[Changes in the nasal mucosal microvascular with allergic rhinitis].
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.
