Porphyridium cruentum were treated with some antibiotics which were used as genetic selected marks in genetic engineering. The results showed that the algae cells could resist high concentration of Penicillin,Streptomycin,Gentamicin and Kanamycin, without any influence at the dose below 100 u/mL of which can kill bacterium adhere to the algae cells . These antibiotics can be used to repress bacterium in purifying algae strain.Porphyridium cruentum is high sensitive to Erythromycin,Terramycin and Ofloxacin....

研究了基因工程中常用抗生素标记对紫球藻的生物学效应，结果表明紫球藻对青霉素、链霉素、庆大霉素以及卡那霉素较不敏感，剂量在100u/mL以下对其生长无显著影响，但能抑制或杀灭伴生的杂菌，因此这些抗生素可用于藻种纯化过程中抑菌；紫球藻对红霉素、氧氟沙星和土霉素非常敏感，低质量浓度就能杀死藻细胞，可用作基因工程或遗传育种的抗药性选择标记；对四环素和氯霉素较为敏感，明显抑制细胞生长，并呈浓度梯度效应。

this paper briefly introduced the diseases mediated by Asian tiger mosquito and the damages caused, then introduced the research status of its resistance, the effectiveness of info-chemicals on it, and its transgenic technology both in China and in foreign countries.

本文简单介绍了白纹伊蚊传播的疾病及其危害，并介绍了国内外在白纹伊蚊抗药性、信息化合物对白纹伊蚊的影响及白纹伊蚊转基因技术研究等方面的研究现状。

In this study, differences among tolerant capabilities of three species of nitrogen-fixation cyanobacteria (Anabaena azollae, Anabaena flos-aquae, Anabaena azotic) to two new sulfonylurea (Monosulfuron and Monosulfuron ester) were studied, which could be used to further explain the resistant mechanism to sulfonylurea herbicides and how these herbicides take effect.

本文以满江红鱼腥藻、固氮鱼腥藻及水华鱼腥藻为代表，利用环境毒理学的研究手段，通过研究3种固氮蓝藻对2种磺酰脲类除草剂---单嘧磺隆、单嘧磺酯的耐药性差异来揭示对磺酰脲类除草剂产生抗药性和耐药性的机理。

The results also showed that N-cadherin mediated adhesion participated in the chemoresistance of N-cadherin positive cells.

VP16作用于N-cadherin阳性细胞的IC50(220μmol/L)显著高于N-cadherin阴性细胞(151μmol/L)(p=0.04)；N-cadherin介导的黏附参与了N-cadherin阳性细胞的抗药性。

The inter function of biology system can be reflected from it. The vary regulation when biology system is stimulated by environment can be used in cancer diacrisis, drug fustness of germ, environmental monitoring, etc.

研究生物组织在接受外界刺激时延迟发光的变化规律在癌症诊断、病菌的抗药性、农作物的抗逆性、食品安全以及环境污染监测等众多领域具有广泛应用前景。

The results indicate that the low level resistance to tribenuron-methyl in the biotype of Galium aparine from Xuchang, Henan Province, is based on the excessive expression of ALS and the enhancement of tribenuron-methyl metabolism resulting from GSTs, not due to the sensitivity of ALS. In the meanwhile POD and SOD may play a role in alleviating the spray injury.

抗药性生物型猪殃殃对苯磺隆产生抗性的原因可能是ALS过量表达及GSTs对苯磺隆的代谢作用加强，而不是由于ALS的敏感性下降，同时POD、SOD在减轻药害中也具有一定作用。

There was no cross resistance between chlorate and MBC in G. zeae. Therefore, the nit can be used as gnetic marker for study the genetics of MBC resisance in homothallic fungus G.

因此，可用nit作为遗传标记，研究具同宗配合特性的玉蜀黍赤霉对多菌灵的抗药性在有性重组过程中的遗传与变异。

Besides, 48.5%(n=157) suffered from acute RS; 8.0%(n=26), subacute RS; and 43.5%(n=141), chronic RS. Mucopus were obtained from their nasal cavities, and then transmitted for aerobic bacterial cultures with sensitivity test of antibiotics.

根据就诊当下症状期的长短，可以区分为急性（10天~4周）157名、亚急性（4~12周）26名及慢性（12周以上）141名，采集鼻道脓液进行嗜氧菌的培养，并测试其对抗生素的敏感性或抗药性。

We concluded that sputum cultures in the Taipei Hospital Branches for Communicable Disease Control revealed that 4.06% were multi-drug resistant strains of Mycobacterium tuberculosis and a very high percentage of multi-drug resistance in Nontuberculous Mycobacterium, which requires the attention of health workers.

研究分析结果显示台北市立联合医院疾病管制院区所培养分离的菌株中结核分枝杆菌多重性抗药菌比例达4.06%，但非典型结核分枝杆菌抗药性之菌株比例却非常的高，值得密切的注意。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
