| 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 | 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 | 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 | 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 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 | 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 | 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 | 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 | 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 | 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 | 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 | 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 | 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 | The purpose of this study was to examine the potential role of magnetic resonance imaging (MRI) in the evaluation of low back pain (LBP). The study group, 19 patients with low back pain (2 subjects aged 32-39 years and 17 aged 59-78), underwent MRI of the lumbar spine. Disc degeneration at L4/5 was the most common finding (68.4%). Overall in present study, all patients with LBP had abnormalities around the lumbar spine (evidence of disc degeneration, deformity of lumbar spine, disc bulging or protrusion, facet hypertrophy, nerve root compression and so on). |

| Abstract | In previous studies, we have demonstrated that chronic administration of systemic glucocorticoids decreases cortical bone mineral density (BMD), cortical bone volume, bone strength, and induces development of pathologic fractures in asthmatic patients. We have also demonstrated that glucocorticoid administration appears to be responsible for the process of cortical bone porosity at both endosteal and intracortical sites in postmenopausal asthmatic patients. There is a difference of gonadal hormones between male and female. To investigate the influence of hormonal difference on glucocorticoid-induced cortical bone porosity, we studied cortical bone volume and BMD in both male and female patients with asthma in this report. A total of 99 asthmatic patients (male 26 cases, female 73 cases) were enrolled in the study. Peripheral quantitative computed tomography (pQCT) was used to measure cortical BMD and relative cortical volume. The cortical volume-density relationship appeared to remain constant regardless of the level of systemic glucocorticoid administration, age or sex, suggesting cortical bone porosity causes similar and simultaneous decreases in cortical bone volume and density. In conclusion, glucocorticoid administration appears to be responsible for the process of cortical bone porosity at both endosteal and intracortical sites despite the gonadal hormonal differences. |

| Abstract | Dietary supplementation with perilla seed oil, a vegetable oil rich in α -lin- olenic acid, inhibits the generation of leukotrienes(LTs) by leucocytes in patients with bronchial asthma. We examined the factors that affect the suppression of LT generation by leucocytes with perilla seed oil-rich supplementation in patients with asthma, by comparing the clinical features of patients with asthma, whose generation of leukotriene (LT) C4 was suppressed by dietary supplementation with perilla seed oil (n-3 fatty acids) (group A), with those of patients who showed no suppression of LTC4 generation (group B). Group A showed a significant increase in the generation of LTB4 and L TC4 by leucocytes after corn oil-rich supplementation (n-6 fatty acids), and a significant decrease in the generation of LTB4 and LTC4 after perilla seed oil-rich supplementation (n-3 fatty acid). However, this was not observed in group B. The level of serum IgE and peak expiratory flow (PEF) in group A were significantly higher than in group B. Furthermore, the serum levels of LDL-cholesterol, β-lipoprotein and phospholipid were significantly lower in group A than in group B. These results suggest that the clinical features differ between these two asthmatic populations with respect to suppression of LTB4 and LTC4 generation by n-3 fatty acids in perilla seed oil-rich supplementation. |

| Abstract | In 1993, Menshikov and Zuev introduced ρ−percolation model, in which a path of a graph is ρ−passable in a bond percolation configuration if the concentration of open bonds on it is at least ρ, and concerning this model, they gave four open problems. In this paper, we answer three problems out of them : the first one is whether the ρ−percolation critical probability is equal to the critical probability corresponding to finite/infinite expectation of the number of ρ−connectable vertices from a fixed vertex, the second is whether the 1-p ercolation critical probability is equal to the Bernoulli bond percolation critical probability, and finally the third is whether the probability of the existence of ρ−passable path of length exceeding n starting from a fixed vertex always decays exponentially in the subcritical phase. |

| 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 |
