白血病

The present study was undertaken to observe experimental myeloid leukosis induced with IMC_(10200) strain ALV-J which was isolated originally from a normal broiler breeder.

对分离自肉种鸡群亚临床感染的J亚群禽白血病病毒IMC10 2 0 0 株进行了实验感染诱发禽骨髓性白血病的病理学研究。

The enzyme linked immunosorbent assayhas been done to detect Avain Leukosis Virus in the albumen from two flocks of chicken and one Marek's disease vaccine. The percent sample positive for ALV in one flock is 11%, the other is 29%.

用酶联免疫吸附试验，对2群鸡的鸡蛋清和1株鸡的马立克氏病疫苗进行检测，发现2群鸡的鸡蛋清中，鸡白血病病毒的阳性率分别是11％和29％，鸡马立克氏病冻干苗隐藏鸡白血病病毒群体特异性抗原的阳性率为100％。

Avian Leukosis Virus Subgroup J is a new kind of retrovirus which infects meat-type chickens, ALV-J was first reported as a new subgroup of ALV by Payne in 1991. It seriously influnenced the development of broilers industry.

J亚群禽白血病病毒(Subgroup J of Avian Leukosis Virus，ALV-J)是上世纪80年代末从肉用型鸡中分离鉴定出来的禽白血病病毒(Avian Leukosis Virus， ALV)新的亚群，严重影响了肉鸡业的健康发展。

To determine the extent of avian leukosis virus infection in China in 2009, 178 suspected ALV samples were collected from 39 chicken farms in eight provinces and examined by polymerase chain reaction with ALV-A, ALV-B and ALV-J gene specific primers.

为了解自2009年年初以来国内一些地区禽白血病流行情况及流行毒株的分子特征，我们从湖北、黑龙江、山东、辽宁、吉林、广东、宁夏、安徽8个省区39个鸡场采集疑似禽白血病病料样品178份，用ALV-A、ALV-B和ALV-J特异性引物，通过PCR方法进行检测。

Results Among the 160 cases of AL, 112 were acute lymphoblastic leukemia and 48 were acute myelogenous leukemia.

结果 1 6 0例AL中，急性淋巴细胞白血病 1 1 2例，急性髓细胞白血病 4 8例。

Objective To explore factors for differentiating non-Hodgkins lymphoma cell leukemia and acute lymphoblastic leukemia.

目的 对非霍奇金淋巴瘤细胞性白血病与急性淋巴细胞白血病进行鉴别诊断。

There were no expression of CD133 in chronic neutrophilic leukemia and chronic lymphocytic leukemia patients.

慢性中性粒细胞白血病和慢性淋巴细胞白血病均未发现CD133的阳性表达。

An subgroup J avian leukosis virus,designated as SCAU-0901,was isolated and identified by histopathological observation,DF-1 cell culture,ELISA test,PCR and immunofluorescence assay specific to ALV-J from Mahuang broiler breeder suspected with ALV infection.

在组织病理学观察的基础上，经接种DF-1细胞系、ELISA抗原检测、聚合酶链式反应以及亚群特异性免疫荧光试验，从送检的疑似禽白血病感染的麻黄肉种鸡中分离并鉴定出1株J亚群禽白血病病毒，命名为SCAU-0901。

In the past two decades immence amount of data have demonstrated to behigh levels of sFR in serum of megaloblastic anemia and leukemia,andshown to be two kind FBPs of FR and RFC on leukemic cells,but thesignificance of RFC are unknown completely.

经过近20年研究已证实，在巨幼细胞贫血、白血病等患者血清中sFR水平升高，同时也发现在白血病细胞膜上存在有两种FBP，即FR和RFC，其意义不完全清楚。

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。
