Aian influenza irus was isolated from the caecal tonsil, faeces, and kidney of the domestic ducks. The isolated irus was identified as a highly pathogenic H5N1, with a haemagglutinin proteolytic cleaage site deduced amino acid sequence of ... QREKRKKR/GLFGAIAG ... In order to determine the pathogenicity of the isolate, eight 6-week-old specific pathogen free chickens were inoculated intraenously with the irus, and all birds died within 24 h after inoculation.

病毒抗原可以从鸭的盲肠，扁桃体，肾脏及粪便分离出来，并且确定这种病毒是高致病性的H5N1，还从血凝素蛋白分解位点推断出病毒的氨基酸序列，为了了解独立群的发病机理，对8只6周龄鸡静脉注射这种病毒，结果所有的均在注射后24小时死亡。

The high prevalence of resistance to chicken sera, fimbriae F1, temperature-sensitive hemagglutinin in high pathogenic isolates suggested importance of these phenotypes in the pathogenesis of colibacillosis.

结果显示禽源大肠杆菌的致病性与其血清耐受能力、鸡红细胞MSHA菌手的表达和温度敏感性血凝素的表达呈一定的相关关系。

The major clinical features of the case were viral pneumonia with rapidly developed leukopenia and lymphopenia.

病例的气管吸取物A/H5N1的HA和NA基因阳性，分离到的A/Anhui/1/2005（H5N1）的8个基因节段均为禽源的，血凝素抗原的受体链接肽仍为多个碱性氨基酸。

The hemagglutinating activity of CCL was independent of the divalent cation Ca(superscript 2+) CGL displayed mitogenic effect on BALB/c splenocytes, inhibited angiotensin converting enzyme with IC value of 6.82mg/mL, and improved the peristalsis of a rabbit ileum.

其血凝活性不依赖钙离子的存在。在植物凝集素存在的条件下，CGL具有体外促进小鼠脾细胞增殖的活性。同时，它还具有抑制酶活性，其抑制50% ACE的浓度(IC50)动为6.82mg/ml和促进体外离体兔回肠蠕动的作用。

RESULTS: Analysis of T cell activation in vitro revealed that preincubation of PBMC with 100 μmol/L gossypol could completely inhibit the expression of early activation marker CD69 on CD3+ T cells in response to 10 mg/L PHA, and block T cell activation by 10-7 mol/L PDB as well.

结果： 100 μmol/L的棉酚预先与T细胞温育，能完全抑制10 mg/L植物血凝素刺激的CD3＋T细胞活化抗原CD69的表达，又可阻断10－7 mol/L佛波醇酯对T细胞的活化作用。

The assay, which was based on primers and TaqMan-MGB probes selected from highly conserved regions of the hemagglutinin gene of avain influenza virus subtype H5, was optimized in a reaction system and a condition to improve the sensitivity, specificity and accuracy. In addition, colone technology was used to develop a quantitative PCR format with virus copies amount.

针对H5亚型禽流感病毒血凝素基因保守区域设计特异性引物与TaqMan-MGB荧光探针，筛选并优化荧光定量RT-PCR反应体系与反应条件，用以提高方法的特异性、敏感性与准确性；并通过体外克隆技术建立病毒基因拷贝数进行定量分析。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
