查询词典 cell substance

The results showed that compared with soil culture, the root cap was not obvious with less amyloplast and polysaccharose substance under water culture. The root epidermis under water culture was thinner than that of soil culture, with little root hair or not, in which cortex parenchyma tissue developed with big cell, solution proliferative aerenchyma in intercellular space, and thin cell wall. However, the root cap under soil culture was big, with strong PAS reaction and no aerenchyma tissue.

结果表明：水培后根冠不明显，淀粉体较少，多糖类物质较少而土培根根冠体积较大，淀粉体较多，多糖类物质多，土培根PAS反应强烈；水培根表皮厚度比土培根小，水培根根毛少或退化消失；水培根皮层薄壁组织发达，细胞大型，壁薄，细胞间隙中含有溶生性通气组织，土培根皮层未见通气组织。

In the process of nucleus degeneration, cell organella, for example, rough endoplasmic reticulum, amyloplast, and mitochondrion, maintained normally metabolic functions in cytoplasm, and nutrient substance was still synthesized and accumulated at the time of nuclear degeneration, the starchy endosperm cells carried out their functions until cell death simultaneously.

在核衰退的同时，其胞质中的粗面内质网、淀粉质体和线粒体等细胞器具有正常的代谢功能，细胞仍在合成并积累营养物质，淀粉胚乳细胞表现出一边衰退一边在行使其功能，直到细胞死亡。

The expression profiles analysis of 25 genes belonging to 8 types in different development periods of Y35 somatic embry showed, genes involved in transcription, signal transduction, cell fate, substance transport, cell and development regulation were active at early and middle stages of somatic embryogenesis, while at the stage of cotyledonary embryo maturation, the high level-expressed genes were mainly those related to storage protein, maturation and defense.

通过半定量和Real-Time PCR技术，对WRKY和MAPKK等8类25个差异表达基因在Y35体细胞胚不同发育时期的表达分析显示，转录、信号转导、细胞生长分裂、细胞命运、物质转运和多数发育调节相关基因在体细胞胚胎发生的早期或中期比较活跃，而进入子叶胚成熟后期则主要是储藏蛋白、成熟和防御相关基因大量表达。

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。

AIM: To investigate the inhibitory effects of recombinant human Mullerian inhibiting substance on cell proliferation in human ovarian carcinoma cells (OVCAR8 and SKOV3 cell lines).

目的：探讨重组人苗勒抑制物对人卵巢癌细胞株OVCAR8及SKOV3细胞生长的影响。

The histamine in the particles will increase the transmission capacity of capillary and the velocity of the tissue-fluid flow and the superficial shear stress of related mast cell will be increased, which will once again activate mast cells to discharge active substance. Part of the active substance will be absorbed by capillary and the other part will be passed by tissue fluid to a remote place and it will activate the mast cells and the capillaries there. The directional path of the tissue fluid is approximately the same as the meridian, which forms the phenomenon of feeling-along-meridian on macroscale.

脱颗中的组胺等物质会引起毛细血管壁通透性的增加，进而引起组织液流动速度的增加和肥大细胞表面的切应力加大，这样会进一步促进肥大细胞的激活，从而释放更多的活性物质，这些物质一部分被静脉端毛细血管吸收进入血液，另一部分则随着组织液的定向流动向远处，并进一步刺激远处的毛细血管和肥大细胞，而组织液的定向流动途径和传统的经络线走向基本吻合，在宏观上就构成了循经感传现象。
