Abstract The purpose of this study is to establish a new, non - invasive diagnostic technique for peripheral circulation in patients with diabetes mellitus in the early stage of arteriosclerosis obliterans (ASO) as one of the complications of diabetes mellitus. We observed peripheral circulation quantitatively by thermography and Laser- Doppler blood flowmetry. The body surface peripheral circulation in 27 patients with diabetes mellitus, including 14 males and 13 females with a mean age of 67.4 years (range from 51-82 years), and with a mean hemoglobin A1C (HbA1C) 019.5% (range from 6.8%-13.0%), and who were suffering coldness, numbness or pain in their feet, was examined using thermography and Laser- Doppler blood flowmetry. 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 after hot-loading] Xl00 (%). Results of recovery ratios for 27 cases were 0% - 93.5%, and the average was 34.0%. At the same time, the blood flow after cold -loading was 0.91 - 5. 36ml/min/lOOg tissue and the average was 2.04ml/min/l00g tissue. We found that the recovery ratio and the blood flow were correlated (r=O. 634, p<O. 0001). The recovery ratio for males was 28.4% and that of females was 39.9%, and there was a tendency for the recovery ratio of females to be higher than males, however, this was not statistically significant. There was a correlation between the recovery ratio and age (r=O.187, p < 0.0001), although, the correlation was low. There was also a slight correlation between the recovery ratio and HbA1C (r=0.041, p<O.OOl). On the other hand, the blood flow of males was 2. 03ml/min/lOOg tissue and that of females was 2.05. There was a tendency for the recovery ratio of females to be higher than males. however. the correlation was not significant. There was a correlation between blood flow and age (r=O. 110, p<0 . 0001) , however, the correlation was low. There was also a slight negative correlation between blood flow and HbA1C (r=-0.179, p<O.OOOl). The ratio of the blood flow after cold -loading at 20t divided by the blood flow after hot -loading at 36 C was 38.1 %-122%, and the average was 80.6%. There was correlation between this ratio and the recovery ratio (r=0.502, p<O.OOOl). The case of the peripheral blood flow recovered immediately to the amount of the hot-loading or access amount of hot-loading after cold-loading, and had a high recovery ratio of thermography. This might mean that the cooled body surface was warmed by overcirculation of blood flow to keep body temperature at 30C in the mean of homeostasis. We showed that thermography and Laser- Doppler blood flowmetry were useful for non - invasive study to separate patients with poor peripheral circulation. We recommend that these methods for evaluation of further treatment, such as with Prostaglandin E1, on peripheral circulation in patients with diabetes mellitus and ASO.
Abstract Alternative 糖尿病患者における閉塞性動脈硬化症の合併を早期に診断,予知,予防する目的で末梢循環障害の程度を非侵襲的にかつ客観的に測定することを試みた。非侵襲的測定方法としてサーモグラフィーとレ-ザードップラー血流計を同時に用い,得られた結果を数量化した。症例は,下肢に冷え症,しびれ感,下肢痛を有した51歳から82歳までの 27症例(平均年齢67.4歳)であった。性別は,男性14例,女性13例,HbA1Cは6.8%-13.0%,辛均9.5%であった。サーモグラフィー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-【20℃冷水負荷後の27℃以上の体表面温度のサーモグラフィーの画素(pixel)の総数】÷【36℃の温水負荷後の27℃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-モグラフィーにより測定された回復率は0%-93.5%の範囲にあった。平均は34.0%であった。レーザードップラー血流計により20℃冷水負荷後に測定された血流量は0.91-5.36ml/min/100g tissueの範囲にあった。平均は2.04mi/min/100g tissueであった。得られたサーモグラフィーの回復率とレ-ザードップラ-血流計の血流量との間には正の相関関係を認めた(p<0.0001,r=0.634)0 36℃の温水負荷後に測定された血流量とサーモグラフィーの回復率との間には20℃冷水負 荷後同様に相関関係(p-0.0002,r=0.483)を認めたが,相関係数は20℃冷水負荷後に比較して低値であった。性別と回復率との間には男性28%,女性40%で女性の方が回復率が高い傾向にあったが,2群間に有意差を認めなっかた。年齢と回復率の間には正の相関関係(p<0.0001,r=0.187)を認めたが相関係数は低値であった。HbA1Cと回復率との間には正の相関関係(p<0.001,r=0.041)を認めたが相関係数は低値であった。一方,性別と血流量との間には男性2.03,女性2.05ml/min/100g tissueで女性の方が血流量が多い傾向にあったが,2群間に有意差を認めなかった。年齢と血流量との間には正の相関関係(p<0.0001,r=0.110)を認めたが相関係数は低値であった。HbA1Cと血涜量との間には負の相関関係(p<0.0001,r=-0.179)を認めたが相関係数は低値であった。36℃温水負荷時の血流量を100%とした時の20℃冷水負荷時の血流量の割合を求めたところ38.1%~122%の範囲にあった。 平均は80.6%であった。冷水負荷後の血流量の温水負荷時との比と回復率との間には正の相関関係を認めた(p<0.0001,r=0.502)。このことは,末梢血流量が冷水負荷後,速やかに冷水負荷前値に回復するか,あるいはさらに前値よりも上回って増加する症例においては末梢皮膚温度の回復率が高いことが示された。 糖尿病患者における末梢循環障害の程度をサーモグラフィーとレーザ-ドップラー血流計を同時に用い非侵襲的にかつ客観的に測定することが可能であった。今後,両者の併用は糖尿病患者における閉塞性動脈硬化症の合併の早期診断,予知,予防に役立つことのみならず,末梢循環障害の程度に応じた治療とその効果について定量的な評価に有用な方法と考えられた。

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。

Abstract Clinical effects of spa therapy were examined in 150 patients with asthma in relation tobronchial hyperresponsiveness and patient age. 1. The efficacy rate of spa therapy was larger as the patient age was higher: the rate was 73.3% in patients under age 49, 81.8% in those between the ages of 50 and 59, 86.4% in those between the ages of 60 and 69, and 90.6% in those over age 70. The mean of efficacy rates was 83.3% in all subjects. 2. The bronchial hyperresponsiveness (BH) was lower as patient age was higher: the BH in patients between the ages of 60 and 69 and in those over age 70 was significantly lower compared to the BH in those under age 49 (p < O.OOl). 3. Clinical effects of spa therapy tended to be lower in patients with increased bronchial hyperresponsiveness. The bronchial hyperresponsiveness showed a tendency to decrease after spa therapy in whom the therapy was effective, however, the BH did not change in patients with slight or no efficacy during spa therapy.

Abstract 1993年1月より1999年12月までの7年間に当院へ入院した呼吸器疾患999例のうち閉塞性換気障害を示す829例(気管支慌息BA+COPD)を対象に,年齢,地域分布などの経年変化について検討を加えた。 1.最近7年間に当院へ入院した閉塞性呼吸器疾患患者829例のうち, 気管支喘息は636例(76.7% )であった。閉塞性呼吸器疾患のなかで気管支喘息の占める割合の経年変化では,1996年度が最も高く(84.5% )その後徐々に低下する傾向か見られ1999年度では65.5% であった。一方′肺気腫は近年増加の傾向を示し,19993年度では5.6% であったが.1999年度では25.6% であった。  2.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,この7年間の鳥取県外(遠隔地)からの入院患者は829例中433例(52.2% )であった。また,岡山,大阪,兵庫,広島,山口,愛媛,東京,神奈川などからの入院症例か多い傾向が見られた。  3.年齢別検討では,いずれの地域においても,高齢者の入院症例が多く,鳥取県内,県外を問わず,70才以上の症例の頻度が明らかに高い傾向か見られた.そして,50才以上の症例の全症例に対する頻度は,鳥取県内では80.9% ,県外では96.7% であり,県内ではその多くが,また県外ではそのほとんどが50才以上の症例であった。
Abstract Alternative The patients with asthma or COPD who were admitted at our hospital for last 7 years (1993-1999) were examined in relation to patient age and areas where patients came. 1. Of 829 patients with obstructive ventilatory dysfunction, 636 patients (76.7% ) had asthma. The frequency of asthma in all patients with obstructive ventilatory dysfunction was the highest (84.5% ) in 1993 and showed a tendency to decrease to 65.5% in 1999. In contrast, the frequency ofpulmonary emphysema tended to increase from 5.6% in 1993 to 25.6% in 1999. 2. The number of patients with asthma or COPD from distant areas (outside Tottori prefecture) was larger (433 patients; 52.2% ) than the number of those inside Tottori prefecture (396 patients) for 7 years. The number of patients from Okayama, Osaka, Hyogo, Hiroshima, Yamaguchi, Ehime, Tokyo, and Kanagawa was. larger than the number from other distant areas. 3 . Regarding the distribution of age of these patients, the number of patients over the age of 50 in all subjects was larger in patients from distant areas (96.7% ) than in those inside Tottori prefecture (80.9% )

Abstract The generation. of leukotrienes 84 (LT84) and C4 (LTC4) by leucocytes stimulated with Ca ionophore A23187 was examined in 71 patients with asthma (42 with atopic and 29 with nonatopic asthma) and 23 healthy controls. Of these patients,22 had SDIA (steroid-dependent intractable asthma). 1. The generation of LT84 and LTC4 by leucocytes was significantly more enhanced in patients with atopic, non-SOIA asthma than in healthy subjects, but not in patients with nonatopic asthma. The generation of LT84 and LTC4 in atopic asthma was significantly more decreased in patients with SOIA than in those with non-SOIA. 2. The LTC4 generation was significantly larger in attack stage than in attack-free stage of patients with atopic and nonatopic asthma when they had not SOIA. However, no significant difference was found in LT84 generation between attack and nonattack stages in these patients. 3. In patients with SOIA, no significant differences were observed in the generation of LT84 and LTC4 between attack and nonattack stages. The results suggest that IgE-mediated allergy and asthma attacks enhance and glucocorticoids inhibit the generation of LT84 and LTC4 by leucocytes.
Abstract Alternative 気管支喘息71例および健康人23名を対象に、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)の産生能について検討を加えた。なお、71例中ステロイド依存性重症難治性喘息(SDIA)は22例であった。1.アトピー性、16非SDIA症例におけるLTB4、LTC4産生は、健康人と比べ有意に高い値を示したが、非アトピー性喘息では健康人との間に有意の差は見られなかった。また、アトピー性喘息では、SDIA症例において非SDIA症例に比べ、LTB4、LTC4産生が有意に抑制されていた。2.非SDIA症例では、アトピー性、非アトピー性を問わず、LTC4産生は、非発作時に比べ発作時に有意に亢進した状態であった。しかし、LTB4産生には、非発作時、発作時との間に有意の差は見られなかった。3.SDIA症例では、LTB4、LTC4産生と発作との有意の関連は見られなかった。以上の結果より、IgE にmediateされるアレルギー反応や喘息発作はLTB4、LTC4産生に促進的に、また副腎皮質ホルモンは抑制的に作用することが示唆された。

Abstract Alternative The parients with asthma who were admitted at our hospital for last 5 years (1994-1998) were examined in relation to age and areas where patients came. 1. Of 664 patients with respiratory disease admitted for last 5 years, 437 patients (65.8% ) had asthma. The frequency of asthma in all patients with respiratory disease was the highest (74.4% ) in 1995, and decreased in 1997 and 1998 (60.7% ). 2. The number of patients with asthma from distant areas (outside Tottori prefecture) was constantly larger than the number of those inside Tottori prefecture in each year. The number of patients from Okayama, Osaka, Hyogo, Hiroshima, Yamaguchi, and Ehime was larger than the number from other distant areas. 3. Regarding the distribution of age of these patients, the number of patients over the age of 60 was more frequently observed, regardless of the area where patients came. Larger number of patients over the age of 70 (35.1% ) was found in those inside Tottori prefecture, while the number of patients between the ages of 60 and 69 (37.7% ) was larger in those from distant areas.

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 The body surface peripheral circulation in 12 cases, including 9 patients with diabetes mellitus who were suffering coldness, numbness or pain in their feet, and 3 healthy volunteers was examined using Laser-Doppler blood flowmetry. At the same time, the body surface temperature was estimated by 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(%). The recovery ratio and the blood flow were correlated, r=0.68, p<O.01. The peripheral circulation of 16 patients with diabetes mellitus was observed at three different conditions including, l)placed at room temperature at 20℃for 15 min, 2) submerged and warmed for 5 min in a hot bath at 36℃(i.e. hot loading), and 3) submerged and cooled for 5 min in a water bath at 20℃ (i.e. cold loading). Three different baseline temperatures, 26℃, 27℃ and 28 ℃, were used in processing the thermographic results into pictures. The highest correlation (r=0.59, p=0.0002) was obtained under the condition of cold loading using a baseline temperature limitation of27℃.The difference ratio (%) of blood flow was calculated as the blood flow at cold loading divided by the blood flow at hot loading in these 16 patients. The difference ratio of the blood flow and the recovery ratio of thermography were correlated, r=0.46, p<O.OOO1. We found a strong correlation between the results of Laser-Doppler blood flowmetry and one of thermographic methods used to monitor peripheral circulation in patients with diabetes mellitus. Cold loading using a baseline temperature limitation of 27℃ were recommended for further examinations. Patients with low blood flow as well as with large differences in their peripheral circulation between cold loading and hot loading had severe coldness in their body surface temperature. We showed the usefulness of the results of thermography, when quantified by picture processing using computer software, in relation with the results of Laser-Doppler blood flowmetry.
Abstract Alternative 末梢神経障害を有する糖尿病患者の末梢循環障害の程度を数量的に検討する目的で、下肢に冷感ならびにしびれ感または疼痛を訴える糖尿病患者9症例と健常ボランティア3例の計12例(平均年齢59歳)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。更に,サーモグラフィーで得られた結果と末梢皮膚血流量をレーザードプラー血流計を用いて測定して得られた結果と比較した。サーモグラフィーによる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27℃以 上の体表面温度のサーモグラフィーのPixelの総数]÷ [冷水負荷前の特定温度27℃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。レーザードプラ-血流計を用いて測定して得られた末梢血流量は左右それぞれ5カ所,計10カ所の測定値の平均で表示した。その結果,末梢皮膚温度の回復率と末梢皮膚の血流量との問には正の相関関係(r=0.68,p<0.01)が認められた。次に,末梢皮膚血流量について,室温20℃安静15分後,温水36℃浸水負荷10分後,冷水20℃浸水負荷30分後の異なる3条件について、またサーモグラフィーで得られた結果を,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との関連について検討を行なった。対象は,下肢に冷感ならびにしびれ感または疼痛を訴える糖尿病患者16症例(平均年齢69歳,平均HbAIC9.6%)について測定した。その結果,末梢皮膚 血流量は冷水20℃浸水負荷30分後に測定して得られた結果と,回復率は特定温度27℃で画像処理して得られた結果とが最も相関が高い(r=0.59,p=0.0002)ことが示された。`次に,相関が高い条件は,室温20℃安静15分後に血流量を測定した場合(r=0.483,p=0.0002)であった。そして温 水36℃浸水負荷10分後に測定して得られた結果とが最も相関関係が低い結果となった。更に,冷水20℃浸水負荷30分後に測定して得られた結果を温水36℃浸水負荷10分後に測定して得られた結果で割った比を%で表示したところ回復率とこの比との間には正の相関関係(r=0.46,p<0.0001)が認められた。このことから,温水36℃負荷時と,冷水20℃負荷時との差が大きい患者 において末梢皮膚温度の低下が著しいことが示された。これまで悲観血的に測定されてきたサーモグラフィーによる末梢循環の数量的評価の試みは,レーザー血流計による結果と組み合わせることで,両者の間に正の相関関係が示されたことにより,今後,数量化された客観的評価を可能にした。

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 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 Alternative 肺気腫患者17名を対象として,カルシウムイオノフォアA23187による末梢血白血球からのロイコトリエンB4(LTB4), ロイコトリエンC4(LTC4)の産生能の検討を行った。対象は高分解能CTによる平均CT値によってA(<940HU), B(-940≦,<-930HU),C(-930HU≦)の3群に分類した。1.% FVC,FEV1.0%,% DLcoが低下するにつれて平均CT値が低下する傾向が見られた。% FVC値はC群に比較して,A群において有意に低値を示した(p<0.05)。2.LTB4とLTC4の産生能は健常人に比較して,肺気腫患者において有意に高値を示した(LTB4;p<0.05,LTC4;p<0.05)。3.肺気腫患者におけるLTB4とLTC4の産生能は平均CT値が上昇するにつれて(軽症症例ほど)高値を示した。またLTC4産生能はC群(早期肺気腫症例)においてA群(進行肺気腫症例)に比して有意に高値を示した。以上より肺気腫におけるLTB4,LTC4産生能は進行例に比較すると,軽・中等症例において高値であることが示唆された。

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 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 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.

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。
