病毒

National Cancer Institute. Dr. Robert C. Gallo, which is a well-known virologist, he led the team in early 1980 discovered the first human retrovirus - human T-cell leukemia virus.

其中的罗伯特·加洛是位著名病毒学家，他所领导的团队早在1980年发现了第一种人类逆转录病毒——人T细胞白血病病毒。

Rouen University, a virologist at the Cameroon-born patients who found a new type Ⅰ HIV virus subtype, it is different from the above-mentioned three kinds of subtypes.

鲁昂大学病毒学家在一名喀麦隆裔病人身上发现一种新的Ⅰ型HIV病毒亚型，它不同与上述的3种亚型病毒。

This virus is spread similar to the hepatitis A virus and causes acute disease similar to the others.

这种病毒的传播类似于甲型肝炎病毒，引起急性肝炎也与其他病毒引起的相似。

We observed the cytopathic effect in rabbit kidney cells culture to isolate viruses,then typed viruses by monoclonal antibody and flurescence antinody technique. In the 1,016 .scraping specimens from cervicitis, vulvitis, vaginit;s and cervlcal cancer, we found72 cases of HSV infection the positive rate was 7. 08% The highest positive rate was 8.7% that was in cervical cancer.

本文应用细胞培养观察细胞病变的方法来分离病毒，再用单克隆抗体及荧光抗体对病毒进行分型，在西宁地区1016例妇科疾病所取标本中（包括宫颈炎，外阴炎，阴道炎及宫颈癌等），共发现单纯疱疹病毒阳性标本72例，阳性率为7.08％，而宫颈癌中阳性率最高为8.7％。

METHODS: MyoD cDNA fragments were extracted from plasmids pEMSV-MyoD with polymerase chain reaction, and PCR was used to clone the whole-length gene of MyoD. After adding CACC sequence at 5' end, MyoD gene was cloned by orient topology into transfer ventor, pENTR/D-TOPO. Objective gene was transferred into adenoviral expression vector DNA via pENTR/D-TOPO vector. The recombinant adenoviral vectors transfected into HEK293A cells by using lipofectamine were packaged and amplified.

从pEMSV-MyoD质粒上用聚合酶链反应法扩增出MyoD cDNA片段，再通过聚合酶链反应使MyoD基因加上CACC序列接头，经过定向拓扑克隆使目的基因连接到转移载体上，再通过LR酶促反应，将目的基因转移到腺病毒表达载体DNA上，获得MyoD基因重组的腺病毒DNA，用脂质体转染法转染HEK293A细胞，包装扩增出MyoD基因重组的腺病毒。

As a matter of fact, the viruses of highly pathogenic bird flu do widely spread all over the wildfowl of nature and live together with wildfowl in peace for a long time.

事实是这样的：高致病性禽流感病毒的确广泛存在于自然界的野禽中，与野禽长期和平共处。100多年前，人们开始认识禽流感病毒；50多年前，分离出了H5N1病毒。

EB virus is a human B-lymphocyte affinitive Herpesviridae, discovered in 1964 by Epstein and Barr during their research of African children malignant lymphoma, which is now defined as type I carcinogen by International Agency for Research on Cancer.

EB病毒(Epstein-Barr Virus， EBV)属疱疹病毒科，1964年由Epstein和Barr在研究非洲儿童恶性淋巴瘤时发现的一种感染人类B淋巴细胞的疱疹病毒，被国际癌症研究机构（International Agency for Research on Cancer， IARC）归为I类致癌物质，在全世界人群中感染率超过90%。

论文摘要： EB病毒(Epstein-Barr Virus， EBV)属疱疹病毒科，1964年由Epstein和Barr在研究非洲儿童恶性淋巴瘤时发现的一种感染人类B淋巴细胞的疱疹病毒，被国际癌症研究机构（International Agency for Research on Cancer， IARC）归为I类致癌物质，在全世界人群中感染率超过90%。

Polyhedrin and virion, which were isolated and purified from Agrotis setegum nuclear polyhedrosis virus, are administered to 3-instar Heliothis armigera larvae with Heliothis armigera nuclear polyhedrosis virus. Both polyhedrin and virion could increase mortality of H. armigera larvae, shorten half mortality time and decrease half mortality concentration.

对黄地老虎核型多角体病毒的多角体蛋白和病毒粒子组分进行分离纯化，分别与棉铃虫核型多角体病毒混合感染三龄棉铃虫幼虫，发现此二种组分均能够提高棉铃虫幼虫的死亡率，缩短半致死时间，降低半致死浓度。

Virus was also cultured in allantoic cavity of chicken embryo with statistically significant HA titer at 1:6.8 as compared with virus control group (P.01) incubated 24 hours after injected with MEK first then injected with IBV.

在鸡胚尿囊腔中，先注入MEK孵育24 h后，再注入B型流感病毒的鸡胚也培养出病毒，HA滴度为1：6.8，与病毒对照组比较P.01，有统计学意义。

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％。
