JOURNAL FREE ACCESSChina is one of the earliest countries to realize the allergy disease. More than 2000 years ago, there were recordes of nasal allergy and asthma in the Chinese traditional medical works. While in the recent period of China, it was a little later to undertake the clinic and reseach of nasal allergy. In 1939, the first allergy clinic was set up in the affiliated hospital of Peiking Union Medical College. From 1956, the reaseach of nasal allergy was begun. In 1964, the typical cases of pollinosis were reported in the first time and the artemisia pollen was affirmed to be the main allergenic pollen in China, esp. in north China. In 1970's-1980's, some prevlence survey of pollinosis was carried out in parts of north China in succession. From 1984 to 1989, a national survey of airborne and allergenic pollen was firstly fulfilled in China.
To explore the incidence of nasall allergy in mordon China, the author began a prevalence survey on nasal allergy in the students in Jiangsu Province from 1995. The first investigation suggested the positive rate of the scratch test and the prevalence rate of nasal allergy in China were lower than those in Japan. Whereas, because of the wide territory of China, the result of only one time and one region must not represent the overall distribution of the disease, we will select other investigating spot and make on-the-spot investigation in all over the country on a large scale.View full abstractDownload PDF (23395K) -

JOURNAL FREE ACCESSChanges in the positive rate of a scratch test with aging were examined in the same students who all underwent a collective physical exmination and a relevant scratch test in the years of 1989, 1990; 1992, 1993 and 1995, 1996 in Shiraoicho, Hokkaido. The subjects consisted of first graders at an elementary school in 1989, 1990 who were then in the fourth grade in 1992, 1993, and in the first yeat of junior high school in 1995, 1996. The comparison of scratch test results in the years of 1989, 1990; 1992, 1993; and 1995, 1996 in the same groups of students showed that the positive rate increased significantly. The increase in the positive rate of the scratch test as the students aged is considered to be due to the duration of the period during which the students were exposed to the allergen. Main allergen, house dust and mite, are increasing recently in Japanese houses. That increased also the duration and period of exposure to the students.View full abstractDownload PDF (12491K) -

JOURNAL FREE ACCESSWe began a prevalence survey on nasal allergy besides Japan from 1995. The objects were the first and fourth years students in Nanjing Medical University, China. The same investigation was done in 1996.
1. The total number of the objects in 1995 and 1996 was 863 (M 543, F 320). The prevalence was 1.0% and the rate of positive symptons was 2.6%. The prevalence and the rate of positive were lower than the result of the investigation (The prevalence was 4.5%, the rate of positive symptons was 12.6%) in Shiraoicho, Hokkaido, Japan.
2. The positive rate of scratch test was 39.1% of the first years students, and 41.9% of the fourth years students. The rate of positivity of the scratch test of the youth tended to increase with aging. The rate of positivity of the scratch test of the pupils in Shiraoi-cho was almost the same with that in the students in Nanjing Medical University. That showed the rate of positivity of the scratch test of the youths in China was low.View full abstractDownload PDF (7480K) -

JOURNAL FREE ACCESS1. We have inspected nasal allergy in a total of 6415 youths in Japan and China.
2. In Japan and China, the rate of sensitization to nasal allergy, that is the rate of positivity for the scratch test, tended to increase with aging.
3. In both the countries, this tendency was observed in the school children who lived in the same autonomy at the same time. In Japan, the positivity rate for the scratch test in the same subjects tended to increase with aging.
4. The increase in the positivity rate with aging of these school children may increase the duration of exposure of the school children to allergen. The sensitization assumed to increase along with prolongation of the total duration of exposure.
5. In China, however, the positivity rate for the scratch test and the prevalence rate of nasal allergy are lower than those in Japan. The economical development in China is currently in progress following Japan. The positivity rate of the scratch test and the prevalence rate of nasal allergy may also increase with the progression.View full abstractDownload PDF (38242K)
