Abstract
We studied the effect of hyposensitization therapy in 26 cases with Japanease Cedar pollinosis by means of questionaires. Air distributions of the pollens throughout the year were studied for the last 7 years.
The number of the pollens were counted on a 10 mm×10 mm size slide glass e very day.
The results were as follows.
1) Clinical symptoms improved more prominently in the order of nasal obstruction, attack of sneezing, and watery rhinorrhea.
2) The rate of overall improvement was 63.9% for subjective complaints ueder this hyposensitization therapy.
3) Skin test threshold and values of total IgE and specific IgE in serum did. not decrease during the treatments but the values of RAST and RIST were recognized to show seasonal changes, and they increased in spring, and decreased in winter.
4) The number of eosinophils in nasal smear tended to decrease in treated cases more than three years. Positive rate of nasal provocation test was decreased only in cates treated for three years.
These findings showed little correlation to clinical improvement during the treatment.
