The studies on the capacities of immune responses of lymphocytes in peripheral blood and immune organs of Grass Carp (Ctenpharyngoden idellus Cuvier et Valencinnes) to PHA and SPA with incorporation of 〓H-TdR and active reaction of Acid α-Naphthyl Acetate Esterase indicated that there were T and B lymphocytes in peripheral blood of grass carp, but only T lymphocyte and no B lymphocyte in the thymus of grass carp. It was justified that the T lymphocytes in peripheral blood was originated from the thymus, and B lymphocyte could be from the spleen and anterior kidney of grass carp.

运用〓H-TdR掺入法和酸性醋酸萘酯酶活性检测法分别研究了草鱼外周血以及免疫器官中的淋巴细胞对PHA和SPA的免疫应答以及化学标志特征，发现草鱼外周血中存在着类似于哺乳动物的T、B两类不同的淋巴细胞亚群；同时也发现胸腺中只有T淋巴细胞，而无B淋巴细胞，提示了胸腺中淋巴细胞可能是外周血中T细胞的来源，而B淋巴细胞可能来自脾脏或前肾。

One group was cultured in DEME free of serum; the other in DEME with 10 μg/ml lipopolysaccharides for 6 hours. NF-κB was studied by flow cytometry technique using immunofluorescent staining, and by gel shift assay using γ-32P labeled NF-κB oligonucleotide probe.

取体外培养的第2或3代人角膜基质细胞，同步化后分为2组：无血清的DMEM液培养的不加药组；含质量浓度为10 μg/ml脂多糖的DMEM液培养6小时的加药组。

Gracilis were applied to investigate the effect of proplastid on adaptability, in which such structure was found to be important to the competitiveness during heterotrophic growth in the dark; 2 a new procedure for differential display technology was developed and used to study the influence of plastid on nuclear gene expression, with which it was shown that the loss of plastid could cause remarkable changes in expression of certain nuclear genes.

本文主要有两点突出之处：1）应用裸藻褪色突变株与野生型的生长竞争实验探讨了原质体对于裸藻的适应意义，发现在黑暗环境和异养生长条件下原质体对于细胞的生存竞争有重要作用；2）改进了一种差异显示技术并利用该技术来研究质体的有无对基因表达的影响，证明质体丢失可导致某些核基因表达的显著变化。

The size and localization of oil cells in the leaves, combined with the thickness of leaves, the number of layer of palisade tissue, the ratio of the thickness of palisade tissue to that of spongy tissue, the hypoderm, and the type of hairs, may be used as the identification characteristics of the generas, and even species.

木兰科植物油细胞的分布及其大小与叶厚、栅栏组织层数、栅栏组织与海绵组织厚度间的比值以及下皮层的有无、表皮毛的类型、叶脉的结构等特征相结合，可作为该科中属、甚至种的鉴别特征。

Although clear, the beer is not sterile and a few viable yeast cells and low levels of fermentable sugars remain in the product.

啤酒看上去是清澈透明的，但它却并非是无菌的，其中仍然存在着一些可以存活的酵母菌细胞和少量的可发酵的糖类。

Although clear, the beer is not sterile and a few viable yeast cells and low levels of fermentable sugars rema in in the product.

啤酒看上去是清澈透明的，但它却并非是无菌的，其中仍然存在着一些可以存活的酵母菌细胞和少量的可发酵的糖类。

Acute leukemia is a rapidly progressing disease that leads to the accumulation of immature, functionless cells in the marrow and blood. The marrow often can no longer produce enough normal red blood cells, white blood cells and platelets, leading to anemia and impairing the body's ability to fight infections.

白血病和淋巴瘤协会急性白血病是一种导致不成熟的无功能的细胞在骨髓和血液中聚集的快速进展的疾病，骨髓不能产生足够量正常水平的红细胞，白细胞和血小板，导致贫血和机体抗感染能力下降。

There were location and morphous changing of megakaryocytes in all PV、ET and IMF patients;the incidence rate of JAK2V617F in PV、ETand IMF patients were 80%、26.7%、50% respectively;the mean of leucocytes in patients with JAK2V617F was higher than patiens without JAK2V617F, different stages of reticulin had no impact on the leucocytes in PV and ET patients who were dignosed in the first time.

PV、ET、IMF患者骨髓切片中均有巨核细胞的形态以及定位变化，PV， ET、IMF患者中JAK2V617F的发生率分别为80%、26.7%、50%；有突变患者的白细胞数均值高于无突变患者，初诊的PV、ET患者骨髓中不同纤维增生程度患者的白细胞均值无差别。

A virus is a unit of infectious genetic material smaller than any bacteria and embodying properties placing it on the borderline between life and non-life. The vast majority of the virus capsid protein assembled into icosahedral symmetry of the structure. Caspar-Klug Theory has become a fundamental concept for the classification of icosahedral viral capsids based on the principle of quasi-equivalence.

二：病毒是比任何细菌都小的感染性遗传物质，介于生命与非生命之间的一类无细胞结构的生物，绝大多数病毒的衣壳蛋白装配成二十面体对称的结构，&准等价&原理是解决严格遵从二十面体对称性的病毒衣壳几何特征的有效而成熟的方法。

Under electron microscope at 8 and 12 weeks, there were mature transparent cartilages in the repaired tissues, and there were irregularly arranged slight, even and non-periodical collagen Ⅱ in surrounding.

电镜下：8，12周，修复组织中可见多数成熟的透明软骨细胞及其周围排列不规则的、纤细的、均匀的和无周期性的Ⅱ型胶原。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
