芽细胞

This results seemingly indicate tnat the morphogenic potential of calli and 〓h〓 fo〓mation of abnormal shoots may be related to the degrees of the aber〓ation of chrome〓ome numbers.

Here we show that in budding yeast, the ability of cells to grow changes during the cell cycle. We find that cell growth is faster in cells arrested in anaphase and G1 than in other cell cycle stages.

研究者在芽殖酵母中发现细胞生长能力在细胞周期进程中是变化的，阻滞于后期和G1期的细胞较处于其它周期时相的细胞生长更快。

A rapid, efficient protocol to detect the toxicity of Cu2+ stress using wheat coleoptile, which is simple, uniformal in structure and sensitive, was established. By using this model, the mechanism of Cu2+ stress leading to the inhibition of cell elongation was also studied.

本文以小麦为材料，研究不同浓度Cu2+对小麦种子萌发和幼苗生长的影响及机理；利用小麦胚芽鞘结构简单、反应敏感的特点，探索建立小麦胚芽鞘快速检测铜离子毒害模式，并利用此模式研究了铜离子胁迫对细胞伸长抑制作用的机理。

Most aneurysms specimens showed structure changes, including injury of endothelial cell, disrupture or disappearance of the internal elasticlayer, scarce of contractile fiber cells.

动脉瘤瘤壁中有不同程度的单个核细胞成分的浸润(淋巴细胞或单核/巨噬细胞样细胞)，尤其在"中膜"层或"中膜"与内膜交界处较为明显，同时，在细胞集中区伴有数量不等的新生的营养血管，以上改变类似"肉芽组织"样改变。

Debris necrosis of lymph node is not the specific changes of KD. In the tuberculosis of lymph node,① debris necrosis is obvious, but it tends to be caseous nercrosis;② histiocytes, macrophages and foam cells are hyperplasia in the necrotic area or lymph sinus, moreover, epithelioid cells can be found and they tend to be form granuloma;③ numbers of neutrophils infiltrate in the necrotic area;④ the etiologic assay of acid fast bacterium tuberculosis bacterium is positive;⑤ typical clinical manifestation is insufficient.

淋巴结碎屑性坏死并非KD特有病变，诊断KD需先除外有明显碎屑性坏死的淋巴结结核病，后者主要表现：①碎屑性坏死虽明显，但趋于干酪样坏死；②坏死区内或同时在淋巴窦内，组织细胞、巨噬细胞和泡沫细胞增生，并演变为上皮样细胞和趋于肉芽肿形成；③坏死灶内、外可有数量不等的中性粒细胞浸润；④抗酸杆菌／结核杆菌病原学检测阳性；⑤缺乏KD的典型临床过程。

Results In animal study, lumbricus could inhibit the growth of staphylococci, bacillus coli and bacillus aeruginosus. The time of wound healing in experimental group was 4 days shorter than that in control group. At 4d and 7 day the numbers of the capillary, blood vessel endodermis and desmohemoblast desmocyte and splitting epithelium of trial group were much more than those of control group. At 4d the trial group′s numbers of splitting mesenchymal cell were much more than that of control group. From 3d on the wound healing and granulation filling of experimental group were much quicker than those of control group.

结果 动物实验中，地龙能抑制金黄色葡萄球菌、大肠杆菌及绿脓杆菌的生长；实验组创面愈合时间较对照组提前了4天；第4、7天实验组动物创面的毛细血管数、血管腔内皮细胞数及间质成纤维细胞数均较对照组明显增多，上皮细胞分裂象也高于对照组，第4天的间皮细胞分裂象也高于对照组；自第3天始创面愈合及肉芽充填速度实验组明显快于对照组。

Maximum tolerable dose and lowdose metronomic chemotherapy have opposite effects on the mobilization and viability of circulating endothelial progenitor cells ［J］.

在肿瘤的新生血管形成过程中，内皮细胞起决定性的作用，这些内皮细胞一部分直接来自肿瘤组织内原有血管的内皮细胞的芽生生长，一部分来自于骨髓内的内皮祖细胞的动员和释放［2］。

The list of possible causes of diabetes insipidus in this case and many others is extensive and includes infection (tuberculous pachymeningitis and Whipple's disease), malignant neoplasms (germ-cell tumor and lymphoma), infiltrative processes (hemochromatosis and amyloidosis), autoimmune diseases (Wegener's granulomatosis, lymphocytic infundibulitis, and sarcoidosis), and histiocytosis (Langerhans'-cell histiocytosis and non-Langerhans'-cell histiocytosis).

这例病例其他许多病例尿崩症的可能病因广泛，包括感染(结核性脑脊髓膜炎和Whipple病)，恶性肿瘤，变性疾病，自身免疫病（Wegener肉芽肿，垂体茎淋巴细胞瘤和粒细胞肉瘤）和组织细胞增生症（Langerhans细胞和非Langerhans细胞组织细胞增生症

Varying degrees of thickening in gallbladder wall and straw-colored or brown-yellow plaque or node in cross-section can be seen, some with pedicle swelling like polypus, normal structure of gallbladder wall is found to have bean damadged microscopically, replaced by characteristic yellow granulomatous structure, consisting of plenty of foamy cells, acute and chronic inflammatory cells, fibroblasts, foreign-body giant cells and Touton cells.

大体观察胆囊壁不同程度增厚，切面常见淡黄色大小不等的结节或斑块，有的有蒂呈息肉样隆起。镜下见胆囊壁的正常结构受到破坏，代之以特征性黄色肉芽肿性结构，由大量泡沫样细胞、急慢性炎细胞、纤维母细胞、异物巨细胞及Touton细胞等组成。

In order to confirm this suspect, we choosed a cultured rat granulation tissue fibroblasts model in vitro and applied RT-PCR and cell-ELISA technology to detect the changes of firbroblasts intrinsic EGF, bFGF, TGFβ-1 with their receptors gene expressions and protein synthesises after stimulated by SP. Our purpose was to explore the possible effects and patterns imposed by SP on fibroblasts intrinsic growth factors and their receptors expressions, which maybe offer theoretical basis for promoting wound healing via improving nervous functions and regulating neuropeptides secretions.

为进一步验证这一推测，同时排除在体多因素干扰，我们采用了一种大鼠肉芽组织成纤维细胞体外培养模型，采用RT-PCR与细胞ELISA技术，检测SP刺激成纤维细胞后，成纤维细胞内源性EGF、bFGF、TGFβ-1及其受体基因表达和蛋白合成的改变情况，探讨SP对成纤维细胞内源性生长因子及其受体表达的影响以及方式，以期为经由改善神经功能、调节神经肽分泌途径促进伤口愈合提供理论依据。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
