微核

According to the advance of research of tradescantia ecotoxicology all the world, this paper summarized the advance of research and significance of new problem of Tradescantia micronucleu mechanisms and tradescantia stamen hair mutation mechanisms, and the development of the probe test technology, quantification test technology and tradescantia ecotoxicogenome and so on in order to give a reference to research the tradescantia molecular toxicology.

文章从国内外紫露草生态毒理的研究现状出发，针对紫露草微核产生及雄蕊毛突变机制这类新问题的研究现状及意义，以及探针检测技术、定量检测技术和紫露草的生态毒理基因组学的发展等方面进行综述，为紫露草分子毒理上的研究提供参考。

As exposed to optics microscope and inverted microscope,compared to control,SW480 cells with Giemsa staining that treated with the H2RA(cimetidine、nizatidine) took on malignance declining as crimpled firstly,cellular bulk and heteromorphism dimimished,the amount of rounded cell manifolded,nucleolus bulk lessened,dyeing thin,the amount of nucleolus decreased,partial cell organs manifest side-gathering phenomenon on chromatin,and the link between SW480 cell is loosened , subsequently partial rounded cell is floated.When the H2RA(cimetidine 40μM、nizatidine 20μM) against SW480 cells after 3 day,SW480 cells change roundly,nucleolus smashed,shrinking nucleolus came into being,and part of those not adhibited cell wall.

在光镜和倒置相差显微镜下，与对照组相比，经姬姆萨染色观察，西咪替丁、尼扎替丁处理的SW480细胞，先发生皱缩，体积变小，异形性减少，细胞变圆数目增多，细胞核变小，染色变淡，核仁数量减少，部分可见染色质边集现象；细胞间连接疏松，随后部分变圆细胞浮起。40μM西咪替丁及20μM尼扎替丁连续处理3天后，SW480细胞全部变圆，细胞核碎裂，固缩微核形成，部分不再贴壁。

Results: The count of human peripheral blond lymphocyte is related to classes of work and cumulated absorb dose.

结果：放射工作人员外周血淋巴细胞微核率与工种、累计吸收剂量等因素有关。

The use of common proportion of transgenic CryIA cotton seed powder in fish's feed does not induce the increase of micronucleus frequency obviously.

Methods lymphocytes in culture fluid were treated by supplementing different doses of trichlorfon , then the changes of micronucleus rates were observed .

用不同浓度的敌百虫溶液处理培养中的淋巴细胞，观察其微核率的变化，并用χ 2检验方法做显著性检验。

Methods Micronucleus test: Kuming mice were divided into 3 groups at the dibutyl phthalate dosage of 33,330,3 300 mg/kg,and the bone-narrow micronucleus test was undertaken according to the routine method.

选择妊娠期和哺乳期SD雌性大鼠，灌胃染毒，DBP剂量分别为0、125、250、500 mg/kg，计数F1代雄性大鼠的附睾尾精子数、精子活力、精子畸形率。结果DBP在3 300 mg/kg时能引起微核率的升高(P.01)。

It was typically indirect effect that the following variations induced in the progenies of endosperms implanted by heavy ion beams were discovered. 1 In comparison with control, there were very high differences in biological trait, anti-oxidation enzyme activity, MDA content and protein content, chromosome aberration rate and micro-nucleus rate in M1 generation. 2 Shorter stem variants and purple stem mutants were analyzed by RAPD and AFLP. The analytic results showed that the sequences of their DNA were changed, so those variations were not physiological damage only. And there were differences among M2 generation plants of the same sort of variants or mutants, it was indicated that M2 generation may be in disjunction.

M1代的生物学性状、幼苗的抗氧化酶活性、MDA含量、蛋白质含量和染色体畸变率及微核率等发生了较大的变化。2）对其矮杆变异株和紫色茎杆突变体（M2）做RAPD和AFLP分子鉴定等研究，结果显示了矮杆变异体和紫色茎杆突变体的DNA序列发生了改变，而非仅仅产生生理损伤；同一种变异体或突变体，在M2代单株间也存在着明显的差异，表明它们可能还处于分离状态。

Mach is a microkernel developed at Carnegie Mellon University and then at the University of Utah; the GNU HURD is a collection of servers (or ''herd of gnus'') that run on top of Mach, and do the various jobs of the Unix kernel.

Mach是在卡耐基梅龙大学，后在犹他大学开发的微核；GNU HURD是一个运行于Mach之上的服务器集合，完成Unix核心的各种任务。

Bone marrow polychromatic erythrocyte micronucleus rates of jimpy mice fed with different dosage olaquindox was detected by the way of toxicology,and the number of red blood cells,white blood cells and granulofilocyte was mensurated after 30 days.
