Triad of allergic rhinitis are nasal obstruction, watery discharge and sneeze. We studied the change of nasal respiratory resistance both before and after sneeze in the nasal provocation test using antigen disks. We also studied the effect of sneeze in the nasal provocation test with Rhinograph. In patients with known antigen responce, the nasal provocation test was perfor-med with the appropriate antigen disk while nasal respiratory resistance was continuously measured by Rhinograph. The dose-responce curve obtained by Rhinograph (Rhinogram) was analyzed in the case with sneeze. The values of the stable nasal respiratory resistance within one minute before and after sneeze were measured by rhinograph. Comparisons have been made between the two values. The result is as follows. 1) The nasal respiratory resistance before sneeze is higher than that after sneeze. 2) The nasal respiratory resistances are about equal both before and after sneeze. 3) The nasal respiratory resistance after sneeze is higher than that before sneeze. About half number of 1) and 2) were negative cases of the nasal provocation test. Rhinogram with sneeze is not continuous. It is difficult to analyze the uncontinuous Rhinogram. The cases with sneeze are not adequate for the nasal provocation test with Rhinograph.
