Method for the determination of oxytetracycline , tetracycline , chlortetracycline , and doxycycline residues in honey - liquid chromatographic method 蜂蜜中土霉素四环素金霉素强力霉素残留量的测定方法液相色谱法
People on tetracyclines , especially doxycycline , are more prone to sunburns . sun protection is therefore important in summer 四环素类别的药物，尤其是doxycycline ，会使皮肤较容易晒伤，在夏天服用时，应作防晒保护。
Jiupeng co . , is one of the largest manufacture of api doxyoycline hcl , doxycycline mono , methacycline hydrochloride , etc . welcome to contact with us 久鹏公司是中国最大的强力霉素、一水物等抗生素原料生产商之一，欢迎各界朋友洽谈，联系。
To see what was going on , he labelled the doxycycline - resistant strain with a yellow protein and the sensitive strain with a blue protein 为了观察进行情况，他用黄色蛋白质标记耐脱氧土霉素的大肠埃希菌，用蓝色的蛋白标记对脱氧土霉素敏感的细菌。
This time it was the doxycycline - sensitive strain that did better even though , in principle , it was not resistant to either drug 第二个实验中，甚至从理论上来说对两种抗生素都无耐药性的这种菌群，反而生长得比拥有对脱氧土霉素耐药的菌群要好得多。
The lifetime of each sensor is at least three to four months . the sensor can be used for direct determination of doxycycline in pharmaceutical preparations and urine samples 用传感器测定药片中呋喃唑酮含量的平均值和标准偏差与药典中的标准方法分光光度法测定的结果一致。
However , when the researchers grew each strain in cultures containing both doxycycline and a second antibiotic , ciprofloxacin , they found the opposite effect 然而，当研究人员将两个菌群置于脱氧土霉素和另一种抗生素（环丙沙星）同时存在的环境中时，他们发现结果与头一种情况下的截然相反。
The 10 chemicals for which we have prescribed mrl are cloxacillin , dicloxacillin , ampicillin , amoxycillin , benzylpenicillin , sulfonamides , chlortetracycline , oxytetracylcine , doxycycline and tetracycline , " the spokesman said 这十种化学物分别为邻氯青霉素、双氯青霉素、氨苄青霉素、羟氨苄青霉素、苄青霉素、磺胺类药、金霉素、土霉素、强力霉素及四环素。
Doxycycline gums up the assembly line on which proteins are made , whereas ciprofloxacin stops the dna message about how to make each protein being read in the first place , so there is plenty of scope for interference between the two 脱氧土霉素是通过黏附在蛋白质生产线来阻止细菌蛋白质合成的，而环丙沙星是通过阻抑指导蛋白合成的dna遗传信息的读取过程来祈祷抗菌作用的。
It is an important that bacteria contaminated vaccine in the biologicals production . we collected 703 samples of cell culture , virus cultivation and harvest which were contaminated by bacteria during poliovaccine production within two years . we checked these samples by bacteriological method and antibiotics sensitivity tests were done . it shows that 1 ) the main contaminated bacteria come from staphylococci , bacilli and streptococci of environment in the poliovaccine production . 2 ） it is effect that antibiotics to contaminated bacteria are doxycycline , albiotic , prescription 2 , cefotaxime na salt , gentamycin , neomycin , aureomycin and erythromycin 在疫苗生产实践中，细菌污染是影响疫苗质量和产量的关键性因素，笔者通过了两年左右的时间，选取正常生产中零星细菌污染的细胞培养瓶、病毒培养瓶及收毒污染样品等共703份，进行细菌学检查，并对造成污染的主要细菌种类进行了各种抗菌药物的耐药性实验，结果表明：我所脊灰疫苗生产中主要的污染威胁来自环境中的葡萄球菌，潜在威胁是杆菌和链球菌；强力霉素、林可霉素、配方2 、噻孢霉素钠盐、庆大霉素、新霉素、金霉素和红霉素等抗生素对目前引起污染优势细菌-葡萄球菌有明显的抑菌效果，可作为疫苗生产后备抗菌手段参考
