血吸虫

It was not cross- reaction with Entamoeba histolytica and Schistosoma japonica.It is a simply and better method to extract the DNA with lysine boiling.

结果 经扩增于500bp、670bp、1200bp出现特异性片段，与原选择的编码基因片段大小相同，此特异片段与溶组织内阿米巴、日本血吸虫DNA无交叉反应，不同的DNA提取法结果显示：用裂解煮沸法同样可从仅含1条旋毛虫幼虫的25μl正常小鼠血浆中扩增出特异性片段。

Methods Four villages,with different epidemicity of schistosomiasis,were selected as fields, of which every subject was examined with kato-katz, ELISA and IHA techniques simultaneously.

方法选择四个日本血吸虫病流行程度不同的试点村，对5～65岁适检人群进行Kato-Katz法、ELISA法、IHA法等3种方法平行检测。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
