氮化作用

In the present study changes of NOS positive cells after injection of LPS and apoptotic ependymal cells, the relationship between expression of immediate early gene c-fos and astrocytes, and comparison of changes between SFO and rest regions of the brain in different time-points were investigated with NADPH-d histochemistry, apoptosis in SITU detection of TUNEL, TEM and SEM, fluorescein double labeling of immunohistochemistry, and laser scanning confocal microscope.

为了证实穹窿下器在脑内免疫调节系统中的作用，在本研究当中，应用了NADPH刁的组化方法、TUNEL末端标记法、扫描及透射电镜方法、免疫组织化学的荧光双标法及激光扫描共聚焦显微镜技术，来研究在腹腔内给予大肠杆菌内毒素后，脑内的一氧化氮合酶细胞的变化、室管膜细胞的凋亡、早期即刻基因（immediate early genes沁－fos的表达与星形胶质细胞之间的关系，以及穹窿下器与其它脑区相比较时的特异性改变。

Methods MTT Chromatography is adopted to test effects of 5-FU of different concentration and at different time of reaction over growth of Lovo cells; photomechanical method used to observe configuration and characteristics of apoptosis cells; FCM employed to test the percentage of apoptosis cells; electrophoresis and immunized grouping SP applied to test antigen Ki-67 of Lovo cells proliferation and expression of P53 and Fas genetic proteins in relation to apoptosis.

采用四甲基偶氮唑盐显色法，检测不同浓度5－FU作用不同时间对Lovo细胞生长所产生的不同影响；光镜观察凋亡细胞的形态特点；流式细胞术检测凋亡细胞百分率；琼脂凝胶电泳、免疫组化SP法检测 Lovo细胞增殖核抗原Ki－67及凋亡相关基因蛋白p53、Fas表达水平。

Scenedesmus sp. isolated from sewage was entrapped in calcium alginate gel for tertiary treatment of the artificial wastewater.

利用固定化藻类的生物富积作用净化污水中的氮和磷，将栅藻包埋固定在褐藻酸钙凝胶胶球中，对人工污水进行深度净化。

Biogenic amines are basic nitrogenous compounds formed mainly by decarboxylation of amino acids or by amination and transamination of aldehydes and ketones.

生物胺是一类含氮的脂肪族、芳香族或杂环类低分子化合物，主要是通过氨基酸的脱羧或醛和酮的胺化和转氨基作用形成的。

The specific inhibitor of DNA methylation that is available currently is 5-Aza-2'-deoxycytidine (5Aza-dc), which forms a covalent bond with the DNA methyltransferase, thus, limiting the number of free DMT molecules for methylating DNA and then decreasing its biology activity.

目前研究较多的甲基化抑制剂是胞苷类似物5-氮杂-2'-脱氧胞苷(5-Aza-2'-deoxycytidine， 5Aza-dc)。5Aza-dc的作用机制是与DNA甲基转移酶共价结合，降低酶的生物活性。

The bubble contours were extracted from the experimental images by means of Matlab toolboxes.

对氮气泡在电场作用下的形成过程进行了可视化研究。
