查询词典 toxic

Micronucleus test results exhibited that significant differences in micronuclear rates were determined between 0.4 mL bone cement and 0.4 mL microsphere-coated bone cement groups and negative control group, but no significant difference was detected among other groups. This revealed that this microsphere-coated bone cement leaching liquor did not show significant cell heredity toxic effects. Nevertheless, microsphere-coated bone cement in the high concentration and high dosage groups exhibited low toxic effects, mainly showing increased hemolysis rate and micronuclear rate. Thus, it was necessary to control the dosage and concentration of microsphere-coated bone cement.

微核实验结果显示除0.4 mL骨水泥组和0.4 mL微球骨水泥组的微核率与阴性对照组差异有显著性意义，其余各组差异无显著性意义，说明该微球骨水泥的浸提液无明显细胞遗传毒性作用，但是高浓度和高剂量组的微球骨水泥仍有较低的毒性作用，主要表现为溶血率和微核率的提高，因此在应用时要适当控制微球骨水泥的剂量和浓度。

MDA content, cell division , he activities of NR, CAT, POD and SOD of Pistia sagittifolia and Myriophyllum Spicatum with heavy metal,s ion concentration to appear a trend of ascending firstly and desending secondly . This trend explains that Pistia sagittifolia and Myriophyllum Spicatum on the Toxic Effects have similarities under handing the single Pb2+ and Hg2+. As the range of the concentration which each index is arriving at the maximum is different, this also indicates that there are some differences of the Toxic Effects between Pistia sagittifolia and Myriophyllum Spicatum under handing the single Pb2+ and Hg2

丙二醛含量、脂膜透性、硝酸还原酶活性、过氧化物酶活性、超氧化物歧化酶活性、过氧化氢酶活性随重金属离子浓度的增加呈先升后降趋势，说明在单一Pb2+和Hg2+处理下大薸和穗状狐尾藻毒害效应具有相似性；但各指标到达最大值的浓度范围不同，又说明单一Pb2+和Hg2+处理下大薸和穗状狐尾藻毒害效应具有差异性。

通过测定培养液中的LDH的活力变化，可间接反映Aβ对神经细胞的毒性作用及药物抗Aβ神经毒性的能力。

Polyaspartamides including PAEA(1), PAAPA, PADAOA and low molecular weight PAHA are markedly less toxic than poly and poly, however, PABA and higher molecular weight PAHA are slightly less toxic than poly.

与聚赖氨酸和PEI相比，PAEA（1）、PAAPA、PADEOA以及低分子量的PAHA具有明显低的细胞毒性；而PABA与高分子量PAHA的细胞毒性较聚赖氨酸略低。

The drug of Xin xiebai powder can raise the content of SOD , at the same time reduce the content of the toxic oxygen free radicals and the injury by lipid peroxidate and lighten the lung damage by the oxidation effects of stress reaction.It confirms the security of Xin xiebai powder by acute toxic experiment.

能够提高机体 SOD 的含量，从而减轻毒性氧自由基的含量，降低机体内脂质过氧化，减轻氧化应激反应引起的肺损伤。

Instead of environmentally toxic chromium oxidant, singlet oxygen generated photochemically was used as environmentally friendly and benign oxidizing agent to accomplish the transformation of pseudodiosgenin diacetate to diosone efficiently in a low toxic and less expensive solvent acetone.

裂解薯蓣皂甙元所得的假薯蓣皂甙元，在低毒且廉价的丙酮溶剂中，在光敏剂和光的存在下，与氧气反应，得到的产物再经酸解消除反应得到合成其它多种甾族药物的重要前体16-脱氢孕烯醇酮醋酸酯。

Dissimilatory Fe oxide reduction under anaerobic condition is a process which is an anaerobic respiration with Fe as the terminal electron acceptor. This anaerobic respiration showed important environmental significances. Dissimilatory Fe reducers can use diverse electron acceptors including many toxic heavy metals and metalloids such as Mn、Cr、Co insides Fe. So these toxic metals were detoxified or were immobilized reductively.

这种厌氧呼吸作用具有重要的环境学和地学意义，Fe还原微生物可利用除Fe以外的许多其它电子受体包括许多有毒重金属和类金属，如Mn、Cr、Co等，从而对这些有毒重金属起到还原解毒或还原固定的作用；还原过程还可促进一些有机污染物的降解； Fe氧化物的还原偶联着Si、P等元素的变化，对提高这些营养元素的有效性发挥着重要作用。

Debbie Mandel has another warning for those confronting toxic friends:"Listen to their side of it because perhaps it's you who is toxic."

黛比&孟德尔又警告那些要面对有毒朋友的人：&听听他们那一面的说辞，因为也许你正是那个有毒的朋友。
