Nasal Mucosal Hemodynamics in Nasal Allergy

Although nasal mucosal hemodynamics in nasal allergy has been studied by various methods, it is still obscure. Using a tissue spectrum analyzer, we measured ISO2 and IHb in the nasal mucosa of patients with nasal allergy. ISO2 and IHbindicate O2 saturation in hemoglobin and tissue blood volume, respectively.i) In general, little difference in ISO2 or IHb was found beween patients with symptoms and patients without symptoms.ii) IHb in patients with perennial nasal allergy seemed to decrease when they had symptoms. On the other hand, IHb in patients with seasonal nasal allergy seemed to increase when they had symptoms.iii) In three patients with Japanese cedar pollinosis, IHb was increased during the season and was decreased at other times.
