On the termination date, the cultured explants were all examined by Western blot, HE and transmission electron microscope. Our results showed that after 12-days in culture, the cultivation treated with AS-ODN reduced the synthesis of AMBN and had a deformed dental cusp with thinner enamel matrix. Ultrastructure analyses showed that there was hardly any cisternae of the rough endoplasmic reticulum in the ameloblasts at the tip of the cusp of AS-ODN treatedexplants. However, on average the enamel matrix was thinner compared with that in the control group. Furthermore, the collagen fibers in extracellular matrix were found disorganized. These findings seemed to provide a direct experimental evidence that tended to indicate that the arrested AMBN translation in cultured tooth germs might result in the delay of the tooth development.

经用Western蛋白印迹检测表明，所设计的反义核酸对AMBN InRNA具有良好的封闭效果并成功阻断了牙胚对AMBN的表达；在缺乏AMBN情况下，与对照组相比，实验组牙胚在体外可以继续生长发育至钟状晚期，出现成釉细胞和成牙本质细胞的分化，成釉细胞可以分化成为分泌期型成釉细胞，胞浆中缺少合成蛋白质所必需的粗面内质网和高尔基氏体，缺乏溶酶体，表明对蛋白合成和脚的能力降低；实验组牙胚有牙尖形成和基质分泌，但牙尖形态异常，基质形成减少，牙尖周围基质最厚处为O.6卜m，明显薄于对照组的5.spin，基质中胶原纤维粗细不等，排列稀疏， 3 第四军医大学硕士学位论文未见钙化现象，充分证明了AMBN在牙胚发育中参与釉质基质形成和矿化过程，影响胶原纤维和牙本质基质的合成，促进成釉细胞对蛋白质的合成和釉质基质蛋白降解。

The appearance of NVOCC links up the relation of owners cargo and common carriers,and makes the market of foreign trade transportation activity,decrease the transportation cost in some extent.But in another aspect,NVOCC take part in the whole procedure of transportation,the legal relation of consigners and common carriers was blocked,and this will add risks of the consigners.

无船承运人的出现，沟通了货主和远洋公共承运人之间的联系，活跃了外贸运输市场，在某种程度上降低了中小货主的运输成本，但是，另一方面无船承运人参与整个运输过程，阻断了货主托运人与远洋公共承运人之间的法律联系，可能增加货主托运人的风险。

Setting up the administrative model on HIV/AIDS comprehensive treatment and care in Changsha will play the role of controlling contagions, preventing HIV spread, delaying the course of AIDS disease, depressing the rate of incidence and mortality of HIV/AIDS and enhancing the life quality of HIV/AIDS patients in the capital city of Hunan Province.

该模式的建立，充分、合理地利用了湖南省会长沙市丰富的医疗资源，在管理HIV传染源，延缓HIV/AIDS疾病的进程，降低相关疾病发生率、病死率，降低人均治疗费用，提高HIV/AIDS生活、生命质量以及阻断AIDS的迅速蔓延方面发挥了较好的作用。

Similarly, after microinjection of glucocorticoid or mineralocorticoid into bilateral rVLM with the pretreatment of DKJ-21, the elevation of BP, HR and the pressor response induced by the dPAG stimulation was abolished, which suggested that adrenal corticoids may exert their effects on the incidence of stress-induced hypertension through their modulation onto the muscarinic recptors in the rVLM.

再进一步的实验表明，以DKJ-21预先处理的正常血压大鼠，由双侧rVLM分别微量注射肾上腺糖、盐皮质激素引起的升压、加快心率、以及增强防御性升压反应的效应也能被全部阻断，提示肾上腺皮质激素在rVLM增强心血管活动以及在应激致高血压发病机制中的作用可能是通过对该部位有关心血管神经元细胞膜上M-受体的调节作用而实现的。

Low-dose naltrexone, at higher doses may block the endorphin and enkephalin receptors, about 3 or 4 hours to eliminate from the body - but the elevated concentrations of endorphin and enkephalin One day can be maintained.

低剂量纳曲酮，在较高剂量时可阻断内啡肽和脑啡肽对受体的作用，大约3或4小时内从体内消除--但升高的内啡肽和脑啡肽浓度可维持一天。

An ELISA(enzyme-linked immunosorbent assay.) was developed for detection of bovine brucellosis by using LPS as antigen purified by Heating - phenol recommended by OIE (office international des epizootics).

采用世界动物卫生组织推荐的热酚法提取的脂多糖作为抗原，建立了牛布氏杆菌病的ELISA方法，对45份血清进行检测，证明本ELISA方法灵敏性较高，经阻断试验和交叉试验，证明特异性较好。

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。
