分析物的峰高与浓度之间存在较好的线性关系，麻黄碱和伪麻黄碱的检测限分别为2.39×10~(-3)和3.85×10~(-3)μg 1~(-1)。

There are other thermogenic fat burners on the market that provide decent results besides ephedrine.

市场上还有除麻黄碱以外能够提供出色效果的其他热性燃脂产品。

If the cause is loss of volume, intravenous fluids should be supplemented; if vasodilatation (f. ex. due to large doses of epidural analgesia or habitual anti-hypertensive medication), the treatment is not fluid but is the dose adjustment of the provoking factor or vasoconstricting agents as e.g., Ephedrine.

如果低血压由液体不足引起，应增加静脉补液量；如果血管扩张（例如，因为大剂量硬膜外麻醉或习惯性的抗高血压治疗），则不需液体治疗而是调整扩血管药物的剂量，或使用血管收缩剂，比如麻黄碱。

In the strips isolated from reserpine pretreated rabbits, the actions of NA and E were potentiated; the potentiation of E was greater than that of NA.

利血平处理后，麻黄碱和NA的作用都明显增强，但利血平对前者的增强作用比后者更甚。

40 primiparas were punctured from lumbar 2~3 spinal interspace and injected a 2.2ml mixture (2.5% chloroprocaine 1.2ml, 10% glucose 0.5ml, 3% ephedrine 0.5ml) within 30~40 seconds into subarachnoid space.
