查询词典 TK

We won ' t go over the Tk widgets in detail as there is plenty of good docu- mentation available on them, either from the Tkinter topics page at the main Python Web site or the abundant number of Tcl/Tk printed and online resources (some of which are available in Appendix B).

我们不准备对所有Tk组件一一详细讲解，因为已经有许多关于它们的很好的文章可供参考--不论是从Python网站的Tkinter主题页面还是数量可观的Tcl/Tk印刷品，抑或是在线资源（其中一些可以在附录B中找到）。

Methods Eight-four rats were randomly divided into 7 groups. PDR2/TK or buffer TE was injected through the artery/portal vein of the left live lobe. Ganciclovir or normal saline was injected intraperitoneally.

84只大鼠随机分为动脉TK、动脉TK+更昔洛韦、动脉对照、门静脉TK、门静脉TK+GCV、门静脉对照及空白对照等7组。

The thymidine kinase gene of infectious laryngotracheitis virus Beijing E2 strain was amplified by PCR, cloned into pGEM-T vector, and sequenced. Sequence analyses showed that the TK gene was very closed among sequenced ILTV strains.

以纯化的传染性喉气管炎病毒北京E2株基因组DNA为模板，通过PCR方法扩增了ILTV北京E2株的完整TK基因，将其克隆到pGEM-T载体上，并测定了序列，与其它ILTV毒株TK基因比较说明，ILTV不同毒株的TK基因高度保守。

Although a few TK genes have been shown to be mutationally altered in specific human cancers (1), it is not known how many or how often members of the TK gene family are altered in any particular cancer type.

尽管有少数TK基因被报道在特定的人类肿瘤中有突变，但对整个TK基因家族中有多少个基因多少次在某一特定肿瘤类型中有突变，还是个未知数。

Methods: The human KDR promoter (-225 bp~+127 bp) was cloned by PCR. Subsequently, a recombinant adenoviral plasmid carrying KDR promoter for the HSV-tk gene was constructed with the AdEasy system. As a control, the plasmid pAdCMV-tk carrying CMV promoter for the HSV-tk gene was also constructed. 293 packaging cells were transfected by both newly-constructed plasmids and the infectious viruses AdKDR-tk and AdCMV-tk were generated. Then the KDR-producing cells and the KDR nonproducing cells (HepG2) were infected with AdKDR-tkand AdCMV-tk, followed by ganciclovir administration.

应用PCR克隆出人KDR基因启动子序列－225bp~+127bp，以AdEasy system为载体，构建携带受KDR启动子或CMV启动子调控tk基因表达的2种重组腺病毒质粒pAdKDR-tk和pAdCMV-tk，在293细胞中包装、扩增后，体外感染表达KDR的脐静脉血管内皮细胞系HUVEC和不表达KDR的肝癌细胞系HepG2，并给予不同浓度的丙氧鸟苷处理，5d后收集存活细胞并计数。

If GVHD occurred, GCV would be administered in order to kill TK〓T lymphocytes selectedly and to control GVHD, while preserving therapeutic effects of T lymphocytes.

将TK基因体外转染供者T细胞成为TK〓T细胞，然后和CD34〓细胞混合移植，一旦发生GVHD，则给予特异性药物丙氧鸟苷治疗，选择性杀死引起GVHD的TK〓T细胞，使GVHD得到控制，同时又可保留T细胞的治疗作用。

The thymidine kinas gene was cloned from human herpes simplex virus Ⅱ by PCR techniques; eukaryon expressing vector pcDNA3/tk and pcDNA3/angio/tk fusion gene was constructed by DNA recombination; The treating effects of human primary liver cancer strain SMMC-7721 in vitro and nude mouse model transplanted with human liver cancer in vivo are studied.

通过PCR技术，由人单纯疱疹病毒DNA克隆获得单纯疱疹病毒Ⅱ型胸苷激酶基因；通过基因工程技术，构建真核表达质粒pcDNA3/tk及融合基因真核表达质粒pcDNA3/angio/tk；研究其对人原发性肝癌SMMC-7721细胞株的体外杀伤作用及对人原发性肝癌裸小鼠移植瘤模型的治疗作用。

Results The recombinant plasmid pSNAV2.0-TK was verified byPCR and restricton endonuclease. The coat protein of AAV was detectedby SDS-PAGE method, the purity of rAAV2/HSV-TK was＞98% byHPLC method and the titre of rAAV2/HSV-TK was 1×10~(12)v.g./ml byDNA dot blot hybridization.

结果：重组质粒pSNAV2.0-TK PCR扩增的片段大小和酶切鉴定所切下的片段与预计结果一致；SDS-PAGE法检测到三条特征性的AAV外壳蛋白条带，HPLC法检测rAAV2／HSV-TK的纯度＞98％；用DNA斑点杂交方法检测rAAV2／HSV-TK的滴度为1×10~(12)v.g。
