查询词典 nodules

Results: The study showed that the earliest stromal nodules were fibrous, and with the dual differentiation of myofibroblasts toward both smooth muscle cells and fibrous cells, they developed into fibromyomatous nodules and muscular nodules. The results of reclassifying the 55 nodules immunohistochemically were that 23(42%) was fibrous, 28(51%) fibromuscular nodules and 4(7%) muscular.

结果：结合HE切片和免疫组化结果发现前列腺间质结节的早期为幼稚的纤维性结节，随着结节内肌纤维母细胞向平滑肌细胞和纤维细胞的双向分化，间质结节可继续演化为纤维肌性结节和肌性结节。55个结节按免疫组化分类，纤维性结节占42%，纤维肌性结节占51%，肌性结节占7%。

The results suggested that the fibrous nodules of BPH evolved fibromuscular or muscular nodules with the differentiation of myofibroblast cells within the nodules, and these results were helpful to understand the pathogenesis and development of BPH nodules.

前列腺早期的纤维性结节随着肌纤维母细胞向平滑肌和纤维细胞的分化而演化为纤维肌性结节和肌性结节，明确这种演化过程可进而认识前列腺增生的病理学分类。

RESULTS: On day 2 after PH, oval cells began to proliferate around the portal area, and matrilin-2 deposition was observed in the hepatic sinusoids in the periportal area. On day 9, proliferating oval cells were present in the hepatic acini, and matrilin-2 upregulation was noted. On day 12, as oval cells differentiated to form hepatocellular nodules, matrilin-2 was distributed mainly in the periphery of the nodules, and little protein was present in the nodules.

结果： 肝脏部分切除术(partial hepatectomy， PH)后第2天，卵圆细胞开始向门静脉周围区域增殖， Matrilin-2主要出现在门静脉周围的肝窦状隙内；术后第9天，卵圆细胞进一步向肝实质内增殖， Matrilin-2表达增加；术后第12天，随着卵圆细胞分化为小肝细胞结节，大多数Matrilin-2位于结节周边，少数出现在结节内。

However, the nodule could be induced by germfree liquid that filtered from the rhizobia, cultural medium. It is proposed that the some soluble substances excreted by the cultured rhizobia, can stimulate the plant to form the root nodules. Nevertheless, the nodules formed by this way can't produce haemachrome. So the nodules show light green or white. And there are starch in them.

但根瘤的形成还可由培养根瘤菌的无菌滤液诱导形成，这充分说明根瘤菌生长过程中分泌的某种可溶性物质具有刺激植物形成根瘤的作用，但这种根瘤由于不能形成豆血红蛋白而呈淡绿色或白色，且根瘤中有大量淀粉积累。

To better understand the roles of LsrA protein in nodulation, a series of analyses of nodules using scanning electron microscopy, genetic and biochemical approaches have been carried out. Our analyses suggest that the lsrA1 nodules contain bacteroids in the invasion and establishing zone only. The lsrA gene expression is active early in the invasion zone and activated later than bacA genes. The lost of LsrA protein dramatically reduced the expression of nifA and fixK, and completely blocked the expression of the nifH gene for nitrogenase. LsrA protein functions early in the bacteroid development and it is essential for the development nitrogen fixing bacteroids.

前期的工作中，苜蓿中华根瘤菌Rm1021中90个候选LysR基因已经被定向插入突变，并筛选在自生生长时期、共生生长时期的表型，以期寻找更多在自生状态或共生固氮中有功能的LysR转录因子。1 针对前期鉴定出的共生固氮必需的lsrA基因，我们应用了一系列扫描电子显微镜技术、生物化学、分子遗传学等方法，发现lsrA基因主要在根瘤侵染区开始表达，表达时序也在侵染阶段左右，但晚于bacA基因表达；LsrA蛋白缺失后根瘤固氮区中缺乏具有固氮能力的类菌体，nifA和fixK基因的转录水平降低，nifH基因的转录被完全阻断，因此LsrA蛋白为根瘤发育所必需，是新的根瘤发育信号传导途径成员。2 通过表型筛选我们鉴定了苜蓿中华根瘤菌的oxyR基因，并研究了它的调节特性。oxyR突变后，苜蓿中华根瘤菌对过氧化氢敏感性提高，适应性降低。
