The role of bradykinin in process of inflammation is: (A) Vasoconstriction, (B) Bronchiodilatation, (C) Pain, (D) Increase in vascular permeability
Answer is D. Ref Robbins 8/e p65- 66 ; 9/e p89 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.
