced the 1968 strain, for instance, they may have a host-adapted MHC?I primed T-cell response with epitopes, is appropriate for viral clearance may confer some protection and result in a mild to moderate disease, where the host would just "feel crummy."

Sandrock医师表示，没有可以抵抗此病毒的疫苗，但他表示，如果一些年纪较大者、曾经历过1968年的病毒株，他们或许有抗原决定位的原发T细胞反应、宿主-后天主要组织相容性复体第一型，适合病毒清除以及赋予一些保护力，造成疾病较轻微或中等，宿主的感觉相当轻微。

Increasing the amount of virus inoculated did not increase the virus bound to the cell. Both the number of cells and concentration of virus could influence the binding which was saturable.

增加加入JEV的量，未见到病毒的结合量有明显增加，提示这种结合是特异的，病毒浓度和细胞数量的变化对病毒与受体的结合反应有一定的影响，结合具有饱和性。

Meanwhile many cases were diagnosed to be sero positive of anti dengue virus. Dengue I virus were also isolated from five cases. RT PCR test also indicated 4 out of 8 samples contained dengue I virus, which was the same type of dengue virus found in the epidemic areas in Guangzhou at the same time of outbreak.

进一步的调查在病例的血标本中分离出5株登革I型病毒，同时用RT—PCR的方法从8份标本中检出4份登革I型病毒阳性，与同期广州市登革热流行的病毒型别一致；取患者的恢复期血清作肥达氏反应，结果抗&O&、&H&的滴度与第一份血相比，均显著下降。

Objective To explore the relationship between the quantities of HBV and the models of serologic markers.

目的 对乙型肝炎病毒DNA载量与HBV血清标志的关系进行研究，探讨乙型肝炎病毒载量与机体免疫反应的关系，为抗病毒治疗提供科学依据。

The virus particles of three isolates were about 60 nmin diameter and closely related serologically. Their dsRNA electrophoretic profiles inagarose gel were similar.

提纯3个病毒分离物的基因组片段，凝胶电泳显示它们相应的基因组片段之间大小极其相似，推测3个病毒分离物可能是同一种病毒。

The HPV DNA related sequences, the expression of HPV capside antigen and relationship between the ultrastructural feature of lesion and diverse types of HPV infection in 35 cases of the cervical pr61iferative lesions(cervical condyloma, cervical cancer)were analyzed on the levels of cell,subcell and molecule by using nucleic acid hybridization, immunohistochemical method and electron microscopic technique.

本研究分别用核酸杂交、免疫组织化学和电子显微镜术等方法从细胞、亚细胞和分子水平上比较分析了35例子宫颈增殖性病变中人乳头瘤病毒DNA相关序列，人乳头瘤病毒衣壳抗原的表达以及病变超微结构变化特征与不同型别人乳头瘤病毒感染之间的关系。

Results The concentration of Chlorogenic acid was 0.05mg/ml, 0.1mg/ml, 0.4mg/ml, 0.8mg/ml respectively, it can respectively inhibit respiratory syncytia virus, Coxsackie B3 virus, adeno-associated 7 virus, adeno-associated 3 virus and Coxsackie B5 virus.

结果 氯原酸浓度分别为0.05mg/ml、0.1mg/ml、0.4mg/ml、0.8mg/ml时，可分别体外抑制合胞病毒、柯萨奇B3、腺病毒7型、腺病毒3型和柯萨奇B5型。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
