The Eosinophilic Changes in Rhinorrhea due to Nasal Allergy

ABSTRACT

Since the early part of the twentieth century, many authors have claimed that eosinophilia is found in the nasal secretions and blood of patients with allergic diseases. This observation has now become an established fact, and recent evidence based on extensive investigation, suggests that the eosinophil may play an active role in allergic disease. Thus, we report changes in nasal eosinophils in a group of nasal allergy patients treated by specific hyposensitization. The following results were obtained; 1. Eosinophilia was noted in 52.8 percent of untreated nasal allergy patients. 2. The eosinophilic count was gradually decreased with increasing S.D.V.(specific desensitizing vaccine) hyposensitization.
