ABSTRACT
The tissue kallikrein level in the nasal wash was measured before and after 4-week administration of oxatomide (30 mg per day) in 9 patients with perennial allergy. It was found that tissue kallikrein level in the nasal wash obtained following provocation tests significantly decreased from 6.05 +/- 4.43 (10(-10) mol/hour/L) to 1.84 +/- 0.93 (10(-10) mol/hour/L) after the administration of oxatomide. Improvement in subjective symptoms was also observed in all patients after the administration. These results would indicate that kinin in the system is actively involved in the pathogenesis of nasal allergy.

An immunohistochemical study was made on the degree of activated eosinophil (EG2) infiltration in the inferior turbinate of 20 cases of perennial allergic rhinitis who underwent septal reconstruction and bilateral inferior turbinectomy approximately 5 months after the unilateral application of trichloroacetic acid (TCA). The distribution of EG2 was also evaluated in nasal smears obtained from the same subjects, and a comparison was made between TCA-applied and nonapplied sides. It was found that the number of EG2 was significantly decreased in the TCA-applied side. It was assumed that TCA application successfully suppressed reagin-dependent allergic reaction in the tissues.
