The nasal mucosal microvascular of 37 patients with allergic rhinitis had been studied by nasal mucosal microcirculation microscope. It was found that the nasal mucosal microvascular diameter was wider after the nasal challenge test than before, but both after and before the nasal challenge test, the nasal mucosal microvascular diameter in patients with allergic rhinitis was narrower than in normal persons. The number of the microvascular in patients was also less than that in normal persons. The results indicate that the nasal mucosal microvascular with allergic rhinitis are characterized by dilated capacitance vessels and exchange vessels and constricted resistance vessels after nasal allergen challenge.
应用鼻黏膜微循环显微镜对37例变应性鼻炎患者的鼻黏膜微血管进行了研究。发现鼻激发试验后鼻黏膜微血管直径比激发试验前增宽，但无论是激发试验后还是激发试验前，变应性鼻炎患者的鼻黏膜微血管直径均比正常人窄。患者微血管数量也少于正常人。结果表明，变应性鼻炎患者鼻黏膜微血管在鼻过敏原激发后具有容量血管和交换血管扩张、阻力血管收缩的特点。
