1) Intradermal tests with pollen extracts of timothy, orchard grass, meadow fescue, short ragweed and red pine were carried out in 37 allergic patients with bronchial asthma (34) and allergic rhinitis (3). Positive results obtained with each pollen extract were varing from 5.5 to 24% in the allergic patients and from 0 to 14% in non-allergic subjects. (Table) 2) Positive intradermal tests were obtained with house dust extract in 56.1% of 77 patients with bronchial asthma and allergic rhinitis, while 16.4 of 73 non-allergic subjects showed positive reactions. The allergic patients were divided in two groups, namely, the group of younger age less than 30 years and that of older age more than 31 years. positive reactions to house dust extract were observed more frequently in the younger group (83.8%) than in the older group (37.8%). In the non-allergic subjects 20.4% were positive in the younger group and 13.8% in the older group with same house dust extract. (Table 2) 3) The relationship between the allergenic potency in intradermal tests and the contents of total nitrogen, protein nitrogen and polysaccharides were studied in 10 patients with bronchial asthma by use of 5 different house dust extracts. Dose-response curves of each extract, namely, the mean values of diameters of erythemas plotted against to A) dilutions in weight by volume B) polysaccharides contents C) protein nitrogen contents and D) total nitrogen contents, were shown. The allergenic potencies were widely different in each extract and could not be corrected by chemical measures.
