title: Changes of serum histaminase activity in pollinosis.
abstract: In order to study changes in serum histaminolytic enzyme activity in allergic individuals following allergen challenge, serum histaminase activity was measured using the 0-dianisidine peroxidase method in patients with Japanese cedar pollinosis. Significantly higher serum histaminase activity was detected in pollen season than out of season and a significant relationship was recognized between serum histaminase activity and the severity of nasal symptoms.
