n.降肾上腺素；去甲肾上腺素
Levels of epinephrine and norepinephrine increased significantly after the music therapy sessions but had returned to pretherapy levels 6 weeks after the sessions had been stopped. 肾上腺素和降肾上腺素也在音乐疗程后大量增加，但在疗程结束的六周后即恢复到原来的数量。
Some hypertensive patients have defective storage of norepinephrine, thus permitting more to circulate. 有些高血压病人存在去甲肾上腺素贮存缺陷，造成较多的去甲肾上腺素进入循环。
Thus, inhibition of this mechanism could conceivably enhance the effect of norepinephrine. 因此可以想象，抑制这种机制可以增强去甲肾上腺素的作用。
