形态学

METHODS: Benzhydroxamic acid derivative E was artificially synthesized. The gastric cancer line 7901 was selected to serve as the target cell. The effect of medicine E on tumor cell activity was examined by cell culture technology in vitro. The change of morphology and the ultrastructure after treatment with medicine E was observed with the optic microscope and the electron microscope.

以胃癌细胞株7901为靶细胞，采用体外细胞培养技术评价苯异羟肟酸衍生物E对肿瘤细胞活性的影响，通过光学和电子显微镜对E药物作用后细胞形态学进行观察，用免疫组化和RT PCR方法检测细胞凋亡。

The aberrant phenotypes were observed in the anther of tobaccotransformed with ZM401 sense construct: the inflorescence growth and floral axiselongation are suppressed; the flower buds falling or flowers abscission earlier wereobserved. The degradation of tapetum are not observed at the binucleate pollen stagewhich corresponds to the mature stage, although the tapetal cells of untransformedtobacco anther at the same stage have already degenerated completely anddisappeared.

对转基因烟草进行形态学、组织学分析结果表明，ZM401基因以反向方式整合的转基因烟草表现一切正常，而含有ZM401正义基因的转基因烟草在表型和组织学上都出现了异常：花序生长缓慢，花序轴变短，生长过程中花逐渐脱落，花序轴褐化枯死；花药绒毡层退化延迟，药室内壁在雄配子体发育后期不能进行带状加厚，阻碍了花粉粒的释放。

Binucleated granulocytes appear in benign and malignant blood diseases and can substantiate content in morphology. It is helpful for differential diagnosis among some blood diseases.

双核粒细胞在良、恶性血液病症中均可出现，对它进行观察，既有粒系形态学上的意义，又有助于一些血液病的鉴别诊断。

Nuclear cross-sectional area and perimeters were measured morphometrically, and the binucleated cardiomyocytes were counted.

Irritable bowel syndrome is a common functional gastroenteropathy which is the characteristics of abdominal pain/abdominal discomfort and bowel evacuation habit,is short of change of morphology and biochemics.

肠易激综合征是一种常见的以腹痛/腹部不适伴排便习惯改变为特征的功能性肠病，缺乏形态学和生化学改变的生物学标志。

Strain 5#was proven to belong to Pseudomonas genus based on its morphology, biophysiological and biochemical characteristics and the results of the 16S rDNA array analysis.

结合形态学、生理生化特征和16S rDNA序列分析结果，认定5#菌属于假单胞菌属。

Blumea was published in 1934, it is an international journal containing papers on descriptive botany (taxonomy, plant-geography, morphology, and anatomy) of Phanerogams as well as Cryptogams.

该刊创刊于1934年，是国际性期刊，刊载论文内容包括显花植物和隐花植物的描述植物学，即植物分类学、植物地理学、形态学和解剖学范畴。

In this paper,the authors summarize studies on the origin of Boehmeria and advances in the study of genetic relationships of Boehmeria using morphological, chromosomal, isozyme and DNA marker techniques. The authors also put forward the future direction.
