Objective To determine the effect of systemic dexmedetomidine on the median effective concentration (EC50)of propofol target-controlled infusion (TCI)for respiratory depression.
目的研究右旋美托咪啶对丙泊酚靶控输注(TCI)时患者呼吸抑制的半数有效浓度(EC50)的影响。
参考来源 - 右旋美托咪啶对丙泊酚靶控输注患者呼吸抑制半数有效浓度的影响Streptomycin sulfate was not only the best effective to inhabit the pathogen, but also the lowest effective concentration to inhabit pathogen, so streptomycin sulfate was the preferred bactericide to Erwinia rhapontici for field trial.
农用链霉素不仅抑菌效果明显,而且抑菌最低有效浓度也最低,农用链霉素应为穿龙薯蓣细菌性顶枯病田间药效试验的首选药剂。

The effective density of "medical powder" to Trichodina is 1.5g/m~3and 0.012g/m~3 for "medicament".
在安全浓度以内,粉剂和水剂各设7个浓度梯度及空白对照,通过治疗感染车轮虫的草鱼夏花试验,得到“粉剂”对车轮虫的有效浓度是1.5g/m~3;“水剂”对车轮虫的有效浓度是0.012g/m~3。
