We examined the clinical features and laboratory findings of 30 asthmatic patients with positive scratch test against extracts of orchard grass-pollen. One patient was sensitized only by grass-pollen. Others were co-sensitized by multiple antigens including mites and molds. There are no clear relations between the seasons of grass-pollens and clinical symptoms in these patients except one typical case, K. F., indicating that other antigens, such as mites and molds, play more important roles in asthma development in most patients. However, substantial numbers of patients were cosensitized by grass-pollens as shown in this paper, indicating the importance of grass-pollens as antigens of bronchial asthma, although this is concealed by the high incidence of mite-antigen positivity. The mechanism of sensitization in certain patients by only one group of antigens such as grasspollens should be further investigated.
