In HeLa cells trasnfected with GFP-BGLF4 expressing plasmids, cells were sorted into two groups with various levels of BGLF4 expression by FACS. We found that these two populations of cells display dramatically different cell cycle profile.

若利用HeLa细胞将GFP-BGLF4转染送入细胞后，对BGLF4表现量多或表现量少的细胞群各别分析其DNA含量，则发现BGLF4表现量高时S-phase细胞明显增加，而且这些细胞的细胞周期将无法离开S-phase往G2/M-phase过渡转换时期推进。

The cortical cells had thin walls and mitochondrium, and nucleus wassurrounded by chloroplasts, and vesicles were next to cell plasmalemma. However, cellwalls of velamen, cortex and exodermis in the mycorrhiza of D. nobile had ring orpapillary thickenings in many cases. The hyphae were surrounded by moremitochondria and vesicles of plant, and the hyphae were digested and their structure waschanged at last. The cell wall of endodermis also had typical ring thickenings, and manysieve orifices in sieve tube elements of phloem were covered by callose, while therewere liaison cords in a few sieve orifices.

Beijingensis under three droughttreatments, normal, moderate and severe stresses. The results showed:(1) the canker disease ofboth cultivars was serious gradually with increased drought;(2) the bark tissue cells sufferedplasmolysis, more evident with the severity of drought stress;(3) under the drought andinoculation with B. dothidea, cells of two cultivars damaged at different degree, mailyrepresented in the changes of organelles, such as chloroplast swollen and distorted, number ofmitochondria increased and membrane system indistinct; then organelles suffered furtherdamagement with inoculation time, thinned mitochondrias stroma, decreased cristae, crumpledand partly broken membrane of chloroplasts with stroma exosmosis. At last, the chloroplastspartly disorganized;(4) the hyphae growed mainly intercellular in resistant cultivar and notonly intercellular but also intracellular in susceptible cultivar, which directly caused thenecrosis of cells;(5) under the severe drought, the damage of cells enhanced the infection ofpathogen and drought and pathogen stressed together and promoted the disease development;the damage from pathogen on cells was more serious than that from drought.

结果显示：(1)随着干旱胁迫程度的增加，2种杨树溃疡病害发生渐趋严重；(2)干旱胁迫下，杨树树皮组织细胞发生质壁分离，并随胁迫程度的增加而严重；(3)干旱胁迫下接种病原菌，2种杨树细胞发生不同程度的损伤，主要表现为细胞器发生较大变化，如出现叶绿体肿胀变形、线粒体数量增多，质膜模糊不清等现象；随接种时间的延长，细胞器受到进一步损伤，叶绿体被膜折皱，严重时局部破裂，基质外渗，并部分最终解体；(4)毛白杨中的菌丝主要在细胞间隙中穿行，而北京杨的菌丝除在细胞间隙中生长之外，侵入细胞内部也较多，直接导致细胞的解体；(5)干旱胁迫下细胞的损伤促进了病原菌的侵染，干旱和病原菌的双重胁迫加剧了病害的发生程度，并且病原菌侵染对细胞的破坏程度大于水分胁迫。

Under optical microscope, the cell of NS arrayed as nest, the nuclear was big, deep-stained, thickened-karyotheca, chromatin granulated, Pathologic karyokinesis can be seen.

DDP组癌巢周围可见少量纤维组织增生、局灶性坏死，并可见炎细胞浸润；LNT组镜下见少量细胞凋亡，凋亡细胞变小，变圆，核固缩，胞浆浓缩，染色加深，凋亡细胞周围未见炎症反应；LNT+DDP组与LNT组镜下大体相同，但可见到较多量的凋亡细胞。

Each group with drug had effect on inhibiting Lewis lung cancer tumor,LNT DDP had the best effect,46.2%,the rate of inhibitory effect of LNT、DDP was 35.6%、39.7%respectively.3.Under optical microscope,the cell of NS arrayed as nest,the nuclear was big,deep-stained,thickened-karyotheca,chromatin granulated,Pathologic karyokinesis can be seen.

Except the incomplete maturation of spermatid nuclear and oocyte activation, idendification of a live spermatid is a pivotal procedure. It is difficult to distinguish round spermatids from other round cells such as spermatocytes, monocytes, polymorphonuclear leukocytes and so on.

除精子细胞的核蛋白不完全成熟及卵子激活不足等因素外，如何正确选择存活精子细胞是个难题，如圆形精子细胞与精母细胞、单核细胞和多形核白细胞等其他圆形细胞的区分就比较困难。

FUNGI Fungi are almost entirely multicellular, heterotrophic (deriving their energy from another organism, whether alive or dead), and usually having some cells with two nuclei multinucleate, as opposed to the more common one, or uninucleate per cell.

FUNGI Fungi是几乎完全地多细胞性，异养(获得他们的能量从另一个有机体，是否活或死)和通常有与二个中坚力量的有些细胞多核，与更加共同一个相对或者单核每个细胞。

We obtained 132 cDNAs including 118 unique genes and fall them into seven categories after analyzed by BLASTX and Go: phytosynthesis (8.7%), protein synthesis (19.1%), cell proliferation and differentiation (22.6%), cell enlargement (5.2%), metabolism(7.8%) and stress response (7.8%).

结果表明，自由态多胺的含量和多胺合成酶基因的表达在果实发育前期较高，并且，多胺在细胞分裂旺盛的外果皮中分布较多，说明多胺主要在黄瓜果实发育的细胞分裂期起作用。

A lot of organelles such as mitochondria, rough endoplasmic reticula and Golgi bodies were observed in fiber cell. Then, double karyotheca disappeared, and the organelles disintegrated. Multivesicular bodies appeared in fiber cytoplasm. With the further development of fiber, fiber wall underwent continual thickening with aging, and polylaminate structure gradually appeared. While the agglutinated nucleus, transfer vesicles, plasma membrane and plasmodesmata still presented.

研究发现，次生壁形成早期，细胞核具有双层核膜，染色质凝聚，可见大量的线粒体、粗面内质网和高尔基体等细胞器存在于纤维细胞中；随后，双层核膜消失，细胞器将逐渐解体，多泡体开始出现在纤维细胞的细胞质；随着年龄的增加，纤维细胞壁逐渐增厚，并出现多层结构现象，而运输小泡、细胞膜、胞间连丝和凝聚的染色质将持续存在。

Since an excessive cell growth is considered as the main pathological event, cell proliferation model occupy most of the animal models, and these cells include retinal pigment epithelial cell, fibroblast cell, cartilage cell and vascular endothelial cell.

由于PVR的主要病理变化是细胞的过度增生，因而动物模型多以细胞增生模型为主，细胞种类有视网膜色素上皮细胞、成纤维细胞、软骨细胞、血管内皮细胞等。

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。
