Abstract

In subjects with allergic rhinitis to house-dust mite (HDM), antigen challenge produced a significant increase in nasal blockage but had no effect on nasal vascular permeability. The B2 kinin receptor antagonist, [D-Arg0,Hyp3,Thi5,D-Tic7,Oic8]-bradykinin (Hoe 140), 200 micrograms administered by intranasal aerosol 2 min prior to challenge with HDM, 500 u significantly reduced nasal blockage induced by the antigen challenge. The data are compatible with a role for B2 kinin receptors in the nasal response to challenge with antigen which is responsible for nasal blockage.

摘要

在对屋尘螨(HDM)过敏的鼻炎患者中,抗原激发可导致鼻阻塞显著增加,但对鼻血管通透性无影响。在用500单位HDM激发前2分钟经鼻气雾剂给予200微克B2激肽受体拮抗剂[D-Arg0,Hyp3,Thi5,D-Tic7,Oic8]-缓激肽(Hoe 140),可显著减轻抗原激发引起的鼻阻塞。这些数据表明B2激肽受体在对抗原激发的鼻反应中起作用,而这种反应会导致鼻阻塞。
