Abstract The degree and characteristic of airway inflammation were evaluated by the proportions of bronchoalveolar lavage (BAL) cells. Clinical asthma types such as Ia. simple bronchoconstriction, Ib. bronchoconstriction + hypersecretion, and Ⅱ. bronchiolar obstruction correlate with airway inflammation. The increased proportion BAL neutrophils is characteristic of type Ⅱ asthma, and increase in BAL eosinophil count is often observed in type Ib asthma. Bronchial hyperresponsiveness also correlates with airway inflammation. Action of spa therapy has been speculated to be related to airway inflammation, since the therapy has no action inhibiting IgE-mediated allergic reaction. In fact, spa therapy is more effective in patients with type Ib and type Ⅱ than in those with type Ia showing slight degree of airway inflammation. Bronchial hyperresponsiveness is also improved by spa therapy. From a point of view, the direct action of spa therapy may be to clean airways and improve damaged mucous membrane of the airways, leading to suppression of airway inflammation.
Abstract Alternative 気道炎症反応の程度や特徴が,気管支肺胞洗浄液(BAL)中の細胞成分によって評価された。Ia.単純性気管支攣縮型,Ib.気管支攣縮+過分泌型,Ⅱ.細気管支閉塞型などの各臨床病型は気道炎症反応と関連している。BAL液中好中球増多は,Ⅱ型喘息の特徴的所見であり,また好酸球増多はIb型喘息でしばしば観察される。気道過敏性もまた気道炎症反応と関連している。温泉療法の作用機序としては,温泉療法にIgEにmediateされるアレルギー反応(液性因子相)を抑制する作用がないことから,気道炎症反応(細胞性因子相)の抑制が推測されている。実際,温泉療法は,気道炎症反応が軽度なIa型喘息に比べ,Ib型やⅡ型などの明らかに気道炎症反応をともなう病型に対してより有効である。気道過敏性もまた温泉療法により改善される。これらの 結果から,温泉療法は,気道を清浄化し,気道粘膜を正常化することによって,気道炎症反応を抑制していくものと考えられる。

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。

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 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 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 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 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 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 Characteristics of airway response in steroid-dependent intractable asthma (SDIA) were examined in 86 asthma patients (43 with SDIA and 43 with non-SDIA) divided into three age groups: 20-39, 40-59 and 60+ years, by observing cellular composition of bronchoalveolar lavage (BAL) fluid and ventilatory function. 1. The level of serum cortisol was significantly lower in patients with SDIA than in those with non-SDIA in all age groups. 2. The proportion of lymphocytes in BAL fluid was significantly decreased in patients with SDIA compared to results in non-SDIA patients in the age between 40-59, and over 60+ years, While BAL neutrophils were significantly increased in SDIA patients compared to results in non-SDIA patients in the age group over 60 years. 3. Of ventilatory parameters, the values of % FVC, FEV(1.0%), % MMF and % V(25) were significantly lower in SDIA patients over the age of 60 compared with non-SDIA subjects of the same age group. These results show that in SDIA patients the proportion of BAL lymphocytes decreases and the proportion of BAL neutrophils increases with aging, and that ventilatory function in SDIA patients also decreases with aging compared to non-SDIA patients.
Abstract Alternative 年齢により3群(20-39才,40-59才,60才以上)に分類された気管支喘息86例(ステロイド依存性重症難治性喘息:SDIA;43例,非SDIA;43例)を対象に,気管支肺胞洗浄液(BALF)中の細胞成分および換気機能よりSDIAにおける気 道反応の特徴を検討した。1.血清コーチゾ-ル値は,SDIA症例において, 非SDIA症例に比べいずれの年齢層においても有意の低値を示した。2.BALF中リンパ球頻度は,40-59才および60才以上のSDIA症例において,同年齢の非SDIA症例に比べ有意の低値を示した。一方,BALF中好中球頻度は,60才以上のSDIA症例で,同年齢層の非SDIA症例に比べ有意に高い値を示 した。また,BALF中好酸球頻度は,いずれの年齢層においても,SDIAと非SDIA症例の間に有意の差は見られなかった。3.換気機能では,% FVC, FEV1.0%,% MMF, % V(25)などの換気パラメーターは,60才以上の SDIA症例において,同年齢層の非SDIA症例に比べて有意の低値を示した。 これらの結果は,40-59才あるいは60才以上のSDIA症例では,非SDIA症例に比べ,BALF中リンパ球頻度の低下,好中球頻度の増加,換気パラメーター値の低下などがより高度に見られることを示している。

Abstract Ventilatory function was examined in 55 patients with asthma (25 older patients over the age of 60 and 30 younger patients under the age of 59) in relation to four clinical types classified by clinical symptoms and signs. 1. Regarding cellular composition of bronchoalveolar lavage (BAL) fluid, number of BAL neutrophils was significantly increased in type II, bronchiolar obstruction type, of older and younger patients compared to that in type la-1 and type la-2 of same patients. In contrast, BAL eosinophilia was observed in type la-2 of both older and younger patients and in type Ib of younger patients. 2. The values of % FVC, FEV(1.0%) and % PEFR were not significantly different among four clinical types of asthma and between older and younger patients, although the values of these ventilatory parameters in type II asthma showed a tendency to be lower compared to other clinical types. 3. The values of % MMF, % V(50), and % V(25), showing ventilatory dysfunction of small airways, were lowest in type II asthma of both older and younger patients among four clinical types. A significant difference in these ventilatory parameters of type II asthma compared to type la-1 asthma was observed in younger patients, but not in older patients. These results show that ventilatory dysfunction of small airways is related to clinical asthma types in younger patients, and to aging rather than asthma types in older patients.

Abstract Free radicals have been suspected to play an important role in the pathogenicity of chronic pancreatitis. We reviewed studies on free radicals in chronic pancreatitis in both c1inical and experimental aspects. Many clinical studies have provided circumstantial evidence for the close relation between free radicals and chronic pancreatitis. However, few experimental studies in animals on relation between free radicals and chronic pancreatitis have been reported, because adequate experimental models for elucidating a pathological role of free radicals in chronic pancreatitis have not been established. The research concerning the role of free radicals in chronic pancreatitis is expected to improve our understanding the pathological mechanisms of the disease.
Abstract Alternative 慢性肺炎の発症機序は不明な点が多いが、フリーラジカルがそれに関与することが示唆する報告も多い。しかし,その直接的な証明はなされていない。慢性膵炎の病態にフリーラジカルがどのように関与するかを理解することは慢性膵炎の発症機序の解明の一助になると考え,臨床的および実験的側面から慢性膵炎とフリーラジカルの関係を概説した。

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 Alternative % 肺活量が75%以下の低値を示す気管支喘息について,その臨床的特徴を,臨床病型や重症度との関連のもとに検討した。1.% 肺活量と年齢との間には関連は見られなかった。2.% 肺活量と臨床病型との問には有意の関連が見られ,Ⅱ型喘息(細気管支閉塞型)における% 肺活量は,Ia-1型やIa-2型などの単純性気管支攣縮型に比べ,有意に低い値を示した。3.% 肺活量はまた喘息の重症度と有意の関連を示した。これらの症例では,喘息の重症度が増すにつれて,% 肺活量は減少する傾向が見られた。4.これら症例の低値を示す% 肺活量は,治療(複合温泉療法)により改善される傾向が見られた。以上の結果より,これらの症例(% 肺活量が75%以下)では,% 肺活量と喘息の重症度との間にある程度の関連があることが明らかになった。

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 Alternative 気管支喘息28例および慢性閉塞性細気管支炎9例を対象に,気道炎症反応の臨床的意義について検討を加えた。1.気管支肺胞洗浄(BAL)液中の総細胞数は,慢性閉塞性細気管支炎において著明に増加しており(51.0×10(6)),気管支喘息(9.6×10(6))との間に有意の差が見られた。2.BAL液中マクロファージの頻度は気管支喘息において,慢性閉塞性細気管支炎に比べ有意に高い値を示したが,絶対数での比較では両疾患群間に有意の差は見られなかった。 3.BAL液中リンパ球の頻度は,気管支喘息においてやや高い傾向が見られたが,絶対数の比較では慢性閉塞性細気管支炎において有意に高い値であった。 4.BAL液中の好中球は,その頻度および絶対数とも慢性閉塞性細気管支炎において著明に増加しており,これは気管支喘息と比べ有意に高い値であった。 5.BAL液中好酸球の頻度および絶対数は,気管支喘息においてやや高い値であったが,両疾患群間に有意の差は見られなかった。以上の結果より,気管支喘息における気道炎症反応は,慢性閉塞性細気管支炎ほど高度ではない ことが明らかにされた。

Title Alternative 気管支喘息における複合温泉療法と気道炎症反応

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 Alternative 気管支喘息55例を対象に,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)を試み,その臨床効果と気道炎症反応との関連について,若干の検討を加えた。1.複合温泉療法の臨床効果では,著効15例(27.3%),有効32例(58.2%),やや有効6例,無効2例であり,明らかに有効と判断された症 例は,55例中47例(85.5%)であった。2.複合温泉療法は,気管支肺胞洗浄液(BALF)中の細胞成分(リンパ球,好中球,好酸球など)が多い症例,すなわち気道炎症反応がより強い症例により有効であった。このことは,複合温泉療法が,単純性の(化学伝達物質による)気管支攣縮よりも,気道炎症反応をともなった病態により強く影響を及ぼすことを示している。3.複合温泉療法による換気機能の改善(1秒量)は,BAL液中の好中球数が少ない症例においてより高度であった。このことは,BAL液中に高度な好中球増多が見られる症例に対しては,より長期的な複合温泉療法が必要であることを示しているものと考えられた。

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 Alternative 努力肺活量(% FVC)低値を示す気管支喘息の臨床病態を明らかにするために気道炎症ならびに臨床病型との関連について検討を行った。% FVCが80%未満の気管支喘息患者32名を対象として,スパイロメトリー,気管支肺胞洗浄(BAL)を施行し,臨床病態を解析し,治療効果の評価を行なった。1.対象中24名(75%)の患者がステロイド依存性重症難治性喘息であった。2.細気管支閉塞型喘息患者において,% FVC値の有意の低下が認められ,BAL液中のリンパ球の減少と好中球の増加が認められた。3.FVC値,FEV1.0億の治療による改善は,BAL液中好酸球の増加を示す過分泌型喘息においては認められが,BAL液中好中球の増加を示す細気管支閉塞型喘息においては認められなかった。 以上より喘息患者における% FVC値の低下は気道炎症と関連しており,細気管支閉塞型喘息における治療による可逆性は著しく低下していることが示唆された。

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 Alternative ダニ喘息14例を対象に,ハウスダストエキスによる気道遊走細胞からのヒスタミン遊離と加齢との関連について検討を加えた。1.気管支肺胞洗浄液(BALF)中の総細胞数は,20-39才の症例群(6.25×10(6)) に比べ,40才以 上の症例群(9.1×10(6)) でやや多い傾向が見られたが,推計学的には有意差は見られなかった。2.BALF中好酸球数は,20-39才と40才以上の症例群間に差は見られなかった。3.BALF中好塩基性細胞数は,40才以上の症例群(0.39±0.24×10(2)/mℓ)に比べ,20-39才の症例群(1.85±1.03×10(2)/mℓ)において有意に多い傾向が見られた(P<0.001)。4.ハウスダストエキスによるBALF中細胞からのヒスタミン遊離は,40才以上の症例群(0%) に比べ20-39才の症例群(38.1±24.8%)において有意に高い結果が得られた(P<0.001)。これらの結果より,ダニ喘息(アトピー型喘息)における気道遊走細胞からのヒスタミン遊離は,加齢とともに減少することが示唆された。

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.
Abstract Alternative アトピー型気管支喘息末梢血好塩基球を用い,抗原および Ca ionophore A23187 刺激時のヒスタミン遊離およびその形態的変化について比較検討した。1.抗原刺激時には, Ca ionophore A23187 刺激時に比べ,好塩基球からのヒスタミン遊離および好塩基球数の減少の程度は,より急激でかつ高度であった。2.好塩基球の形態的変化,すなわち,長経/短経比の増大,限局性顆粒あるいは偽足を有する好塩基球の出現頻度の増加などの運動能の亢進を示唆する好塩基球の形態的変化は, Ca ionophore A23187 に比べ抗原刺激時により高度であった。一方,平均直径の増大,5個以上の空砲を有する好塩基球の出現頻度の増加などの,むしろ膨化傾向を示唆する好塩基球の形態的変化は,抗原刺激時に比べ, Co ionophore A23187 刺激時により高度であった。これらの結果より,抗原刺激によるIgE受容体のbridgingが,好塩基球を活性化し,運動能の亢進をひき起こすものと判断された。

Abstract ERCP直後にCTを撮影するERCP後CTはERCPの際に膵内に注入された造影剤をCTで検出するため,ERCPでは得られない情報が得られる利点がある。われわれはERCP後CTが診断や治療方針の決定に有用であった膵嚢胞の4例を経験した。膵嚢胞では主膵管との連絡,嚢胞の部位,性状診断にERCP後CTは有用な検査法であり,文献的考察を含めて報告した。
Abstract Alternative Post-ERCP CT (computed tomography (CT) examination performed immediately after endoscopic retrograde cholangiopancreatography) detects the contrast medium injected into the pancreatic duct and cystic lesions at the time of ERCP and, therefore, has the advantage of obtaining information which cannot be obtained by ERCP alone. We have experienced four cases of pancreatic cysts in which post-ERCP CT was useful for diagnosis and in deciding on treatment plans. The post-ERCP CT was proved to be a useful method for examining the site and characteristics of the cysts which communicated with the main pancreatic duct.

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 Alternative 局所寒冷負荷の全身の末梢循環に及ぼす影響について検討する目的で,下肢の20℃冷水負荷時における上肢末梢循環の変化をレーザードプラー血流計を用いて数量的に測定し検討を行なった。症例は,下肢に冷え症,しびれ感を有した25歳から86歳までの24症例(平均年齢64.3歳)であった。下肢,上肢の末梢循環を20℃冷水負荷時に,末梢血流量,血液量,血流速度について観察した。上肢の末梢血流量は20℃室内安静時平均5.00mβ/min/100g tissue,血液量は287,血流速度は0.516であった。下肢は血流量2.23,血液量は149,血流速度は0.574であった。上肢の血流量,血液量ともに下肢より多いことが示された。しかし同一症例における上肢と下肢との間の血流量,血液量,血流速度に相関関係は認めなかった。下肢の20℃ 冷水負荷中の上肢の血流量は平均3.69で有意に低下(26.2%)した。下肢はその間1.51で有意に低下(32.3%)した。上肢の血液量は平均241で有意に低下(16.0%)した。下肢はその間113で有 意に低下(24.2%)した。上肢の血流速度は平均0.501で不変であった。下肢はその間0.642で有意に増加(11.8%)した。冷水負荷直後よりそれぞれ負荷前に復帰する傾向を示した。負荷後20分では上肢の血流量は平均5.74で負荷前値に比べて増加(14.8%)傾向を示した。下肢は1.87で負荷前値に比べて低値(83.9%)に留まる傾向にあった。下肢の冷水負荷は上肢の末梢循環にも影響を及ぼすことが数量的に示された。局所の寒冷負荷による体温の低下を防ぐために反射的に全身の皮膚の末梢循環量を低下させていることが示された。
