查询词典 leucosis

This study that observed the expression and distribution of 4 apoptotic factors, relation apoptotic factor with apoptosis, changes of T and B subgroup, and changes of molecular pathology in 14 cows suffering from enzootic bovine leucosis from several resides was detected by histochemistry, TUNEL technology, immune-fluorescent flow cytometry and so on. The aim of this experiment supplies theoretic basis for preventive and therapy of EBL, and consult dates for T lymphoid cell leucosis of human being .

本研究检查并剖检了14例临床与实验室诊断为EBL的病牛，观察分析了肿瘤发生的情况和特征，采用免疫组织化学ABC法、原位末端标记TUNEL技术和免疫荧光流式细胞检测法等技术，从EBL肿瘤细胞凋亡特性入手，围绕4种凋亡因子和几种免疫相关因子与EBL肿瘤发生的关系及其在诊治方面的应用进行了首次有价值的探索，其目的在于为防治EBL提供科学的理论依据，同时，也将为人类T细胞白血病Ⅰ。

Subgroup A has long been recognized as a carcinogenic disease in chickens, mainly called lymphoid leucosis.

其中引起淋巴球性白血病的A亚群是最常见的外源性病毒。

Avian leucosis virus is one of the member of retroviruses, which has been divided into 10 subgroups of A to J.

家禽白血病(avian leucosis， AL)是由家禽白血病病毒(avian leucosis virus， ALV)引起，依ALV感染宿主的不同、病毒干扰的现象及病毒封套蛋白质上的抗原性不同，可分成十个亚群。

However, measuring p27 in the blood at ages 1 and 6 weeks old by ELISA could be used for discriminating the ALV-J-infected flocks from non-infective flocks having endogenous non-tumorigenic avian leucosis. Because the p27 of the former increases but that of the latter decreases during young ages.

然而应用ALV-J可在1周龄内鸡群中迅速传播的特性，感染鸡群早期的p27会上升，因此检测1周龄及6周龄鸡只血液p27的升高，可以与无ALV-J感染只含内源性病毒的鸡群区别。

Avian leucosis virus ; monoclonal antibody ; DAS-ELISA

禽白血病病毒；单抗；双抗体夹心法ELISA

Avian leukosis virus subgroup J ; IMC_（10200） strain ; experimental ; myeloid leucosis

J亚群禽白血病病毒； IMC10200株；实验性；骨髓性白血病

A double-antibody sandwich ELISAemploying monoclonal antibody 5G5 was developed for detection of P27 antigen of avian leucosis virus.The limit of viral antigens detected was 5?

利用原核表达的禽白血病病毒P27蛋白作为抗原制备的单抗作为包被抗体，以制的酶标兔抗P27作为酶标抗体，在国内首次建立了检测ALV抗原的双抗体夹心ELISA方法。

The recombinant RSV vaccinia virus VMS11G75F was constructed strictly according to the rules of biological products and all tests for contamination by bacteria, Chicken leucosis virus and mycoplasma gave negative results, so that vaccinia recombinant VMS11G75F could be a candidate of recombinant RSV live vaccine for human test.

HSV重组痘苗病毒VMS11G75F是严格按照人用疫苗株程序构建而成，并对多种外源因子污染(包括：细菌、鸡白血病病毒、支原体等)进行了检查，均为阴性，因此是一株可供人体实验观察的RSV基因工程活疫苗候选株。

To explore the influence of reticuloendotheliosis virus and subgroup J avian leucosis virus infection on chicken cellular immunity,the mitogenic response to ConA of blood and spleen lymphocytes tested and analyzed with 3H-thymidine(3H-TdR) incorporation assay at different intervals after infection or co-infection of single or both viruses.

自1974年分离出网状内皮增生症病毒[1]和1991年分离出禽白血病病毒J亚群[2]以来，在我国先后分离出不同毒株的REV和ALV-J，并开展了病原学、流行病学、致病性和免疫反应以及预防诊断等方面的研究，揭示出不同的致病性，并且确认它们都可造成感染鸡群免疫抑制，成为一些

In order to discuss the interaction of viremia and antibody caused by reticuloendotheliosis and avian leucosis virus of subgroup J, REV, ALV-J and REV+ALV-J were injected to SPF chicken at 2 d separately, then tested the viremia and antibody dynamically for 7 weeks. The results indicated that compared with single infection, the dynamic viremia level of REV and ALV-J wasn't obviously different when coinfected.

为了研究禽网状内皮增生病病毒、禽J亚群白血病病毒共感染时对彼此病毒血症及抗体反应的影响，2日龄SPF鸡分别接种REV、ALV-J或同时2种病毒造成共感染，对各感染组7周内的病毒血症及抗体反应进行动态检测。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
