Abstract The proportions of cells in bronchoalveolar lavage (BAL) fluid, the release of histamine, leukotrienes C(4) and B(4) from leucocytes and BAL cells, and bronchial reactivity to methacholine were examined in 40 patients with asthma in relation to patient age. 1. The proportions of lymphocytes and neutrophils in BAL fluid were higher in older patients over age 60 than in younger patients between 20 and 49. The proportions of eosinophils and basophilic cells in BAL fluid were higher in younger patients than in older patients, and the difference in the proportion of BAL basophilic cells was significant between the two groups (p<0.05). 2. The release of histamine from BAL cells was significantly higher in younger patients than in older patients (p<0.001). The release of LTC(4) from BAL cells was higher in older patients compared to younger patients. 3. Bronchial reactivity to methacholine was higher in younger patients than in older patients. The number of patients reactive to low concentration of methacholine (390μg/mℓ or less) was larger in younger patients (12/16 ; 75.0%) than in older patients (5/14 ; 35.7%). These results suggest that bronchial hyperresponsiveness changes with aging, accompanied by changes in the release of chemical mediators from BAL cells and in the proportion of BAL cells.
Abstract Alternative 気管支喘息を対象に,気管支肺胞洗浄(BAL)液中の細胞の出現頻度,末梢血白血球およびBAL細胞からのヒスタミン,ロイコトリエンC(4),B(4)遊離,気道過敏性などについて,患者年齢との関連のもとに検討を加えた。1.BAL液中のリンパ球および好中球頻度は,60才以上の老齢症例で,20-49才の若青年症例に比べやや高い傾向が見られたが,推計学的には有意の差は見られなかった。BAL液中の好酸球,好塩基細胞の頻度は,若青年症例で,老年症例に比べて高く,特に好塩基性細胞の頻度には両症例群間に有意の差が見られ(P<0.05)。 2.BAL細胞からのヒスタミン遊離は,若青年症例で,老年症例に比べ有意に多い傾向が見られた(P<0.001)。一方,BAL細胞からのロイコトリエンC(4)遊離は,若青年症例に比べ,老年症例で多い傾向が見られたが,両症例群間に有意の差は見られなかった。3.メサコリンに対する気道の反応性は,全般的に若青年症例で,老年症例に比べより強い傾向を示した。そして,390μg/mℓまたはそれ以下の低濃度のメサコリンに反応を示す症例は,若青年症例では16例中12例(75.0%),老年症例では14例中5例(35.7%)であった。以上の結果より,気道過敏性は,BAL細胞からの化学伝達物質遊離の変化やBAL細胞の頻度の変化とともに,加齢の影響を受けることが明らかとなった。

Abstract To clarify the main humoral triggering factor (histamine and/or leukotriene) of the early stage of asthma attacks, the release of histamine and leukotriene C4 (LTC4) from bronchoalveolar lavage (BAL) cells stimulated with Ca ionophore A23187 was examined in 7 patients with atopic asthma, and the results were compared to those in 7 nonatopic asthma patients. 1. The proportion of BAL basophilic cells was significantly higher in atopic patients than in nonatopic patients (p<0.05). 2. The content of histamine in BAL fluid was significantly higher in atopic (2.3mcg/mℓ) comparted to that in nonatopic patients (0mcg/mℓ)(p<0.001). The content of LTC4 was high in nonatopic (2.4ng/mℓ) than in atopic patients (0.5ng/ mℓ), however, this was not significant. 3. The release of histamine from BAL cells was 32.6% in atopic and 0% in nonatopic patients, and this was significant (p<0.001). The release of LTC4 from BAL cells was significantly higher in nonatopic (11.3ng/10(6)cell) than in atopic (3.5ng/10(6)cell)(p<0.02). The results demonstrate that histamine play more important role in atopic patients as a main triggering factor of attacks than LTC4. In contrast, in nonatopic patients, LTC4 is more predominant than histamine during early stage of asthma attacks.
Abstract Alternative 気管支喘息発作初期に関与する液性因子(ヒスタミン,ロイコトリエン)の役割を明らかにするために,気管支肺胞洗浄(BAL)細胞からのカルシウムイオノフォアA23187によるヒスタミンとロイコトリエンC4 (LTC4)遊離の検討を行った。対象はアトピー性喘息患者7名,非アトピー性喘息患者7名とした。1.BAL液中の好塩基性細胞の比率は,アトピー性喘息患者において有意に高値を示した。2.BAL液中ヒスタミン濃度は非アトピー性喘息患者(0mcg/mℓ)に比して,アトピー性喘息患者(2.3mcg/mℓ)において有意に高値を示した。一方,BAL液中LTC4濃度は,アトピー性喘息患者(0.5ng/mℓ)に比し て非アトピー性喘息患者(2.4ng/mℓ)において,高値を示したが,有意差は見られなかった。3.BAL細胞からのヒスタミン遊離は非アトピー性喘息患者(0%)に比して,アトピー性喘息患者(32.6%)において有意に高値を示した。LTC4遊離はアトピー性瑞息患者(3.5ng/10(6)胞)に比して,非アトピー性喘息患者(ll.3ng/10(6)細胞)において有意に高値を示した。以上より,喘息発作初期に関与する液性因子としては,アトピー性喘息患者においてはヒスタミンが重要であり,非アトピー性喘息患者においてはLTC4が,重要であることが,明らかになった。

Abstract 40才~84才(平均64.1才)の患者38例における骨塩量を,ある期間(1~15カ月,平均8.2カ月)をおいて2回,定量的QCT(quantitative computed tomography)法を用いて測定し,その経時的変化によって,骨粗鬆症に対する治療法の効果判定を試みた。その結果,(1)全体として骨塩量に有意の増加は認められなかった。(2)骨強化剤使用例についても骨塩量に有意の増加は認められなかった。(3)運動療法施行者においても骨塩量に有意の増加は認められなかった。以上のことから骨粗鬆症の治療においては,約1年弱の経過では著明な反応は得られにくいものと思われた。ただし,一部の運動療法施行者,骨強化剤使用者において,骨塩量の著明な上昇が認められており,さらに経時的な観察が必要と思われた。

Abstract 当院通院あるいは入院中の女性患者54例を対象に骨塩量を経時的に3回測定し検討を行った。54例の骨塩量の平均は3回とも有意差はなく,年次骨塩変化量は-3.1±14.6mg/cm(3)/yearであった。平均骨塩量の年齢別比較では40才台,50才台,60才台の順に有意な減少がみられ,60才台と70才以上との間には差は認めなかった。また50才台及び70才以上の年代で1年当たりの骨塩量の減少が大きい傾向が窺われた。身長と骨塩量との間に有意の正の相関を認めたが,体重との間には有意の相関を認めなかった。血清中Ca,P及びALPと骨塩量との検討ではいずれも有意の相関を認めなかった。骨塩変化量減少群と増加群との比較では,平均骨塩量及び背景因子の間に差を認めなかった。女性,特にステロイド療法を必要とする患者については閉経の時期にあたる40~50才台より積極的に骨粗髭症対策を考える必要性があると考えられた。また運動療法については温泉プール療法自体を再検討するとともに,骨粗髭症に特異的な運動療法の確立が必要と思われた。
Abstract Alternative Bone mineral densities (BMD) were mesured 3 times in 54 females aged 40 to 84 years old to evaluate about relationship between BMD and osteoporosis therapy or patient background factors. BMD decreased 3.1±14.6mg/cm(3) per year, and BMD values were more decreased in subjects with the age of 50's and over 70's than in those with the age of 40's and 60's. In patients with bronchial asthma or rheumatoid arthritis, treated with corticosteroids (predonisolone : 3-7.5mg/day), BMD were sigfnificantly more decreased than in patients without corticosteroid therapy. There was a significant positive correlation between BMD and body height, but no correlation between BMD and body weight, serum Ca, P, or alkaline phosphatase. No differences in background factors were found between subjects with increased BMD and those with decreased BMD. These results indicate that female patients with corticosteroids need active treatments for the prophylaxis of osteoporosis at the age of 40's or 50's.

Abstract 当院内科に通院または入院中の女性患者24例(57~89才,平均71.8才)を対象とし,定量的QCT法による骨塩量測定と同時に血中骨代謝マーカーを測定し検討を行った。年齢についての検討では,カルシウム(Ca)が70才台で60才台に比べ有意に高値であった以外は年代による有意差は認められなかった。オステオカルシン(OC)とイオン化Ca(Ca(2+))との間にr=-0.50,p<0.01の有意の逆相関を認め,OCとBody mass indexとの間に有意の正の相関(r=0.41,p<0.05)を認めた。平均骨塩量と各生化学parameterとの間には有意な相関はみられなかった。副腎皮質ステロイド剤(ステロイド)投与群では非投与群に比べ,投与群でALP骨型アイソザイム(ALP3)高値,OC低値の傾向がみられた。またステロイド投与症例はすべてOC値が8.4ng/mℓ以下であり,ステロイドによる骨粗鬆症誘発の機序として骨形成の抑制が関与している可能性が考えられた。今後骨塩量と骨代謝マーカーとの関連について,若年者を含めた検討が必要と考えられた。
Abstract Alternative Bone mineral densities (BMD) were measured with QCT (quantitative computed tomography) in 24 females aged 57 to 89 years old to evaluate about relationship between BMD and biochemical parameters on bone metabolism (calcium : Ca, ionized calcium : Ca(2+), alkaline phosphatase : ALP, bone type isozyme of alkaline phosphatase : ALP 3 and osteocalcin : OC) in blood. As for exception that Ca was significantly higher in patients aged of 60's in comparison with those of 70's in the examination with regard to age, no significant differences were observed. Significant opposite correlation (r=-0.50, p<0.01) between OC and Ca(2+) and significant positive correlation (r=0.41, p<0.05) between OC and body bass index were observed. No significant correlation was observed between mean BMD and biochemical parameters. A trend of higher ALP 3 and lower OC was observed in adrenocortical steroid (steroid) administration group in comparison with patients with no steroid therapy. Also in steroid administration group, OC value was below 8.4ng/mℓ in all patients. Thus, it was suspected that the suppression of bone formation was related to the mechanism of osteoporosis induced by steroid. Then, the further studies on the relationship of BMD and these biochemical parameters including those of younger cases were considered necessary to clarify the mechanism of osteoporosis.

Abstract Cellular composition of bronchoalveolar lavage (BAL) fluid was compared between two age-matched steroid-dependent intractable asthma (SDIA) groups : 17 group A patients (serum IgG level < 1000mg/dℓ) whose immunity was regarded as being suppressed by long-term glucocorticoid therapy and 17 group B patients (serum IgG level > 1200mg/dℓ). 1. The levels of serum IgA and IgM were significantly decreased in group A compared to the levels in group B patients. 2. The number of blood lymphocytes was also significantly lower in group A than in group B patients. However, the number of blood neutrophils was not different between the two asthma groups. 3.The number of BAL lymphocytes was significantly lower in group A than in group B patients. 4. BAL neutrophilia (more than 1.5×10 (4)/mℓ) was observed in 6 of the 17(35.3%) patients in group A, but not observed in any patients in group B. The number of BAL neutrophils was significantly greater in group A than in group B patients. These results suggest that there is a correlation between immunosuppression by glucocorticoids and BAL neutrophilia in patients with bronchial asthma.

Abstract Humoral and cellular immune responses in bronchial asthma were examined by comparing the results of older asthmatics (group OA) with those of older healthy subjects (group OH) and of younger asthmatics (group YA). In humoral immune response, IgE-mediated immune system expressed by elevated serum IgE levels and IgE antibodies for house dust mite (HDm) and/or Candida albicans was clearly found in older asthmatics, while there was no finding showing the presence of IgE-mediated immune response in older healthy subjects. There was no significant difference in levels of serum IgG and IgA among the three groups. However, the serum IgM level was significantly lower in older asthmatics than in younger asthmatics. IgE antibodies to HDm and/or Candida albicans were more frequently found in older asthmatics compared with older healthy subjects. In contrast, IgG(4) antibodies to HDm were not different among the three groups. IgG(4) antibodies to Candida albicans were significantly higher in both older groups than in younger group. However, there was no significant difference between asthmatic and healthy subjects in the elderly. Delayed skin reaction to PPD was significantly more decreased in older asthmatics. These results show that bronchial asthma in the elderly is characterized by the presence of IgE-mediated immune response and by the changes of immune response with aging.
Abstract Alternative 気管支喘息における液性および細胞性免疫反応について,老年者気管支喘息,老年者健常人,および若年者気管支喘息の間で比較検討を行った。1.まず,液性免疫では,血清IgE値高値,ハウスダストやカンジダに対するIgE抗体陽性などのIgE系反応は,老年者気管支喘息においては明らかに観察されたが,老年者健常人では全く観察されなかった。血清IgGおよびIgA値には3者間に有意の差は見られなかったが,血清IgMは,若年者喘息に比べ老年者喘息で有意に低い値を示した。2.ハウスダストやカンジダに対するIgE抗体は老年者喘息において老年者健常人に比べより高い頻度で陽性であったが,一方,ハウスダストに対するIgG(4)抗体は3者聞に有意の差は見られなかった。また,カンジダに対するIgG(4)抗体は,老年者喘息および健常人において,若年者喘息に比べ有意の高値を示した。しかし,老年者の喘息と健常人との間には有意の差は見られなかった。3.PPDによる遅延型皮膚反応は,若年者喘息に比べ老年者喘息において有意の減弱傾向を示した。これらの結果は,老年者喘息はIgE系反応を有していること,そして,加齢による免疫反応の変化の影響を受けること,を示している。

Abstract Serum IgE levels and IgE antibody values in relation to patient age were examined in 50 patients with house dust mite (HDm) sensitive asthma, 1. IgE antibody values to HDm were highest in patients between the ages of 10 and 19, and the values generally low in those over the age of 40. 2. High IgE antibody values to HDm were accompanied by high serum IgE levels in patients between 10 and 19. IgE antibody values and serum IgE levels were in general low in patients over age 40. In patient under age 9, serum IgE levels were less than 500 IU/ml in 5 of the 10 subjects despite an increased value of IgE antibodies to HDm. These results suggest that an increased production of IgE antibodies to HDm is usually accompanied by an increased production of total IgE in younger subjects. However, an increase in production of IgE antibodies is not always related to an increase in production of total IgE in patients under age 9. The results also show that production of IgE antibodies to HDm and total IgE is in general low in older patients despite the hyperreactivity to HDm.
Abstract Alternative ハウスダストが原因抗原であるアトピー型気管支喘息50例を対象に,血清IgE値とIgE抗体価を年齢との関連のもとに検討した。1.IgE抗体価は10-19才の年齢層の症例において最も高く,一方40才以上の症例では全般的に低い傾向が見られた。2.10-19才の年齢層の症例では,IgE抗体価の高値と同時に血清IgE値も高い値を示したが,40才以上の症例では,IgE抗休価および血清IgE値いずれも10-19才の症例に比べ全般的に低い値を示した。9才以下の症例では,IgE抗体価の高値にもかかわらず,血清IgE値は比較的低く,500IU/ml以下を示した症例が10例中5例に観察された。これらの結果は,若年症例では,IgE抗体の産生亢進と総IgEの産生亢進が同時に見られること が多いが,9才以下ではIgE抗体産生亢進に総IgE産生亢進が必ずしもともなわない場合があることを示している。また,40才以上の症例では,ハウスダストに対する過敏性は有しているものの,IgE抗体価および血清IgEは全般的に低い値を示す傾向が示唆された。

Abstract Ventilatory function, cellular composition in bronchoalveolar lavage (BAL) fluid and release of chemical mediators from leucocytes were examined in 25 older asthmatics (mean age 66.7 years) and 25 younger asthmatics (mean age 45.1 years) in relation to clinical asthma types. 1. Ventilatory function tests showed that the values of ventilatory parameters such as % MMF, % V(50) and % V(25) were lower in older subjects than in younger subjects, and a significant difference was found in the % V(50) value between the two age groups. Regarding clinical asthma types, the values of % MMF, % V(50), and V(25) were significantly lower in both younger and older subjects with type II. 2. In analysis of cellular composition in BAL fluid, the proportion of BAL lymphocytes was significantly lower in type II older subjects than in younger subjects with the same type. A significantly increased proportion of BAL neutrophils was observed in both younger and older subjects with type II. 3. The release of leukotriene C(4) (LTC(4)) from leucocytes was significantly lower in type II older subjects than in younger subjects with the same type, and LTC(4) release in patients with type II was also significantly lower than that in those with other asthma types in both younger and older subjects. The release of histamine and leukotriene B(4) (LTB(4)) from leucocytes was not significantly different between the two age groups. These results demonstrate that ventilatory function, cellular composition in BAL fluid, and the release of chemical mediators from leucocytes are affected by aging and clinical asthma types.
Abstract Alternative 25例の老年者気管支喘息と25例の若壮年者喘息症例を対象に,換気機能,気道内細胞成分の頻度,白血球からの化学伝達物質遊離などの気道反応と関連した要素について,喘息の臨床病型との関連のもとに検討を加えた。 1. % MMF, % V(50), % V(25)などの換気パラメーターは老年症例において全般的に低く, % V(50)では若壮年症例に比べ有意の低値を示した。臨床病型別では,II型喘息において,両年齢群とも他の病型に比べ% MMF, % V(50)及び% V(25)値は有意に低い傾向が見られた。 2. 気管支肺胞洗浄(BAL)液中のリンパ球頻度は,II型の老年症例において若壮年症例に比べ有意に低い値を示した。BAL液中好中球頻度は,いずれの年齢群においても,他の病型に比べ有意に高い値を示した。 3. 白血球からのLTC(4)遊離は,II型の老年症例において若壮年症例に比べ,また他の臨床病型に比べ有意に低い値を示した。ヒスタミンおよびLTB(4)遊離には両年歯群間に有意の差は見られなかった。これらの結果は,換気機能,気道内細胞成分の頻度,白血球からの化学伝達物質遊離などが,加齢や臨床病態により影響を受けることをある程度示しているものと考えられた。

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 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 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。

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 Alternative 気管支喘息95例を対象に,MASTシステムにより吸入抗原,食餌抗原の陽性率を検討した。その結果,吸入抗原の方が食餌抗原よりも陽性者が高率にみられ,さらに複数個の抗原に陽性の傾向が見られた。また8名の食餌抗原陽性者の内7名が吸入抗原陽性であった。MAST陽性率と年令,発症年令には食餌抗原では明らかな相関は見られなかったが,吸入抗原では,50才以下の症例に陽性率がやや高い傾向が,発症年令が60才以下の症例の陽性率が高い傾向が見られた。食餌抗原では血清IgE値が300IU/ml以上の症例で陽性者がみられ,1001IU/ml以上の症例では66.7%と比較的高率であった。一方,吸入抗原に対する陽性率は,血清IgE値が500IU/ml以上の症例で高く70%以上の陽性率であった。以上の結果より1検体同時多項目(16項目)測定可能なMASTシステムは従来のRASTに比して臨床的に有用であると考えられた。

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 Alternative 気管支喘息55例(老年症例-65才以上-25例,若年症例-59才以下-30例)における換気機能の特徴について,各臨床病型別に検討を加えた。1.まず対象症例の臨床病型の病態的特徴を,気管支肺胞洗浄(BAL)液中の細胞成分で検討 すると,Ⅱの細気管支閉塞型の症例では,好中球の増加が,またIa-2やIbの過分泌型の症例では好酸球の増加が特徴的であった。2.% FVC,FEVL(1.0%),% PEFRなどの換気パラメーターは,Ⅱ型において他の病型に比べ低値を示す傾向は見られたが,各病型間に有意差は見られなかった。3.% MMF,% V(50),% V(25)などのどちらかと言えば小ないし細気管支領域の換気障害を示す換気パラメーターの値は,老年および若年症例ともⅡ型(細気管支閉塞型)において最も低い値が示された。そして,若年症例では,Ⅱ型の症例においてこれからの換気パラメーターの値は,Ia-1型(単純性気管支攣縮型)に比べ有意に低い値を示した。しかし,老年症例ではⅡ型におけるこれらの換気パラメータ-の値は,他の臨床病型との問に有意の差は見られなかった。

Abstract Characteristics of each asthma type classified by clinical symptoms and findings were studied in 72 patients with bronchial asthma. 1. Ventilatory function tests showed that the values of % MMF, % V(50) and % V(25) were significantly lower in patients with bronchiolar obstruction (type II) compared to the values of those with simple bronchoconstriction type (type Ia) and those with bronchoconstriction + hypersecretion (type Ib). 2. The proportion of neutrophils in bronchoalveolar lavage (BAL) fluid was significantly higher in type II than in type Ia and type Ib. Several patients with type Ib showed higher proportion of BAL eosinophils. 3. The release of LTC(4) from leucocytes was significantly lower in type II compared with type Ia and type Ib. There was no significant difference in the release of histamine and LTB(4) among the three asthma types.
Abstract Alternative 気管支喘息72例を対象に,その臨床病態の特徴を,気道炎症性の細胞および化学伝達物質の観察により検討した。1.気道反応の特徴を換気機能の面から検討すると,II細気管支閉塞型において,MMF,V(50)やV(25)などの小ないし細気管支領域の換気障害を示すパラメーターの値は,Ia型,Ib型に比べ 有意の低下を示した。2.気道細胞反応では,II型において,他の臨床病型に比べ,BAL液中好中球の出現頻度の有意の増加が観察された(Ia, p<0.001 ; Ib, p<0.01)。好酸球の出現頻度は,Ib過分泌型において著しい増加傾向を示す症例が見られたが,その平均出現頻度には3病型間に有意の差は見られなかった。3.好中球からのメジェー夕ー遊離では,ヒスタミン遊離は,Ia単純性気管支撃縮型において最も高い値が示されたが,推計学的には3病型間に有意の差は見られなかった。ロイコトリエンC(4)では,Ia型においてII型に比べ有意に高い遊離が観察された(p<0.05)。ロイコトリエンB(4)遊離には,3病型間に差は見られなかった。

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 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 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。
