Methods ELISA was used to detect the specific IgG and IgG 4 antibodies in sera from the patients with clonorchiasis and other parasitic diseases and from healthy persons. Results The sensitivity and specificity of IgG 4 antibodies detected by ELISA in sera from the patients with clonorchiasis showed no significant difference with that of IgG detected.

1。胆囊结石、乙肝病毒感染、血吸虫感染和多产妇是胆囊癌的高危因素；γ-GT可能是胆囊癌有潜力的肿瘤标志物。

Methods The coding gene of Sj32KD antigen was amplified from the cDNA library of the adult parasite by PCR and cloned into the prokaryotic expression vector pET28a to construct a re- combinant plasmid Sj32-pET28a.

应用PCR方法克隆Sj32KD抗原基因，并在大肠杆菌系统中进行表达，利用His亲和层析方法纯化融合蛋白，并应用重组的Sj32KD抗原检测羊日本血吸虫病。

The model integrated site-speific factors and was calibrated to field epidemiological data from 3 subset villages.The dichotomic method was then used to predict different control measures.

利用蒙特卡罗模拟对模型进行模拟，采用二分法用3个村的数据来效验模型，并用经效验的模型来分析在3种控制策略下本地血吸虫病传播的趋势。

The Lake area in Jianghan Plain is one of the most ecotypically fragile areas in Yangtse Valley, and here there are four main ecological problems: frequent flood, silt and sand that make the lake become a swamp, water pollution and eutrophication, and the schistosome.

江汉平原湖区是长江流域生态环境最脆弱的地区之一，洪涝灾害严重、泥沙淤积和沼泽化现象普遍、湖泊水体污染与富营养化问题突出、血吸虫未得到根治等是该区目前存在的主要生态环境问题。

Adult Cyclops, with body length of one to several millimeters, may be caught by naked eye to bring consumers unsanitary sense and may become disease transmission medium as the host of pathogenic parasite, like schistosome and eelworm, to threaten human health. So Cyclops needed be effectively removed to ensure drinking water security.

剑水蚤类浮游动物在用户水中出现，不仅违反了生活饮用水卫生标准中对感官性状指标的规定，给用户带来了不良的感官影响（剑水蚤体长可达1～几个mm，肉眼可见），容易引起用户对水质信心的下降与恐慌，更为重要的是大多数剑水蚤是诸如血吸虫、线虫等水中致病生物的中间宿主，从而成为传播疾病的一个重要媒介，给人们的用水安全问题带来了很大的威胁。

Etiologically, the commom cancerogens include: lowered power of resistance, weakened functions of spleen and stomach, emotional disturbance such as grief, worry and anger, long term mechanical and inflammatory irritation, granuloma caused by the accumulation of schistosome ova, malignant change of polyp from chronic adenoma, chronic ulcer and anal fistula.

根据病因学，普通致癌物包括：低功率电阻，脾胃功能减弱，情绪困扰如悲伤、焦虑和愤怒，长期力学和炎症刺激，血吸虫卵积聚引起的肉芽肿，慢性腺瘤中息肉的恶性变化，慢性溃疡和肛瘘。

Results Beta-tubulin genes, 1439bp and coding for 443 amino acids, was acquired and was submitted to GenBank and to get an accession number that was AY220457. The beta-tubulin gene of S. japonicum and Fasciola hepatica were homologous with an identity of 79%.

结果 获得了1个日本血吸虫新基因－微管蛋白基因，全长1439bp，编码443个氨基酸，与肝片形吸虫微管蛋白基因具有79%的同源性。

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。
