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 Twenty six patients with bronchial asthma was classified by clinical symptoms and singns (clinical diagnosis), and the classification by clinical diagnosis was compared with the classification by a score calculated from clinical findings and examinations (score diagnosis). 1. Of 12 subjects with type Ia classified by clinical diagnosis, 8 cases with 0 to 49 ml/day of expectoration were evaluated as type Ia by score diagnosis. While four type Ia cases with 50 to 99ml/day of expectoration were calssified as type Ib by score diagnosis. The increased incidence of eosinophils in bronchoalveolar lavage fluid (BALF) of these four cases was similar to the incidence in type Ib cases with hypersecretion. 2. All of 6 subjects with type Ib by clinical diagnosis were estimated as type Ib by score diagnosis. 3. Of 8 cases with type II by clinical diagnosis, 7 cases were assessed as type II by score diagnosis. One case with type II by clinical diagnosis and with the score of 10 points was evaluated as questionable type II by score diagnosis.
Abstract Alternative 気管支喘息36例を対象に,臨床病態による喘息の分類(臨床診断)を試み,この分類と臨床所見および臨床検査より求めたスコアーによる分類(スコアー分類)との比較検討を行った。1.臨床分類でIa.単純性気管支攣縮型と診断された12症例のうち,1日喀痰量0-49mlの8症例は,スコアー分類では同様にIa.型と分類された。一方,1日喀痰量50-99mlの4症例はスコアー分類ではIb.型(気管支攣縮+過分泌型)と分類された。これら4症例のBALF中好酸球増多はIb.型に類似した病態であった。2.臨床診断によりIb.型に分類された6症例はいずれもスコアー診断でもIb.型と分類された。3.臨床診断によりII.型(細気管支閉塞型)と分類された8症例のうち,7症例はスコアー診断でもII.型と分類されたが,1症例はスコアー10でII.型の診断基準に合わず,questionable II.型と診断された。

Abstract Specific IgG and IgG(4) antibodies against Canadida albicans were exmined in 48 healthy and 69 asthmatic subjects to analyze the mechanism causing an increased production of these immunoglobulins. 1. The level of C.albicans-specific IgG and IgG(4) antibodies was higher, not significantly in IgG(4), in asthmatics under 30 years of age, compared with healthy subjects of the same age group. 2. Specific IgG and IgG(4) antibody levels in both healthy and asthmatic subjects showed a tendency to increase with aging, and significant difference was present between cases under 30 years and cases over 70 years of age. 3. Any difference in the production of specific IgG and IgG(4) was not observed in elderly cases older than 60 years between healthy and asthmatic subjects.
Abstract Alternative 高齢者(61才以上)の健常人48名および気管支喘息患者69例を対象に,カンジダ特異的IgGおよびIgG(4)抗体を測定し,その増加の機序について若干の検討を加えた。なお,対照としては,30才以下の健常者および気管支喘息患者を選んだ。1.カンジダ特異的IgGおよびIgG(4)抗体価は,30才以下では,健常人に比べ気管支喘息症例で高い傾向が見られ,特異的IgG抗体では両者間に有意の差が見られた(p<0.05)。2.カンジダ特異的IgGおよびIgG(4)抗体は,健常人および気管支喘息症例いずれも加齢とともに増加する傾向が見られ,71才では,30才以下の症例に比べ有意に高い抗体価を示した。3.61才以上の高齢者では,特異的IgG,IgG(4)抗体いずれにおいても,健常人と気管支喘息患者との間に有意の差は見られなかった。

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 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 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 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 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 Clinical course of one asthma patient (64 years old, female), who had an increased proportion of neutrophils in bronchoalveolar lavage (BAL) fluid, was observed in relation to the proportion of BAL cells and ventilatory function. The patient had large asthma attacks two times during her clinical course for 15 months observed. 1. An increased proportion of BAL neutrophils and suppression of ventilatory function were found after her first large asthma attacks. The increased proportion of BAL neutrophils continued for more than 5 months. A reduction in the proportion of BAL neutrophils was found 3 months after her second large asthma attack, accompanied by improvement of clinical symptoms and ventilatory function. The numbers of total cells and neutrophils in BAL fluid were also reduced. Transient increase in number of BAL lymphocytes was found 13 months after the first large attack when the number of BAL neutrophils was markedly decreased. The number of BAL eosinophils did not change during her clinical course.
Abstract Alternative 経過中に気管支肺胞洗浄(BAL)液中に一過性の好中球増多が観察されたアトピー型喘息症例について,若干の臨床的観察を加えた。症例は,64才の女性で,臨床症状,および血清IgE高値,ハウスダストに対するIgE抗体陽性などから,アトピー型喘息と診断された。なお,経過観察し得た15ヵ月の間に2回の大発作が観察された。1.第1回の大発作後,BAL液中好中球増多と換気機能の低下が観察された。そして,このBAL液中好中球頻度は明らかな改善が見られた。BAL液中の総細胞数および好中球の絶対数も徐々に減少傾向を示し,好中球頻度と同様,第2回目の大発作3ヵ月後には著明な減少が観察された。同時にこの時期には,BAL液中リンパ球の増加も見られた。しかし,BAL液中好酸球数は15ヵ月の経過観察中ほとんど変化は見られなかった。

Abstract The serum levels of total IgE, IgG and IgG(4) were compared among five age groups of patients with bronchial asthma. 1. The level of serum IgE was significantly higher in the patients before the age of 29 than in those between the ages of 30 and 49 (p < 0.02), between 50 and 59 (p < 0.01) and between 60 and 69 (p < 0.01). The serum IgE level tended to increase in the patients over age 70. 2. The serum level of total IgG was significantly higher in the patients over age 70 compared with the level in the 30-49 (p < 0.05) and the 60-69 year old groups (p < 0.05). 3. The serum IgG(4) level was increased with aging, although no significant difference was found among the five age groups. 4. The IgG(4) level correlated to a certain extent with the level of serum IgE. The results reveal that the levels of total IgE, IgG and IgG(4) are increased in the elderly patients over age 70, and that there is a relationship between serum levels of total IgE and IgG(4).

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 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 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 27~85才の女性143例における骨塩量を,定量的QCT法 (quantitative computed tomography)を用いて測定し,年令,身長,体重及び原疾患(慢性関節リウマチ),使用薬剤(ステロイド・骨強化剤)の因子の骨塩量に及ぼす影響について検討した。その結果,1)加令とともに骨塩量は低下するが,特に40才代後半から60才代にかけての低下が顕著であり,また, 他因子の影響を受けやすい。2)体型的因子としては.痩せ型で低身長の人に低値の傾向がある。3)ステロイド使用の有無における検討において,特に50才代で使用群が著明に低値であることが明らかとなった。また,薬剤の因子の考察に関しては,さらに経時的検討か必要であると思われた。
Abstract Alternative Bone mineral density (BMD) was measured in 143 females aged 27 to 85 years old to investigate the correlations between BMD and several factors such as age, height, presence of rheumatoid arthritis and corticosteroid or bone intensifying drug therapy. 1) BMD values decreased with aglng and the most remarkable decrease was observed at the age of latter half of 40's to 60's. 2) Women with slim and low stature tended to have low BMD values. 3) BMD values of women with steroid therapy were significantry lower than those without corticosteroid at the age of 50's (p<0.01). However, further study is necessary to confirm the effect of drugs on BMD.

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 was compared between two age-matched asthma groups : group A (study group) consists of 8 patients with bronchial asthma with marked neutrophilia (20% or more) in the BAL fluid and group B (control group) of 8 patients with neutrophils (less than 5% of total BAL cells). The values of six ventilatory parameters were lower in group A than in group B, and a significant difference was found in FEV(1.0%), % MMF, % V(50) and % V(25) between groups A and B. Of these parameters, the value of % V(25) was markedly decreased in group A compared with group B. The results show that ventilatory dysfunction in airways, especially in small airways, is closely correlated to increased number of neutrophils in BAL fluid.

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 A correlation between the proportion of eosinophils in bronochoalveolar lavage (BAL) fluid and amount of expectoration was examined in patients with atopic asthma. The subjects were divided into two groups : cases with high proportion (20% of more) (group A) and low proportion (less than 5%) (group B) of eosinophils in the BAL fluid. Any significant difference was not paesent in the value of each ventilatory parameter between the two groups. The amount of expectoration/day was significantly higher in group A compared with group B (p<0.001). These results suggest that eosinophilia in BAL fluid correlates to mucus hypersecretion in the airways of patients with atopic asthma.

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。
