抄録 <p>In order to elucidate the role of erythrocyte catalase in the accumulation of mercury in erythrocytes, labeled erythrocytes and plasma were prepared by exposing normal and acatalasemic mice to radioactive mercury vapor (203Hg0: 6.8mg/m3) for 30 min. Labeled erythrocytes (or plasma) were mixed with unlabeled plasma (or erythrocytes) of normal or acatalasemic mice and incubated at 0 degrees C for 1 h. After incubation, the radioactivity of mercury in the erythrocytes and the plasma was measured by a gammascintillation counter. When labeled erythrocytes were incubated with unlabeled plasma, the ratio of mercury transferred from acatalasemic erythrocytes to normal plasma (11.6%) or to acatalasemic plasma (13.3%) were significantly higher than that from normal erythrocytes to normal plasma (1.8%) or to acatalasemic plasma (2.2%). When labeled normal (or acatalasemic) plasma was incubated with unlabeled normal or acatalasemic erythrocytes, the uptake of mercury by acatalasemic erythrocytes from normal plasma was 2.0%, and 1.2% from acatalasemic plasma, which tended to be lower than that by normal erythrocytes from normal plasma (3.4%) or from acatalasemic plasma (2.2%). The results indicated impaired accumulation of mercury in acatalasemic erythrocytes, suggesting the importance of catalase in taking up mercury in erythrocytes and protecting other organs from toxic effects of metallic mercury.</p>

抄録 <p>Maximal expiratory volume-time and flow-volume (MEVT and MEFV) curves were constructed from the measurements of young male nonsmoking, mild and moderate asthmatic patients (mean age, 29.7 yrs.). Eleven parameters of the pulmonary function tests, two MEVT, six MEFV, and three mean time constant (MTC) parameters, were calculated from the curves. These parameters were used in 15 analyses through the all possible selection procedure (APAP) discriminating between mild and moderate asthmatics. The probability of misclassification was computed with each of the eleven parameters, and all eleven probabilities thus obtained were compared with each other. This procedure showed us that the probability of misclassification ranged from 30.83% to 45.40% and that the most useful parameter was MTC50-25. The probability of misclassification computed using all eleven parameters (total parameter group) was 15.90%. The discriminant analysis indicated that the flow-volume patterns varied according the severity of bronchial asthma, thus, the flow-volume curve was considered to be important in analyzing the severity of bronchial asthma.</p>

抄録 <p>We considered upper and lower airway allergies as different phases of airway allergy and MEFV patterns to vary according to the intensity of airway obstruction in maximal expiratory flow-volume and volume-time tests on fourteen patients with nasal allergy, two with allergic bronchitis, two with bronchial asthma, and sixteen nonsmoking healthy subjects. In nasal allergy, flow changes during high lung volumes were different from those in allergic bronchitis and bronchial asthma, and MEFV patterns in nasal allergy were more widely varied than those in allergic bronchitis and bronchial asthma. We classified MEFV patterns into five ones.</p>

抄録 <p>Pulmonary function tests were performed on 252 healthy young subjects free from respiratory and allergic symptoms, and 80 young subjects with past history of nasal allergy (PNA) and 10 subjects with past history of bronchial asthma (PBA). All the subjects were non-smokers. Maximal expiratory flow-volume (MEFV) curves were visually classified into five types (A-E). The percent distribution of type A in healthy subjects was significantly higher than in the PNA group, while the total sum of percentage of types B, C, and D in the PNA group was significantly higher than in the healthy subjects. The percent distribution of type E in the PNA group was similar to that in the healthy subjects. The percent distribution of MEFV types were significantly different between healthy males and healthy females. The percent distribution of types A, B and E were the highest in healthy subjects, PNA and PBA groups, respectively. Conclusively, the difference in the percent distributions of MEFV types was recognized among healthy subjects, PNA and PBA groups.</p>
