Abstract N-3系脂肪酸の気管支喘息に対する有用性が示唆されているが,その評価は定まっていない。今回,5人の気管支喘息患者に対しN-3系脂肪酸であるαリノレン酸を豊富に含有するエゴマ油を用いた食事療法を行い,臨床症状,ピークフロー値,末梢白血球からのロイコトリエン産生能,血漿リン脂質中の脂肪酸組成につき検討を行った。2週間の食事療法の前後でピークフロー値は有意な改善を示し(p<0.05),カルシウムイオノファー刺激によるロイコトリエン(LT)産生能は治療前後でLTB4が77.6ng/5×106cellsから41.6ng/5×10(6)cells(p<0.05)に,LTC4は64.0ng/5×10(6)cellsから38・8ng/5×10(6)cells(p<0.05)とともに有意な改善を認めた。また血漿リン脂質中のN-3系脂肪酸(αリノレン酸,エイコサペンタエン酸,ドコサヘキサエン酸)も有意な上昇を認めた。以上よりN-3系脂肪酸(エゴマ油)を用いた食事療法の有用性が示唆された。
Abstract Alternative The therapeutic trials using N-3 fatty acids such as fish oil have been reported in patients with bronchial asthma, while its effect is still controversial. The effects of dietary supplementation with perilla seed oil rich in alpha-linolenic acid (α-LNA), parent n-3 fatty acid, were studied in five patients with asthma. The symptoms of asthma and mean peak flow rates (PFR) both early in the morning and in the evening were improved 2 weeks after the dietary supplementation and the increases of peak flow rates were significant (p<0.05). The generation of leukotriene B4 (LB4) by peripheral leukocytes stimulated with Ca ionophore A23187 was significantly suppressed from 77.6 ng/5×10(6) cells to 41.6ng/5×10(6) cells by the supplementation (P<0.05). The generation of leukotriene C4 (LTC4) by leukocytes was also significantly suppressed from 64.0 ng/5×10(6) cells to 38.8ng/5×10(6) cells after the manipulation with perilla seed oil (P<0.05). The concentration of N-3 fatty acids (such as α-LNA, eicosapentaenoic, and docosahekisaenoic acids) in plasma phospholipid increased significantly after the dietary supplementation (P<0.05). These results suggest that dietary supplementation with perilla seed oil is beneficial for the treatment of asthma.

Abstract Extent of nasal and maxillary mucosa lesion was estimated in 26 asthmatics using computed tomographic scan in relation to clinical features of the disease. 1. No significant differences were present in nasal mucosal thickening between atopic and non-atopic subjects. No significant differences were also present in occupancy rate of mucosa in maxillary sinuses between the two asthma types. 2. Nasal mucosal thickening was not significant different between subjects with steroid-dependent intractable asthma (SDIA) and those without SDIA. Maxillary mucosal lesions were more extensive in subjects with SDIA than in those without SOIA. However, no significant differences were observed in occupancy rate between the two types. 3. No significant differences were observed in nasal mucosal thickenings between in subjects with and without aspirin-induced asthma (AlA). Although maxillary mucosa lesion in subjects with AlA was more extensive than that in those without AlA, the differences was not significant. 4. There was not any correlation between nasal mucosal thickening and amount of expectoration per day. However, significant differences were observed in maxillary sinus lesion between subjects with less amount (<50mℓ/day) and those with large amount of expectoration (100mℓ/day≦)(p<0.002), and between subjects with moderate amount (50-99mℓ/ day) and those with large amount of expectoration (p<0.002). The results might suggest that in asthmatics with large amount of expectoration, sinus diseases affect pathophysiology of asthma, and asthmatics with large amount of expectoration should have therapy for sinus disease to improve asthmatic status.
Abstract Alternative 気管支喘息26症例において喘息の臨床的特徴と,鼻腔・上顎洞のCT所見の関連について検討を加えた。1.鼻腔粘膜肥厚はアトピー症例,非アトピー症例間で有意な差は認められなかった。上顎洞における粘膜肥厚比率(1slice上の上顎洞面積に対し,上顎洞粘膜が占める割合)も,アトピー・非アトピーで差は認められなかった。2.ステロイド依存群・非依存群においても,鼻腔粘膜肥厚・上顎洞粘膜肥厚に有意な差は認められなかった。3.アスピリン喘息症例においては,非アスピリン喘息症例に比べ,上顎洞粘膜肥厚が顕著であっ たが有意ではなかった。鼻腔粘膜肥厚は2群間で差は認められなかった。4.発作時の一日喀痰量との関連では一日喀痰量が100mℓ以上の症例群では,喀痰量が50mℓ以下の群・50-100mℓの群に比較して有意に上顎洞粘膜肥厚比率が高値を示した。鼻腔粘膜比率に関しては3群間で有意な差を認めなかった。以上の結果から,喀痰量の多い気管支喘息症例では,その病態に副鼻腔病変が影響を及ぼしている可能性が考えられ,副鼻腔病変に対する治療により,気管支喘息が改善する可能性が考えられた。

Abstract 気管支喘息に対する温泉療法の効果をピークフローメーターを用いて継時的(第1週,第5過,第9週)に検討した。1.軽症・中等症では,第5週で有意にピークフロー (PEF)値は上昇した.重症気管支喘息例では第9週に有意な改善を認めた。2.20%以上のPEF値の改善を認めた症例の割合は第5週では,軽症・中等症・重症群で40~50%であったが,第9週では軽症群で80%,重症群で54.5%に増加していた。中等症群では第5週と同等であった。3.第1週のPEFが200(L/m)以下の症例では第5週,第9過とPEFの有意な改善を示したが,200<PEF≦300の症例,300<PEFの症例では有意な改善は認められなかった。4.PEF≦200(L/m)の症例群において,20%以上のPEFの改善を示す症例は,第5週で57%,第9週で69%と高率であった。200<PEF≦300の症群,300PEFの症例群では第9週で40%以上の症例が20%以上のPEFの改善を示した。
Abstract Alternative The aim of this study was to investigate effects of spa therapy on peak expiratory flow (PEF) in patients with bronchial asthma. Morning PEF metry was studied in fifty asthmatics who had spa therapy (swimming training in a hot spring pool, inhalation of iodine salt solution and fango therapy) for 5 - 9 weeks. Mean values of morning PEF at the initial stage, 5 and 9 weeks after spa therapy were assessed. In mild and moderate asthmatics, PEF significantly improved 5 weeks after spa therapy. In severe asthmatics, PEF showed significant increase 9 week. The number of subjects with PEF improvement more over 20%, compared with the intial value of PEF, were 50% at 5 weeks and 80% at 9 weeks after spa therapy in mild asthmatics. In moderate asthmatics, however, the number little changed between 5 (39.3%) and 9 weeks (38.9%) after the therapy. In severe asthmatics, 57.1% at 5 and 68.8% at 9 weeks. In asthmatics with the initial value of PEF<200L/m (low PEF group), the value showed significant increase 5 and 9 weeks after the therapy compared with the initial value. In asthmatics with the initial values of 200≦PEF<300 (middle PEF group) and 300≦PEF (high PEF group), the values showed no significant increase. The number of subjects with PEF improvement more than 20% showed a tendency to increase 9 weeks in low, middle and high PEF group, compared to the value after spa therapy (57.1% to 68.8%, 21.4% to 50% and 35.7% to 42.9%, respectively ).

Abstract The maximal percent low attenuation area < -950 HU (% LAA) among three anatomic lung levels on high resolution computed tomography (HRCT) was examined in patients with asthma, classified by the degree of % LAA, in relation to the mean CT number, % FVC of the predicted value, and FEV 1/FVC (FEV1%). 1 . The mean CT number was closely related to the degree of % LAA of the lungs. The mean CT number was significantly lower in patients with high % LAA (mean CT number-915.3HU, % LAA 37.6%) than in those with low % LAA (-852.9HU, 4.7%). 2. The FEV1% value was significantly lower in patients with high % LAA (47.8%) than in those with low % LAA (62.2%)(p<0.05). The % FVC value was also significantly lower in patients with high % LAA (77.1%) compared to the value in those with low % LAA (101.2%). The results suggest that a large volume of LAA<-950HU of the lungs can be observed in patients with asthma, and the % LAA is closely correlated with mean CT number and the values of FEV1% and % FVC.
Abstract Alternative HRCT (high resolution computed tomography)により,-950HU以下のlow attenuation area(LAA)を3つの高さの肺野レベルで観察し,そのなかの最も高い値をmaximal% LAAとして表し,この値と平均CT number, % FVCおよびFEV1.0%の値と比較検討した。1.平均CT numberは,maximal% LAAと密接な関連を示した。そして,平均CT numberは,% LAAが低い症例(% LAA :4.7%, mean CT number:-852.9HU)に比べ,% LAAが高い症例(% LAA :37.6%, mean CT number:-915.3HU)において低い傾向が見られた。2.FEV1.0%値は,% LAA値が低い症例(62.2%)に比べ% LAA値が高い症例(47.8%)において有意に低い値を示した(P<0.05)。% FVC値も同様% LAA値が低い症例(101.2%)に比べ高い症例(77.1%)で低い値を示したが両群間に有意の差は見られなかった。これらの結果より,気管支喘息においも,HRCT上肺野で-950HU以下のLow attenuation area(LAA)を示す症例が見られること,そして,% LAAは,mean CT number,FEV1.0%や% FVC値とある程度関連していることが示唆された。

Abstract The percentage of attenuation area < -950HU (% LAA) on high resolution computed tomography (HRCT) was compared between 17 smoking and 24 nonsmoking patients with asthma. 1. FEV1/FVC value was lower in smoking patients (56.4%) than in nonsmoking patients (66.0%), however, the difference was not significant. 2. The percentage of LAA of the lung was larger in smoking patients compared with that in nonsmoking patients in all the three anatomic levels: the % LAA was 14.4% in nonsmoking and 20.3% in smoking patients at lower lung level (3cm above the top of the diaphragm). However, this was not significant. The maximal % LAA among the three lung levels on HRCT was 21.6±12.5% in smoking, and 15.7±11.9% in nonsmoking patients. This suggested that the maximal % LAA was larger in smoking patients, however, this was not significant. 3. The mean CT number of the lung on HRCT was smaller in smoking patients (-897.3HU) than in nonsmoking patients (-884.7HU). 4. Three of 4 nonsmoking patients whose % LAA was more than 30% had severe intractable asthma with long-term glucocorticoid therapy. The results suggest the possibility that smoking influences the % LAA of the lung on HRCT in asthma. It could be also speculated that % LAA is influenced by severity of asthma.
Abstract Alternative HRCT (high resolution computed tomography)による-950HU以下の肺野のlow attenuation area(LAA)について,17例の喫煙喘息症例と24例の非喫煙喘息症例で比較検討した。1.FEV1.0%値は,喫煙症例(56.4%)で非喫煙症例(66.0%)に比べ低い値が示されたが,両群間に有意の差は見られなかった。2.% LAAは,肺野のいずれの高さにおいても,非喫煙症例に比べ喫煙症例で高い傾向が見られたが,有意の差ではなかった。Maximal % LAAは,喫煙症例で21.6%,非喫煙症例15.7%であり,同様に喫煙症例で高い傾向が見られたが,有意の差は見られなかった。3.平均CT値は,非喫煙症例(-884.7HU)に比べ,喫煙症例(-897.3HU)で低い値であった。4.% LAAが30%以上を示 す4例の非喫煙症例のうち,3例がステロイド依存性の重症難治性喘息であった。これらの結果より,喫煙が肺野の% LAAに影響をあたえる可能性もあるものの,疾患の重症度がより影響が強い可能性が示唆された。

Abstract Alternative The kind of respiratory diseases, age, and areas where patients came from were discussed in 520 patients with chronic obstructive pulmonary diseas (COPD) admitted at Misasa Medical Branch for last 5 years from 1992 to 1995. 1. For the last 5 years 588 patients with respiratory diseases were admitted at Misasa Medical Branch. Of these patients, 520 were those with chronic obstructive pulmonary disease (COPD). Of the 520, 433 (83.3%) were patients with asthma" 19 with chronic bronchitis, 33 with obstructive bronchiolitis, and 35 with pulmonary emphysema. 2. Regarding the distribution of age of these patients, patients between the ages of 60 and 69, and those over the age of 70 were more frequently observed, regardless of the area where patients came from (inside or outside Tottori prefecture). 3. The number of patients from distant areas (outside Tottori prefecture) was larger than the number of those inside Tottori prefecture. The number of patients from Okayama, Hyogo, Hiroshima, Osaka, Yamaguchi, and Ehime prefectures was predominantly larger than the number from other distant areas.

Abstract IgE antibodies against inhalant allergens were estimated in 53 patients with bronchial asthma in relation to allergic rhinitis. Of them, 20 patients (37.7%) had allergic rhinitis. 1. Asthma + allergic rhinitis were often observed in patients between the ages of 0 and 39. In contrast, asthma alone in those over age 60. 2. A RAST score was positive in house dust mite (HDm)(50.9%), cockroach(24.5%), and Candida (26.4%) in these patients, and the positive rate was not different between patients with and without allergic rhinitis. 3. The frequency of positive RAST against Japanese cedar and rice plants was higher in patients with allergic rhinitis (42.9% and 18.5%) than in those without allergic rhinitis (28.6 and 3.7%), however, the each positive rate or RAST against the two allergens was not significantly different between those with AR and without AR. 4. The number of patients with AR induced by pollen alone (pollinosis) was not large ( 5/53, 9.4%) in the patients with asthma. It was clarified from the results that allergic rhinitis was often observed in asthma patients, but not pollinosis. and that IgE antibodies against Japanese cedar and rice plants were found even in patients without AR.
Abstract Alternative 気管支喘息53例を対象に,吸入抗原に対するIgE抗体とアレルギー性鼻炎の合併の有無との関連について若干の検討を加えた。対象53例中20例(37.7%)にアレルギー性鼻炎の合併が見られた。 1.喘息+アレルギー性鼻炎の合併は,0-39才の年齢層で最も多い傾向であったが,一方,喘息単独は60才以上の症例に多く見られた。2,IgE抗体の陽性率は,それぞれHDm50.9%,ごきぶり 24.5%,カンジダ26.4%であった。これら抗原のRAST陽性率は,アレルギー性鼻炎合併例と非合併例の問に有意の差は見られなかった。3.スギおよびイネ科の花粉に対するRAST陽性率はアレルギー性鼻炎合併例で(スギ42.9%,イネ科18.5%),非合併例に比べ(28.6%と3.7%)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。4.花粉抗原によるアレルギー性鼻炎(花粉症)の頻度は9.4% (53例中5列)とあまり高くはなかった。以上の結果より,気管支喘息患者でしばしばアレルギー性鼻炎の合併が見られること,(しかし, 花粉症は少ない),そして,スギおよびイネ科の花粉に対するIgE抗体は,アレルギー性鼻炎の合併のない症例においても観察されること,などが明らかにされた。

Abstract Recent advances in molecular biology have revealed that a number of oncogenes (K-ras, erbB-2, and Met) and tumor suppressor genes (p53, p16, APC, and DCC) contribute to the development of pancreatic cancer. This paper reviewed the present knowledge of oncogenes and tumor suppressor genes relevant to pancreatic cancer. Further studies on molecular alterations in pancreatic cancer may lead to a better understanding of tumor biology, offering a possibility of development of new diagnostic and therapeutic approaches in the future.

Abstract 近年アトピー性皮膚炎が増加しており,工ゴマ油を使った食事療法がアレルギー抑制に有用であることが報告されている。そこで今回,エゴマ油を外用剤として使用するため,亜鉛華単軟膏を基剤とした工コマ軟膏を作製し,アトピー性皮膚炎患者3例を対象にその臨床応用を試みた。その結果,掻痒感の軽減に効果がみられ,また皮膚症状では,丘疹.表皮剥離,苔癬化,落屑などの所見が改善される傾向が見られた。
Abstract Alternative The perilla seed oil contains rich α-linolenic acid (α-LNA), parent n-3 fatty acid. The dietary intake of n-3 fatty acid, such as perilla seed oil, has been reported to have some clinical effects in patients with allergic disease. In this report, we prepared the perilla seed oil ointment for atopic dermatitis and the effects of the ointment was evaluated in three patients with atopic dermatitis. This ointment suppressed skin itch, and improved papules, excoriation, lichenification and desquamation of the skin. These results suggest that the perilla seed oil ointment has some effectiveness including suppression of inflammatory changes of the skin in patients with atopic dermatitis.

Abstract The body surface temperature of 41 patients suffering coldness, numbness or pain in their feet was examined using thermography. Thermographic results were analyzed quantitatively by calculating a recovery ratio as: Recovery ratio =[Total counts of thermography (Pixels) over temperature (T) after cold loading] ÷ [Initial counts over T before cold loading] x 100(%). Three different baseline temperatures, 26℃. 27℃ and 28℃, were used in processing the thermographic results into pictures. The recovery ratio was susceptible to temperature, and we recommend a baseline temperature limitation of 27℃ for clinical study. A bi-modal distribution of recovery ratio was observed in 18 patients with diabetes mellitus. One group (6 subjects) had high recovery ratio between 80%-100%, and another group (10 subjects) had a low recovery ratio between 0%-19%. The results of thermography were also influenced by weather. To reduce the effect of outside temperature, we used pre-loading with hot water at 36℃ for 5 min (hot loading). A large difference in recovery ratio between presence and absence of hot loading was observed in 6 of the 30 subjects. The difference was over-estimated in more than 20% of recovery ratio without hot loading as compared with hot loading in these 6 subjects. The effect of drugs on peripheral circulation, such as beraprost sodium and sarpogrelate hydrochloride, was clear and quantified using thermography under these conditions of hot loading.
Abstract Alternative 下肢に冷感ならびにしびれ感または疼痛を訴える患者41症例についてサーモグラフィーを用いて体表面温度を測定した。測定で得られた結果は回復率として数量化して表示された。回復率の算出方法は回復率=[冷水負荷後の特定温度T℃以上の体表面温度のサーモグラフィーのPixelの総数]÷[温水負荷前の特定温度T℃以上の体表面温度のサーモグラフィーのPixelの総数]× 100%で求めた。サーモグラフィーで得られた結果と画像処理の過程で用いられた,26℃,27℃,28℃の3つの異なる特定温度T℃ との関連について検討を行なった。その結果,回復率は特定温度T℃に影響を受けやすいことが明らかとなった。下肢の体表面温度の低い臨床症例においては27℃の条件が適当と考えられた。前述の41症例中の18症例の糖尿病患者について検討を行なった。そのサーモグラフィーの結果は,比較的回復率の高い(80%~100%)群の6症例と比較的回復率の低い(0%~19%)群の10症例の2群に別れた。わずかに残り2症例が20%から79%の間であった。下肢の症状が気温の低い時期に出親しやすいためにサーモグラフィーの検査を冬期に行なう必要性が高まった。しかし,天候の影響を受けやすいために冷水負荷前の測定領域の下肢が冷えすぎているために20℃の室温に15分間の安静時間では体表面温度が十分に暖まることが出来ず,27℃以上の領域として測定範囲全体を観察できない 問題に直面した。この間温点を解決する手段として36℃の温水に5分間下肢を入れて暖める温水負荷を加えることにした。そこで, 温水負荷を行なった症例30症例について,温水負荷を行なう前(室温)の回復率と温水負荷を行なった後の回復率について比較検討を行なったところ,20%にあたる6症例において温水負荷を行なわなかった場合に20%以上の回復率の過剰評価が認めら れた。温水負荷を行なうことにより年間を通じて天候の影響を最小限にすることが可能となり,この結果,長期間の内服薬の末梢循環に及ぼす影響の測 定を行なった場合に,季節の影響を最小限にしてサーモグラフィーにより回復率を用いて数値化された測定結果を検討することが可能となった。具体的に末梢循環の改善に薬効が有ると言われている薬剤であるベラプロストおよびサルポグレラートを3ヵ月間内服した場合の前後のサーモグラフィーで得られた回復率について検討を行なった。その結果はベラプロストにおいては,6.9%から41.9%に上昇または回復率の6.1倍の上昇を認めた。サルポグレラートにおいては,1.9%から17.3%に上昇または回復率の9.1倍の上昇を認めた。以上より,温水負荷を加えたサーモグラフィーの測定結果の数値化は下肢に症状の有る患者の末梢循環の評価ならびに薬効の評価の比較に有用であることが表わされた。

Abstract Recently, we experienced two asthmatic patients with advanced gastric cancer. The two patients had steroid-dependent intractable asthma (SDIA) who had been on administration of corticosteroids for more than 2 years. To determine the influence of pathophysiology of SDIA on stomach mucous lesion, gastroscopic examinations and immunological examinations were performed in eight patients with SDIA, compared with 25 patient with non-SDIA. In patients with SDIA, gastric cancer, its precursor condition and immunosuppressive state were observed. These results suggest that the immunosuppressive state in SDIA induced by the long-term administration of corticosteroids may lead to the risk of gastric cancer development.
Abstract Alternative 最近,進行胃癌を合併した気管支喘息症例を2例経験した。2症例ともにステロイド依存性重症難治性喘息(SDIA)症例であり,SDIAが胃悪性腫瘍に関与している可能性が考えられた。今回,SDIA症例における胃粘膜病変の臨床像および背景因子を検討する目的で,8例のSDIA症例における胃内視鏡検査,末梢血液分画,免疫グロブリン定量を行い,非SDIA症例と比較検討を行った。SDIA症例においては胃癌・前癌状態が認められたが,非SDIA例では認められなかった。SDIA群において,末梢血白血球は有意に増加し,リンパ球分画・IgGは有意に減少していた。これらの結果より,ステロイド依存性重症難治性気管 支喘息症例においては免疫状態が抑制され,胃悪性腫瘍が発生する危険性があるものと考えられた。

Abstract We experienced a case of 59-year-old woman with intractable asthma, who had aspirin intolerance. Despite various treatments including systemic corticosteroid administration, she was often admitted due to severe asthma attacks. Furthermore, she had allergic rhinitis and sinusitis. Computed tomography (CT) scans of sinonasal cavity revealed marked thickness of nasal mucosa and air-fluid level in maxillary sinuses. Although her asthma symptoms such as wheezing and dyspnea were improved by administration of bronchodilator, systemic corticosteroids and beclomethasone diisoccyanate (BDI) accompanied with spa therapy, her peak expiratory flow (PEF) showed no improvement. After readmission due to asthma attacks, clarithromycin (CAM) administration for sinonasal disorders was started. The PEF value showed marked improvement after starting CAM administration, and pulmonary functions and bronchial hyperresponsiveness were also improved. It is suggested from her clinical course that CAM may have beneficial effects in asthmatic patients with sinonasal disorders.
Abstract Alternative 気管支喘息にアレルギー性鼻炎や副鼻腔炎を合併する症例は頻回に経験される。副鼻腔炎症状の増悪が喘息症状の増悪を引き起こす症例も存在し,鼻腔・副鼻腔における炎症が気管支喘息の病態と何らかの関係を持っていることが考えられる。今回,59才の難治性アスピリン喘息症例を呈示する。副腎皮質ホルモンの全身投与を含めた様々な治療にも関わらず頻回に重篤な喘息発作を呈し,入退院を繰り返している症例である。アレルギー性鼻炎も合併し,CTでは著明な鼻粘膜肥厚と上顎洞の鏡面形成が認められた。入院後の投薬や温泉療法によって呼吸困難は改善したが,ピークフロー値は上昇が認められないまま退院となった。再入院後,副鼻腔炎に対しクラリスリマイシン投与を開始したところ、ピークフロー値は著明に改善を示し,肺機能・気道過敏性も改善した。この症例のように,鼻腔・副鼻腔疾患を合併する気管支喘息症例に対しては,クラリスロマイシン投与が有効である可能性が考えられた。

Abstract An effective treatment for the advanced stages of chronic obstructive pulmonary disease (COPD) has not been established yet. We report our recent experience of one patient with pulmonary emphysema treated by dietary supplementation of n-3 fatty acid for two months. He presented improvements in clinical symptoms and pulmonary function, and suppression of leukotriene B(4) generation by peripheral leukocytes. We consequently suppose that dietary treatment with n-3 fatty acids (perilla seed oil) may offer benefits for the treatment of pulmonary emphysema by competitively inhiabiting the conversion of arachidonicacid to leukotrienes and prostanoids.
Abstract Alternative 今回我々は,肺気腫の症例に対してn-3系脂肪酸を強化した食事療法をおこない,臨床症状,呼吸機能検査所見ともに速やかに改善を認め,同時に白血球のロイコトリエンB4産生能が著明に減少した一例を経験したので報告する。 症例は67歳,男性。主訴は労作時呼吸困難。【第一回目入院】3カ月間入院し,薬物療法,温泉を用いた理学療法を行った。自覚症状はやや改善が見られたが,呼吸機能検査所見の改善は得られなかった。【第二回目入院】1年後に再入院。n-3系脂肪酸強化食事療法も併用した。自覚症状および,呼吸機能検査上,FVC,FEV1.0,PEFなどに改善を認めた。n-3系脂肪酸はアラキドン酸代謝を通してロイコトリエン合成に関与すると推定されるが,経渦中に白血球のLTB4産生能の減少を認めた。この症例は肺気腫に対するn-3系脂肪酸強化食 事療法の有用性が示唆され,病態を考える上でも興味深いと考えられた。

Abstract N-3 fatty acids, such as fish oil, have been reported to have some beneficial effects in patients with bronchial asthma by suppressing leukocyte function, followed by reduction of the need for pharmacologic agents. To examine the effects of dietary supplementation with perilla seed oil rich in α-linolenic acid (ALA), 23 patients with asthma took corn oil rich in linoleic acid (LA) for the former two weeks, perilla seed oil for the later two weeks. The asthmatic patients were classified into two groups by the changes of the generation of leukotrienes B4 (LTB4), C4 (LTC4), and B5 (LTB5) during the two courses of dietary modification: one was sensitive to dietary modification, and the other was insensitive to dietary supplementation. We compared the two groups in clinical characteristics. Significant differences were observed in peak flow (PEF), forced expiratory volume in one second (FEV1.0), IgE, sex, obesity index (OI), concentration of serum total cholesterol, albumin, low density lipoprotein {LDL)-cholesterol, β-lipoprotein and phospholipids between two groups. This study indicated that these factors influence the generation of LTB4, C4 and B5 of asthmatic patients in dietary supplementation.
Abstract Alternative 気道への炎症性白血球の集合が気管支喘息の病態に関わっている。魚油などのn-3系脂肪酸が白血球の機能を抑制することにより気管支喘息患者に良好な効果をもたらし,薬剤の必要性を減じたとの報告がなされている。α-リレノン酸を豊富に含有するエゴマ油食の効果を調べるため,気管支喘息患者23名に2コースの食事-リノール酸の豊富なコーン油食を2週間摂取後,エゴマ油食を2週間-を摂取してもらった。喘息患者は2コースの食事間のロイコトリエンB4(LTB4),CA(LTC4),B5(LTB5)の変化から2群-1群は食事に対し感受性のある群,もう1つは感受性の無い群-に分類した。我々はこの2群を臨床的に検討したところ,ピークフロー(PEF),1秒量(FEV10),IgE,性別,肥満率(OⅠ),血清総コレステロール,アルブミン,低比重リポ蛋白(LDL)-コレステロール,β-リポ蛋白,リン脂質において2群間に有意差が認められた。今回の研究から,これらの因子が,喘息患者において,LTB4,LTC4,LTB5の産生に対する食事療法の効果に影響を及ぼしていることが示唆された。

Abstract We report a patient who developed giant cell (temporal) arteritis during treatment of rheumatoid arthritis. The patient was a 57-year-old Japanese woman and had been well controlled with anti-rheumatic drugs, when she presented to our hospital with severe bitemporal headaches and marked fatigue. An exclusive diagnosis was rapidly made and she was diagnosed as having giant cell arteritis based on the classification criteria by American College of Reumatology. Additionally, magnetic resonance (MR) angiography was performed, from which stenotic change in the bilateral superficial temporal arteries was strongly suspected and then corticosteroid therapy was quickly started. The patient followed an uneventful course without developing any complications such as visual dysfunctions. Therapeutic effect was confirmed by MR-angiographic findings obtained 4 weeks after the initiation of therapy.

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 To analyze the pathophysiological changes ot the airways in emphysema, bronchial responsiveness and the generation of leukotrienes B4 (LTB4) and C4 (LTC4) by peripheral leucocytes were examined in 22 patients with emphysema. The subjects were divided into two groups according to the presence or absence of IgE antibodies against inhalant allergens; RAST positive group and RAST negative group. 1. Smoking history, mean CT number and mean maximum % low attenuation area (% LAA) <-950HU of the lung on high resolution computed tomography (HRCT), and DLco value suggested that there were emphysematous changes of the lung in all subjects. However, these findings were not different between the two groups. 2. The level of serum IgE was significantly higher in RAST positive group than in RAST negative group. 3. The mean % increase in FEV1.0 after inhalation of β-agonists was higher in RAST positive group than in RAST negative group. The % increase more than 15% was found in 4 of the 9 subjects (44.4%) in RAST positive group and 2 of the 12 (16.7%) in RAST negative group. 4. The generation of LTC4 by leucocytes was significantly higher in RAST positive group than in RAST negative group (p<0.01). The generation of LTB4 was not significantly different between the two groups. The results suggest that IgE-mediated allergy participates in the bronchial responsiveness of patients with emphysema.
Abstract Alternative 肺気腫患者の気道病変を解析する目的で,22例の肺気腫患者を対象に,その気道反応および白血球のロイコトリエンB4,C4産生能について検討を加えた。この際対象症例はIgE抗体の有無によってRAST陽性症例RAST陰性症例に分類された。1.喫煙歴,平均CT値,high resolution computed tomography(HRCT)上の-950HU以下の% low attenuation area(% LAA),DLcoなどの値は,いずれも対象症例が高度な気腫化病変を有してい ることを示した。2.血清IgE値は,RAST陽性例で陰性例に比べ有意の高値を示した。3.β受容体刺激薬吸入後のFEV1.0の増加は,RAST陽性例で陰性例に比べ高度であった。そして,吸入後のFEV1.0が15%以上の増加を示した症例は,RAST陽性例では9例中4例(44.4%),陰性例では12例中2例(16,7%)であった。4.白血球のLTC4産生量は,RAST陽性例で陰性例に比べ有意に高い値であったが,LTB4産生は両者間に有意の差は見られなかった。以上の結果より,IgEにmediateされるアレルギー反応が,肺気腫患者 の気道反応に関与している可能性が示唆された。

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 The generation of leukotrienes B4 (LTB4) and C4 (LTC4) by leucocytes stimulated with Ca ionophore A23187 was examined in 16 patients with asthma (8 with atopic and 8 with nonatopic asthma) and 12 healthy controls. 1. The LT84 generation by leucocytes was not significantly different between patients with asthma and healthy controls. The generation of LTC4 was significantly larger in patients with asthma than in healthy controls. The LTC4 generation was also significantly larger in patients with attacks (58.4 ± 38.5 ng/5x10(6) cells) than in those without attacks (23.3 ± 25.9 ng/5x10(6) cells)(p<0.05). 2.ln atopic asthma, the LTC4 production was significantly larger in patients with attacks (84.7 ± 35.4 ng/5x10(6) cells) compared to the production in those without attacks (40.4 ± 27.2 ng/5x10(6) cells)(p<0.02). However, the production of LTB4 was not significantly different between attack and attack-free stages. 3. In nonatopic asthma, the LTC4 production was also significantly higher in patients with attacks (32.2 ± 26.3 ng/5x10(6) cells) than in those without attacks (12.2 ± 3.5 ng/5x10(6) cells)(p<0.05). However, the LTB4 production was not significantly different between attack and nonattack stages. 4. The LTC4 production was significantly larger in atopic asthmatics compared to the production in nonatopic subjects both in attack and nonattack stages. These results suggest that the generation of LTC4 by leucocytes of patients with asthma is closely related to IgE-mediated reaction and asthma attacks.
Abstract Alternative 気管支喘息16例(アトピー型喘息8例,非アトピー型喘息8例)を対象に,Ca ionophore A23187 刺激時の末梢血白血球のロイコトリエンB4(LTB4)およびC4(LTC4)産生能について検討した。1.LTB4産生能は,喘息症例と健康人 の間に有意の差は見られなかった。LTC4産生能は,健康人に比べ喘息症例で有意に高い傾向が見られた。また,喘息症例では,非発作時(23.3±25.9ng/5xl0(6)cells)に比べ発作時(58.4±38.5ng/5xl0(6)cells)に有意に高い値を示した(p<0.05)。アトピー型喘息では,非発作時(40.4±27.2mg/5xl0(6)cells) に比べ発作時(84.7±35.4ng/5xl0(6)cells) に有意の高値を示したが(p<0.02),LTB4 産生に関しては両者間に有意の差は見られなかった。3.非アトピー型喘息においても同様,非発作時(12.2±3.2ng/5xl0(6) cells) に比べ発作時 (32.2±26.3ng/5xl0(6)cells)で有意の高値であったが(P<0.05), LTB4 では有意差は見られなかった。4.LTC4産生能は,発作時、非発作時とも,アトピー型喘息で非アトピー型喘息に比べ有意に高いことが示唆された。以上の結果より,喘息症例における白血球のLTC4産生能はIgE にmediateされる反応と密接な関連がある可能性が示唆された。

Abstract 1993年1月より1997年12月までの5ヵ年間に当院へ入院した慢性閉塞性呼吸器疾患511例を対象に,疾患の種類,年齢,地域分布などについて検討を加えた。1.最近5年間に当院へ入院した呼吸器疾患患者は594例で,このうち,慢性閉塞性呼吸器疾患患者は511例(86.0%)であった。これらの慢性閉塞性呼吸器疾患のなかでは,気管支喘息が416例(81.4%)と最も多く,その他.慢性気管支炎20例,閉塞性細気管支炎27例,肺気腫48例であった。2.慢性閉塞性呼吸器疾患のなかでは,肺気腫の症例が増加する傾向が見られた。3.慢性閉塞性呼吸器疾患の年齢別検討では,鳥取県内では,70才以上の症例が,また遠隔地(鳥取県外)では60-69才の症例の頻度が高い傾向が見られた。4.入院患者の地域分布では,鳥取県内からの入院患者に比べ,遠隔地(鳥取県外)からの入院患者が比較的多く,その比率は1997年度で48.4%であった。また,その分布別検討では,岡山県,兵庫県,大阪府,広島県,山口県,愛媛県からの入院患者が多い傾向が見られた。
Abstract Alternative The kind of respiratory disease, age, and areas where patients came from were analyzed in 511 patients with chronic obstructive pulmonary disease (COPD) admitted at Misasa Medical Branch for last 5 years from 1993 to 1997. 1.For the last 5 years 594 patients with respiratory diseases were admitted at Misasa Medical Branch. Of these patients 511 (86.0%) were those with COPD. Of the 511, 416 (81.4%) were patients with asthma, 20 with chronic bronchitis, 27 with obstructive bronchiolitis, and 48 with pulmonary emphysema. 2.The number of patients with pulmonary emphysema showed a tendency to increase in recent years. 3.Regarding the distribution of age of these patients, the number of patients over the age of 60 was larger than the number of patients under the age of 59:patients between the ages of 60 and 69 were more frequently observed in those coming from distant area (outside Tottori prefecture), and those over the age of 70 in those coming from Tottori prefecture. 4. The number of patients from distant areas (outside Tottori prefecture) was considerably larger (48.4% in 1997) compared to the number of patients from Tottori prefecture. The number of patients from Okayama, Hyogo, Osaka, Hiroshima, Yamaguchi and Ehime was predominantly larger than the number of patients from other distant areas.
