Abstract
A survey was carried out to study allergic symptoms among 2, 135 secondary school pupils in Shanghai of China. Among them, 403 pupils were tested for the specific antibody titer of total IgE, mites. Japanese cedar trees, willow cedar trees, cypress trees amd parasites. After studying the relation between the antibody valence in blood and the symptoms, 195 pupils the largest group were found to have a positive mite antibody. Those who sneeze frequently have the highest ratio of positive mite antibody. It was found among those who sneeze frequently that 45 pupils with a positive parasite antibody also had a high possibility of positive rate. Among the subjects with positive or negative parasite antibody, those with positive mite antibody composed 91.1% of the group with a positive parasite antibody, while the negative parasite antibody group was 43.0%. On the other hand, there were only 4pupils with a positive parasite antibody who had a negative mite antibody. Among those with a positive parasite antibody, a high percentage were also carriers of a positive mite antibody In addition. Also among those with a negative parasite antibody were found to have a difference of symptoms due to the existence or non-existence of the mite antibody. With the above results, it is concluded that there is a close relation ship between symptoms of a pollen allergic person and the existence of the mite antibody. There fore, it is necessary to consider the effect of the existence of the mite antibody when studying its correlation with pollen allergies and the parasite antibody.
