[Value of histocytological examinations of the nasal mucosa in pollinosis].
Cytogramme analyses have been made on the nasal mucosae of 100 patients affected with pollinosis. Ten of the cases had a histocytological examination during the season and also during winter. In the period of symptom upsurge neutrophil cytogrammes were seen in 31% of patients, 30% had eosinophils and the remainder had eosinophils and neutrophils. Basophils were seen in the cytogrammes from 38 patients (mean 4 to 15%). In those patients where the cytogrammes were eosinophils and neutrophils and the titre of basophils was below 15%, Lomusol, Beconase and hyposensitisation were found to be effective, in contrast to those in whom the cytogrammes had more than 70% of eosinophils or more than 15% basophils.
