統整歷年考古涵蓋的Bradykinin的功能
1.血管擴張
2.輕微利尿
3.降血壓(前兩者的綜合結果)
4.非血管的平滑肌收縮(例如:氣管、腸道)
5.接收疼痛
6.促進arachidonic acid及其代謝產物的生成
7.增加血管通透性

Bradykinin is a potent endothelium-dependent vasodilator and mild diuretic, which may cause a lowering of the blood pressure. It also causes contraction of non-vascular smooth muscle in the bronchus and gut, increases vascular permeability and is also involved in the mechanism of pain.
