They are often morphologically distinct from A chromosomes, being smallerand more highly heterochromatic in most cases. B chromosomes do not pair with Achromosomes, and they are inherited in a non-Mendelian way, exhibiting meiotic andmitotic instability and nondisjunction. However, B chromosome DNA is quiteidentical to the corresponding sequence on the A chromosome complement. So far afew B chromosome specific DNA sequence have been identified. Specific DNAsequences on B chromosome have been the attractive research area on Bchromosomes.

现已在千余种植物和近三百种动物中被发现。B染色体与物种中正常染色体不同：独立于整倍体基因组之外，减数分裂时不与A染色体发生联会和配对，细胞分裂后期不分离，非孟德尔遗传，富含异染色质，不含对宿主主要性状有影响的基因等。B染色体DNA的分子组成既与A染色体极为相似，具有A染色体DNA分子组成的一般特征：富含重复序列和转座成分，染色体三大功能组件DNA高度同源；又与之相区别，含有B染色体特异的DNA序列，这些DNA序列可以为探讨B染色体的起源和进化提供有价值的信息。

In well-differentiated tumors, HSP27 expression was higher than that in normal epithelia.

在低分化的肿瘤细胞中完全不表达，而在高分化的肿瘤细胞染色很深。

It was demonstrated that in the results of both Se-intake and non-Se-intake trained rat muscles, the appearance of unclear cells karyons condensed chromatins karyon's being packed against nuclear membrane and thickening of nuclear membrane changed.

结果发现，无论补硒还是不补硒运动组均有细胞核染色质浓缩及靠近核膜、核膜增厚等典型细胞凋亡的形态结构改变，运动训练可能导致骨骼肌细胞出现凋亡。

RESULTS: Totally 57 rats enrolled in this study, all animals completed Hot pain allergic symptom could not be observed on rats in experimental group during the whole experimental process, but continuously appeared in discharge percentage of nerve fibers at the central end of experimental rat sciatic nerve was remarkably lower than that of the control group 6.79％Sympathetic postganglion nerve fiber budding was not obvious in the slices of entire L4-5 dorsal root neuroganglion of injury side in 6 experimental rats,and basket-shaped cell could not be observed, but sympathetic postganglion nerve fiber budding was obvious in 2 rats in control groups with altogether 41 basket-shaped cells observed.

电生理实验：实验组大鼠坐骨神经中枢端的神经纤维自发放电百分数显著低于对照组(6.79％，46 7％)。③背根神经节切片荧光染色结果：实验组6只大鼠损伤侧L4-5的全部背根神经节切片中看不到明显的交感节后神经纤维芽生，没找到篮状细胞，而在对照组2只大鼠损伤侧L4-5的全部背根神经节切片中可看到明显的交感节后神经纤维芽生，共找到篮状细胞41只。

The periportal red hyaline globules seen here with periodic acid-Schiff stain are characteristic for alpha-1-antitrypsin deficiency (a person with homozygous pi-ZZ genotype) The globules are intrahepatic collections of alpha-1-antitrypsin that is not being excreted from the hepatocytes .

1-抗胰蛋白酶缺乏症可见典型的病理变化是经 PAS 染色，可见肝细胞内有圆形红染半透明的玻璃样小滴。小滴是肝内α1-抗胰蛋白酶聚集不能被肝细胞排泄而形成的。

Methods Constructed the model of fetal scarless wound healing and investigated the expression of collagen in fetal and adult rat wounds by immunohistochemistry and in situ hybridization.

染色，Ⅰ、Ⅲ型胶原免疫组化，Ⅰ、Ⅲ型胶原原位杂交。结果胎鼠伤口愈合快，组织结构再生完全，没有瘢痕形成，胶原呈网状正常排列，Ⅰ、Ⅲ型胶原蛋白及表达均增多，同时伴细胞数增多，Ⅲ型胶原首先形成网状排列；成年伤口胶原纤维沉积慢，平行排列的胶原逐渐呈束状填塞伤口以致瘢痕形成，伤口内Ⅰ、Ⅲ型前胶原mRNA表达均增多，细胞数目增多不明显。

The varying of expression of Cfos in different phases and different brain tissue including caudate nucleus, putamen, globus pallidus, hippocampus, nuclei ventrolaterales thalami, parvocellular reticular nucleus, and dorso lateral magnocellular nucleus were examined by immunohistochemical technique.

采用Cfos免疫组化染色，在显微镜下观察Cfos于不同时相在脑膜、脑皮质区及相关核团如尾壳核、苍白球、海马、背侧丘脑腹后外侧核、小细胞网状核、背侧旁巨细胞核的阳性细胞数。

The dysplastic cells in the center extending to upper right are smaller overall with darker, more irregular nuclei.

从中央到右上方为不典型性增生的细胞，细胞的体积小，染色深，细胞核不规则。

Results: From the second days of the operation, the brain swellen overtly. RBC and phagocyte can be seen in the cerebral interstitial space. The adventitia of the brain arteries and the perivascular Virchow￣Robin space dilated irregularly. The neuronal number of hippocampal CAI sector decreased evidently. In some neuron both the nucleus and cytoplasm condensed, chromatin gathered near the nuclear membrane.

结果： 自术后第二天可见脑组织水肿，红细胞溢出及吞噬细胞浸润，小血管壁外膜及Virchow￣Robin间隙增宽，内含大量水肿液，海马CAI区正常神经元数量明显下降，且排列及不整齐，细胞皱缩，核固缩、深染，核染色质聚集，核周囊膨大，胶质细胞增生。

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。
