The mice were sacrificed on 7, 10, 14, 21 and 28 days post-inoculation and then the hearts were aseptically removed. Pathological changes in the myocardium were observed by light microscopy and the expression of the CD4+ T lymphocyte in the myocardium was determined by immunohistochemistry. ResultsThe CD4+ T lymphocyte was found in the myocardium in the CVB3 infection group.

It is to say that after amplificated a few autogenetic cells in vitro,we can make cell-scaffold complex when mix these cells with scaffold which has cytocompatibility and biodegradability.

同时，这种细胞—支架复合物无免疫原性，且拥有和自体组织类似的结构和功能，因此被认为具有广泛的应用前景。

The McAb titers of three hybridoma cells lines from ascetic fluid were 1∶6000, 1∶6000 and 1∶12000 by ELISA test respectively. The sensitivity of the McAbs was 102-103 cfu. The McAbs did not have cross-reactivity with any other bacteroides and clostridia.

结果：建立了3株稳定的杂交瘤细胞株，ELISA法测定腹水McAb效价分别为1∶6000，1∶6000和1∶12000，敏感性为102-103 cfu，与其它杆菌、梭菌无交叉反应，竞争抑制试验表明3株McAb作用于细胞表面不同的抗原决定簇。

The mechanic properties of the acellular matrix were evaluated, and the components were analyzed biochemically.

脱细胞后的牛心包组织的厚度、抗拉负荷、抗拉强度、断裂伸长率和热皱缩温度无明显变化。

We have measured the serum levels of total cholic acid in 103 samples of obstructive jaundiced patients and 83 samples of gallbladder stone patients without jaundice by enzymeconjugated colorimetric analysis method.

采用酶偶联比色法测定47例（103例次）阻塞性黄疸和53例（83例次）无黄疸单纯胆囊结石患者血清总胆酸的水平，并探讨其与黄疸程度及肝细胞损害的关系。

Results The expression of CD69 started to express within 2 hours of stimulation and reached its clima x 6～8 hours later.

结果 ConA刺激后2h CD69即有明显表达，6～8h达到峰值；CD8－与CD8＋T细胞相比无明显差异；体外条件对CD69的表达有显著的影响。

HIFU has a confirmative killing effect on human uterine leiomyomas and may become a promising new approach for its non-invasive therapy.

HIFU对在体人子宫平滑肌瘤细胞具有肯定的杀灭作用，可能成为未来子宫平滑肌瘤无创性治疗的新技术。

Endometrial cytopathologic test has clinical value in detecting endometrical lesion by ESDC, and it is simple, safe, reliable, no cross infection and high diagnosis coincidence.

子宫内膜细胞采集器是一种简单、安全、可靠的子宫内膜病变筛查方法，具有痛苦小、出血少、器具一次性使用无交叉感染、诊断符合率较高的优点。

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.
