Abstract
Combination therapy with ipilimumab and nivolumab is indicated for many types of cancers; however, several patients experience immune-related adverse events (irAEs). We herein report a case of cytokine release syndrome (CRS) in a 63-year-old woman with stage IV left clear cell renal cell carcinoma. Our patient developed CRS while taking prednisolone, 43 days after the start of ipilimumab and nivolumab administration. The patient was treated with steroid pulse therapy, which improved the symptoms of shock and respiratory failure. Increased vascular permeability and relative adrenal insufficiency are considered to be the main pathogeneses. The early administration of high-dose steroids is crucial as a replacement for corticosteroids.

Abstract
Eosinophilic granulomatosis with polyangiitis (EGPA) refers to systemic vasculitis in patients with bronchial asthma and eosinophilic rhinosinusitis. Dupilumab has been approved for the treatment of asthma, eosinophilic rhinosinusitis, and atopic dermatitis. A man in his 50s with a history of asthma and eosinophilic rhinosinusitis with nasal polyposis developed high fever and dyspnea while undergoing dupilumab treatment. Laboratory examinations identified hypereosinophilia. Chest radiography and computed tomography revealed right-sided tracheal dislocation, extensive consolidation, and ground-glass opacities with traction bronchiectasis. Evidence of interstitial pneumonia, eosinophilia, and increased eosinophil counts in the bronchoalveolar lavage fluid was observed. We diagnosed the patient with EGPA and administered corticosteroids, which improved his symptoms and radiographic signs. Although the relationship between EGPA and dupilumab treatment is unclear, EGPA may have been exacerbated by dupilumab in this case. Therefore, when administering dupilumab to patients with partial symptoms of EGPA, care should be taken to monitor for adverse symptom development and exacerbation.

Abstract
Cases of proto-oncogene B-Raf (BRAF) V600E mutation are rare, accounting for 1%-4% of non-small cell lung cancers (NSCLCs), and its clinical features remain unclear. Here, we report a case of BRAF mutation-positive lung adenocarcinoma with an atypical clinical course and long-term survival. The patient was a 63-year-old female nonsmoker who was diagnosed with stage IA adenocarcinoma after surgical resection. Five years after the surgery, cancer recurred and was treated with various cytotoxic anticancer agents. During the course of treatment, the patient was found to be BRAF V600E mutation-positive and was treated with molecular-targeted drugs. Although multiple brain, subcutaneous, and tonsillar metastases appeared, the progression was significantly slower, and the patient survived for 14 years and three months after the diagnosis. There have been few case reports of long-term survival in BRAF-positive lung cancer, and more cases need to be accumulated in the future to gather more information. Based on this case, we speculate that sensitivity to cytotoxic anticancer agents such as pemetrexed (PEM) and maintenance of performance status (PS), in addition to molecular-targeted agents, are important for long-term survival.

Abstract
We describe a case of coronavirus disease 2019 (COVID-19) in a patient with mixed cellularity classical Hodgkin lymphoma (cHL) undergoing brentuximab vedotin, doxorubicin, vinblastine, and dacarbazine (A+AVD) therapy. A 43-year-old man presented to our hospital with a complaint of fever, for which he was diagnosed with COVID-19 after a positive polymerase chain reaction (PCR) test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and antiviral therapy with favipiravir and ciclesonide was started subsequently. The fever persisted for the first few days of treatment, but his respiratory status was stable, and he became asymptomatic and afebrile on day 9. Although the PCR tests remained positive, he met the updated discharge criteria of the World Health Organization (WHO) on day 12. However, his fever recurred, and his condition worsened on day 16. A chest X-ray showed a new opacity. It is likely that favipiravir and ciclesonide treatment probably did not completely eliminate the virus in the patient, and therefore the infection persisted. We added remdesivir from day 21, and the improvement was remarkable. He was discharged on day 29 after two consecutive PCR test results were negative. PCR tests are not mandatory for the updated WHO discharge criteria. However, even after antiviral therapy, COVID-19 patients with hematologic malignancies may have prolonged active infection with impaired viral excretion. Depending on the background disease and comorbidities, there may be some patient populations for whom it is not appropriate to simply comply with the current discharge criteria. Therefore, more emphasis may be needed on PCR examinations.

Abstract
Programmed cell death protein 1 immune checkpoint inhibitor is an effective treatment for non-small cell lung cancer. Although hematological immune-related adverse events induced by antiprogrammed-cell-death-protein-1 immunotherapy have been reported, they are rare, and there remain many unknowns. We report the case of a 77-year-old woman with non-small cell lung cancer and pembrolizumab-induced danazol-dependent aplastic anemia. Sixteen days after she received pembrolizumab with carboplatin and pemetrexed as first-line treatments, she developed pancytopenia, including severe thrombocytopenia (1 × 109/L) with oral bleeding, epistaxis, and systemic purpura. We initially diagnosed immune-related thrombocytopenia based on an elevated level of platelet-associated immunoglobulin G (922ng/107 cells), but her thrombocytopenia was refractory to prednisolone (1mg/kg) and thrombopoietin receptor agonists. We eventually diagnosed aplastic anemia based on the findings of bone marrow hypoplasia. Treatment with cyclosporine and danazol 300mg (7.5mg/kg) was initiated. Eighteen days later, her blood cell count increased, and we reduced danazol to 100mg. Twenty-four days after the reduction of danazol, her platelet count dropped again to 14 × 109/L; subsequently, increasing danazol improved her platelet count in a few days. Although aplastic anemia was recovered, she died owing to lung cancer progression. In this case, the thrombocytopenia was noticeable initially; however, pancytopenia appeared a month later, and we diagnosed her with aplastic anemia. Platelet counts improved rapidly with the use of danazol. No effective treatment has yet been established for aplastic anemia induced by antiprogrammed-cell-death-protein-1 immunotherapy, but our case suggests that danazol is an effective therapy.

Abstract
We treated two patients with severe respiratory failure due to coronavirus disease 2019 (COVID-19). Case 1 was a 73-year-old woman, and Case 2 was a 65-year-old-man. Neither of them had a history of autoimmune disease. Chest computed tomography scans before the antiviral therapy showed bilateral multiple patchy ground-glass opacities (GGO) consistent with COVID-19 pneumonia. The GGO regressed over the course of the antiviral treatment; however, new non-segmental patchy consolidations emerged, which resembled those of interstitial lung disease (ILD), specifically collagen vascular disease-associated ILD. We tested the patients' sera for autoantibodies and discovered that both patients had high anti-SSA/Ro antibody titers. In Case 1, the patient recovered with antiviral therapy alone. However, in Case 2, the patient did not improve with antiviral therapy alone but responded well to corticosteroid therapy (methylprednisolone) and made a full recovery. The relationship between some immunological responses and COVID-19 pneumonia exacerbation has been discussed previously; our discovery of the elevation of anti-SSA/Ro antibodies suggests a contribution from autoimmunity functions of the immune system. Although it is unclear whether the elevation of anti-SSA/Ro antibodies was a cause or an outcome of aggravated COVID-19 pneumonia, we hypothesize that both patients developed aggravated the COVID-19 pneumonia due to an autoimmune response. In COVID-19 lung injury, there may be a presence of autoimmunity factors in addition to the known effects of cytokine storms. In patients with COVID-19, a high level of anti-SSA/Ro52 antibodies may be a surrogate marker of pneumonia severity and poor prognosis.

Abstract
Abstract
Background and purpose
Many reports have examined electrocardiographic (ECG) changes after subarachnoid hemorrhage from long ago; however, there are few reports on the prognosis of patients who have an ECG abnormality. Therefore, in this study, the prognoses of patients with subarachnoid hemorrhage showing abnormal ECG findings were retrospectively analyzed.
Methods
Over 30 months from January 2014 to June 2016, 199 patients (mean age, 61.1±17.0 years; 46.7% male) admitted with a subarachnoid hemorrhage (SAH) were enrolled. To assess the mechanism underlying abnormal ECG in the SAH, predictor variables, such as demographics (age, sex, and body surface area), hemodynamics (heart rate and systolic blood pressure), blood biochemical results, neurological assessments (Glasgow Coma Scale), and computed tomography (CT) severity classification (World Federation of Neurosurgical Societies classification) were recorded. The subarachnoid hemorrhage was classified into either the cerebral aneurysm rupture group (N=132) or traumatic subarachnoid hemorrhage group (N=67) and analyzed.
Results
In the cerebral aneurysm rupture group, the QT prolongation was significantly increased compared with the traumatic subarachnoid hemorrhage group (424.8±87.7 ms vs. 400.5±95.8 ms, P<0.05). There was a correlation between consciousness level (Glasgow Coma Scale) on admission and QT prolongation, and significant QT prolongation was observed in critical patients (Pearson's correlation coefficient test P=0.04). ST changes correlated with CT classification severity (WFNS classification), and the most severe group (WFNS Grade 5) showed significant ST changes. On admission, the cerebral aneurysm rupture group and 97.0% in the traumatic subarachnoid hemorrhage group.
Conclusions
Significantly prolonged QT and ST changes are noted in patients with severe aneurysmal subarachnoid hemorrhage. The cause of the ECG abnormality in subarachnoid hemorrhage patients is not yet understood. A small number of experimental animal models have shown that electrocardiogram abnormalities associated with subarachnoid hemorrhage develop in the brain stem, and an autonomic nerve abnormality may also be involved.
A D-dimer is positively correlated with both aneurysm trauma and traumatic subarachnoid hemorrhage and may be used for auxiliary diagnosis of a subarachnoid hemorrhage.

Abstract
Background It is unclear whether changes in serum tumor marker expression post-treatment are of prognostic value. We investigated the associations between changes in serum carcinoembryonic antigen (CEA) and cytokeratin 19 fragment (CYFRA 21-1) after first-line treatment and overall survival (OS) in non-small cell lung cancer (NSCLC). Methods Advanced NSCLC patients (April 2010 to December 2015) with elevated serum CEA or CYFRA 21-1 were included. The associations between tumor marker changes after treatment initiation and OS were analyzed. Results Ninety-six and 55 patients were CEA- and CYFRA 21-1-positive, respectively. The serum CEA response at 4 months and CYFRA 21-1 responses at 1 and 4 months were significantly associated with OS in the univariate analyses (P=0.025, P=0.016 and P<0.001, respectively). Moreover, in the multivariate analyses, serum CYFRA 21-1 response at 4 months was significantly associated with improved OS (P=0.038). Conclusions In NSCLC patients, serum CEA and CYFRA 21-1 responses after treatment initiation may predict longer OS.

Abstract
Background In epidermal growth factor receptor (EGFR)‐mutant non‐small cell lung cancer (NSCLC), brain metastasis is known as a poor prognosis factor. However, prognostic factors in the patients without brain metastasis remain unclear. In this study, we aimed to clarify the differences between metastatic site and prognosis in common EGFR‐mutant NSCLC patients without brain metastasis. Methods Chemotherapy‐naïve, advanced EGFR‐mutant NSCLC patients without brain metastasis diagnosed between January 2010 and March 2016 were enrolled. We evaluated prognosis according to the presence or absence of bone metastases, liver metastasis, and pleural effusion. Results A total of 50 EGFR‐mutant NSCLC patients without brain metastasis were enrolled. The median progression‐free survival and overall survival were significantly shorter in patients with pleural effusion than in those patients without (progression‐free survival 7.0 months, 95% confidence interval [CI] 3.7–13.0 vs. 13.0 months, 95% CI 9.1–21.7, hazard ratio [HR] 2.29, 95% CI 1.11–4.73, P = 0.020; overall survival 19.5 months, 95% CI 5.7–28.8 vs. 55.3 months, 95% CI 24.0–not evaluable, HR 3.00, 95% CI 1.35–6.68, P = 0.005). Pleural effusion was an independent factor of poor prognosis for progression‐free survival (HR 3.44, 95% CI 1.50–7.88, P = 0.003) and overall survival (HR 2.34, 95% CI 1.00–5.44, P = 0.049). Conclusion Pleural effusion might be a poor prognosis factor for advanced EGFR‐mutant NSCLC patients without brain metastasis treated with first‐generation EGFR‐tyrosine kinase inhibitors. Further precision medicine according to the metastatic site is required.

Abstract
Pseudoprogression was reported as one of the unconventional responses during immune checkpoint inhibitor therapy. A 70-year-old man with pulmonary pleomorphic carcinoma received nivolumab therapy. Pleural effusion and pulmonary metastasis increased, however then shrank and serum cytokeratin 19 fragment levels decreased. Serum tumor marker might help to distinguish pseudoprogression.

Abstract
A 79-year-old man with a history of tuberculosis was found to have chronic empyema in the right lung and was diagnosed with malignant diffuse large-cell lymphoma (Ann Arbor stage IIE). After completion of one course of rituximab plus cyclophosphamide, pirarubicin, vincristine, and prednisolone (R-CHOP) chemotherapy, the patient developed lung abscess and sepsis caused by Streptococcus intermedius. This condition was treated with antimicrobial agents, and chemotherapy was resumed. After the second course, the chemotherapy regimen was continued without prednisolone, and after administration of the third course, a chest wall mass was found in the right lung. An acid-fast bacillus smear test of the abscess aspirate was positive, and Mycobacterium tuberculosis was detected in a polymerase chain reaction assay, leading to a diagnosis of perithoracic tuberculosis. Chemotherapy for the lymphoma was discontinued, and treatment with four oral antitubercular agents was started. This treatment led to remission of perithoracic tuberculosis. In Japan, tuberculous scar and chronic empyema are relatively common findings, and relapse of tuberculosis should always be considered for patients with these findings during chemotherapy and immunosuppressive therapy.

Abstract
Erlotinib is a newly developed molecular-targeting or molecular-targeted drug with selective inhibitory activity for tyrosine kinase of the epidermal growth factor receptor. A adverse drug reactions including diarrhea, skin eruptions are considered mild. We report a case of recurrent adenocarcinoma of the lung in a 68-year-old woman who suffered from Henoch-Schönlein purpura induced by erlotinib. She received daily administration of erlotinib 150 mg as second-line chemotherapy. Her tumors decreased in size and pleural effusion disappeared, so we considered erlotinib effective. However after 3 months of treatment with erlotinib, the patient presented palpable purpuric lesions mostly located on her lower legs. We diagnosed Henoch-Schönlein purpura based on skin histological findings. Erlotinib was reduced but continued, with improvement of the eruptions. Henoch-Schönlein purpura is often accompanied by systemic manifestations, such as renal disease and arthritis, so more careful follow-up is warranted.

Abstract
It is known that children with cochlear implants tend to sing off-key, monotonously, and flat. There are a few reports that it is possible to improve off-key singing mainly through instruction using the falsetto voice for people with normal hearing. We examined whether their singing skills could be improved through instruction. Eight subjects (five boys and three girls aged 10.4+/-2.4 years) with cochlear implants were selected. Speech perception scores of short sentences were on average 66.5%+/-26.5%. We diagnosed their singing acuity by letting them sing a nursery song, well known to all of them, before and after the instruction. The mean fundamental frequencies of their singing approached the mean Musical Instrument Digital Interface (MIDI)-specified frequencies as references and the deviation between fundamental frequencies of their singing and reference MIDI sounds became smaller. This study shows a clear improvement in the singing ability of children with cochlear implants through a unique technological voice method, mainly focused on the falsetto voice in this experiment.

Abstract
STUDY OBJECTIVES High-concentration oxygen therapy is used to treat tissue hypoxia, but hyperoxia causes lung injury. Overproduction of nitric oxide by nitric oxide synthase (NOS) is thought to promote hyperoxic lung injury. The present study was conducted to examine the role of inducible nitric oxide synthase (iNOS) in hyperoxic lung injury in mice. MEASUREMENTS AND RESULTS Mice were exposed to >98% oxygen for 72 h, and ONO-1714 (0.05 mg/kg) (ONO) was subcutaneously administered to block iNOS. Hyperoxia significantly increased total cell count, protein concentration, and nitrites/nitrates in the bronchoalveolar lavage fluid and proinflammatory cytokines in the lung tissue. ONO significantly prevented the increases in all of these variables. ONO suppressed histologic evidence of lung injury. ONO markedly inhibited iNOS protein expression and nitrotyrosine production in lung homogenates. After exposure to hyperoxia, alveolar epithelial cells stained positively for 8-hydroxy-2'-deoxyguanosine, a proper marker of oxidative DNA damage by reactive oxygen species. ONO attenuated this finding. CONCLUSIONS NOS play important roles in the pathogenesis of hyperoxic lung injury. Selective iNOS inhibitors may be useful for the treatment of hyperoxic lung injury.

Abstract
Excessive nitric oxide (NO) generated by inducible nitric oxide synthase (iNOS) aggravates acute lung injury (ALI) by producing peroxynitrite. We previously showed by immunostaining that the expression of iNOS was suppressed by inhalation of N(G)-nitro-L-arginine methyl ester in mice with Candida-induced ALI. This study tested the hypothesis that a novel iNOS inhibitor suppresses not only iNOS expression, but also iNOS messenger RNA (mRNA) production by interrupting a positive feedback loop at the time of NO production in Candida-induced ALI. Mice were pretreated by inhalation of saline or ONO-1714, a selective iNOS inhibitor, and were given an intravenous injection of Candida albicans to induce ALI. After inhalation of 1 mM aerosolized ONO-1714, the nitrite-nitrate concentration in bronchoalveolar lavage fluid (BALF) at 24 h was significantly lower than that after inhalation of saline. Tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) levels and neutrophils in BALF were decreased by inhalation of ONO-1714. Inhalation of ONO-1714 markedly suppressed nitrotyrosine production and inhibited the expression of iNOS mRNA as well as proteins in the lung. Survival was prolonged by inhalation of ONO-1714. We conclude that pretreatment with inhaled ONO-1714 suppresses the production of peroxinitrite and decreases oxidative stress associated with peroxinitrite in Candida-induced ALI.

Abstract
BACKGROUND Exposure of animals to hyperoxia causes lung injury, characterized by diffuse alveolar damage and exudation of plasma into the alveolar space. Reactive oxygen species (ROS) play an important role in the development of hyperoxic lung injury. Mitochondrial oxidative phosphorylation is one of the major sources of ROS. N-acetylcysteine (NAC) is a precursor of glutathione (GSH), which functions as an antioxidant by reducing hydrogen peroxide to water and alcohols. NAC has been shown to diminish lung injury in a large variety of animal models. AIM We elucidated the mechanism underlying the protective effects of NAC in hyperoxia-induced lung injury. METHODS Male BALB/c mice were exposed to 98% oxygen for 72 h. The mice inhaled NAC or saline twice a day from 72 h before oxygen exposure to the end of experiment. RESULTS Inhaled NAC increased the GSH level in lung homogenate. NAC also attenuated cellular infiltrations in both bronchoalveolar lavage fluid (BALF) and lung tissue. The total protein level in BALF and the level of 8-isoprostane, a marker of lipid peroxidation, in lung homogenate were decreased by inhalation of NAC. Inhaled NAC induced the overexpression of Mn superoxide dismutase (MnSOD) mRNA and protein, but did not alter the expressions of other antioxidant enzymes, including CuZnSOD, extracellular SOD, and glutathione peroxydase 1. CONCLUSION These findings suggest that the antioxidant properties of NAC in hyperoxic lung injury involve a decrease in mitochondrial ROS in association with the induction of MnSOD, in addition to its role as a precursor of GSH.

Abstract
We report 4 cases of spinal cord metastases of lung cancer detected by MRI. Histologically, 3 of the 4 cases were small cell carcinoma and the other was adenocarcinoma. All 3 cases of small cell carcinoma had neoplastic meningitis. MRI taken in these cases showed the multiple nodules in the cauda equina, which were seeded from brain metastases. One of them had intramedullary spinal cord metastases, which appeared as enlargement of the spinal cord or nodules in the spinal cord on MRI. Leg paralysis and incontinence progressed in all cases. The other case of adenocarcinoma had epidural spinal cord compression due to spinal metastasis. In this case irradiation and corticosteroids relieved her leg and back pain. Spinal cord metastases should be considered as a differential diagnosis in patients with numbness, pain or weakness in the extremities.

Abstract
A 27-year-old woman was admitted because of right dry eye and blurred vision. She was given a diagnosis of uveitis due to sarcoidosis. Chest X-ray film showed bilateral hilar lymphadenopathy and multiple nodules in both lungs. The nodules were considered to be associated with sarcoidosis. However chest CT demonstrated that the nodules were well-defined and connected with two vessels. We diagnosed diffuse pulmonary arteriovenous malformations (AVMs) by 3D-CT. In three of sixteen AVMs, the feeding vessels were more than 3 mm wide in diameter on pulmonary arteriography, and those were embolized by platinum coils. The embolotherapy of diffuse AVMs could not ameliorate the shunt fraction sufficiently, but should reduce the possibility of the catastrophic complication of brain abscess.

Abstract
PURPOSE To evaluate the effectiveness of fluoroscopy-guided barium marking for localization of small peripheral pulmonary lesions before video-assisted thoracic surgery (VATS) resection. MATERIAL & METHODS Twenty-one patients with peripheral pulmonary lesions 15 mm or less in diameter who were scheduled to undergo VATS resection were studied. A catheter was inserted bronchoscopically into the target segment and guided to a presumed lesion. The tip of the catheter was confirmed fluoroscopically to be at the exact spot determined beforehand. A 50% (weight/volume) barium sulfate suspension was instilled into the bronchus through the catheter, and the site of barium marking was ascertained by CT scanning. RESULTS The average instilled volume of barium was 0.42+/-0.07 ml. On CT scans, barium spots were superimposed on the target lesions in 19 of the 21 patients and were only 6-7 mm from the lesions in the other 2. Barium was well preserved in all patients at the time of VATS resection. A mild cough persisted for about 1 week in one patient, but the other patients had no specific complications. CONCLUSION Fluoroscopy-guided barium marking is a safe, convenient, and reliable method for localization of small pulmonary lesions before VATS resection.

Abstract
A 28-year-old woman was hospitalized for renal transplantation. She suffered an asthma attack after transplantation. Once this attack had ended after medical treatment, she again experienced dyspnea after the 11th treatment day. A chest CT showed mucoid impaction in the left main bronchus, atelectasis in the left lower lobe, and pneumomediastinum. A huge mucoid impaction was removed with a balloon catheter under mechanical ventilation without exacerbation of the mediastinal emphysema. Mucoid impaction should be taken into account as a cause of dyspnea in severe asthma if the maximum dose of beta-stimulant is not effective.

Abstract
Thymic carcinoma is rarer than thymoma and carries a very poor prognosis. No standard treatment has yet been established. Chemotherapy and radiation therapy are usually given to patients in whom surgery is not indicated. We clinically review six patients with thymic carcinoma (three men and three women) who were admitted to our hospital from 1992 through 2002. Their ages ranged from 56 to 81 years (median 70.5). Four patients had chest pain, two were unable to swallow, and in one, who was asymptomatic, the tumor was detected by chance. Histologically, five cases were squamous cell carcinomas, and one was a lymphoepithelioma-like carcinoma. Four of the six patients had distant metastasis at diagnosis. Only one patient was able to undergo surgery, two received radiation therapy alone, and three were administered chemoradiation. The response to the chemoradiation was progression of the disease in two patients and no change in one. The response to radiation therapy was partial response in one patient and no change in one. In summary, chest pain is the most common symptom of thymic carcinoma. A symptomatic case suggests a poor prognosis resulting from the clinical behavior of thymic carcinoma, such as early distant metastasis or direct invasion of surrounding organs. Histologically, squamous cell carcinoma is the most common, and thymic carcinoma appears to be generally resistant to chemotherapy and radiotherapy.

Abstract
Echocardiography demonstrated a high echoic lesion(6 x 5 mm) in the apex of the left ventricle of a 72-year-old man(Case 1) and similar lesions(7 x 6 mm and 4 x 3 mm) in the apex of the left ventricle of a 60-year-old man(Case 2). The amplitude of cyclic variation of integrated backscattering of the high echoic lesions was measured by acoustic densitometry to be lower than that of the myocardium in Case 1, but similar to that of the myocardium in Case 2. Contrast echocardiography detected the perfusion defect of the high echoic lesion in Case 1, but not in Case 2 in the apical four-chamber view. These findings showed that the high echoic lesion indicated thrombus in Case 1, and papillary muscle in Case 2. Measurement of the amplitude of the time intensity curve with contrast echocardiography showed that the amplitude of thrombus was different from that of myocardium. This method is useful for ultrasonic tissue characterization.

Abstract
We reported a case of a 72-year-old man with chest pain. An electrocardiogram showed ST segment elevation in I, II, III, aVL, aVF and V1-6 leads. 99mTc-tetrofosmin myocardial SPECT showed defect in the anterior, septal, apical and inferior walls. Coronary angiography showed 99% stenosis of the proximal right coronary artery and total occlusion of the midsegment of the left anterior descending coronary artery. Therefore, direct PTCA was performed for each lesion to achieve reperfusion. We didnt's see reperfusion injury during PTCA of the left coronary artery. On the other side, we saw severe reperfusion injury, such as slow-flow, arrhythmia and falling blood pressure during PTCA of the right coronary artery. After four hours, 99mTc-PYP myocardial SPECT showed marked uptake in the apical and inferior walls, and mild uptake in the anterior and posterior walls. After three days, severely-reduced uptake of 99mTc-PYP in the apex was noted, and mild uptake in the mid-portion of the anterior wall and the mid-portion of the inferior wall. Though reperfusion injury was seen, three was mild myocardial uptake of 99mTc-PYP in the area of the right coronary artery. On the other side, despite no reperfusion injury, there showed marked uptake during the acute phase and defect during the subacute phase in the area of the left coronary artery. Wall motion of the left ventricle was normal in the area of the right coronary artery and akinesis was seen on the left. These findings suggest that 99mTc-tetrofosmin and 99mTc-PYP myocardial SPECT are useful for visualization of reperfusion injury during the acute phase and for estimation of function during the chronic phase, better even than electrocardiogram or coronary angiography.

Abstract
A 69-year-old woman presented with dyspnea on exertion. Echocardiography showed dilatation and diffuse hypokinesis of the left ventricle. 99mTc-tetrofosmin myocardial SPECT showed moderately reduced uptake in the anteroseptal wall and the inferior wall on the rest images, but was improved on the ATP loading images. 123I-BMIPP myocardial SPECT showed severely reduced uptake in the anterior wall and the inferior wall. These SPECT findings suggested ischemic heart disease rather than dilated cardiomyopathy. Coronary angiography showed no organic stenosis, but diffuse coronary ectasia was noted in three vessels. Intravascular ultrasound revealed remarkable coronary ectasia, with a maximal diameter of 8.2 mm. Coronary flow velocity as measured by Doppler blood flow guide wire was remarkably reduced. Coronary spasms were not provocated by ergonovine loading test. These findings suggested that microvascular thrombi and disturbance of dilatation caused myocardial ischemia in this patient. We treated the patient with ticlopidine and nicorandil. Following treatment left ventricle wall motion, 99mTc-tetrofosmin and 123I-BMIPP myocardial SPECT findings were improved.

Abstract
The subject was a 65-year-old woman with chest pain. An electrocardiogram revealed T-wave-inversion in leads III, aVF, V1-V5. 99mTc-tetrofosmin myocardial SPECT showed mildly reduced uptake in the anteroseptal wall and the apex. These findings suggested acute myocardial ischemia. Coronary angiography did not show any stenotic lesions, but diffuse coronary ectasia was noted in three vessels. Coronary flow velocity was remarkably reduced on coronary angiography. Epicardial coronary spasm was not provoked by ergonovine loading test. Left ventriculography showed diffuse hypokinesis. 123I-BMIPP myocardial SPECT showed mildly reduced uptake in the anteroseptal wall and the apex on the early images. But 4-hour delayed images showed an increase of 8% in myocardial 123I-BMIPP uptake. We treated this patient with ticlopidine and nicorandil. After drug therapy her symptoms and left ventriculography improved. 123I-BMIPP myocardial SPECT findings on the early images improved, whereas delayed images showed a decrease of 28% in myocardial 123I-BMIPP uptake after two weeks and 36% after four weeks. These dynamic changes in 123I-BMIPP findings might be a reflection of myocardial fatty acid metabolism in patients with acute myocardial ischemia. Delayed 123I-BMIPP myocardial SPECT images are useful for the assessment of fatty acid metabolism.

Abstract
A 57-year-old woman was emergently admitted to our hospital because of chest oppression. On examination, blood pressure was 174/96 mmHg, pulse rate was 90/min and coarse crackle and third heart sound were audible. On laboratory data, the levels of LDH and CPK-MB were mildly elevated. Electrocardiogram (ECG) demonstrated elevation of the ST segment in leads I, aVL and V2-V5. 99mTc-tetrofosmin myocardial SPECT (TF) showed severely reduced uptake in the apex and anterior wall. Emergent coronary angiography (CAG) did not show any stenotic lesion. Left ventriculography (LVG), however, demonstrated akinesis of the apex, anterior, and inferior walls, and basal hyperkinesis. On the second hospital day, ECG demonstrated inverted T wave in leads I, aVL and V2-V5. 123I-BMIPP myocardial SPECT (BMIPP) and 123I-MIBG myocardial SPECT (MIBG) were performed on the second and fourth hospital days, respectively. These cardiac images showed severely reduced uptake equally. TF, BMIPP, and MIBG were re-examined on the eighth, tenth, and twelfth hospital days, respectively. MIBG, BMIPP, and TF showed reduced uptake in order of severity. On the fourteenth hospital day, CAG and LVG were re-examined. Coronary vasospasm provocation test was negative using ergonovine and acetylcholine, and LVG did not demonstrated any sign of asynergy. We considered that this case was "Takotsubo" cardiomyopathy and might be caused by microvascular spasm.

Abstract
A 66-year-old-man was admitted to our hospital because of chest pain on effort in October 1999. The initial images of 123I-BMIPP myocardial SPECT (BM) showed moderately decreased tracer uptake in the apex and the delayed images revealed redistribution in the apex. Coronary angiography revealed 99% stenosis in the proximal portion of the left anterior descending artery. Since sudden onset anaphylactic shock induced by contrast media developed, so percutaneous transluminal coronary angioplasty was not performed. The patient's symptoms were improved with medical treatment. On BM in March 2000, the initial images indicated slightly reduced uptake in the apico-anteroseptal region and the delayed images revealed mildly redistribution in the same area. BM in September 2000, the initial images showed moderately reduced uptake in the apico-anteroseptal region and the delayed images revealed high washout in the same area. The patient's symptoms markedly deferiorrated in March 2001, and BM initial images revealed slightly reduced uptake in the apico-anteroseptal region and the delayed images revealed redistribution in the same area again. During the clinical course, electrocardiography and 99mTc-tetrofosmin myocardial SPECT revealed no marked changes. We consider that 123I-BMIPP myocardial SPECT is useful in estimating myocardial ischemia.

Abstract
Abstract
In the first part of this paper, impregnation was positioned in terms of consolidation in composite processing and theoretical model for impregnation behaviors was presented. Impregnation behaviors were classified using the parameters contained in the model. Calculation for some simple cases was conducted. In the second part, impregnation behaviors of two material groups were experimentally estimated by on-line measurement of tool gap displacement during compression molding for making UD composites. First material group is composed of 4 kinds of thermoplastic composite materials. The other is thermoplastic film stacking with opened and unopened reinforcing fiber tows. Microscopic observation on the cross-section of parts fabricated at various molding time and measurement of transverse bending strength of these parts were also conducted. Based on the theoretical model proposed in the first part and these experimental data, impregnation behaviors of these materials were systematically discussed. The results suggest basic technological ways for attaining good impregnation in thermoplastic composites.

Abstract
PURPOSE We studied the effect of myocardial ischemia and diabetes mellitus (DM) on the myocardial fatty acid metabolism using 123I-BMIPP myocardial scintigraphy. METHODS We performed 123I-BMIPP myocardial scintigraphy in 50 patients with myocardial ischemia and without DM (AP), in 30 patients with myocardial ischemia and DM (AP + DM), 12 patients with DM and without myocardial ischemia (DM), and in 10 normal subjects (N). Myocardial uptake rate of 123I-BMIPP was obtained using the time activity curve. Myocardial washout rate of 123I-BMIPP was calculated using the polar images of early and delayed SPECT images. RESULTS Myocardial uptake rate of 123I-BMIPP (%) were AP: 4.9 +/- 0.6, AP + DM: 5.5 +/- 0.5, DM 5.7 +/- 0.5 and N: 5.0 +/- 0.4. 123I-BMIPP myocardial uptake rate was increased in AP + DM and DM. 123I-BMIPP myocardial washout rate (%) were AP: 30.2 +/- 4.3, AP + DM: 24.5 +/- 3.9, DM: 16.1 +/- 2.8 and N: 19.4 +/- 3.2. 123I-BMIPP myocardial washout rate was increased in AP and AP + DM. 123I-BMIPP myocardial washout rate was increased particularly in patients with multi-vessels disease. 123I-BMIPP myocardial washout rate was decreased in DM. CONCLUSION The present study suggested that diabetes mellitus increased myocardial fatty acid uptake and decreased myocardial fatty acid washout, and that myocardial ischemia increased myocardial fatty acid washout.

Abstract
UNLABELLED We studied the causative mechanism of ampulla (Takotsubo) cardiomyopathy. METHODS We examined 7 patients with ampulla cardiomyopathy by means of coronary angiography, two-dimensional echocardiography and 99Tc-tetrofosmin myocardial SPECT at the time of emergency admission (acute phase), at 3 to 5 days after the attack (subacute phase) and at 1 month after the attack (chronic phase). The left ventricle was divided into 9 regions on two-dimensional echocardiograms and 99mTc-tetrofosmin myocardial SPECT images, then the degree of abnormalities in each region was scored in four grades from normal (0) to severely abnormal (3). We injected nicorandil into the coronary arteries and determined the elevation in the ST segment before and after administration. RESULTS Coronary angiography did not show stenotic lesions in any patient. The acute, subacute and chronic phase myocardial perfusion scores on 99mTc-tetrofosmin myocardial SPECT were 11.2 +/- 3.4, 2.7 +/- 2.3 and 0.4 +/- 0.5, respectively, and wall motion scores on echocardiograms were 13.0 +/- 3.6, 4.4 +/- 2.2 and 0.6 +/- 0.6, respectively, indicating improvement in all scores during the subacute phase (p < 0.01). The elevation in the ST segment (mm) on the electrocardiogram was improved from 8.3 +/- 2.7 to 4.9 +/- 1.9 after the administration of nicorandil (p < 0.05). CONCLUSION These findings indicated that coronary microvascular spasm is one causative mechanism of ampulla cardiomyopathy.

Abstract
This study was designed to evaluate the myocardial damage and metabolic disorder of the left ventricle in patients with mitral stenosis. We studied 15 patients with mitral stenosis. Their grade of chronic heart failure using New York Heart Association classification were class I: 5 patients, class II: 5, class III: 3, class IV: 2, respectively. The severely stenotic group (valve area < 1.5 cm2) included 6 patients, mildly stenotic group (1.5 cm2 < or = valve area < 2.5 cm2) included 9. A 111 MBq of 123I-BMIPP was intravenously injected at rest, SPECT images were obtained at 15 min and 3 hours after injection. A 111 MBq of 201Tl was intravenously injected at rest, and SPECT images were obtained at 15 min after injection. Washout rate (WR) of 123I-BMIPP from the whole left ventricle was obtained using polar maps. The concentration of norepinephrine (NE: pg/ml) in the blood at rest was measured. The mean values of pulmonary artery pressure was measured in ten patients using Swan-Ganz catheter. 123I-BMIPP myocardial SPECT and measurement of NE were reexamined in 5 patients after mitral valvuloplasty. NE values were 476 +/- 72 and 793 +/- 286 in classes I + II and III + IV, respectively. NE values was increased in the severe heart failure group (p < 0.05). NE values were 480 +/- 69 and 743 +/- 295 in the mildly and severely stenotic groups, respectively. NE value was increased in severely stenotic group (p < 0.05). Twelve patients showed normal uptake on both 201Tl and 123I-BMIPP myocardial SPECT. Three patients showed slightly reduced uptake on both 201Tl and 123I-BMIPP myocardial SPECT. WR was 27.2 +/- 4.8% and 44.3 +/- 6.7% in class I + II and class III + IV, respectively. WR was increased in severe heart failure group (p < 0.05). WR was 27.8 +/- 6.0% and 41.3 +/- 9.4% in the mildly and severely stenotic group, respectively. WR was increased in the severely stenotic group (p < 0.05). NE was correlated with WR (p < 0.001). In patients with mitral valvuloplasty, WR was 44.3 +/- 6.7% and 31.4 +/- 4.7% before and after mitral valvuloplasty, respectively. NE values were 857 +/- 266 and 574 +/- 165, respectively. Both WR and NE were decreased after mitral valvuloplasty (p < 0.01). In patients with mitral stenosis, WR was increased in the severe heart failure group and severely stenotic group without apparent myocardial damage. Myocardial metabolism in the left ventricle might be influenced by right heart failure through, for example, NE and neurohormonal factors.
