| Abstract | The serum levels of specific IgE antibodies to food allergens and inhalant allergens were evaluated in ninety five patients with bronchial asthma using the MAST system, which can measure specific IgE antibodies against sixteen different allergens with a single sample. 1. Higher positivities of specific IgE antibodies were found in inhaled allergens than in food allergens. Specific IgE antibodies against several allergens were detected in individuals more frequently in inhaled allergens than in food allergens. 2. Positivities of specific IgE antibodies against food allergens did not correlate to patients' age and patients' age at onset. In inhaled allergens, positive results in MAST system were frequently observed in patients under age of 50 and under age at onset of 60. 3. In subjects with high serum IgE levels, high positivities of specific IgE antibodies against inhaled allergens and food allergen were found. 4. The MAST system is suggested to be clinically more useful than RAST. |

| Abstract | Clinical features of asthma patients with a low % FVC (<75%) were studied in relation to clinical asthma type and disease severity. 1. The value of % FVC was not related to patient age. 2. A significant association between % FVC value and clinical asthma type was found. The value of % FVC was significantly lower in subjects with type Ⅱ asthma (bronchiolar obstruction) than in those with type Ia-1 and type Ia-2 (simple bronchoconstriction) (p<0.001). 3. % FVC value significantly correlated with disease severity. The value in the subjects tended to decrease as their asthma conditions were more severe. 4. The % FVC value in the subjects was improved after treatment (complex spa therapy). These results demonstrate that a significant correlation is present between low % FVC and disease severity in asthma patients with a low % FVC. |

| Abstract | Clinical features of asthma patients with bronchiolar obstruction (type Ⅱ asthma) were studied in relation to the proportion of neutrophils in bronchoalveolar lavage (BAL) fluid. Of 13 subjects studied, 7 were accompanied with BAL neutrophilia (53.5%) (BALn(+)) and 6 were without BAL neutrophilia (3.5%) (BALn(-)). 1. The mean age was higher in BALn(-) (66.0 years) than in BALn(+) patients (55.0 years). 2. Bronchial reactivity to methacholine was slightly higher in BALn(-) patients than in those with BALn(+). 3. The value of FEV1.0% was significantly lower in BALn(+) patints than in those with BALn(-) (p<0.01). 4. The proportion of BAL lymphocytes was signicantly more decreased in BALn(+) patients compared to the proportion in those with BALn(-) (p<0.001). 5. the values of serum IgG, IgA, and IgM were not significantly different between BALn(+) and BALn(-) patients, however, the value of IgG was more decreased in BALn(+) patients than in those with BALn(-). These results suggest that two kinds of type Ⅱ asthma ; one is with BAL neutrophilia related to suppressed immunity, and another is without BAL neutrophilia in part due to aging. |

| Abstract | Clinical significanoce of airway inflammation was assessed in 28 patients with bronchial asthma, and the results were compared with those in 9 patients with chronic obstructive bronchiolitis (COB). 1. Total cell number in bronchoalveolar lavage(BAL) fluid was markedly increased in patients with COB (51.0×10(6)), which was significantly greater than that in those with bronchial asthma (9.6×10(6) ). 2. The proportion of BAL macrophages was significantly higher in patients with bronchial asthma than in those with COB. However, the, absolute number of BAL macrophages was not significantly different between them. 3. The proportion of BAL lymphocytes was higher in patients with bronchial asthma than in those with COB, but this difference was not signifcant. In contrast, the absolute number of BAL lymphocytes was significantly greater in patients with COB than in those with bronchial asthma. 4. The proportion and the number of BAL neutrophils were markedly increased in patients with COB compared to those with bronchial asthma. 5. The proportion and the number of BAL eosinophils were higher in patients with bronchial asthma than in those with COB, although these defferences were not significant. The results suggest that airway inflammation in bronchial asthma is not so intensive as that in COB. |

| Abstract | Influence of long-term clgarette smoking on the paphophysiological changes of the disease was compared between younger and older patients with asthma. 1. The frequency of positive RAST score against inhalant allergens was significantly higher in ex-smokers than in never-smokers in older patients with astham, but not in younger subjects. 2. Ventilatory parameters such as % FVC and FEV 1.0% were not sig-nificantly different between ex-smokers and never-smokers either in younger or older patients, although a significant difference in these values was observed between younger and older subjects. 3. The % DLco was significantly lower in ex-smokers than in never-smokers both in yonger and older patients. 4. The parameters associated with hyperinflation asuch as % RV and % LAA of the lungs on HRCT were significantly higher in older patients than in younger subjects, and also significantly larger in ex-smokers than in never-smokers in older patients, but % RV was not different between ex-smokers and never-smokers in young subjects. 5. Bronchial hyperresponsiveness (BH) was significantly more increased in ex-smokers than in never-smokers in older patients, but not in younger subjects. There was a significant difference in BH be-tween younger and older patients. 6. LTB4 generation was significantly larger in ex-smokers than in never-smokers in older patients, and LTC4 generation was more in-creased in ex-smokers both in younger and older subjects. The results show that significant differences between ex-smokers and never-smokers were observed in % DLco, LTC4 generation and % LAA both in younger and older subjects, and in IgE an-tibodies production, % RV, BH and LTB4 generation only in older subjects. In contrast, the values of % FVC and FEV1.0% were not different between ex-smokers and never-smok-ers either in younger or older subjects. A significant difference between younger and older subjects was found in all other parameters except % DLco and LTC4 generation. |

| Abstract | Efficacy of complex spa therapy was studied in 55 patients with bronchial asthma. Complex spa therapy was effective in 47 (85.5%) of the 55 patients with bronchial asthma : marked efficacy was observed in 15 (27.3%), moderate in 32 (58.2%), slight in 6 (10.9%) and no efficacy in 2 patients (3.6%). Improvement of clinical symptoms and findings by complex spa therapy was more clearly observed in patients with an increased proportion of BAL lymphocytes, neutrophils and eosinophils. These findings suggest that complex spa therapy more affects cell infiltration in the airways than bronchoconstriction induced by chemical mediators. Improvement of ventilatory function represented by FEV1.0% value was higher in patients with a low proportion of BAL neutrophils, suggesting that patients with increased number of BAL neutrophils require longer complex spa therapy than those without BAL neutrophilia. |

| Abstract | Extent of nasal and maxillary mucosa lesion was estimated in 26 asthmatics using computed tomographic scan in relation to clinical features of the disease. 1. No significant differences were present in nasal mucosal thickening between atopic and non-atopic subjects. No significant differences were also present in occupancy rate of mucosa in maxillary sinuses between the two asthma types. 2. Nasal mucosal thickening was not significant different between subjects with steroid-dependent intractable asthma (SDIA) and those without SDIA. Maxillary mucosal lesions were more extensive in subjects with SDIA than in those without SOIA. However, no significant differences were observed in occupancy rate between the two types. 3. No significant differences were observed in nasal mucosal thickenings between in subjects with and without aspirin-induced asthma (AlA). Although maxillary mucosa lesion in subjects with AlA was more extensive than that in those without AlA, the differences was not significant. 4. There was not any correlation between nasal mucosal thickening and amount of expectoration per day. However, significant differences were observed in maxillary sinus lesion between subjects with less amount (<50mℓ/day) and those with large amount of expectoration (100mℓ/day≦)(p<0.002), and between subjects with moderate amount (50-99mℓ/ day) and those with large amount of expectoration (p<0.002). The results might suggest that in asthmatics with large amount of expectoration, sinus diseases affect pathophysiology of asthma, and asthmatics with large amount of expectoration should have therapy for sinus disease to improve asthmatic status. |

| Abstract | Clinical features of asthmatics with a low % FVC (<80%) were studied in relation to airway inflammation and clinical asthma types. 1. Twenty four (75.0%) of the 32 subjects with a low % FVC had steroid-dependent intractable asthma. 2. A significant association between % FVC value and clinical asthma type was found. The value of % FVC was significantly lower in subjects with type II asthma (bronchiolar obstruction), in which significantly decreased proportion of lymphocytes,and significantly increased proportion of neutrophils in bronchoalveolar lavage (BAL) fluid were observed, than in those with type la-1 (simple bronchoconstriction) with (P<0.001) and without glucocorticoid therapy (P<0.02). 3. The % FVC value was significantly improved after treatment in type lb (hypersecretion) with BAL eosinophilia, but not in those with type II with BAL neutrophilia. These results demonstrate that marked decrease of % FVC in patients with asthma correlated with airway inflammation, and that airway reversibility by medication is very low in patients with type II asthma. |

| Abstract | The correlation between the efficacy of 4-weeks administration with pranlukast, leukotriene receptor antagonist, and LTs generation by peripheral leukocytes were evaluated in 18 patients with mild-persistent asthma. The efficacy of pranlukast administration was assessed by symptom, morning PEF and pulmonary function. Pranlukast were effective in 12/18(67%) patients. In those patients, LTC4 generation before pranlukast administration was significantly high, compared with that in pranlukast-ineffective patients. LTC4 generation decreased after 4-weeks administration with pranlukast in effective patients. In ineffective patients, however, LTC4 generation increased after 4-weeks administration. LTB4 had shown no significant difference between effective and ineffective patients before administration, and LTB4 decreased after 4-weeks in both groups. Proport ion of peripheral eosinophi Is in effective patients were higher than that in ineffective patients, however not significant. After 4-weeks, proportion of eosinophi Is was decreased in effective patients and increased in ineffective patients. These findings suggest that pranlukast is effective for patients with high LTC4 generation and has the effect to suppress the accumulation of eosinophils in such patients. |

| Abstract | The maximal percent low attenuation area < -950 HU (% LAA) among three anatomic lung levels on high resolution computed tomography (HRCT) was examined in patients with asthma, classified by the degree of % LAA, in relation to the mean CT number, % FVC of the predicted value, and FEV 1/FVC (FEV1%). 1 . The mean CT number was closely related to the degree of % LAA of the lungs. The mean CT number was significantly lower in patients with high % LAA (mean CT number-915.3HU, % LAA 37.6%) than in those with low % LAA (-852.9HU, 4.7%). 2. The FEV1% value was significantly lower in patients with high % LAA (47.8%) than in those with low % LAA (62.2%)(p<0.05). The % FVC value was also significantly lower in patients with high % LAA (77.1%) compared to the value in those with low % LAA (101.2%). The results suggest that a large volume of LAA<-950HU of the lungs can be observed in patients with asthma, and the % LAA is closely correlated with mean CT number and the values of FEV1% and % FVC. |

| Abstract | The influence of smoking on pulmonary function and emphysematous changes of the lung (percentage of attenuation area < -950 HU (% LAA) on high resolution computed tomography (HRCT) was examined in 49 patients with bronchial asthma. 1. In patients with asthma, the % residual volume (RV) in many nonsmokers was less than 129%, in contrast, the % RV in many smokers was between 130% and 189% , which was higher than that in nonsmokers. 2. Significant correlations between % RV and 96LAA value, and between % RV and CT number were observed both in nonsmokers and smokers with asthma, in which as % RV more increased, % LAA value was larger, and CT number was lower. 3. % DLco value was lower in smoking patients with asthma, whose % RV was between 130% and 189% and larger than 190% , however, the % DLco value did not change in nonsmoking patients despite of higher valure in % RV. 4. A significant correlation was also observed between % FEV1.0 value and % RV both in smoking and nonsmoking patients with asthma; as % RV value more increased, % FEV1.0 value was lower. 5. Any correlation between % FVC value and % RV was not observed. These results suggest that smoking affects the % LAA of the lung on HRCT and % DLco in patients with asthma. |

| Abstract | In previous studies, we have demonstrated that chronic administration of systemic glucocorticoids decreases cortical bone mineral density (BMD), cortical bone volume, bone strength, and induces development of pathologic fractures in asthmatic patients. We have also demonstrated that glucocorticoid administration appears to be responsible for the process of cortical bone porosity at both endosteal and intracortical sites in postmenopausal asthmatic patients. There is a difference of gonadal hormones between male and female. To investigate the influence of hormonal difference on glucocorticoid-induced cortical bone porosity, we studied cortical bone volume and BMD in both male and female patients with asthma in this report. A total of 99 asthmatic patients (male 26 cases, female 73 cases) were enrolled in the study. Peripheral quantitative computed tomography (pQCT) was used to measure cortical BMD and relative cortical volume. The cortical volume-density relationship appeared to remain constant regardless of the level of systemic glucocorticoid administration, age or sex, suggesting cortical bone porosity causes similar and simultaneous decreases in cortical bone volume and density. In conclusion, glucocorticoid administration appears to be responsible for the process of cortical bone porosity at both endosteal and intracortical sites despite the gonadal hormonal differences. |

| Abstract | Costs of drugs used for the treatment for 1 year were examined in 32 pa-tients with asthma in relation to disease severity. Asthma severity was classified as : 1) intermiitent; 2) mild persistent; 3) moderate persistent; 4) severe persistent. 1. The total cost of drugs used for each patient for 1 year was the highest (￥263,710) in patients of stage 4 (severe persistent) and the lowest (￥74,670) in those of stage 1 (intermittent). The costs of bronchodilators and antiallergics were predominant at all stages, and their cost increased significantly with increasing severity. 2. The costs of drugs such as antiallergics and bronchodilators were predominant, and the costs of drugs such as inhaled corticosteroids and mucolytics were considerably high in pa-tients of all stages. 3. The costs of bronchodilators, inhaled corticosteroids, and antiallergics were the largest in patients of stage 4. The results suggested that the costs of durgs used for the asthma treatment tended to increase as the disease sever-ity became stronger from stage 1 to stage 4, and the maln drugs related to the in-crease in total costs were bronchodilators, antiallergics, and inhaled corticosteroids. |

| Abstract | Histamine release from bronchoalveolar cells induced by house dust mite (HDm) was compared in patients with atopic asthma sensitive to HDm in relation to age. 1. Total cell number in bronchoalveolar lavage (BAL) fluid was larger in patients over the age of 40 years (9.10×10(6)) than in those aged between 20 and 39 years (6.25×10(6)), however, this was not significant. 2. Number of BAL eosinophils was not significantly different between the two age groups. 3. Number of BAL basophilic cells was significantly higher in younger patients (20-39 years) (1.85±1.03×10(2)/mℓ) than in older patients (40+ years) (0.39±0.24×10(2)/mℓ) (p<0.001). 4. Histamine release from BAL cells induced by HDm was significantly higher in younger patients (38.1±24.8%) than in older patients (0%) (p<0.001). These results suggest that histamine release from BAL cells in patients with HDm allergy decreases with aging. |

| Abstract | Clinical risk factors associated with the development of osteoporosis and vertebral fractures were evaluated in patients with asthma in relation to sex, age, and dose of glucocorticoids (GC). In 75 asthmatic patients including 44 steroid-dependent asthma, the bone mineral density (BMD) of the lumber spines was measured by quantitative computed tomography (QCT). Thirty five patients of them were followed up with radiographs over a period of 0.5 to 4 years (average: 2.6±1.3 years). The BMD was significantly lower in older (p |

| Abstract | In recent years, it has been noted that there is a close correlation between leukotrienes and late asthmatic reaction (LAR). In this study, effects of dietary supplementation with perilla seed oil rich in alpha-linolenic acid, which is speculated to affect the generation of leukotrienes through metabolism of arachidonic acid (AA), were evaluated in 6 patients with asthma. The symptoms and ventilatory function were improved after 2-week dietary supplementation with perilla seed oil. The generation of LTB4 and LTC4 by peripheral leucocytes stimulated with Ca ionophore A23187 was significantly suppressed by the dietary supplementation (LTB4 and LTC4 ; p<0.05). Regarding the composition of fatty acids in serum phospholipids, the concentrations of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and AA tended to increase after the supplementation, accompanied with an increase in the ratio of EPA to AA. These results suggest that dietary supplementation with perilla seed oil brings beneficial effects in the treatment of asthma. |

| Abstract | The low attenuation area (LAA) of the lungs on high resolution computed tomography (HRCT) was evaluated in 20 asthmatics (10 ex-smokers and 10 never-smokers) and 10 patients with pulmonary emphysema (all ex-smokers) by ventilatory function, lung volume, DLco, and a ratio of expiratory LAA/inspiratory LAA. 1 . The % LAA of the lungs on HRCT was significantly larger in patients with pulmonary emphysema(PE) than in those with asthma, but there was not significant difference in % LAA between ex-smokers and never-smokers of asthmatics. 2. A ratio of expiratory Winspiratory LAA was significantly higher in patients with PE than in those with asthma , and the ratio was significantly higher in ex-smokers of asthmatics than in never-smokers (p<0.05). 3 . The difference in % residual volume and % DLco was significant between asthma and PE , and between ex - smokers and never-smokers of asthmatics (% RV : p<0.05, DLco : p<0.05) . 4 . The difference in the values of % FVC, % FEV(1) .O, and FEV1.0% was significant between asthma and PE, but not significant between ex-smokers and never- smokers of asthmatics. The results suggest that the difference in a ratio of expiratory W inspiratory LAA, % RV and % DLco was significant between ex - smokers and never - smokers of asthmatics , and cigarette smoking induces more irreversible changes of the lungs. |

| Abstract | We examined histamine release and morphological changes in basophilic granulocytes from atopic subjects, in response to stimulation with antigen and Ca ionophore A23187. 1. Histamine release and a reduction in the rumber of basophils were more rapid and greater in extent at an early stage of antigen stimulation compared with Ca ionophore A23187 stimulation. 2. Morphological changes in basophils, represented by increased motility, in terms of an increased ratio of short to long axis diameter (L/S ratio), as well as the increased frequency of basophils with localized granules and those with pseudopods, were more often observed antigen stimulation than with Ca ionophore A23187 stimulation. In contrast, morphogical changes in which basophils appeared swollen, showing an increased mean cell diameter and an increased frequency of cells with 5 vacuoles or more were more predominant with Ca ionophore A23187 than with antigen stimulation. The results obtained here show that bridging of IgE receptors is essential to activate basophils and induce increased motility in these cells. |
