The inflammation reaction hyperplactic stage and lymphatic nodular stage are of nonspecific morphological changes and should be diagnosed with the help of positive tuberculin test and obvious increase of adenosine deaninase ; tuberculous nodular stage has a great number of epithelioid cells,and Langhans cells, caseous necrosis stage is characterized by a great deal of necrotic tissue and debris,a small number of fragmented epithelioid cells

炎性增殖反应期非特异性形态学变化，需要结合结核抗体阳性和腺苷酸脱氨酶明显增高有助于诊断，结核结节期主要可有较多类上皮样细胞及郎罕氏细胞；而干酪样脓样坏死主要见大量坏死组织及碎屑、少数残碎不全类上皮样细胞，此期主要能查到抗酸菌为特点；纤维增殖期，抽出物难取，仅见少数纤维组织、纤维细胞和黏液间质为其特征，提示结核恢复、瘢痕形成所致。

At each time point, we observed morphological changes, in situ detected DNA breaks, and observed expression changes of production of lEGs c-Fos and DNA repair enzyme APE/Ref-1 which participated in many kinds of DNA repairs. Results in the experiment were shown as follow:DHE stain indicates: The model of rat MCAO/R was credible, and the damaged regions included cortex (lobus frontalis, lobus arietalis, lobus occipitalis et al and caudatum.

本次实验采用大鼠大脑中动脉阻塞再灌注模型，将健康雄性SD大鼠随机分为正常组、假手术组和MCAO2h再灌注2h、6h、12h、24h、48h、72h组，观察各时间点损伤区域神经元和细胞的形态学变化，原位检测DNA断裂损伤，检测DNA修复酶APE/Ref-1表达变化情况以及IEGs产物c-Fos表达变化情况。

Methods: NCI - N87 cells were treated by matrine in different concentrations and variablc durations. Ceil growth and proliferation were observed by CCK - 8 assay.

方法NCI—N87细胞经不同浓度苦参碱处理后，采用CCK-8法检测药物对肿瘤细胞的抑制作用，观察细胞形态学改变，检测细胞DNA分布。

Endophytic fungus of strain 2B isolated from Celastrus angulatus has been studied on the taxonomy,agricultural bioactivities, isolation and identification of active components, breeding of high yield strains,and optimization of fermentation conditions in this paper.

本论文以一株编号为 2B 的苦皮藤内生真菌为出发菌株，应用形态学的方法鉴定了其种属地位；研究了其代谢产物的农用生物活性，并对目标活性物质进行分离和结构解析，采取诱变育种手段选育了高产菌株，并对高产菌株的发酵条件进行了优化。

The hemolysin consists three components,B,L1,and L2(35.36.and 45kDa,respeotively),combinations of all three moieties produed the unique ring-shaped zone of hemolysis,increased rabbit vascuolar permeability,caused fluid accumulation in rabbit ileum loop and appeared cellulotoxic reaction on Vero cells.

溶血素由B、L1和L2 3种成份组成，分子量分别为35、36和45kDa 3种成份的协同作用在血琼脂上引起靶状溶血，使兔皮肤血管通透性增加，兔小肠肠段结扎产生积液反应，Vero细胞形态学改变。

These results indicate that sperm washing by centrifugate in morphology analyses has impact on SDI and TZI.

精子形态学分析中离心精液对精子畸形指数和畸形精子指数有影响。

The biological polymorphism of Cercospora zeae-maydis was studied systematically in the levels of histology, protein and DNA. The major characters in polymorphism of pathogen were listed as follows:(1) The great differences were seen in shapes and sizes of conidiophores, the growth velocity of mycelium and pigment-productivity of colony among pathogen strains. In addition, an albino strain, a kind of mutant, was casually discovered during isolation of pathogen from diseased plants, which supported strongly our previous prediction that there should be some potential genetic variation in Cercospora zeae-maydis.

本研究在组织学、蛋白质和DNA水平上，系统研究了玉米灰斑病菌的生物学多态性，这种多态性主要表现在以下几个方面：①病菌形态学和培养性状多态性：菌株间存在分生孢子形态、菌丝生长速度、菌落产色素能力等方面的差异，该病菌在自然界存在另一种变异类型——白化菌株，说明灰斑病菌的确存在遗传变异的潜能。

To make the classification of Helminthism of the livestock and poultry more convenient and short-cuting, the key system was set up by the programming language of Visual Basic. According to the morphologic characters of the orders, families and genuses of Cestoidea, Trematoda and Nematoda, a database was established. The correlative data can be searched easily and quickly.

为了使畜禽寄生蠕虫形态学分类更加方便、简捷，采用Visual Basic可视化的计算机编程语言，根据绦虫纲、吸虫纲、线虫纲和棘头虫纲的各目、科和属的虫体形态特徵建立数据库，通过资料查询系统，可方便快捷的对相关资料进行查询。

Objective:By histochemical method, the four biotinylated lectins (DBA, SBA, WGA, UEA 1) were used to study changos in glycoconjugate expression on the surface of endometrium of 28 cases of RSA without obvious reasons in secretary phase, at the same time, endometrial biopsies were taken for histomorphologic evolution.

本文通过生物素分别标记的双花藕豆凝集素、大豆凝集素、麦胚凝集素及荆豆凝集素（UEA－1）与子宫内膜的反应，应用S－P法研究28例无明显原因反复流产的分泌期子宫内膜糖复合物的变化及与其组织形态学分期的相关性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
