Shanghai Veterinary Research Institute,Chinese Academy of Agricultural Sciences,Shanghai 200232,ChinaAbstract: Nine samples from swine abortus were detected by RT-PCR with a pair of primers specific to NS1 gene of Japanese encephalitis virus.

采用反转录聚合酶链式反应方法检测猪流产胎儿病料中的乙型脑炎病毒，并对阳性病料做病毒分离与纯化。

Objective To explore the roles ofα-amanitin in the replication ofhepatitis B virus in HepG2 2.2.15 cell line Methods MTT assay were used to observe the cytotoxicity ofα-amanitin to the HepG 2 2.2.15 cell line.

中文摘要：目的：基于α-鹅膏毒肽的作用机制和乙肝病毒复制转录特点，初步探讨α-鹅膏毒肽对HepG2.2.15细胞的毒性及其对乙型肝炎病毒复制的影响。

Many technical measures have been taken as follows to ensure the safety management: a. operation steps of installing the cross joints are improved to guard against damage on metal sealing and the hanger; b. well logging is applied to gas testing so as to achieve early warning in a scientific way; c. the burning processing unit of QTI3000 is widely used to reduce the bad impact on the environment; d. the articulation of perforating gun is improved to alleviate labor intensity and shorten the perforating time so as to shut down the well promptly in case of any accidents.

在安全技术措施上，改进了坐完井悬挂器操作步骤，避免损坏金属密封，造成悬挂器损坏；将录井技术应用于试气作业，实现了科学预警；推广应用了QTI3000型焚烧处理装置，降低了对环境的不良影响；改进了射孔枪的连接方法，减轻了工人的劳动强度，缩短了起射孔枪时间，能在起钻发生井喷失控前及时控制关井。

Generally, B in the configuration closest cell's DNA conformation, it and the double helix model are similar. A-DNA and when RNA member double helix area as well as duplication forms the DNA-RNA hybrid molecule conformation is close. Z-DNA take the nucleotide dimer as the unit left-hand winding, its principal chain assumes the denticle the shape, therefore.

一般认为，B构型最接近细胞中的DNA构象，它与双螺旋模型非常相似。A－DNA与RNA分子中的双螺旋区以及转录时形成的DNA－RNA杂交分子构象接近。Z－DNA以核苷酸二聚体为单元左向缠绕，其主链呈锯齿形，故名。

A genechip analysis was performed using RNAs derived from embryos injected with squint mRNA, MZoep mutant embryos that are deficient in Nodal signaling, and wildtype embryos at the 30% epiboly stage Transcriptswith at least two-fold changes in expression level between wildtype and the other samples were identifyied In squint mRNA-injected embryos, 265 transcripts show anincreased expression level and 111 have a decreased expression level; in MZoep embryos, the expression of 1 495 transcripts increases while 550 transcripts express at a decreased level.

为鉴定受Nodal信号调控的基因，特别是那些转录因子基因，通过将来自squint过量表达、缺失Nodal信号的MZoep突变体或野生型30%外包期胚胎的RNA与Affymetrix斑马鱼寡核苷酸芯片杂交。
