- 方法:采用WHO药物统计合作中心设定的限定日剂量(defined daily dose,DDD)方法计算我院抗菌药物的用药频度。METHODS: The DDDs of anti-infectives in our hospital were computed using defined daily dose(DDD),which was set by WHO Drug Statistical Cooperation Center.
- 采用MTT实验、溶血试验、微核试验、小鼠LD50 (median lethal dose)检测等方法评价Fe_3O_4磁性纳米粒及As_2O_3/Fe_3O_4复合纳米粒的生物相容性;Thermodynamic test was used to observe temperature change of various doses of Fe_3O_4 nanoparticles and nanosized As_2O_3/Fe_3O_4 complex under alternating magnetic field (AMF).
- 本文讨论了现有巡测仪测量中子周围剂量当量(Ambient Dose Equivalent)H·(10)的适用性问题,并扼要阐述了微剂量计数器和 Bonner 球计数器在这方面的应用。The main aspects of the suitability of existing survey meterin the measuring of neutron ambient dose equivalent were discussed and theapplication of microdosimetric counter and Bonnet Sphcre Counter in thisaspect was briefly described.
- 采集受试者不同时间点的呼气标本并检测13C丰度,绘制丰度(delta over baseline,DOB)曲线、代谢速率(metabolisation velocity,MV)曲线和累积丰度(cumulated dose,CUM)曲线。An oral dose of 75mg nonradiative tracer 13C-methacetin was administered to each subject. Breath test was taken before and different intervals within 120 minutes after the administration. The results were expressed as three curves:delta over baseline (DOB),metabolisation velocity curve (MV) and cumulated dose curve (CUM).
