Abstract
We tried intracutaneous tests, and investigated nasal secretion, esosinophilic cells of blood, and psychosomatic aspect according to the Cornell Medical Index Health Questionare concerning 84 patients with allergic rhinitis. Then selecting 6 patients who showed positive skin reaction against house dust extract only, we carried out the specific desensitization therapy.
The results obtained were as follows: 42% of the whole patients sh owed allergic heredity. As complications, urticaria and bronchialasthma were predominant. 29% suffered all the year and 20% only in winter. Mornings or the times when the temperature fell suddenly were apt to provoke nasal fit. Food had no causal relation with the fit of nasal allergy, but many patients showed positive response in the skin test by food extracts.
Positive skin reaction to house dust extract was caused more frequently than that to other allergen extracts. Eosinophile cells of nasal secretion were found in 85%. 62% showed blood eosinophilia. Psychosomatic aspect of the patients was normal. After desensitization therapy using house dust extract in 6 patients, we marked that it was remarkable effective in 2 cases, effective in other 2 cases and ineffective in the rest. However, we could not find any variation of the numbers of eosinophilic leucocyte in nasal secretion or in blood nor any reduction of skin reaction.
