    BACKGROUND: The mixing test is useful to investigate the cause of unexpectedly prolonged activated partial thromboplastin time (APTT). Several indexes are available for distinguishing correction from non-correction (ie, factor deficiency from inhibitors), but their performance characteristics may differ because of their different formulas. Furthermore, it is unclear how each index performs under the coexistence of factor deficiency and inhibitors. OBJECTIVES: The objective of this study was to examine the differences in indexes, depending on factor VIII activity (FVIII:C) levels and lupus anticoagulant (LA) titers in test samples. METHODS: APTT was measured in spiked samples with various FVIII:C levels and LA titers, normal pooled plasma (NPP), and their 4:1, 1:1, and 1:4 mixtures. The following 5 indexes were calculated: index of circulating anticoagulant, mixing test normalized ratio, 4:1 and 1:1 percent corrections, and an APTT difference between the 1:1 mixture and NPP. The samples with LA, showing correction, were measured for FVIII:C in a one-stage assay to check parallelism. RESULTS: All indexes showed correction under FVIII deficiency and non-correction under higher LA titers. However, under lower LA titers, some indexes showed non-correction but others showed correction because of dilution effects and variations in formulas and/or sample mix ratios. The differences among the indexes were more pronounced under coexistent FVIII deficiency and LA, even though LA titers were equal in the tested samples; samples with lower FVIII:C showed correction, whereas those with normal FVIII:C showed non-correction. The samples tested for FVIII:C showed non-parallelism. CONCLUSION: Each index had different performance characteristics to LA samples, which were pronounced under low FVIII:C levels in test samples.

    Neuroendocrine neoplasms of the colon and rectum are colorectal epithelial neoplasms with neuroendocrine differentiation. A platinum regimen used for small cell lung cancer is the currently recommended chemotherapy for gastroenteropancreatic neuroendocrine carcinomas (GEP-NECs), regardless of the organ. The BRAF V600E mutation has been recently reported as a druggable driver mutation in colorectal NECs. In BRAF V600E mutant colorectal cancer, a combination of BRAF inhibitor and anti-epidermal growth factor receptor (EGFR) antibody, with or without a MEK inhibitor, is recommended. Here, we report the case of 77-year-old man who had lymph node recurrence after surgery for primary ascending colonic NEC. Two cytotoxic regimens, cisplatin plus irinotecan and modified FOLFOX6, were administered as first- and second-line chemotherapies with no remarkable response observed. At this point, genetic analysis confirmed the tumor harbored a BRAF V600E mutation. Thus, a regimen of BRAF inhibitor plus anti-EGFR antibody was administered. After commencing this regimen, carcinoembryonic antigen levels decreased within normal range, and there was dramatic shrinkage of the lymph node metastases observed by chest and abdominal computed tomography scans. To our knowledge, this is the first reported case of a colorectal NEC responding to a BRAF inhibitor and anti-EGFR antibody.

    頻用されている2種の活性化部分トロンボプラスチン時間(APTT)試薬および近年発売された計3種のAPTT試薬を対象に、その特性を調べて比較し、また2通りの方法で基準範囲(NRIs)を設定し、その実用性や臨床的有用性を評価した。試薬はトロンボチェックAPTT(以下TC)、トロンボチェックAPTT-SLA(SLA)、レボヘムAPTT SLA(Revohem)を使用した。測定性能として同時再現性、開栓後安定性、抗凝固薬やループスアンチコアグラント(LA)、凝固因子に対する感受性を調べた結果、安定性と感受性で試薬間差を認めた。感受性の評価では、Revohemは両試薬よりヘパリン類やLA、各凝固因子に対する感受性が高かった。試薬間の相関は良好だが、標準主軸回帰の傾きは1.08〜1.72と大きく異なり、また乖離検体を多数認めた。その主な原因はどの試薬でもワルファリンとヘパリンであったが、相対的に、TCでは肝機能障害と直接経口抗凝固薬、SLAとRevohemではLAが多かった。いずれの試薬でも市販正常50検体のAPTT値から算出されたNRIsは臨床2081検体から算出されたNRIsより狭く、これは前者のNRIsの上限が後者より低く、また下限は高いことが実態であった。Revohemにおいて、正常50検体を用いたNRIsより臨床2081検体を用いたNRIsの方が添付文書のNRIsと近かった。TCでは36〜40秒、SLAでは35〜40秒、Revohemでは33〜40秒の検体のうち、他試薬でのAPTTが40秒以上であった検体について、その検体数とAPTT延長の背景を解析した。結果、TCでは24検体、SLAでは86検体、Revohemでは75検体あり、主なAPTT延長の背景はTCではLAとヘパリン、SLAとRevohemではワルファリンと肝機能障害であった。

    Hearing loss affects >5% of the global population and therefore, has a great social and clinical impact. Sensorineural hearing loss, which can be caused by different factors, such as acoustic trauma, aging, and administration of certain classes of drugs, stems primarily from a dysfunction of the cochlea in the inner ear. Few therapeutic strategies against sensorineural hearing loss are available. To develop effective treatments for this disease, it is crucial to precisely determine the behavior of ototoxic and therapeutic agents in the microenvironment of the cochlea in live animals. Since the 1980s, a number of studies have addressed this issue by different methodologies. However, there is much less information on pharmacokinetics in the cochlea than that in other organs; the delay in ontological pharmacology is likely due to technical difficulties with accessing the cochlea, a tiny organ that is encased with a bony wall and has a fine and complicated internal structure. In this review, we not only summarize the observations and insights obtained in classic and recent studies on pharmacokinetics in the cochlea but also describe relevant analytical techniques, with their strengths, limitations, and prospects.

    Background Congenital thrombotic thrombocytopenic purpura (cTTP), otherwise known as Upshaw-Schulman syndrome, is an extremely rare hereditary disease. Pregnancy is identified as a trigger for TTP episodes in patients with cTTP. Objectives To investigate the ideal management of pregnant patients with cTTP. Patients/Methods We identified 21 patients with a reproductive history (38 pregnancies) in a Japanese cTTP registry. Fetal outcomes were compared between two groups: group 1 (n = 12), pregnancy after diagnosis of confirmed cTTP byADAMTS13gene analysis; and group 2 (n = 26), pregnancy before diagnosis of confirmed cTTP. Results In group 1, ADAMTS13 activity was closely monitored until delivery in most cases. Among 10 pregnancies in group 1, prophylactic fresh frozen plasma (FFP) infusions during pregnancy were performed to replenish ADAMTS13. In group 2, prophylactic FFP infusions were not administrated in 23 pregnancies and FFP test infusions were performed in only three pregnancies. The live birth rate of group 1 was significantly higher than that of group 2 (91.7% vs 50.0%, respectively,P = .027). The fetal survival rates of women without FFP infusions were dramatically decreased after 20 weeks of gestation. The FFP infusion dosage in group 1 was generally higher than 5 mL/kg/wk by 20 weeks of gestation. Conclusions Our results indicate that FFP infusions of more than 5 mL/kg/wk should be initiated as soon as patients become pregnant. However, even with these infusions, patients with repeated TTP episodes before pregnancy might have difficulty giving birth successfully. Recombinant ADAMTS13 products might be new treatment options for pregnant patients with cTTP.

    【目的】凝固検査検体取扱いに関するコンセンサスでは示されていない分子マーカー検査や容量の大きい採血管を用いた凝固時間検査に適切な検体の遠心条件を調べる。【方法】13名の被験者を対象に実験1では一人につき2mL、実験2では一人につき5mLの検体を3本調製した。実験1では20℃の下、3通りの条件(1,500×gで15分、2,000×gで10分、3,500×gで6分)で検体を遠心し、血漿中残存血小板数、トロンビン-アンチトロンビン複合体(TAT)、フィブリンモノマー複合体、フィブリノゲン・フィブリン分解産物、Dダイマーを測定した。実験2では1,500×gで20℃の下、3通りの時間(10分、15分、20分)で検体を遠心し、血漿中残存血小板数を測定した。また、各遠心時間の検体を遠心直後および凍結融解後に希釈ラッセル蛇毒時間(dRVVT)を測定した。【結果】実験1ではどの条件でも残存血小板数は10×10^9/L未満であったが、遠心力上昇に伴いTATが有意に高値を示した。実験2では残存血小板数を10×10^9/L未満にするには20分以上遠心が必要であり、残存血小板数10×10^9/L以上の検体では凍結融解後のdRVVTが偽短縮した。【結論】分子マーカー検査、凝固時間検査ともに遠心力は1,500×gが推奨され、2mL採血管では15分以上、5mL採血管では20分以上の遠心が必要と考えられた。(著者抄録)

    The prognostic nutrition index (PNI), calculated based on serum albumin and lymphocyte counts, predicts the prognosis of several cancers, including operated esophageal cancers. In this study, we determined whether PNI could predict the occurrence of severe adverse events by chemotherapy and chemoradiotherapy, and overall survival in esophageal cancer. We collected data from 191 patients with esophageal cancer treated with at least one course of cisplatin and 5-fluorouracil from 2005 to 2016. We compared the incidences of severe adverse events and overall survival between a high- and a low-PNI group. The optimal cut-off value of the Onodera PNI was 43.2. Patients with low PNIs suffered more frequent severe adverse events than did those with high PNIs, and the latter patients survived longer. The PNI was independently prognostic of overall survival and stage. The PNI predicted the development of severe adverse events caused by chemotherapy or chemoradiotherapy, and overall survival, in esophageal cancer patients.

    <p>症例は75歳の女性。血液検査で貧血と末梢血に芽球を認められたため,当院を紹介受診した。骨髄穿刺で骨髄異形成症候群(myelodysplastic syndrome with excess blasts 2, MDS-EB-2)と診断された。血球減少の進行や芽球の増加,および出血症状はなく経過していた。診断から10ヶ月後,左手母指球に外傷を負い,内出血が持続し,止血困難となったため緊急入院した。血小板数は正常範囲であったが,血小板機能検査でコラーゲン凝集能とアラキドン酸凝集能の低下を認められた。抗血小板薬の内服はなく,またこれまで出血傾向の既往もなかったことから,MDSによる2次性の血小板機能低下による出血と判断し,血小板輸血を行い止血した。MDSの患者では,潜在的に血小板凝集能が低下していることが多く,血小板数の割に出血傾向が強い場合には血小板凝集能を調べ,血小板輸血などの治療介入を検討する必要がある。</p>

    Background/Aim: Inhibition of glutaminolysis has been reported as a promising therapeutic strategy to target several solid carcinomas. We aimed to investigate the effects of glutaminolysis on cell proliferation in lung squamous cell carcinoma cell lines and to explore the potential of targeting glutaminolysis as an anticancer strategy. Materials and Methods: Glutamine (Gln) dependence was assessed in six lung squamous cell carcinoma cell lines. Cell proliferation, mammalian target of rapamycin complex 1 (mTORC1) activity and the induction of autophagy were assessed after inhibition of glutaminolysis via Gln depletion or glutaminase (GLS) inhibition. Results: Five of six lung squamous cell carcinoma cell lines exhibited glutamine- dependence. The extent of dependence was correlated with the mRNA levels of GLS1/GLS2. Inhibition of glutaminolysis inhibited cell proliferation by down-regulating of mTORC1 signaling and inducing autophagy in Gln-dependent lung squamous cell carcinoma cell lines. Conclusion: Targeting glutaminolysis may represent a potential therapeutic strategy for the treatment of Gln-dependent lung squamous cell carcinomas.

    Myoepithelial carcinoma of the breast is an extremely rare tumor composed entirely of malignant spindle cells with myoepithelial differentiation. The majority of previously reported cases have mainly described the clinicopathological features of the disease, and few have presented cytogenetic data. We herein present the case of a 48-year-old woman who was admitted with a left sided breast lump in the inner upper quadrant that was initially diagnosed as a myoepithelioma with potentially malignant disorder. At 12 months after resection, she complained about a newly developed solid mass in the subareolar region of the ipsilateral breast that was diagnosed as an invasive ductal carcinoma. In addition, 16 months after the initial admission, a re-growing remnant lesion recurred in the inner upper quadrant and was ultimately diagnosed as a myoepithelial carcinoma. Lymph node metastasis of the myoepithelial carcinoma was also observed in her left axillary region 11 months after local recurrence. A cytogenetic analysis showed recurring specific chromosomal alterations both in the locally recurrent and in the lymph-node metastatic lesion: 48, XX, t(5;18)(q13;q23),del(6)(q?),+14. + marl. To our knowledge, this is the first published report of clonal chromosomal rearrangements in myoepithelial carcinoma of the breast that presented as metachronic double cancer with invasive ductal carcinoma in the ipsilateral breast.

    The American Society of Clinical Oncology provides clinical practice guidelines for appropriate cytotoxic chemotherapy dosing for obese adult patients with cancer. The panel recommends that actual body weight should be used when selecting cytotoxic chemotherapy doses regardless of obesity status. However, there have been no reports regarding the appropriate cytotoxic chemotherapy dosing for obese Japanese patients with cancer.
    We collected data from 216 gynecological cancer patients who were treated with at least one course of a paclitaxel and carboplatin (TC) regimen or a docetaxel and carboplatin (DC) regimen at Niigata University Medical and Dental Hospital from July 2006 to April 2014. Patients were divided into three groups according to body mass index (BMI): obese (BMI aeyen 25), normal (BMI 18.5-24.9), and underweight (BMI &lt; 18.5), as defined by the Japan Society for the Study of Obesity. We analyzed hematological toxicities by full weight-based chemotherapy in each group.
    The rates of grade 3/4 leukocytopenia, neutropenia, and thrombocytopenia were not significantly different among the three BMI groups on all patient analyses. For the TC regimen, the obese and normal groups had significantly lower leukocytopenia (grade 3/4) rates than did the underweight group. Also, significant positive correlations between BMI and the nadirs of leukocytes, neutrophils, platelets, and hemoglobin were observed. For the DC regimen, no significant difference was observed among the BMI groups and the rate of grade 3/4 hematological toxicities.
    We did not observe stronger myelosuppression in obese cancer patients compared with non-obese cancer patients. Therefore, the cytotoxic chemotherapy dose should be calculated by the actual body weight and unnecessary dose reduction should be avoided.

    Background: Conditioning regimens including total body irradiation (TBI) or cyclophosphamide can mobilize high-mobility group box 1 (HMGB1) to peripheral blood. Additionally, increased plasminogen activator inhibitor (PAI)-1 levels are associated with post-allogeneic hematopoietic stem cell transplantation (aHSCT). However, changes to circulating levels of HMGB1 after aHSCT are poorly understood. Materials and methods: The study cohort included 289 patients who underwent aHSCT at one of 25 institutions in Japan. We have investigated the relationship between HMGB1 and PAI-1 following aHSCT. A significant increase in HMGB1 levels occurred after conditioning treatment. Additionally, levels of HMGB1 at day 0 were significantly increased in TBI+ patients and cyclophosphamide/TBI patients. Conclusion: Our data revealed that an increased level of HMGB1 at day 0 following aHSCT correlates with increased PAI-1 after aHSCT, which is consistent with previous reports. Increased HMGB1 at day 0 after a conditioning regimen may play a role in transplantation-associated coagulopathy following aHSCT, because PAI-1 can accelerate procoagulant activity.

    We focused on the level of reduction of Wilms' tumor gene 1 (WT1) mRNA in bone marrow as minimal residual disease during chemotherapies in adult acute myeloid leukemia (AML) patients. Forty-eight patients were enrolled in this study. Log levels of reduction of WT1 mRNA transcript after induction therapy compared with those at diagnosis were associated with disease-free survival (DFS) (P = 0.0066) and overall survival (OS) (P = 0.0074) in patients who achieved complete remission. Also log levels of reduction of WT1 mRNA transcript after final consolidation therapy compared with those at diagnosis were associated with DFS (P = 0.015) and OS (P = 0.012). By multivariate analysis, log levels of reduction of WT1 mRNA transcript after induction therapy and after final consolidation therapy compared with those at diagnosis were extracted as risk factors for outcome. Our results suggest that early and deep reduction of tumor burden may be important for the outcome of AML patients. In addition, it may be useful for the decision to proceed with allogeneic SCT as post-remission therapy. (C) 2015 Elsevier Ltd. All rights reserved.

    A 23-year-old man was admitted to our hospital with severe thrombocytopaenia. He had unprotected sexual contact 6 weeks earlier. He was diagnosed with acute HIV infection by means of HIV RNA viral load testing and HIV-associated thrombocytopaenia. Although his thrombocytopaenia improved immediately with short-term dexamethasone therapy, this effect was not sustained after cessation of therapy. Antiretroviral therapy including raltegravir was initiated, and the patient recovered from severe thrombocytopaenia within several days. The findings from this case suggest that acute HIV infection should be suspected with unexplained thrombocytopaenia, and that antiretroviral therapy is the treatment of choice for severe HIV-associated thrombocytopaenia, even when in the early period following acquisition of the virus.

    We herein report the case of a leukemia patient who developed hepatitis E seven months after undergoing a transfusion with contaminated blood products. The latency period in this case was significantly longer than that of typical hepatitis E. Recently, chronic infection with hepatitis E virus (HEV) genotype 3 has been reported in immunocompromised patients. There is a possibility that our patient was unable to eliminate the virus due to immunosuppression following chemotherapy and the administration of steroids. The prevalence of HEV in healthy Japanese individuals is relatively high and constitutes a critical source of infection via transfusion. Hepatitis E is an important post-transfusion infection, and immunocompromised patients may exhibit a long latency period before developing the disease.

    Alveolar epithelial cells (AECs) differentiated from induced pluripotent stem cells (iPSCs) represent new opportunities in lung tissue engineering and cell therapy. In this study, we modified a two-step protocol for embryonic stem cells that resulted in a yield of similar to 9% surfactant protein C (SPC)(+) alveolar epithelial type II (AEC II) cells from mouse iPSCs in a 12-day period. The differentiated iPSCs showed morphological characteristics similar to those of AEC II cells. When differentiated iPSCs were seeded and cultured in a decellularized mouse lung scaffold, the cells reformed an alveolar structure and expressed SPC or T1 alpha protein (markers of AEC II or AEC I cells, respectively). Finally, the differentiated iPSCs were instilled intratracheally into a bleomycin-induced mouse acute lung injury model. The transplanted cells integrated into the lung alveolar structure and expressed SPC and T1 alpha. Significantly reduced lung inflammation and decreased collagen deposition were observed following differentiated iPSC transplantation. In conclusion, we report a simple and rapid protocol for in vitro differentiation of mouse iPSCs into AECs. Differentiated iPSCs show potential for regenerating three-dimensional alveolar lung structure and can be used to abrogate lung injury.

    We herein report the case of a 22-year-old woman with severe aplastic anemia who underwent allogeneic hematopoietic stem cell transplantation (HSCT). After HSCT, the Epstein-Barr virus (EBV)-DNA load in the peripheral blood gradually increased, and the patient presented with a fever and lymphadenopathy on day 56 post-HSCT. Although we administered rituximab, her clinical condition worsened. After rituximab treatment, CD8 T-cells emerged and became dominant in the peripheral blood, some of which were positive on an EBV-specific tetramer analysis. However, an open biopsy of the lymphadenopathy lesions revealed the CD8 T-cells to be infected with EBV, exhibiting proliferation with oligoclonality. The patient ultimately died of multiple organ failure on day 99 post-HSCT.

    We developed a new device involving an individual PT controlling system for neutron-scattering experiments available at 010GPa and at 77473K. Thanks to the thermal insulators made of zirconia and glass-fiber-reinforced plastic under the anvils, temperature only around anvils can be controllable with fast heating/cooling rate of&lt;20K/min, and it also allows us to use normal hydraulic oil even at low temperatures, which has much less risk of leaking compared with helium gas. The feasibility test for this system for neutron diffraction experiments for ice VIII shows that the full decompression is established without any technical difficulty, which used to be not straightforward by the previous systems.

    A 51-year-old man was admitted due to a severe bleeding tendency. After he was diagnosed with immune thrombocytopenia (ITP), several therapies, including steroids, steroid pulse, vincristine and rituximab, were administered; however, the patient's bleeding symptoms were not sufficiently controllable with these treatments. Subsequently, a diffuse alveolar hemorrhage was observed. Treatment with a thrombopoietin receptor agonist, romiplostim, was initiated to prevent lethal hemorrhaging, although the efficacy of thrombopoietic receptor agonists in such emergency situations has not been elucidated. The initiation of romiplostim achieved prompt remission in platelets. This case suggests that combination therapy with romiplostim, rituximab and vincristine is effective in cases of newly diagnosed severe therapy-resistant ITP.

    To synthesize long-acting and antiangiogenic erythropoietin to be clinically applied for treatment of patients with solid tumors, we synthesized a hybrid molecule of human erythropoietin added onto the C-terminus with a heparin-binding motif of human PLGF-2 to develop a novel derivative of long-acting and antiangiogenic erythropoietin: heparin-binding erythropoietin (HEPO), and studied the characteristics of this novel erythropoietin derivative. HEPO cDNA was synthesized, expressed in insect cells, and the protein was purified using a heparin-sepharose affinity column. The erythropoietic and angiogenic effects of the partially purified protein were analyzed in vitro and in vivo. The erythropoietic activity of the protein was equivalent to natural EPO in vitro. In vivo administration of the protein to mice revealed its long-acting erythropoietic activity as expected. Administration of the protein inhibited angiogenesis in a mouse limb ischemia model. In conclusion, the heparin-binding motif of PLGF-2 may act as, so to speak, a superendostatin. This novel long-acting erythropoietin derivative may have an advantage to inhibit tumor growth while preserving hematopoietic and tissue-protective effects.

    We describe a 60-year-old Japanese patient with chronic myeloid leukemia (CML) who developed myelodysplastic syndrome (MDS) with Ph negative monosomy 7 chromosome following transient bone marrow dysplasia during imatinib treatment. Most cases that developed chromosomal abnormality in Ph negative cells during imatinib therapy were reported to have less clinical implications, while rare cases developed MDS/AML. The present case suggested that metaphase karyotype analysis and bone marrow examination should be performed for the long term follow-up under imatinib treatment in cases showing cytopenia. The results also suggested that monosomy 7 in Ph negative cells may be an indicator of a poor prognosis.

    Pharmacological study is predictably effective in establishing an optimal monitoring strategy for the usage of cyclosporine A (CsA) to prevent graft-versus-host disease (GVHD) in allogeneic hematopoietic stem cell transplantation recipients. Pharmacokinetic profiling of 33 recipients administered CsA twice daily by 3-h intravenous infusion revealed that levels peaked 2-3 h after the start of infusion, and an exponential decline of CsA concentrations after the termination of infusion was observed. The correlation between the area under the curve (AUC(0-12)) and CsA concentration at various time points after infusion revealed that C (2) and C (3) correlated best with AUC(0-12) (r (2) = 0.725), while the trough concentration correlated poorly. Ex vivo T cell stimulation followed by intracellular cytokine detection with flow cytometry revealed that the capacity of T cells to produce cytokines upon stimulation was inversely proportional to the CsA concentration, and reached a minimum at about 700 ng/mL with a marginal decrease above this concentration. Extrapolation using the regression equations of this study and the data from our retrospective study leads to the assumption that the dose adjustment of CsA based on maintaining the C (3) concentration above 800 ng/mL may effectively prevent acute GVHD. To confirm this assumption, a prospective clinical study is required.

    Bone marrow implantation (BMI) has been utilized for the treatment of limb ischemia, however, serum markers have not yet been reported to express the degree of limb ischemia. We analyzed the serum levels of several cytokines including erythropoietin (EPO) in the treated legs and the contralateral ones in 11 patients with limb ischemia treated with BMI. The EPO level in the pre-treated legs in the 5 patients with arteriosclerosis obliterans revealed a good correlation with ankle-brachial pressure index. The EPO level, but not the levels of TNF-alpha, VEGF, and bFGF in the pre-treated legs was significantly higher than that in the contralateral legs in the 11 patients, and the EPO level decreased in 4 weeks after BMI. The serum EPO level may express the degree of limb ischemia presumably through the reactive production of EPO in ischemic tissue. (C) 2007 Elsevier Ireland Ltd. All rights reserved.

    Restenosis is a major problem in percutaneous catheter intervension (PCT) for coronary artery stenosis in patients with acute myocardial infarction. Coronary restenosis arises from intimal hyperplasia, i.e., hyperplasia of the vascular smooth muscle cells (SMCs) caused by endothelial cell (EC) damage due to PCT. Drug eluting stent (DES), a novel stent coated with a cell-growth inhibitor, such as rapamycin, has been utilized to block SMC proliferation, but DES also blocks EC repair and thus requires the administration of anti-platelets for a lone, time to prevent thrombus formation after PCT. Moreover, insufficient prevention of platelet aggregation sometimes induces restenosis after PCT. One of the signal transduction inhibitors, imatinib mesilate, blocks tyrosine kinase activity of platelet-derived growth factor receptor (PDGFR), and therefore it may block the development of neointima through growth inhibition of SMCs without the obstructive effect on EC-repair. We therefore studied the effects of imatinib on neointimal hyperplasia in a balloon injury model of rat carotid arteries. Rats were orally administered with imatinib for 14 days after balloon injury, and sacrificed to analyze the neointimal formation. Intimal hyperplasia was inhibited by imatinib in a dose-dependent manner. Therefore imatinib presumably obstructed the growth of SMCs via interception on growth-signaling of PDGFR. The administration of imatinib after coronary stenting or the use of an imatinib-eluting stent may further reduce the risk of restenosis in patients.

    Objectives. Autologous bone marrow implantation (BMI) is effective to treat critical limb ischemia, but the long-term prognosis is not clear. The outcome of BMI treatment for ischemic legs was investigated related to the clinical background of the patient, and short-term effects of BMI. The end event was defined as unexpected lower limb amputation. Methods and Results. This study included 21 consecutive patients (mean age 60.0 ± 13.6 years) with peripheral arterial disease who underwent BMI between December 2001 and March 2005. Twelve patients had arteriosclerosis obliterans (ASO), 5 had Buerger disease (thromboangiitis obliterans), 3 had thromboembolism, and 1 had hypereosinophilic syndrome. The patients with ASO had severe complications such as diabetes and hyperlipidemia. The total number of transplanted CD34-positive cells, ankle-brachial pressure index (ABI), and tissue oxygen pressure (TcO 2) were lower in ASO patients than non-ASO patients. Significant risk factors for the event were diagnosis of ASO and low TcO2 (&lt
    30 mmHg) according to the Kaplan-Meier survival curve and log rank test. All 6 patients who required limb amputation had ASO simultaneously with low TcO 2 (6 of 9, 67%). In contrast, there was no correlation between the end event and short-term effect of BMI such as improvements in ABI and TcO 2. Conclusions. Treatment with BMI could not save legs in some patients with ASO associated with severe leg ischemia.

    Bone marrow cell implantation (BMI) has been utilized to treat patients with limb and heart ischemia. BMI provides angiogenic precursors and angiogenic cytokine-producing cells, especially erythroid cells. In this study, we induced in vitro angiogenesis cultures and in vivo BMI simulation using a marine limb ischemia model to examine the role of erythroid cells and the effect of erythropoietin (EPO). Human erythroid colonies (BFU-e) induced capillary networks around the colonies in vitro. Erythroid cells in human bone marrow produced vascular endothelial growth factor and placental growth factor. The angiogenic effects of erythroid cells were further amplified in the presence of EPO. Limb-ischemic mice were treated with BMI +/- EPO, and limb survival, blood flow recovery, and muscle histology were analyzed. Treatment with whole bone marrow cells + EPO significantly improved limb survival and blood flow. The cumulative effects of EPO on BMI induced and increase in capillary number and artery enlargement. Erythroid cells were essential for the in vivo effects of BMI, and CD14-positive cells supported the biological effects. In addition to the direct effect of EPO on angiogenesis, EPO showed indirect effect on angiogenesis through amplifying the angiogenic effects by erythroid cells supported by CD14-positive cells.

    Therapy related acute myelogenous leukemia in a 55-year-old Japanese woman is described. She had been treated for a diagnosis of non-Hodgkin's lymphoma 2 years before the onset of the secondary leukemia. She was diagnosed as AML (FAB: M2) with monosomy 7, and successfully treated by an intensive combination chemotherapy followed by an autologous peripheral blood stem cell transplantation. The disease relapsed shortly after the treatment, and the karyotype analysis revealed a complex abnormality accompanied with t(9; 11)(p22;q23), however, monosomy 7 was absent. Southern blotting analysis was performed, and MLL rearrangement was evident in both the bone marrow samples obtained at that time and the cryopreserved marrow cells obtained at the onset of the disease. The bone marrow sample stored in a Camoy solution at the onset was further analyzed, and three karyotype panels showing 45,XX, -7, t(9;11)(p22;q23) were found. Like this situation, a masked MLL rearrangement may have existed in some cases with hematopoictic malignancies, and appear to be disclosed in the clinical course. (C) 2002 Elsevier Science Ltd.

    直接経口抗凝固薬(DOAC)の登場は、抗凝固療法を劇的に変化させた。特に従来の抗凝固薬と異なり、相互作用が少なく、モニタリング検査が不要という利点がある。一方で、血栓の増大・再発や、出血などの合併症も少なくない。そのため、より有効かつ安全な治療のためには「薬物血中濃度」を測定し、かつ「抗凝固活性」を評価して、「臨床所見」と組み合わせて検討することが求められる。
    近年、新潟大学医学部を中心に、簡便かつ低コストで薬物血中濃度が測定可能な「ダイヤモンド電極法」が開発された。本申請課題では、ダイヤモンド電極法によるDOACの血中濃度測定が可能かを検証する。さらに実際の臨床所見や凝固線溶検査、抗凝固活性測定も含めた、包括的なモニタリング検査を開発し、実臨床への治療的応用を検討することを目的とする。
    2021年度も、DOACの中で特にエドキサバンの測定の最適化を推進した。当グループのダイヤモンドセンサによる測定感度と選択性の向上を目指し、血漿サンプル前処理の方法を最適化することを検討した。まず標本として、ラットの血液に既知濃度のイマチニブを溶解したものを使用した。血漿サンプルにアセトニトリル添加の上、遠心分離し、除蛋白質処理した。これにより血漿蛋白質に結合したエドキサバンを分離する最適なアセトニトリル量を検討した。さらに、各種遠心式フィルタを用いて、血漿中からエドキサバンのみを抽出する方法もいくつか試みた。
