无孢子生殖：配子体的发育直接来自孢子体的细胞而不经过减数分裂和孢子产生的生殖过程。

In addition, the mitochondria showed no signs of swelling and the nuclear membrane remains intact. Multiple membrane-bound apoptotic bodies and engulfment of cell debris and corpses by phagocytes were observed at 24h, while extensive cell loss appeared at 48h. These results demonstrated the occurrence of high level of apoptosis by 24h postdosing.

相应的超薄切片在电子显微镜下得到结果与光镜下一致，24h前线粒体形态结构无明显变化，主要有染色质浓缩、边集及分割，以及内质网空泡化和凋亡小体的形成；24h后可观察到线粒体的肿胀和扩张，细胞发生崩解和死亡。

The results indicate that the larger the concentration of chitosan in the capsules is the slower the release rate of capsule. The biocompatibility tests of the three heparin microcapcules/PLA composite materials show that all materials are negative and have no obvious toxicity. There is no potential hypersusceptibility substance in materials, and the content of pyrogen is conforming to the requirement of organisms.

"扎矮76"的形态解剖特征与普通山定子和杂交后代中普通型植株对比，"扎矮76"和其它携带Dw主基因植株的：春梢短59.6-66.2％，梢长与梢粗比值小33.2-58.4％，节间短14.0-42.7％，春梢节数少40.7％，杂种苗下胚轴短65.0％，春梢叶柄形指数小34.5-50.2％，叶柄短25.2-45.7％，春秋梢交界处有瘤状突起，叶缘波状，萼片肥厚有刺状突起，萼部缢痕不明显，脱萼后萼痕较大、萼洼平或高于果面；新梢生长点宽而短，在距顶端1.0gmm处有较多体积较大、内容物较少、细胞核小或无的待化细胞。

NSCs existed in the occipital of cortex of different fetal age included middling round cells, NSCs had enations from 0 to 1. Nucli were larger than plasm. Each NSC had nucleoli from 2-4 and rarefaction chromatin. Most of NSCs distributed in three growth modes including crowd, cluster and clone, occasionally with a single growth mode among other nerve ceils.

NSCs呈明显的区域性分布，大部分NSCs以群状、簇状或数个细胞形成的小集落样生长方式存在，少数NSCs以单个形式存在于其他神经细胞中，各胎龄组NSCs在分布、形态、种类、生长方式等方面无明显差异。

SER lacks polysomes; it is active in the synthesis of fats and steroids and in the oxidation of toxic substances in the cell.

cell。光滑内质网上无核糖体，主要作用是脂肪和类固醇的合成以及细胞内有毒物质的氧化。

The method of centrifuge tube culture can be used as a constructing technique of tissue engineered cartilage without scaffold material.

结论在无支架材料条件下，采用离心管培养技术培养的人胚胎关节表面软骨细胞可以构建组织工程化关节软骨，而且接近正常关节软骨的形态和功能。

The mice in experimental group and control group were exposed to 350 cGy radiation produced by 60Co. After 3 h, karyocytes at different concentrations in the fresh human umbilical cord blood were injected into the mice in experimental group A, B, C via their tail veins, and the equal volume of normal sodium was also injected into control group via tail veins. After one month, carbon tetrachloride (CCl4) was injected into experimental group A, B and control group via abdominal cavity, and the equal volume of normal sodium was injected into experimental group C. After two months, immunohistochemistry and reverse transcriptase polymerase chain reaction were used to detect the expressions of human cytokeratin-18 (CK18), cytokeratin-19 (CK19) and albumin in liver tissues of all mice.

采用60Co治疗仪γ射线对实验组和对照组行350cGy的亚致死剂量照射，实验组A、B、C3组照射后3h内经尾静脉分别输入1.0×10^7个/只、2.0×10^7个/只和3.0×l0^7个/只人新鲜脐血有核细胞，对照组经尾静脉注入等体积无菌生理盐水。1个月后对实验A、B组和对照组裸鼠经腹膜腔注射四氯化碳(CCl4)，实验C组注射等体积生理盐水。2个月后采用免疫组化和RT-PCR方法检测裸鼠肝组织人源性CK18、CK19和人源性白蛋白的表达。

我们发现不同临床分期和不同病理分级间CD44v6的表达无明显差异，与Carbognani等［9］对非小细胞肺癌的研究结果相似。

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.
