cytoxicity was observed at 2.5 log10. 细胞毒性 为 2.5 log 10 Explanation: Is it "cytoxicity" or "cytotoxicity"??? I tried to find if there is any difference but I didn't get any good result. If they are the same, then here's my answer: CYTOTOXICITY: Quality of being capable of producing a specific toxic action upon cells of special organs. Cytotoxicity = 细胞毒性 简明英汉汉英医学词典 |

所观察到的细胞毒性为2.5 log10 Explanation: Cytoxicity = 细胞毒性 在科学实验中处理数据时经常取其对数后绘图(换言之,使用对数坐标),使图形比例可以大为缩小;另一方面,对数运算有许多方便之处。log代表以10为底的对数。因log 10 = 1, 故log (10的n次方) =n log 10 = n。从这点出发试答上述问题如下: Question No.1: Does "Cytoxicity was observed at 2.5log10" mean there are about 10 2.5 viruses causing cytoxicity? No. It means about 10的2.5次方 viruses were killed? Question No. 2: what does the “(2.5 log 10 for both cycles)” mean? It just emphasizes “Cytoxicity was observed at 2.5 log10 for both cycles”. Question No.3: How did they calculate the 3.75 and 4.0 log reductions? 6.25 log10 - 2.5 log10 = 3.75 log10 6.5 log10 - 2.5 log10 = 4.0 log10 以上谨供参考,希望能以此抛砖引玉。 -------------------------------------------------- Note added at 2004-02-05 20:05:49 (GMT) -------------------------------------------------- After reading the text again, I think I should make a correction to the answer for Question No.1 as follows: \"Cytoxicity was observed at 2.5 log10\" means \"Cytoxicity was observed at the titer of 2.5 log10\", i.e., 当滴定量为2.5 log10时观察到细胞毒性。 -------------------------------------------------- Note added at 2004-02-06 02:34:59 (GMT) -------------------------------------------------- log A - log B = log (A/B) So, (10的6.5次方)除以(10的2.5次方)equals 10的4次方 -------------------------------------------------- Note added at 2004-02-06 06:03:51 (GMT) -------------------------------------------------- 我所用的公式log A - log B = log (A/B)是对的。6.5 log10 - 2.5 log10 = log(10的6.5次方) - log(10的2.5次方) = log [(10的6.5次方)/(10的2.5次方)] = log (10的4.0次方) = 4.0 log10 。另一方面,因 log 10 =1,故6.5 log10 - 2.5 log10 = 6.5 - 2.5 = 4.0 = 4.0 log 10。 infectivity 和cytotocity确实是两回事。Infectivity是传染性。至于其它问题,我再查一查,你也可以问一下这方面的专家或你的用户。实在没有办法时就把语法关系搞清楚按照字面翻译,应该不会错。有些很专业的论文你要想完全从专业角度搞清楚恐怕很难。当然你的精神很好。 -------------------------------------------------- Note added at 2004-02-06 15:12:28 (GMT) Post-grading -------------------------------------------------- FYI: 所谓4.0 log reduction 的概念是病毒数量下降到原来的1/10,000(即10的4次方之一)。 |
