The positive rates of allergen-specific IgE antibodies were examined using the MAST system for a comparison between nasal allergic patients and healthy adults in Osaka. The patient group consisted of 47 males and 52 females, while the control group had 50 males and 50 females. The age of the subjects in both groups ranged from 20 to 29 years old. For the males patients, Dermatophagoides farinae showed the highest positive rate; 51%, while Japanese cedar was 47%, and thereafter was followed by timothy grass, sweet vernal and house dust (HD). In female patients, the highest positive rate was exhibited for Japanese cedar: 46%, while D. farinae was 40%. Although the positive rates of D. farinae and HD were highest in the male group compared with the female group, no difference in either group was observed for pollen allergens. Overall, the positive rates in the patients group tended to exceed those of the control group, especally regarding pollen allergens. In addition, a significant difference in the positive rate was seen in the patient group compared with the control group. The number of positive allergens was greater in both male and the patient group. As mentioned above, males tended to be sensitized more easily than females in both the patient and healthy adults groups.
