The results indicatethat the expression of Cyt1A alone could result in the cytolysis of host bacterial cells,and both P20 and Cry11A could prevent bacterial cells from cytolysing caused byCyt1A protein.

为了进一步探讨P19和P20对Cry11A和Cyt1A相互作用的影响，本研究构建了表达P19、P20、Cry11A和Cyt1A不同组合的七个Bt重组菌株，分别从目的蛋白表达、营养细胞生长、芽胞和晶体形成、杀虫毒力等方面进行了研究。

Using BG11 as base media,the toxic effects of heavy metal Cu2+on alga Microcystis aeruginosa were studied according to the change in growth,chlorophyll-a,photosynthesis release oxygen and respire exhaust oxygen of the M.aeruginosa under different Cu2+ concentrations in the experiment conditions.

以BG11为基础培养基研究了实验室条件下重金属Cu2+在不同质量浓度下对铜绿微囊藻的急性毒性效应。试验结果表明，Cu2+对藻类的抑制效应随Cu2+质量浓度的增加而增加：质量浓度为0.3~1.2 mg/L的Cu2+对铜绿微囊藻生长的抑制作用不显著，且48 h后出现藻细胞密度反弹现象，杀藻效果不理想。

This night facial wash contains sterilizing formula and millions of scrub that goes deep down into pores to leave skin feeling clean without stripping natural moisture.

此款药用夜间洗面胶，具有杀毒消菌的特殊配方，消除脏污，卸下一整天下来脸上的尘垢，并含有清洁颗粒，能细腻深入毛细孔，去除角质和老旧细胞，还能预防粉刺，使用后感觉清透乾净，毫不感觉乾涩，让你清爽入眠。

IL 1β and IL 6 levels in supernatant of homogenates of cerebral cortices were measured by the Enzyme Linked Immunosorbent Assay.

28只C57BL/6J雄性小鼠接受MPTP 25 mg/kg ip注射连续5 d，对照组（10只）注射生理盐水，在最后一次注射的第1（10只），第3（8只）和第14日（10只）杀鼠，然后用酶联免疫吸附的方法检测大脑皮质匀浆液上清内细胞因子IL 1β和 IL 6的水平。

However, the Cry1Ac-GFP fusion protein only accreted with peritrophic membrane of resistant strain and showed fluorescence, which suggested that the binding of peritrophic membrane with Cry1Ac toxin protein may result in resistance of larvae of H. armigera to Cry1Ac insecticidal crystal proteins.

比较Cry1Ac杀虫蛋白敏感和抗性棉铃虫幼虫中肠的发光部位，敏感棉铃虫幼虫的中肠围食膜已经消失，肠壁细胞发出强烈的荧光，而抗性棉铃虫的围食膜较健全并发出荧光。

It has been reported that the leaf and root extracts of Petasites hybridus relieve gastrointestinal pain, lung-disease such as asthma and cough, as well as spasms of the urogenital-tract, and even suppress the proliferation of human T24 bladder carcinoma cells. In 2000, S-petasin had been found to decrease the testosteron releasing by rat testicular interstitial cells.

此植物体及其萃取物应用在治疗使用上已约有两千年的历史，在1994年的研究中指出其粹取物对於人类膀胱癌细胞株（T24）具有抗增殖的效果，且於2000年，本实验室研究发现其粹取物-硫蜂斗菜素具有抑制大鼠间质细胞分泌睪固酮的效用，然而它对於人类前列腺癌细胞株是否也会造成毒杀效应，目前则尚未有文献探讨。

The fiber film material with the radioactive nuclide mark is covered at a tumour part or a lesion tissue part after resection, thereby effectively killing the residual tumour cells, and playing roles in stanching, healing wound and preventing adhesion and so on.

将上述放射性核素标记的纤维膜材料包裹在肿瘤或手术切除后的病变组织部位，对残余的肿瘤细胞进行有效灭杀，可以发挥纤维膜的止血、促进伤口愈合以及防粘连等功能。

We used the derivatives to do the MTT assay test and to discuss the SAR, the result teld us the isoprenyl group and the 3,4-olefinic bond of osthol is essential for its activity,and the isoprenyl group at position 8 had the better cytotoxicity. When osthol and demethylsuberosin reacted with ferulic acid to form the derivatives of (26) and (35) have the better effect of anti-cancer and IC50 value than osthol.

所以我们选择蛇床子素进行结构上的修饰并与姜黄素的部分结构形成的化合物ferulic acid结合合成出一系列的衍生物，进行抗癌细胞毒杀活性测试来探讨其结构与活性的关系，发现osthol上的isoprenyl group对於抗癌活性有重要的影响，且isoprenyl group位於C8的位置对於抗癌活性有较好的表现。

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。
