Abstract | Dietary sources of a -linolenic acid, such as perilla seed oil, may have the capacity to inhibit the generation of leukotrienes (LTs) by leucocytes in patients with asthma, as has been reported with the consumption of other long - chain n- 3 fatty a-cids. The factors affecting the suppression of leukotriene (LT) C4 generation by leucocytes were examined by comparing the clinical features of patients with asthma who had been given dietary perilla seed oil (n - 3 fatty acids). Group A consisted of patients in whom the leucocyte generation of dietary perilla seed oil LTC4 was suppressed by this procedure. Group B consisted of those in whom LTC4 generation was not suppressed. LTC4 generation by leucocytes significantly decreased in group A for two (P<0.05) and four weeks (P<O. OS), conversely, significantly increased in group B for four weeks (p<O. OS). The two study groups differed significantly in LTC4 generation by leucocytes after four weeks of dietary supplementation (P<0.05). Ventilatory parameters such as peak expiratory flow (PEF) , forced vital capacity (FVC) and forced expiratory volume in one second (FEV(1.O)) increased significantly after four weeks of dietary supplementation in group A (P<0.05). Values of PEF, FVC, FEV(1.O) and V(25) between groups A and B significantly differed prior to dietary supplementation. Serum levels of total cholesterol, LDL- cholesterol and phospholipid were significantly decreased by dietary supplementation in group A after four weeks. Serum levels of total-choles terol, triglyceride, HDL-Cholesterol, LDL-Cholesterol and phospholipid values between the two study groups differed significantly prior to dietary supplementation. Serum levels of triglyceride and LDL- cholesterol differed significantly between the two study groups after four weeks of dietary supplementation. The effects of dietary supplementation with perilla seed oil to patients with asthma by suppressing the generation of LTC4 is associated with clinical features such as respiratory function and lipometabolism. |
Abstract Alternative | エゴマ油のようなα-リノレン酸食が他のn-3系不飽和脂肪酸食において報告されてきた様に喘息患者の白血球ロイコトリエン(LTs)産生能を抑制すると考えられる。そこでエゴマ油(n-3系脂肪酸)を摂取した気管支喘息患者の臨床所見を比較することによって白血球ロイコトリエン(LT)C4の抑制に影響する因子を検討した。A群はエゴマ油摂取により白血球LTC4の産生能が抑制された群であり、B群は白血球LTC4の産生能が抑制されなかった群である。A群では食事摂取2週後(P<0.05),4週後(P<0.05)に白血球LTC4産生能が低下した。逆にB群では摂取4週後有意に増加した(P<0.05)0 2群間で食事摂取4遡後に白血球LTC4産生能に有意差がみられた(P<0.05)。ピークフロー値(PEF)、努力性肺活量(FVC)、1秒量(FEV(1))といった呼吸機能はA群において食事摂取4週後に有意に上昇した(P<0.05)。食事摂取前のPEF、FVC、FEV(1)、V(25)はA群,B群の2群間で有意差がみられた。A群において血清総コレステロール、低比重リポ蛋白(LDL)コレステロール、リン脂質は食事摂取4週後に有意に低下した。食事摂取前の血清総コレステロール、中性脂肪、高比重リポ蛋白コレステロール、LDLコレステロール、リン脂質において2群間に有意差がみられた。血清中性脂肪、LDLコレステロールは食事摂取4週後2群間に有意差がみられた。気管支喘息患者のある群へのエゴマ油食はLTC4産生能を抑制し、それには呼吸機能や脂質代謝といった臨床因子が関連していると考えられた。 |

Abstract | (目的) MRlは腰痛をきたす疾患の診断に必須な検査法である。腰痛と腰椎MRl所見との関係を明らかにすることを目的として検討した。(対象と方法)腰痛を訴えた30例を対象とし、腰椎MRl所見の頻度を調査した。全例に温泉療法を施行した。 (結果)全症例において腰椎MRl上異常所見を認めた。少なくとも1つ以上の椎間板の変性病変をもつ症例は30例中27例(90% )で、椎間板変性はL4/5levelで最も多く認められた(30例中18例)。椎間板ヘルニア を示す症例は30例中10例(33.3% )であった。神経根圧迫を持つ症例は30例中8例(26.7% )であった。腰椎圧迫骨折を持つ症例は30例中6例(20% )であった。温泉療法により腰痛が改善した症例は30例中17例(56.7% )であった。 (結論)腰痛症患者は腰椎MR止異常所見を有した。温泉療法により腰痛の改善を認めたので、MRL上で認めた形態学的異常は必ずしも機能的異常や症状に直結しないと思われた。 |
Abstract Alternative | (Purpose) Magnetic resonance imaging (MRI) is essential to diagnosis of diseases which happen low back pain. The purpose of this study was to investigate the relationship between low back pain and the characteristics on MRI scans of the lumbar spine. (Materials and Methods) We performed MRI examinations of lumbar spine in 30 patients with low back pain and examined the prevalence of abnormal findings on MRI scans of the lumbar spine in 30 patients with low back pain. (Results) Overall in present study, all patients with low back pain had abnormalities around the lumbar spines on MRI. Disc degeneration was present in one or more lumbar levels in 27 (90% ) of all the subjects. The disc degeneration was most commonly observed at U/LS, where 18 (60% ) of all the subjects displayed evidence of disc degeneration. Disc herniation was found in 10 (33.3% ) of all the subjects. Nerve root compression at one level or more was observed in 8 (26.7% ) of the subjects. Compression fracture at one level or more was observed in 6 (20% ) of all the subjects. Spa therapy improved low back pain in 17 (56. 7% ) of the subjects. (Conclusion) All patients with low back pain had abnormalities around the lumbar spines on MRI. Because spa therapy improved low back pain, morphological abnormalities on MRI scans don't always connect with functional abnormalities and symptoms. |

Abstract | A 71-year-old Japanese man with adenocarcinoma of the lung developed interstitial pneumonia after treatment with paclitaxel. The patient had acute chills and fever on the fourth day after the second exposure to paclitaxel, rapidly got worse despite empiric therapies, and developed prolonged respiratory failure requiring mechanical ventilation. Four months later, he died of respiratory failure due to progression of both interstitial pneumonia and lung cancer. This is the first case developing fatal paclitaxel-induced pulmonary toxicity to date. Interstitial pneumonia should be considered one of the possible life-threatening complications during treatment with paclitaxel. |

Abstract | <p>To evaluate recent improvements in lung cancer screening, we compared the results of recently conducted lung cancer screening with those of a previous screening. This study compared the survival of lung cancer patients detected by lung cancer screening conducted between 1976 and 1984 (early period) with that conducted between 1989 and 1997 (late period). Two hundred seventy-six patients with lung cancer were detected in the early period and 541 patients with lung cancer were detected in the late period. The median survival time (late : 49.8 vs. early : 27.8 months) and the 5-year survival rate (late : 47.8 vs. early : 34.8%) of the patients with lung cancer detected in the late period were significantly better than those in the early period (p = 0.0054). Among patients undergoing resection, the proportion of pathological stage I patients in the late period was significantly higher than that in the early period (late : 60.8 vs. early : 54.9%, p = 0.005). Multivariate analysis showed that the screening time period was a significant prognostic factor (hazard ratio = 0.685, 95% confidence interval : 0.563-0.832, p = 0.0002). These results were consistent with the findings of case-control studies of lung cancer screening programs in the late period recently conducted in Japan, which also showed a greater efficacy for screening than for previous case-control studies in the early period.</p> |

Abstract | <p>A pilot study was conducted to assess the efficacy and feasibility of daily low-dose cisplatin with concurrent thoracic irradiation for clinically unresectable non-small-cell lung cancer (NSCLC). Patients with inoperable NSCLC who had poor risk factors such as advanced age, poor performance status, poor lung function, or concomitant active malignancy were entered into the study. Low-dose cisplatin (6 mg/m2) was administered daily before concurrent thoracic irradiation (2 Gy/day; total dose of 60 Gy) was given. Twenty-five patients were registered. The majority of the patients had either stage IIIA (24.0%) or stage IIIB (60.0%) disease. Fifteen patients (60.0%) completed the planned treatment. Both chemotherapy and radiotherapy were stopped in 3 patients (12.0%) due to poor response, and 7 patients (28.0%) partly received radiotherapy alone as a result of their toxicity response. The proportion of total administered dose to planned dose was 90.9% for chemotherapy and 99.3% for radiotherapy, which were comparable to those in previous studies for LA-NSCLC patients without poor risk factors. Grade 3 leukopenia and neutropenia developed in 14 patients (56.0%) and 10 patients (40.0%), respectively, but grade 4 toxicity was not encountered. Grade 3 pneumonitis and esophagitis were observed in 4 patients (16.0%) and 2 patients (8.0%), respectively. The overall response rate was 60.0%. The median survival time was 22 months, and the 2-year survival rate was 50.3%. Daily low-dose cisplatin and concurrent thoracic irradiation were well tolerated even by poor-risk patients with NSCLC, and showed a therapeutic efficacy similar to that for good-risk patients.</p> |

Abstract | <p>We previously reported that anthracyclines, which could generate reactive oxygen species (ROS), could induce the urokinase-type plasminogen activator (uPA) gene expression in human RC-K8 malignant lymphoma cells and in H69 small cell lung cancer (SCLC) cells. In screening other uPA-inducible anti-cancer agents, we found that camptothecin (CPT) and its derivative, SN38, could induce uPA in RC-K8 and H69 cells. CPT and SN38, which are also used for the treatment of lymphoma and SCLC, significantly increased the uPA accumulation in the conditioned media of both cells in a dose-dependent manner. The maximum induction of uPA mRNA levels was observed 24 h after stimulation. Pretreatment with pyrrolidine dithiocarbamate (PDTC), an anti-oxidant, inhibited the CPT-induced uPA mRNA expression. Thus, CPT induces uPA through gene expression, and, therefore, CPT may influence the tumor-cell biology by up-regulating the uPA/plasmin system.</p> |

Abstract | <p>When the development of chemotherapeutic agents reaches the clinical trial stage, it is necessary to perform drug sensitivity tests quickly in order to select the most promising agents for the treatment of cancer. In order to assess the possibility of using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay as a substitute for the human tumor clonogenic assay (HTCA), we evaluated the correlation between the results obtained by these 2 assays in 5 human lung cancer cell lines. The correlation coefficient between the results of the HTCA and the MTT assay was 0.673, indicating a relatively good correlation. The correlation was most prominent in platinum analogues (r = 0.939) and good in anthracyclines/anthracenedione (r = 0.611). However, no significant correlation was observed in vinca alkaloids, etoposide, irinotecan, SN-38 (an active metabolite of irinotecan), and rhizoxin. The results of the MTT assay showed a high degree of correlation with those of the HTCA in predicting the sensitivity of cancer cell lines to platinum analogues, and anthracyclines/anthracenedione. These results suggest that the MTT assay may be more convenient and quickly performed than the HTCA and can replace HTCA in evaluating the effects of anticancer agents, especially the platinum analogues and anthracyclines/anthracenedione.</p> |

Abstract | <p>A 23-year old woman with acute biphenotypic leukemia (ABL) complained of chest pain with cough, high fever and hemoptysis during induction chemotherapy, although she had been treated with anti-biotics and micafungin. We made a clinical diagnosis of invasive pulmonary aspergillosis (IPA) based on a consolidation in the right upper lung field on a chest radiograph as well as a high level of serum beta-D-glucan (with no evidence of tuberculosis and candidiasis). We changed her treatment from micafungin to voriconazole. Later, we discovered an air-crescent sign by CT scan that supported the diagnosis of IPA. Following voriconazole treatment, clinical symptoms ceased and abnormal chest shadows improved gradually and concurrently with a recovery of neutrophils. IPA must be considered in immunocompromised patients with pulmonary infiltrates who do not respond to broad-spectrum antibiotics. Serological tests and CT findings can aid in early diagnosis of IPA, which, along with treatment for IPA, will improve clinical outcomes.</p> |
