Abstract
|
|
|
The air-borne fungi are possible causative factors of certain allergic diseases such as a group of atopic diseases or urticaria in which Ig E is known to be involved in patho-mechanism in the process of immunological reaction of type I hypersensitivity.
In order to understand basically the allergic diseases caused by air-borne fungi among children, authors studied the fluctuation of population of air-borne fungi at monthly intervals from August through October in the classrooms of two storied-buildings of three urban primary schools in Kwang-ju city area.
The results obtained were as follows:
1. The identified fungi species with the percentage of colony counts in parentheses were Aspergillus sp. (27.2%), Hormodendrum sp. (17.9%), Penicillium sp. (16.9%), Alternaria sp. (12.4%), Mycelia sterila (10.7%), Trichoderma sp. (1.0%), Geotrichum sp. (1.0%), Fusarium´ 8p. (0.3%), and other unknown species (12. 0%) in decreasing order of frequency.
2. The monthly fluctuations of number of cultured colonies of four major air-borne fungi (Aspergillus, Hormodendrum, Penicillium, and Alternaria) were 89 in August, 129 in September, and 48 in October.
3. It was suggested that there might be a relationship among the humi dity, the temperature and the population of the air-borne fungi because the abrupt drop in August seemed to be related to high level of the humidity(86. 5 %) and the temperature (31.0°C).
4. With regards to the location of sampling, differences in the identified fungi species and the number of colony counts were not evident. Authors reviewed relevant literatures and made discussion also.
