Abstract <p>Cell-mediated immunity was examined in 45 patients with bronchial asthma by observing the delayed cutaneous reaction to purified protein derivative (PPD) and Candida albicans (C. albicans). The delayed skin reaction to PPD showed a decrease with age starting between 50 and 59 years old. The delayed reaction to PPD decreased more prominently with aging, being significantly depressed in the patients aged over 70 years than in those aged between 30 and 49 years (induration, p &#60; 0.02; flare, p &#60; 0.01). The C. albicans-induced skin reaction was significantly lower in the patients aged over 70 years than in those between 60 and 69 years old (induration, p &#60; 0.01; flare, p &#60; 0.05). The delayed skin reaction to PPD and C. albicans was significantly depressed in the patients with a serum IgE level over 1001 IU/ml. Delayed skin reaction to PPD and C. albicans was more depressed with aging and an elevated serum IgE, and the age (50-59 years) at the initiation of depression in the PPD-induced delayed skin reaction was younger than that (over 70 years) in the C. albicans-induced reaction.</p>

Abstract Delayed cutaneous hypersensitivity towards Candida albicans was examined in 200 patients with bronchial asthma in relation to patient age and the level of total IgE. 1. Delayed skin reactivity towards C.albicans was depressed in the patients between the ages of 10 and 20 and in those over the age of 61. A significant difference was present in delayed skin reactivity between the groups of 10-20 and 41-50 years old. 2. The frequency of the patients with positive delayed skin reactivity towards C.albicans was the highest in those with low levels of total IgE (0 -100 IU/ml) and the low est in those with high levels of total IgE (over than 1001 IU/ml). The results suggest that cell-mediated immunity towards C.albicans is depressed re lating to atopics in the patients between 10 and 20 and to aging in the patients over 61.
Abstract Alternative 気管支喘息200例を対象にカンジダに対する即時型および遅延型皮膚反応を観察し,これらの皮膚反応と年令,血清IgE値との関連について検討を加えた。1. カンジダに対する遅延型皮膚反応は,10~20才の年齢層および61才以上の年齢層の症例において,その陽性率の低下が観察された。そして,10~20才の年齢層と41~50才の年齢層の症例では,両者間で陽性率の有意の差が見られた(p<0.001)。2. カンジダに対する遅延型皮膚反応の陽性率は,血清IgE値が低い(0~100 IU/ml)症例において最も高く,一方血清IgE値が高い(1001IU/ml以上)症例において最も低いという傾向が見られた。これらの結果は,カンジダに対する細胞性免疫は,10~20才の年齢層ではアトピーと,また61才以上の年齢層では加齢と関連して抑制されることを示唆するものと考えられる。

Abstract Serum levels of Candida-specific IgG(4) antibodies were examined in 66 patients with bronchial asthma, relating to patient age and asthma severity. 1. The levels of Candida-specific IgG(4) antibodies were the highest in patients with 60+years of age, compared to the levels in cases with 0-39 and 40-59 years of age. 2. In cases with 40-59 years of age, the levels of Candida-specific IgG(4) were significantly higher in cases with long-term steroid therapy (severe intractable asthma) than in cases without steroid regimen. The results suggest that increased levels of Candida-specific IgG(4) were observed in relation to patient age and asthma severity.

Abstract Bronchial hyperresponsiveness was examined in relation to age, ventilatory function, and the proportion of bronchoalveolar lavage (BAL) cells in 39 patients with type Ia asthma (simple bronchoconstriction) (25 with type Ia-1 and 14 with type Ia-2), classified by clinical symptoms. 1. The proportion of BAL eosinophils was significantly higher in type Ia-2 than that in type Ia-1 asthma patients. 2. Bronchial reactivity to methacholine was not different between type Ia-1 and type Ia-2 asthma patients. 3. Bronchial hyperreactivity tended to decrease as patient age was higher in both types of asthma. Neither ventilatory function (FEV1.0%) nor the proportions of BAL lymphocytes and neutrophils was not correlated with bronchial hyperresponsiveness in both types of asthma. 4. Bronchial reactivity to methacholine more dereased with the increase in the proportion of BAL eosinophils in both type Ia-1 and Ia-2 asthma patients. The results show that bronchial hyperresponsiveness in patients with type Ia asthma is correlated to patients age and the proportion of BAL eosinophils.
Abstract Alternative 気管支喘息患者Ia型(単純気管支れん縮型)39人(Ia-1型25人,Ia-2型14人)の気道過敏性を年齢,呼吸機能検査,気管支肺胞洗浄液(BAL)中の細胞成分と関連で検討を行った。1.BAL液中の好酸球の比率はIa-1型に比べIa-2型で優位に高値であった。2.メサコリンに対しての過敏性はIa-1型とIa-2型とで差を認めなかった。3.気道過敏性はどちらの病型においても年齢にともなって減弱する傾向にあったが,一秒率及びBAL液中の好中球,リンパ球の比率とは相関しなかった。4.メサコリンに対しての気道過敏性はIa-1型,Ia-2型ともにBAL液中の好酸球の比率が増加するにしたがって亢進した。以上より単純気管支れん縮型(Ia型)の気管支喘息患者の気道過敏性はその年齢,BAL液中の好酸球の比率に相関することが示唆された。

Abstract Ventilatory function was examined in 20 elderly patients with bronchial asthma in relation to clinical asthma types, and the results were compared with those of younger asthmatics. 1. Ventilatory parameters such as FEV(1.0%), % PEFR, % MMF, % V(50) and % V(25), which repressent obstructive ventilatory dysfunction, were in general lower in older asthmatics than in the youger cases. 2. The values of % V(50) and % V(25), representing ventilatory dysfunction in small airways, were significantly lower in the older subjects with type Ib and II compared to the younger cases with same types. 3. Markedly decreased values in ventilatory parameters, particularly in % MMF, % V(50) and % V(25) were observed in both older and younger subjects with type II. The results suggest that ventilatory function decreases with aging and the decrease is related to the pathophysiological changes in the airways.
Abstract Alternative 60才以上の老年気管支喘息20例(平均年令;66.7才)を対象に,その換気機能について,臨床病態別に59才以下の症例(平均年令;44.9才)との比較検討を行った。1.FFV(1.0%), % PEFR, % MMF, % V50, % V25などの閉塞性換気障害を表すパラメーターは,59才以下の症例に比べ老年症例で全般的に低い傾向が見られた。2.小ないし細気管支領域の換気榛能を反映すると考えられる% V(50)および% V(25)は,Ib型およびII型喘息を示す老年症例において,59才以下の症例に比べ,有意に低い値を示した。3.II型喘息症例では,59才以下および老年症例のいずれにおいても, % MMF, % V(50)および% V(25)は他の臨床病型にくらべ著明に低い値を示した。これらの結果は,気管支喘息における換気機能は,加令とともに低下傾向を示すこと,そしてその低下は臨床病態と関連していることを示しているものと考えられた。

Abstract Clinical features of bronchial asthma in the elderly were analyzed by observlng IgE-mediated allerglc reactions evaluated by immediate skin reaction and specific IgE antibodies to allergens, ventilatory function and cellular composition in bronchoalveolar lavage (BAL) fluid. 1. The frequency of positive immediate skin reaction and positive RAST score to allergens was in general low in the elderly patients over age 70. 2. Ventilatory function was widely variegated, and fifteen cases (60%) of the 25 Subjects showed considerably high values of FEV(l.0%), % PEFR, % MMF, % V(50) and % V(25), and the mean value of FEV(1.0%) in these cases was 71.3%. 3. The decreased value of % V(25) was related to BAL neutrophilia in 2 cases, but any correlation was not found between BAL neutrophilia and decreased value of % V(25) in 9 csese of the eleven subjects who had the BAL examination. The results show that in asthma of elderly patients, IgE-mediated allergic reactions are weak, and that a decreased value of % V(25) can be observed without BAL neutrophilia.
Abstract Alternative 70才以上の老年者気管支喘息の特徴について,アレルゲンに対する即時型皮膚反応および特異的IgE抗体,換気機能,気管支肺胞洗浄液(BAL)中の細胞成分などにより検討した。1.アレルゲンに対する即時型皮膚反応および特異的IgE抗体の陽性率は,全般的にかなり低い傾向を示した。2.換気機能にはかなりのばらつきが見られたが,25例中15例(60%)では,,いずれの換気パラメー ターもかなり高い値を示し,これらの症例の平均FEV(1.0%)は71.3%であった。3.BALを施行した11例中,% V(25)値の低下とBAL中好中球増多との間に関連の見られた症例は2例のみで,他の9例では% Ⅴ(25)値の高度な低下にもかかわらず,BAL中の好中球増多は見られなかった。これらの結果より,老年者気管支喘息では,IgEにmediateされるアレルギー反応は全般的に弱いこと,またBAL液中好中球増多なしに% V(25)値の高度な低下が出現してくることが示された。

Abstract The release mechanism of chemical mediators from basophils and mast cells was discussed when these cells were stimulated by different antigens and anti-IgE. 1. Ca(2+) influx into mast cells increased after stimulation by antigen. The increased Ca(2+) uptake by mast cells was inhibited by antiallergic agents, disodium cromoglycate (DSCG) and tranilast, and calcium antagonists, nifedipine and nicardipine. 2. The dose-response curve of histamine release by antigen was different from that by anti-IgE. The maximum release of histamine by house dust was, however, similar to that by anti-IgE. House dust- and anti-IgE-induced release of histamine increased with higher- serum IgE levels. On the contrary, the release of histamine by Candida albicans was not releated to serum IgE levels, and the release by C. albicans did not parallel therelease by anti-IgE.
Abstract Alternative ハウスダスト,カンジダなどの抗原および抗ヒトIgE刺激時の,抗塩基球および肥満細胞からの化学伝達物質遊離機序について,若干の検討を行った。1.肥満細胞へのCa(2+)の流入は,抗原刺激後に増加する傾向を示した。この肥満細胞のCa(2+)取り込みの増加は,抗アレルギー剤であるクロモリン(DSCG)やトラニラストやCa(2+)拮抗剤であるニフェジピンやニカルジピンによって抑制された。2.抗原(ハウスダスト)によるヒスタミン遊離の濃度依存性カーブは,抗ヒトIgEによるカーブとは異なっていた。しかし,ハウスダストが抗原である症例では,抗原による最高ヒスタミン遊離値は,抗ヒトIgEによる遊離値とある程度の相関を示した。そして,抗原(ハウスダスト)および抗ヒトIgEによる好塩基球からのヒスタミン遊離は,血清IgE値が上昇するにつれて,増加する傾向が見られた。一方,カンジダによるヒスタミン遊離は,血清IgE値との相関は無く,また,抗ヒトIgEによるヒスタミン遊離との間にも関連は見られなかった。

Abstract <p>Bronchial asthma was classified by the pathophysiology and by the mechanism of onset of the disease. Forty asthmatics who had serum IgE levels lower than 200 IU/ml were evaluated by two classification methods. 1. In asthma classified by a score based on clinical findings and examinations, the characteristics of the findings and examination results were compared among three asthma types, i.e., Ia. simple broncho-constriction type, Ib. bronchoconstriction+hypersecretion type, and II. bronchiolar obstruction type. Type Ib patients, in addition to manifesting hypersecretion, had a significantly higher proportion of eosinophils in the bronchoalveolar lavage (BAL) fluid compared to other asthma types. Significantly decreased values for ventilatory parameters and an increased proportion of BAL neutrophils were found in type II compared with other asthma types. 2. In a new classification by mechanism of onset, asthma was classified into three types according to the degree of participation of IgE-mediated reactions associated with specific IgE antibodies and serum levels of total IgE: asthma induced by definite IgE-mediated reaction (atopic asthma), possible IgE-mediated reactions (asthma), and asthma induced by non-IgE-mediated reaction (asthma syndrome).</p>

Abstract Twenty-one patients with atopic asthma were classified into three types according to their symptoms (clinical diagnosis): Ia, simple bronchoconstriction; Ib, bronchoconstriction + hypersecretion; and II, bronchiolar obstruction, and this classification was compared with a classification made according to clinical findings and examinations (score diagnosis). Type Ib asthma was characterized by the increased incidence of eosinophils in bronchoalveolar lavage fluid (BALF), while type II was characterized by ventilatory dysfunction in small airways and the increased incidence of neutrophils in BALF. Four patients, whose expectoration was between 50 and 99ml/day, of the 12 with type Ia assessed by clinical diagnosis were evaluated as type Ib by score diagnosis. One patient with type II by clinical diagnosis was assessed as questionable type II by score diagnosis. In the other 16 patients, the clinical and score diagnoses were the same.

Abstract The generation of leukotrienes B4 (LTB4) and C4 (LTC4) by peripheral leukocytes stimulated with Ca ionophore A23187 was examined in 17 patients with pulmonary emphysema. They were divided into three groups according to the mean CT number; A (<-940 HU), B (-940 ≦, <-930 HU), and C (-930 HU ≦ ).1. The values of FVC (% predicted), FEV1.0% and DLco (% predicted) showed a tendency to decrease as the mean CT number was smaller. The value of % FVC was significantly lower in patients with group A than in those with group C (p<0.05). 2. The generation of both LTB4 and LTC4 was significantly higher in patients with emphysema compared to the generation in healthy subjects (LTB4;p<0.05, LTC4;P<0.05). 3. The generation of LTB4 and LTC4 in patients with emphysema was higher as the mean CT number was larger (severity of the disease become less). The LTC4 production was significantly higher in patients with group C(mild or moderate type of emphysema) than in those with group A(advanced type of emphysema). These results suggest that the generation of LTB4 and LTC4 is higher in patients with mild or moderate type of emphysema than in those with advanced type of the disease.

Abstract The proportion and number of lymphocytes in the airways were analyzed in 15 patients with a high proportion of lymphocytes in bronchoalveolar lavage (BAL) fluid (more than 30%) and in 17 patients with less than 20% of BAL lymphocytes. 1. Both atopic and nonatopic asthma patients with a high proportion of BAL lymphocytes were aged more than 50 years. In contrast, the age of patients with less than 20% of BAL lymphocytes ranged widely, from 29 to 63 years, in the two asthma types. 2. Age at onset of the disease, serum IgE levels, and ventilatory function test were not related to the proportion of BAL lymphocytes. 3. In patients with a high proportion of BAL lymphocytes, the mean proportion of these cells was 47.3% in atopic patients and 36.4% in non-atopic patients, i. e., there was no significant difference between the two asthma types. The absolute number of BAL lymphocytes in these patients was significantly higher in atopic (5.62×10(6)) than in nonatopic asthma (0.77×10(6)) (p<0.01). These findings show that an increased number of lymphocytes in the airways is clearly related to patient age and IgE-mediated allergic reaction.
Abstract Alternative 気管支肺胞洗浄(BAL)液中のリンパ球頻度が30%以上の15例および20%以下の17例の気管支喘息患者を対象に,BAL液中リンパ球頻度と年齢およびIgE系反応との関連について検討を加えた。1.BALリンパ球が高頻度(30%以上)を示す症例は,アトピー型,非アトピー型を問わず,50才以上の年齢層に多い傾向が見られた。一方,BALリンパ球20%以下の症例の年齢は,29-63才まで幅広く分布していた。2.発症年齢,血清IgE値,換気機能とBAL液中リンパ球頻度との間には関連は見られなかった。3.BAL液中リンパ球頻度が高い症例では,アトピー型では平均リンパ球頻度は47.3%,非アトピー型では36.4%であったが,両群間には有意の差は見られなかった。しかし,BAL液中のリンパ球の絶対数は,アトピー型(5.62×10(6))において,非アトピー型(0.77×10(6)) に比べ有意に高い値を示した(p<0.01)。これらの結果は,気道内リンパ球の増加は,患者年齢とIgE系反応と密接に関連していることを示唆している。

Abstract Cellular composition of bronchoalveolar lavage (BAL) fluid was examined in 11 elderly asthmatics over the age of 70, and the results were compared with those of 11 younger asthmatics under the age of 50. In the subjects with mild asthma, the proportion of BAL cells in the elderly subjects was 86.2% macrophages, 11.0% lymphocytes, 1.9% neutrophils, 0.9% eosinophils and 0.08% basophilic cells. The proportion of neutrophils and eosinophils in the BAL fluid was slightly higher in younger subjects with mild asthma compared with that in elderly subjects, although no significant difference was found between the two groups. In subjects with severe asthma, the proportions of lymphocytes, neutrophils, eosinophils and basophilic cells were more increased in both younger and older patients compared to those with mild asthma, and a significant increase in the number of BAL eosinophils was found in younger subjects with severe asthma compared to those with mild asthma (p < 0.05). However, no significant difference was present in the proportion of BAL cells between younger and older patients with severe asthma. The results reveal that BAL cells are more increased in subjects with suvere asthma than in those with mild asthma in both younger and older subjects, and show the possibility that this increase is more predominant in neutrophils in older subjects and in eosinophils in younger subjects.
Abstract Alternative 70才以上の老年者気管支喘息11例(平均年齢71.4才)を対象に,重症度と気道細胞反応との関連について検討を加えた。なお,対照として50才以下の喘息症例11例(平均年齢33.5才)を選んだ。1.老年者の軽症型喘息における気管支肺胞洗浄(BAL)液中の出現細胞の頻度は,マクロファージが86.2%,リンパ球が11.0%,好中球が1.9%,好酸球が0.9%,好塩基性細胞が0.08%であった。BAL液中の好中球,好酸球の頻度は若青年症例でやや高い傾向が見られたが,両群間に有意の差は見られなかった。重症例では,老年症例,若青年症例とも,軽症例に比べリンパ球,好中球,好酸球などのBAL細胞の出現頻度が増加しており,特に好酸球では若青年症例の重症例で軽症例に比べ有意に高い頻度が観察された。これらの結果は, リンパ球,好中球,好酸球などのBAL細胞は,軽症例に比べ重症例で増加してくること,そして,その増加は老年症例では好中球,若青年症例では好酸球の増加が特徴的であることを示唆しているものと考えられた。

Abstract Age-related changes in IgE-mediated allergic reaction were examined in patients with late onset asthma, whose asthma occured over the age at onset of 40. 1. The number of patients with a high serum IgE level over 3001U/mℓ was larger in those between the ages at onset of 40 and 49 and over age at onset 60 than in those between the ages at onset 50 and 59. 2. A positive RAST score to Hdm and cockroach allergens was more frequently found in patients between 40 and 49 and over age 60 at onset compared to those between 50 and 59 at onset. In contrast, the number of patients with a positive RAST to Candida was larger in those between 50 and 59 at onset than in those of between 40 and 49 and over 60 at onset. 3. Severe asthma was more frequently and slight asthma was less frequently observed in patients between 50 and 59 at onset than in those of the other age at onset groups. These results suggest that IgE-mediated allergic reaction in patients between the ages at onset of 50 and 59 is different from that in those with early onset asthma, and that the reaction in patients between the ages at onset 40 and 49 and over 60 resembles to the reaction in those with early onset asthma.
Abstract Alternative 発症年令が40才以上の中高年発症型喘息患者におけるIgE系アレルギー反応の加令による変化について検討を加えた。1.発症年令が40から49才と60才以上の患者では,50から59才の患者に比して血清IgE値が300IU/mℓ以上の高値を示す頻度が高い傾向が見られた。2.ダニ,ゴキブリに対するRAST陽性率は発症年令が50から59才の患者に比して,40から49才と60才以上の患者で高値を示した。一方,カンジダに対するRAST陽性率は,発症年令が40から49才と60才以上の患者に比して,50から59才の患者で高値を示した。3.発症年令が50から59才の患者では,他の発症年令の患者に比べて,重症例が多く,軽症例が少ない傾向が見られた。以上の結果から,発症年令が50から59才の患者のIgE系アレルギー反応は若年発症型喘息患者と異なり,発症年令が40から49才と60才以上の患者のIgE系アレルギー反応は若年発症型喘息患者と 類似することが示唆された。

Abstract The number of CD4(+) T-Iymphocytes, CD4/CD8 ratio, and the number of IL2R(+) T-Iymphocytes (CD25) were examined in 14 patients with bronchial asthma, and the results were compared in three different asthma stages : symptom-free stage, wheeze stage, and attack stage. 1. The proportion of blood CD4(+) T-lymphocytes was more decreased in patients with asthma attacks than in those without symptoms. The CD4/CD8 ratio was also more decreased in patients with attacks than in those without symptoms. However, these differences were not significant. 2. The proportion of blood activated T cells (IL2R(+) cells, CD25) was significantly increased in patients with attacks than in those without symptoms. The proportion of activated T cells in 5 asthma patients was 2.9±0.8% in symptom-free stage and 6.6±1.1% in attack stage(p<0.001). These findings show that numbers of activated T-lymphocytes in peripheral blood were increased during asthma attacks, and this increase suggests the participation of activated T cells in the pathogenesis of asthma.
Abstract Alternative 気管支喘息14例を対象に,末梢血CD4(+)リンパ球の頻度,CD4/CD8比およびIL2R(+)Tリンパ球の頻度について,喘息発作との関連のもとに検討を加えた。1.CD4(+)リンパ球の頻度は,非発作時の症例で最も高く,喘鳴のみの症例,発作の見られる症例へと順次低くなる傾向が見られたが,推計学的には有意の差は見られなかった。CD4/CD8比も同様に,非発作時に最も高く,発作を有する症例では非発作時に比べ低い値を示したが,推計学的には有意の差は見られなかった。2.IL2R(+)Tリンパ球(activated Tリンパ球)の頻度は,非発作時の症例で最も低く(3.5±1.1%),喘鳴のみをともなう症例(3.8±1.1%),発作の見られる症例(5.8±1.9%)へと順次高くなる傾向を示し,発作のある症例では,非発作および喘鳴のみの症例に比べ有意に高い値 を示した。また,非発作時と発作のある時期にIL2R(+)Tリンパ球を観察し得た5症例では,非発作時2.9±0.8%,発作のある時期6.6±1.1%であり,発作のある時期に有意の高値を示した(p<0.001)。これらの結果は,発作のある時期にはactivated Tリンパ球の頻度が増加すること,そして,この増加はactivated Tリンパ球が喘息発作の病態と密接な関連を有していることを示唆するものと考えられた。

Abstract Effects of complex spa therapy, which comprises swimming training in a hot spring pool, inhalation of iodine salt solution and fango therapy, were analyzed in patients with steroid-dependent intractable asthma (SDIA) by comparison between the subjects with and without efficacy of the therapy. 1. The complex spa therapy was effective in the patients with lower levels of FEV(1.0%) and % PEFR. 2. The complex spa therapy was not always effective in the patients with a low value of % V(25), which represents depressed airflow in the small airways. 3. The efficacy of the complex spa therapy was found in the patients showing a low value of % V(25) accompanied by BAL neutrophilia, but not found in those without increased proportion (more than 10% ) of neutrophils in BAL fluid. The results reveal that the complex spa therapy is effective in patients with SDIA showing low values of FEV(1.0%) and % PEFR, and in those with a low value of % V(25) and BAL neutrophilia.
Abstract Alternative ステロイド依存性重症難治性喘息を対象に,温泉プール水泳訓練,ヨードゾル吸入療法.鉱泥湿布療法からなる複合温泉療法の臨床効果の解析を行った。1.複合温泉療法は,FEV(1.0%)および% PEFR値の低い症例により有効であった。2.複合温泉療法は、細気管支領域の換気障害を示すと考えられる% V(25)値が低い症例に対して,必ずしも有効ではなかった。3.複合温泉療法の効果は,BAL液中好中球増多(10%以上)が見られ、かつ% V(25)値が低い症例により有効であったが、同様に% V(25)値が低くても,BAL液中に好中球増多 が見られない症例に対しては,有効ではなかった。以上の結果より,複合温泉療法はFEV(1.0%)や% PEFR値の低く,またBAL液中好中球増多が見られ,かつ% V(25)値が低いようなステロイド依存性重症難治性喘息に対して有効性が高いことが示唆された。

Abstract Action mechanisms of complex spa therapy (swimming training in a hot spring pool, inhalation with iodine salt solution, and fango therapy) were studied in relation to patient age, clinical asthma type, and airway inflammation. Actions of spa therapy were observed by two clinical effects : direct and indirect effects. Improvement of subjective symptoms, ventilatory function, and bronchial hyperresponsiveness was observed as direct effects of spa therapy, and improvement of suppressed function of adrenocortical glands as indirect effects of the therapy. The clinical effects of spa therapy were higher in patients over the age of 40. Regarding clinical asthma type, the effects were larger in patients with type Ib and type II asthma than in those with type Ia. The efficacy of spa therapy was closely related with airway inflammation in patients with type Ib and type II asthma.
Abstract Alternative 複合温泉療法(温泉プール水泳訓練,ヨードゾル吸入,鉱泥湿布療法)の作用機序が,年齢,臨床病型,気道炎症反応との関連のもとに検討された。温泉療法の作用機序は,2種類の臨床効果,すなわち,直接効果と間接効果により観察された。自,他覚症状の改善,換気機能の改善,そして,気道過敏性の改善などが,温泉療法の直接効果として,また,副腎皮質機能の改善が間接効果とし て観察された。温泉療法の臨床効果は,40才以上の症例においてより有効であり,また,臨床病型別では、Ia型に比べ,Ib型およびⅡ型においてより有効であった。Ib型やⅡ型の気管支喘息では,温泉療法の作用機序と気道炎症反応との間に密接な関連が認められた。
