| Abstract | Body Surface Temperature was observed by thermography. The surface temperature of a healthy person's lower limbs, after being cooled in a water bath, increased in parallel with time. Patients with Diabetes Mellitus had different patterns in the rate of increase of the surface temperature. After cold loading, one patient had a 99% recovery ratio of surface temperature, the same level as healthy volunteers (83%, and 88%), as calculated by a picture processing program with the computerized thermotracer. However, the recovery ratio of other patients was poorer, ranging from 56% to under 6% recovery. This measurement of elevation of body temperature is useful for the estimation of peripheral blood flow in patients with lower limbcirculation failure. |

| Abstract | The body surface temperature of 41 patients suffering coldness, numbness or pain in their feet was examined using thermography. Thermographic results were analyzed quantitatively by calculating a recovery ratio as: Recovery ratio =[Total counts of thermography (Pixels) over temperature (T) after cold loading] ÷ [Initial counts over T before cold loading] x 100(%). Three different baseline temperatures, 26℃. 27℃ and 28℃, were used in processing the thermographic results into pictures. The recovery ratio was susceptible to temperature, and we recommend a baseline temperature limitation of 27℃ for clinical study. A bi-modal distribution of recovery ratio was observed in 18 patients with diabetes mellitus. One group (6 subjects) had high recovery ratio between 80%-100%, and another group (10 subjects) had a low recovery ratio between 0%-19%. The results of thermography were also influenced by weather. To reduce the effect of outside temperature, we used pre-loading with hot water at 36℃ for 5 min (hot loading). A large difference in recovery ratio between presence and absence of hot loading was observed in 6 of the 30 subjects. The difference was over-estimated in more than 20% of recovery ratio without hot loading as compared with hot loading in these 6 subjects. The effect of drugs on peripheral circulation, such as beraprost sodium and sarpogrelate hydrochloride, was clear and quantified using thermography under these conditions of hot loading. |

| Abstract | Rhinitis frequently precedes asthma, and treating allergic rhinitis has benefi-cial effects on asthma, suggesting upper airway disease ia a risk factor for asthma. The aim of the present study was to investigate the influence of allergic rhinitis on se-rum IgE level, leukotriene generation by peripheral leukocytes, and bronchial hyperresponsiveness (BHR) to methacholine in patients with atopic asthma. Seventy-one asthmatic subjects (mean age, 59.5±12.5, years ; 37 women, 34 men) were recruited, and 48 asthmatics had allergic rhinitis and 23 asthmatics did not have allergic rhinitis. The log10 (Dmin) was significantly lower for those with allergic rhinitis than those with-out allergic rhinitis (P<0.05), implying that those with allergic rhinitis developed BHR to a greater degree than those without allergic rhinitis. LTC4 generation from periph-eral leukocytes was significantly greater for atopic astmatics with allergic rhinitis than those without allergic rhinitis (p<0.05). In contrast, the amount of LTB4 produced from peripheral leukocytes did not significantly differ between asthmatic patients with and without allergic rhinitis. These results suggest that the presence of allergic rhinitis enhances BHR by enhancing LTC4 production. while the presence of allergic rhinitis did not affect LTB4 production in patients with atopic asthma. |

| Abstract | Our previous studies have shown that subjective symptoms and ventilatory function are improved by spa therapy in patients with chronic obstructive pulmonary disease (COPD). In the present study, we investigated the effects of spa therapy on six-minute walk distance in patients with COPD . Subjects were 10 patients with chronic obstructive pulmonary disease (9 males and 1 female) admitted to our hospital to undergo pulmonary rehabilitation. All patients had complex spa therapy (swimming training in a hot spring pool, inhalation of iodine salt solution, and fango therapy) for 4 weeks. Ventilatory function, six-minute walk distance, oxygen saturation and Borg scale were measured. Vital capacity, forced expiratory volume in one second, sixminute walk distance and oxygen saturation increased, but not significantly. Significant decreases were observed for Borg scale. We found that spa therapy improved ventilatory dysfunction and six-minute walk distance in patients with COPD. The results demonstrated that spa therapy may lead to better disease control and exercise tolerance in patients with COPD. |

| Abstract | Costs of drugs used for the treatment for 1 year were compared before and after spa therapy in 16 patients with asthma in relation to disease severity. Asthma severity was classified as : stage 1 (intermittent), 2 (mild persistent), 3(moderate persistent), and 4(severe persistent). 1. The total cost of drugs used for each pa-tient for 1 year clearty decreased in all groups. The % decrease of the costs of drugs in each group was 27.2% in patients with stage 1, 43.5% in those with stage 2 and 34.1% in those with stage 3-4 (mean 34.5% ). The reduction of the cost of bronchodilators was predominant in patients with stage 3-4, and the decrease in the cost of corticosteroids predominant in those with stage 2. The reduction of costs of antiallertgics, mucolytics, and antibiotics was predominant in patients with stage 2 and stage 3-4. The % reduction in the cost of corticostroids was remarkable in patients with stage 2. The % decrease in the costs of mucolytics and antibiotics was predomi-nant in patients with stage 2 and stage 3-4. The results obtained here suggest that the costs of drugs used for asthmatics could be reduced by long-term spa therapy, and the reduction of the costs was larger as asthma stage became more severe. |

| Abstract | N-3 fatty acids are reportedly effective for asthma. In addition, spa therapy has been reported to be effective for patients with asthma. In the present study, the effects of spa therapy combined with perilla seed oil- rich diet (rich in n-3 fatty acid)were examined on asthma. A total of 14 asthmatic patients had a complex spa therapy and consumed a perilla seed oil- rich diet - rich in a -linolenic acid (alpha-LNA) for 8 weeks. Generation of leukotriene (LT) C4 by leucocytes, respiratory function were analyzed. The generation of LTC4 by leucocytes decreased significantly for 2, 4 and 8 weeks (P |

| Abstract | N-3 fatty acids have been reported to be effective for asthma. In the present study, the effects of perilla seed oil (n-3 fatty acids) on asthma were compared with the effects of corn oil (n-6 fatty acids) in terms of pulmonary function, lipometabolism and the generation of leukotriene C4 (LTC4) by leucocytes. A total of 28 asthmatic patients were randomly divided into two groups : Group A patients (15 subjects) consumed perilla seed oil-rich supplementation, while Group B patients (13 subjects) consumed corn oil-rich supplementation for 4 weeks. Generation of LTC4 by leucocytes, respiratory function and the serum levels of lipids were compared between the two groups. The generation of LTC4 by leucocytes decreased significantly in Group A subjects following perilla seed oil-rich supplementation for 2(P < 0.05) and 4 weeks(P < 0.01). A significant difference in the generation of LTC4 was observed between the two groups after different dietary supplementations for 4 weeks (P < 0.05). Significantly increased values for PEF (P < 0.01), FVC (P < 0.05) and FEV1.0 (P < 0.05) were found in Group A subjects following perilla seed oil supplementation for 4 weeks, compared with the initial value prior to supplementation. A significant decrease in the serum level of total cholesterol, LDL-cholesterol and phospholipid was detected in Group A subjects following perilla seed oil supplementation for 4 weeks. The present results suggest that peril la seed oil-rich supplementation is effective in the treatment of asthma in terms of its ability to suppress LTC4 generat ion by leucocytes, and in inducing an improvement in pulmonary function associated with changes in the serum level of lipids. |

| Abstract | The influence of cigarette smoking on the pathophysiology of asthma in the elderly remains controversial. In this study, the inluence of cigarette smoking on IgE - mediated allergy including the generation of leukotrienes B4 (LTB4) and C4 (LTC4) was examined in forty asthmatics over the age of 70 years (20 ex-smokers and 20 never-smokers), and 20 patients with pulmonary emphysema over age 70 (all ex - smokers). The frequency of patients with serum IgE more than 200 IU/ml was significantly larger in smoking asthmatics than in non - smoking asthmatics. The incidence of patients with positive RAST score for inhalant allergens, was also significantly higher in patients with a history of smoking than in those without a smoking history. There were no significant differences in the frequency of patients with positive RAST and those with serum IgE more than 200 IU/ml between non-smoking asthmatics and patients with pulmonary emphysema. The generation of leukotriene B4 (LTB4) by leukocytes was significantly more increased in ex-smokers than in never-smokers in the elderly asthmatics. The results suggest the possibility that cigarette smoking enhances IgE - mediated allergy in elderly patients with asthma. |

| Abstract | Dietary sources of a -linolenic acid, such as perilla seed oil, may have the capacity to inhibit the generation of leukotrienes (LTs) by leucocytes in patients with
asthma, as has been reported with the consumption of other long - chain n- 3 fatty a-cids.
The factors affecting the suppression of leukotriene (LT) C4 generation by leucocytes were examined by comparing the clinical features of patients with asthma who had been given dietary perilla seed oil (n - 3 fatty acids). Group A consisted of patients in whom the leucocyte generation of dietary perilla seed oil LTC4 was suppressed by this procedure. Group B consisted of those in whom LTC4 generation was not suppressed. LTC4 generation by leucocytes significantly decreased in group A for two (P<0.05) and four weeks (P |

| Abstract | The influence of aging on the pathophysiology of asthma in the elderly was examined in 40 patients (20 younger asthmatics under the age of 50 years, mean age 32.5 years and 20 elderly asthmatics over the age of 70 years, mean age 74.3 years), relating to IgE - mediated allergy, pulmonary function, low attenuation area (LAA) of the lungs on HRCT, and the generation of leukotrienes B4 (LTB4) and C4 (LTC4) by leukocytes. The frequency of patients with serum IgE of more than 200 IU/ml, and the incidence of those with a positive RAST score for inhalant allergens were significantly higher in younger patients than in elderly subjects. The values of % FVC, % FEV1 and FEV 1% were significantly larger in younger patients compared with elderly subjects. The % RV was significantly larger in elderly patients than in younger patients, however, the difference in % DLco was not significant between the two age groups. The LAA of the lungs on HRCT and the ratio of expiratory LAA (exp LAA) to inspiratory LAA (ins LAA) were also significantly larger in elderly asthmatics than in younger subjects. The generation of LTB4 and LTC4 was larger in younger patients than in elderly subjects, and LTB4 generation was significantly larger in younger subjects compared with elderly subjects. These results suggest that changes in IgE-mediated allergy, airflow and lung volume accompanied with hyperinflation are often observed in elderly asthmatics. |

| Abstract | Effects of aging and glucocorticoid therapy on bronchoalveolar lavage (BAL) cells, particularly lymphocytes, neutrophils and eosinophils, were examined in 81 patients with asthma. 1. The proportion of BAL lymphocytes tended to increase with aging in asthmatics under age 69 years, and the proportion was significantly higher in patients with asthma between the ages of 60 and 69 than in those under age 39 and between the ages of 40 and 49. 2. The proportions of BAL neutrophils and eosinophils were not related to aging. 3. The proportion of BAL lymphocytes was higher in patients without glucocorticoid therapy than in those with steroid-dependent intractable asthma (SOIA) in those under age 69 years. In patients between the ages of 50 and 59, the proportion of BAL lymphocytes was significantly higher in patients without glucocorticoids than in those with SOIA. 4. The proportion of BAL neutrophils was higher in patients without glucocorticoid therapy than in those with SOIA, and the difference was significant in patients between the ages of 60 and 69. 5. The proportion of BAL eosinophils was not related to glucocorticoid therapy. These results suggest that the proportion of BAL lymphocytes and neutrophils is affected by aging and glucocorticoid therapy, but not BAL eosinophils. |

| Abstract | The purpose of this study is the effect of partial cold-loading on whole body peripheral circulation. The body surface peripheral circulation in 24 cases (25 years old to 86 years old, the average was 64.3 years) who were suffering coldness, numbness or pain in their feet was examined using Laser-Doppler blood flowmetry. The peripheral circulation at the base of the 2nd toe of the right foot was estimated after the foot was submerged and cooled for 5 min in a water bath at 20°C (i. e. cold-loading). At the same time, the distant body surface peripheral circulation was estimated at the base of the 2nd finger of the right hand. Simultaneous observations were made of blood flow, blood mass and blood velocity. The peripheral blood flow of the upper limbs at a room temperature of 20°C (pre-loading) was 5.00 ml/min 100 9 tissue on average. The average blood rnass was 287 and the average blood velocity was 0.516. On the other hand, the average peripheral blood flow of the lower limbs was 2.23, the average blood mass was 149 and the average blood velocity was 0.574. This result shows that the blood flow and blood mass of the upper limbs were more than in the lower limbs. The average blood flow at the upper limbs decreased to 3.69 from 5.00 (or at 26.2% ) when the lower limbs were submerged and cooled for 5 min in a water bath at 20°C (i. e. cold-loading). On the other hand, blood flow of the lower limb was 1.51 m l under a condition of cold-loading, and decreased 32.3% from 2.23. Blood mass of the upper limb was 241 on average and decreased 16.0% from 287. Blood mass of the lower limb was 113 on average and decreased 24.2% from 149. There was no difference between blood velocity of the upper limb under the conditions of room temperature at 20°C (0.516) and cold-loading (0.501). However, blood velocity of the lower limb increased to 0.642 from 0.574. After the end of cold loading, there was some tendency for blood flow, blood rnass and blood velocity to return to the amount at pre-loading. Twenty minutes after the end of cold-loading, blood flow increased to 5.74 (14.8% ) compared with pre-loading (5.00). However, blood flow of the lower limb remained at only 83.9% (1.87) of the amount at pre-loading (2.23). These results show that partial cold-loading of the lower limb had a quantitative effect on the distant peripheral circulation. The speculated mechanism of this phenomenon is that it to protects against loosing body heat from the body surface under the conditions of local cold-loading. Our body has defense mechanisms to decrease whole body peripheral circulation to protect against loosing body heat. |

| Abstract | Concentrations of main bronchoconstricting chemical mediators, histamine and leukotriene C4 (LTC4), were measured in bronchoalveolar lavage (BAL) fluid, and when cells (peripheral leukocytes and BAL cells) were stimulated by Ca ionophore A23187, in 7 atopic and 7 nonatopic asthma patients. 1. The proportion of basophilic cells was significantly larger in atopic than in nonatopic asthma (p<0.05), however no significant difference was present in the other BAL cells between the two asthma types. 2. Concentration of histamine in BAL fluid was significantly higher in atopic than that in nonatopic asthma, however, difference in that of LTC4 was not found between them. 4. The release of LTC 4 from BAL cells was higher in nonatopic than that in atopic asthma, but this was not significant. In contrast, the release of histamine was significantly higher in atopic compared to that in nonatopic asthma (p<0.001) when the cells were stimulated by Ca ionophore A23187. These results suggest that both histamine and LTC4 participate in the onset mechanism of atopic asthma, and only LTC4 in that of nonatopic asthma. |

| Abstract | Ventilatory function and inflammatory cells in airways were compared between patients with type Ⅱ (bronchiolar obstruction) asthma and those with obstructive bronchiolitis. 1. Age and age at onset were higher in patients with type Ⅱ asthma than in those with obstructive bronchiolitis. IgE-mediated allergic reaction was observed in patients with type Ⅱ asthma, but not in those with obstructive bronchiolitis. 2. In ventilatory function tests, all ventilatory parameters examined were lower in patients with type Ⅱ asthma compared to those with obstructive bronchiolitis, and the differences were significant in FEV1.0% (p<0.001), % MMF (p<0.02), and V50 (p<0.01). 3. The proportion of BAL neutrophils was very high in type Ⅱ asthma (55.7%) and obstructive bronchiolitis (74.4%), however, this was not significant. 4. Absolute numbers/BAL fluid of total cells, BAL macrophages and BAL neutrophils were significantly higher in patients with obstructive bronchiolitis than in those with type Ⅱ asthma. 5. The results on absolute number/mℓ of BAL cells demonstrated that number of BAL neutrophils markedly larger in patients with obstructive bronchiolitis compared to those with type Ⅱ asthma. These results show that high proportion of BAL neutrophils was observed in the two respiratory diseases, however, the degree of inflammation in airways was markedly greater in obstructive bronchiolitis. |

| 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 | 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 | 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 | 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 | 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. |
