Nasal mucosal provocation tests were done on eight patients with seasonal allergic rhinitis before and after a birch pollen season. The effects on nasal microvascular blood flow were detected by means of laser Doppler flowmetry. The patients reacted to the birch pollen provocation with an increase in blood flow. This increase was greater after the pollen season than before, when the same pollen doses were used, indicating a priming phenomenon of the resistance vessels.
在桦树花粉季节前后，对8名季节性过敏性鼻炎患者进行了鼻黏膜激发试验。通过激光多普勒血流仪检测对鼻微血管血流的影响。患者对桦树花粉激发的反应是血流增加。当使用相同花粉剂量时，这种增加在花粉季节后比之前更大，表明阻力血管存在致敏现象。
