| Research Abstract |
In Toyama and the adjacency prefectures, an epidemiological study was carried out in order to clarify causal factors of the high pollinosis morbidity. By a questionnaire survey, distribution of the prevalence of allergic symptoms was analyzed among 999 persons of 437 households. The highest prevalence was obtained at thirties of age for both sexes. The distribution of positive IgE antibody to Japanese cedar showed same distribution as that of tbe pollinosis.
Although we tried to measure airborne dust (PM10, PM2.5) using a personal sampler, it was found to be difficult to measure simultaneously a large number of samples to show regional differences.
It was also clarified that the regional cedar forests were important pollen sources to induce high pollinnosis by the vegetation survey. However further study would be necessary on the pollen-dispersion modeling to explain the local distribution of the pollinosis more precisely.
By the diet survey of families, a significant association was obtained between the oils intake and the prevalence of pollinosis. It was interesting to know that the pollinosis prevalence of males was diminished by the usage of the safflower oil in seasonal dishes. This result suggests that the life style change in eating habits can prevent the pollinosis through unknown mechanism.
