Prepare 131I-labbelled anti-CD20 monoclonal antibody using lodogen iodine labelling;(2)Measure the immunity activation of labbelled antibody by means of both cell combine analysis and LDH cytotoxicity detection kit;(3)Evaluate the injury rate of tumor exposed to 131I-chimeric anti-CD20 monoclonal antibody in vitro. The MTT method and the experiment of cell growth control are used;(4)Record the apotosis of Daudi cell using gelose electrophoresis;(5)Learn the inhibition effect of radioactive medication on the marrow. Radiohnmunoimages are taken on various intervals after injection of the labeled antibodies to the nude mice. The distribution of radioactive medication, I31l-labeled antibodies, in the marrow tissue indicates the inhibition effect. Here a B cell non-hodgkin lymphoma model in nude mice is established by us;(6)28-day observation are done in 3 groups of nude mice model.

PartⅠ/chapter 3 The viability of cultured cerebral endothelial cells was determined by measuring the release of intracellular enzyme lactate dehydrogenase by nonviable cells with increased permeability.

第一部分第三章乳酸脱氢酶（1actate dehydrogenase，LDH）是一种细胞内酶，当细胞失去活力膜通透性增加时即释放到细胞外。本文通过测定释放到培养液中的LDH的量来测定牛脑微血管内皮细胞的活力。

The codA gene encodes cytosine deaminase, which can deaminate nontoxic compound 5-fluorocytosine (5-FC) to the highly cytotoxic compound 5-fluorouracil (5-FU). 5-FU can influence the cells survival through interference with the synthesis metabolism of the RNA and DNA.

codA基因在细菌体内编码胞嘧啶脱氨酶，CD能把对细胞无毒的5-氟胞嘧啶(5-FC)脱氨成为有毒的5-氟尿嘧啶(5-FU)。5-FU通过干扰RNA和DNA的合成代谢从而影响细胞的生存。

Young thalluscells of low development are easy to dedifferentiate and grow intoseedings directly,while mature thallus cells have to releasemonospores to form seedings through a stage of multicellular groupfor dedifferentiation.Old thallus,mainly of productive cells,releasecarporspores to form conchocelis at last.

幼嫩的叶状体细胞，由于其分化程度低，易于脱分化而直接长成细胞苗；成熟的叶状体细胞，要经过多细胞团这样一个脱分化的阶段，然后放散单孢子成苗；而老叶状体以生殖细胞为主，只能放散果孢子，最终长成丝状体。

The hydroxamic acid compounds can also inhibit histone deacetylase and are suitable for use in selectively inducing terminal differentiation, and arresting cell growth and/or apoptosis of neoplastic cells, thereby inhibiting proliferation of such cells.

所述的异羟肟酸化合物还可以抑制组蛋白脱乙酰基酶并且适合于选择性地诱导终末分化，以及阻止赘生性细胞的细胞生长和/或细胞程序死亡，由此抑制这些细胞的增殖。

In addition, under the above-selected nitrosification condition, the immobilized cells N4 and B08 were used for the combined short-cut biodenitriflcation with the ratio of immobilized cells 1:1 and the seed volume 15%, 27h the denitrogenation efficiency reached 97.53%; the immobilized cells N4 and B08 were used to do denitrogenation application test on eutrophic lake water of our school, 12h the NH4+-N removal rate was 84.06%.

在以上所选亚硝化条件下，按1：1的比例，亚硝化细菌N_4和反硝化细菌B_(08)固定化细胞接种量为15％，广西大学硕士学位论文固定化微生物捷径生物脱氮的研究作联合捷径脱氮试验，27h脱氮率为97.53%；并作本校富营养化湖水的脱氮应用试验，处理12h，NH4十一N去除率为84.06%。

Tissue engineering cornea stromata were constructed in vitro.

用去垢剂联合酶的方法脱细胞处理猪角膜基质，在去细胞猪角膜基质材料上接种体外培养的兔角膜基质细胞，并将兔角膜基质细胞进行PKH26荧光标记，在体外构建组织工程角膜基质。

PURPOSE: To develop submandibular gland acellular matrix and observe its structure and analyze its histological ingredients.

目的：制备天然的下颌下腺脱细胞基质材料，观察脱细胞后下颌下腺的组织结构，并对其成分进行分析。

Combined use of trypsin, hypertonic solution and chemical detergent is a better method to prepare acellular vascular matrix, and the vascular matrix be wellpreserved in liquid nitrogen.

液氮保存后1、2、3月扫描电镜观察与新鲜标本无明显差别。结论酶、低渗溶液、化学除垢剂联合法是制备脱细胞血管基质的较好方法，制得的脱细胞血管基质可放入液氮中保存。

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。
