查询词典 karyon

Immunohistochemical study showed that ER and PR were mainly localized in karyon of epithelial and stroma cell, and also in smooth muscle cell in all specimen. Marked difference of intense staining was observed between implantation site and non-implantation site in the same patient, and the latter is stronger for both ER and PR . There are significant difference between implantation site and non-implantation site for ER expression or PR expression (t=- 3.895, p=0.001; t=- 3.574, p=0.001, respectively).

第一部分输卵管妊娠种植部位、非种植部位和慢性输卵管炎中雌孕激素受体的表达方法：采用免疫组化方法对30例输卵管妊娠患者的种植部位和非种植部位，12例分泌中期慢性炎症输卵管壶腹部ER、PR的定位及半定量研究，并以17例分泌中期正常壶腹部输卵管为对照。

mitochondrial dnais the only inheritant substance except for the nuclear dna in a euˉkaryon cell,which is related to the oxidative phosphorylation of a cell.mitochondrial dna is the important target of carcinogens and is vulnerable because of its structure and function.the mutation of mtdna could reduce the nomal respitation and release large quantities of ros,whichincrease the danger of cancer happening.so,mtdna has been thought to be involved in carcinogenesis and recently more and more studies in this aspect have comeout.in this paˉper,we review the researches for relationship among mtdna mutation and tumors in digestion system,woman system,head and neck,urinary systemand blood system.

线粒体dna（mitochondrial dna，mt dna）是真核细胞中唯一存在的独立于核dna之外的遗传物质，与细胞的氧化磷酸化功能密切相关。mtdna自身的结构和功能特点决定了它是致癌物作用的重要靶点，易受致癌因素的损伤而发生突变。mtdna的突变可削弱正常的呼吸功能，释放高水平的活性氧，进而增加肿瘤发生的危险性，所以mtdna被认为与肿瘤发生有密切关系。近年来，这方面的研究越来越多，本文现就mtdna突变与消化系统肿瘤、妇科肿瘤、头颈部肿瘤、泌尿系统肿瘤等实体瘤以及血液系统恶性肿瘤之间的关系作一简单的综述。

The cytomorphological changes of K562 cells were observed in the electron microscope.Results RRTJ at the concentration of 1μL/mL expressed obviously inhibitory effect on the growth of K562 cells.The inhibitory effect at the concentration of 2μl/ml went up to its highest at 83.4%.RRTJ showed virulence to K562 cells.The karyon changed because of RRTJ attending.

结果 每mL培养液含1μL刺梨汁即对肿瘤细胞增殖有明显的抑制作用，每mL培养液含2μL刺梨汁抑制作用达到最大，为83.4%，再加大剂量抑制作用无明显升高，各种剂量的刺梨汁对细胞均无毒性，刺梨汁的加入使得细胞体积明显变小，细胞核形态发生改变，异染色质增多。

3Rhe distribution and change of proliferating cell nuclear antigen in seminiferous tubule: The positive staining of proliferating cell nuclear antigen was found in slices of all groups, the immunological positive products were located at karyon, usually in brown yellow granules, only a small part of them in diffuse state; the immunological positive cells were mainly the spermospores, besides a small quantity were spermiocyte, supporting the cell and myoid cell nuclear to be stained.

3增殖细胞核抗原在生精小管中的分布及变化：各组切片均可见增殖细胞核抗原阳性染色，免疫阳性产物位于细胞核，通常呈棕黄色颗粒，小部分呈弥散状；免疫阳性细胞主要是精原细胞，另外还有少量初级精母细胞、支持细胞和肌样细胞核着色。

They include cerebellum,cerebral cortex,hypothalamus, mesencephalon, and pons.A few of positive cells could be seen in the medulla oblongata. NADPH-d positive neurons appears blue.Their shapes were diversform such as polygon,fusiform,nummular and oval etc. Karyon hasn't pigmentation. Dendriate and axon's pigmentation are clear.

实验一利用NADPH-d酶组织化学技术，对NOS阳性神经元在兔脑的总体分布规律及其衰老性变化进行了系统研究，结果表明：①NADPH-d阳性神经元分布于兔脑各个部位，几乎涉及所有区域：包括小脑、大脑皮质、丘脑下部、中脑、脑桥和小脑，而延髓分布较少。

Results: The positive unit of survivin expression intensity in trophocyte cytoplasm and karyon was subsequently increased in following order: normal early gestation villi, hydatidiform mole, invasive hydatidiform mole and choriocarcinoma.

结果：survivin在滋养细胞细胞核及细胞浆的表达强度PU值依下列顺序增加：正常早孕组、葡萄胎组、侵蚀性葡萄胎组及绒癌组，各组间的表达强度差异有统计学意义(P.05)。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
