Visual acuity in the right eye was 20/222, with submacular hemorrhage (SMH) and Henle fiber layer hemorrhage (HFLh) due to retinal arterial macroaneurysm (RAM) rupture. She underwent SMH displacement, including cataract surgery, vitrectomy, intravitreal injection of tissue-plasminogen activator, and air tamponade. Three months postoperatively the SMH and HFLh had disappeared and visual acuity had improved to 20/200. Six months postoperatively, a macular hole had developed. We performed an inverted internal limiting membrane flap and gas tamponade. Ten months later, the hole had closed and visual acuity had improved to 20/100. en-copyright= kn-copyright= en-aut-name=AkatsukaRiku en-aut-sei=Akatsuka en-aut-mei=Riku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimuraShuhei en-aut-sei=Kimura en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatobaRyo en-aut-sei=Matoba en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Morizane HosokawaMio en-aut-sei=Morizane Hosokawa en-aut-mei=Mio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShiodeYusuke en-aut-sei=Shiode en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MoritaTetsuro en-aut-sei=Morita en-aut-mei=Tetsuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=DoiShinichiro en-aut-sei=Doi en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MorizaneYuki en-aut-sei=Morizane en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=submacular hemorrhage kn-keyword=submacular hemorrhage en-keyword=Henle fiber layer hemorrhage kn-keyword=Henle fiber layer hemorrhage en-keyword=retinal arterial macroaneurysm rupture kn-keyword=retinal arterial macroaneurysm rupture en-keyword=macular hole kn-keyword=macular hole en-keyword=inverted internal limiting membrane flap technique kn-keyword=inverted internal limiting membrane flap technique END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=1 article-no= start-page=39 end-page=45 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Could the Trabecular Bone Score Be a Complementary Tool for Evaluating Degenerative Lumbar Vertebrae? en-subtitle= kn-subtitle= en-abstract= kn-abstract=Evaluating vertebral bone mass and quality in the elderly poses challenges due to degenerative changes. This study aims to elucidate the usefulness of the trabecular bone score (TBS) by examining the relationship between bone mineral density (BMD), TBS, and Hounsfield unit (HU) values. A retrospective analysis of 599 vertebrae from 152 patients (mean age 69.0 years; range 44-89; 74 males and 78 females) undergoing dual-energy X-ray absorptiometry (DXA) and CT scans was conducted. Vertebrae were categorized into three grades based on the degree of degeneration. The TBS was calculated from DXA images, and the HU value was measured by placing a region of interest on an axial image of the vertebral mid-body. One-way analysis of variance and Pearson’s correlation tests were employed to investigate the relationship between BMD and TBS or HU values. While lumbar BMD significantly increased (p<0.01) with degenerative changes, TBS and HU values showed no significant differences. The correlations between lumbar BMD and TBS values, and between BMD and HU values, were stronger without degenerative changes than with degenerative changes. Significantly different HU values were observed between the right and left sides of severely degenerated vertebrae. Severe degenerative changes, particularly those associated with sclerosis, may impact HU values. TBS exhibits greater potential than HU values as a complementary tool. en-copyright= kn-copyright= en-aut-name=TakaoShinichiro en-aut-sei=Takao en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MisawaHaruo en-aut-sei=Misawa en-aut-mei=Haruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TetsunagaTomoko en-aut-sei=Tetsunaga en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShinoharaKensuke en-aut-sei=Shinohara en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamaneKentaro en-aut-sei=Yamane en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OdaYoshiaki en-aut-sei=Oda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsujiHironori en-aut-sei=Tsuji en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KajikiYuya en-aut-sei=Kajiki en-aut-mei=Yuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=trabecular bone score kn-keyword=trabecular bone score en-keyword=computed tomography Hounsfield unit kn-keyword=computed tomography Hounsfield unit en-keyword=lumbar degenerative change kn-keyword=lumbar degenerative change en-keyword=radiodensity kn-keyword=radiodensity END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=10 article-no= start-page=251 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241014 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Searching Method for Three-Dimensional Puncture Route to Support Computed Tomography-Guided Percutaneous Puncture en-subtitle= kn-subtitle= en-abstract= kn-abstract=In CT-guided percutaneous punctures-an image-guided puncture method using CT images-physicians treat targets such as lung tumors, liver tumors, renal tumors, and intervertebral abscesses by inserting a puncture needle into the body from the exterior while viewing images. By recognizing two-dimensional CT images prior to a procedure, a physician determines the least invasive puncture route for the patient. Therefore, the candidate puncture route is limited to a two-dimensional region along the cross section of the human body. In this paper, we aim to construct a three-dimensional puncture space based on multiple two-dimensional CT images to search for a safer and shorter puncture route for a given patient. If all puncture routes starting from a target in the three-dimensional space were examined from all directions (the brute-force method), the processing time to derive the puncture route would be very long. We propose a more efficient method for three-dimensional puncture route selection in CT-guided percutaneous punctures. The proposed method extends the ray-tracing method, which quickly derives a line segment from a given start point to an end point on a two-dimensional plane, and applies it to three-dimensional space. During actual puncture route selection, a physician can use CT images to derive a three-dimensional puncture route that is safe for the patient and minimizes the puncture time. The main novelty is that we propose a method for deriving a three-dimensional puncture route within the allowed time in an actual puncture. The main goal is for physicians to select the puncture route they will use in the actual surgery from among the multiple three-dimensional puncture route candidates derived using the proposed method. The proposed method derives a three-dimensional puncture route within the allowed time in an actual puncture. Physicians can use the proposed method to derive a new puncture route, reducing the burden on patients and improving physician skills. In the evaluation results of a computer simulation, for a 3D CT image created by combining 170 two-dimensional CT images, the processing time for deriving the puncture route using the proposed method was approximately 59.4 s. The shortest length of the puncture route from the starting point to the target was between 20 mm and 22 mm. The search time for a three-dimensional human body consisting of 15 CT images was 4.77 s for the proposed method and 2599.0 s for a brute-force method. In a questionnaire, physicians who actually perform puncture treatments evaluated the candidate puncture routes derived by the proposed method. We confirmed that physicians could actually use these candidates as a puncture route. en-copyright= kn-copyright= en-aut-name=GotohYusuke en-aut-sei=Gotoh en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakedaAoi en-aut-sei=Takeda en-aut-mei=Aoi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MasuiKoji en-aut-sei=Masui en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakaiKoji en-aut-sei=Sakai en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujimotoManato en-aut-sei=Fujimoto en-aut-mei=Manato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Department of Radiology, Kyoto Prefectural University of Medicine kn-affil= affil-num=4 en-affil=Department of Radiology, Kyoto Prefectural University of Medicine kn-affil= affil-num=5 en-affil=Graduate School of Informatics, Osaka Metropolitan University kn-affil= en-keyword=CT-guided percutaneous puncture kn-keyword=CT-guided percutaneous puncture en-keyword=searching method kn-keyword=searching method en-keyword=three-dimensional puncture route kn-keyword=three-dimensional puncture route END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=5 article-no= start-page=377 end-page=386 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prognostic Efficacy of the Albumin Grade in Patients with Hepatocellular Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=We previously found that “albumin grade”, formerly called the “ALBS grade,” demonstrated significant capability for prognostic stratification in hepatocellular carcinoma (HCC) patients treated with lenvatinib. The purpose of the present study was to compare the performance of the albumin grade with that of the modified albumin-bilirubin (mALBI) grade in predicting overall survival of HCC patients with different BCLC stages and treatment types. We enrolled 7,645 Japanese patients newly diagnosed with HCC using the Akaike information criteria (AIC), likelihood ratio, and C-index in different Barcelona Clinic Liver Cancer (BCLC) stages and treatments. The albumin grade showed similar and slightly better performance than the mALBI grade for BCLC stage 0 and A and especially for patients who underwent curative surgery and ablation. In patients treated with transcatheter arterial chemoembolization, molecular targeted agents, and the best supportive care, the mALBI grade had better performance than the albumin grade. However, the differences of the indices were very small in all scenarios. Overall, the albumin grade was comparable in efficacy to the mALBI grade, showing particular benefit for patients with early-stage HCC. en-copyright= kn-copyright= en-aut-name=HiranoYuichi

The present study aimed to clarify the association between the effects of zolpidem and inflammation in mice treated with lipopolysaccharide (LPS), a known model of inflammation. We assessed the zolpidem-induced loss of righting reflex (LORR) duration 24 h after LPS treatment in mice. Additionally, the expressions of γ-aminobutyric acid (GABA)A receptor subunit and K+-Cl− cotransporter isoform 2 (KCC2) mRNA in the hippocampus and frontal cortex were examined in LPS-treated mice. Pretreatment with LPS was associated with significantly prolonged duration of zolpidem-induced LORR compared to control mice. This effect was significantly attenuated by administering bicuculline, a GABAA receptor antagonist, or flumazenil, a benzodiazepine receptor antagonist, in LPS-treated mice. Compared to controls, LPS-treated mice showed no significant change in the expression of GABAA receptor subunits in the hippocampus or frontal cortex. Bumetanide, an Na+-K+-2Cl− cotransporter isoform 1 blocker, attenuated the extended duration of zolpidem-induced LORR observed in LPS-treated mice. LPS significantly decreased Kcc2 mRNA expression in the hippocampus and the frontal cortex. These findings suggest that inflammation increases zolpidem-induced LORR, possibly through a reduction in KCC2 expression. en-copyright= kn-copyright= en-aut-name=WadaYudai en-aut-sei=Wada en-aut-mei=Yudai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UshioSoichiro en-aut-sei=Ushio en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KitamuraYoshihisa en-aut-sei=Kitamura en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SendoToshiaki en-aut-sei=Sendo en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Clinical Pharmacy, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Clinical Pharmacy, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Clinical Pharmacy, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Clinical Pharmacy, Okayama University, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=lipopolysaccharide kn-keyword=lipopolysaccharide en-keyword=zolpidem kn-keyword=zolpidem en-keyword=GABAA receptor kn-keyword=GABAA receptor en-keyword=K+-Cl− cotransporters kn-keyword=K+-Cl− cotransporters END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=185 end-page=191 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reduced Immunogenicity of COVID-19 Vaccine in Obese Patients with Type 2 Diabetes: A Cross-Sectional Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=The global pandemic of coronavirus infection 2019 (COVID-19) was an unprecedented public health emergency. Several clinical studies reported that heart disease, lung disease, diabetes, hypertension, dyslipidemia, and obesity are critical risk factors for increased severity of and hospitalization for COVID-19. This is largely because patients with these underlying medical conditions can show poor immune responses to the COVID-19 vaccinations. Diabetes is one of the underlying conditions most highly associated with COVID-19 susceptibility and is considered a predictor of poor prognosis of COVID-19. We therefore investigated factors that influence the anti-SARS-CoV-2 spike IgG antibody titer after three doses of vaccination in patients with type 2 diabetes. We found that obesity was associated with low anti-SARS-CoV-2 spike IgG antibody titers following three-dose vaccination in type 2 diabetics. Obese patients with type 2 diabetes may have attenuated vaccine efficacy and require additional vaccination; continuous infection control should be considered in such patients. en-copyright= kn-copyright= en-aut-name=TakahashiHiroko en-aut-sei=Takahashi en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EguchiJun en-aut-sei=Eguchi en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeMayu en-aut-sei=Watanabe en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakayamaMasanori en-aut-sei=Nakayama en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology, and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology, and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology, and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Office of Innovative Medicine, Organization for Research Strategy and Development, Okayama University kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology, and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=obesity kn-keyword=obesity en-keyword=type 2 diabetes kn-keyword=type 2 diabetes en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=vaccination kn-keyword=vaccination END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=163 end-page=170 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Impact of Light Touch and Pin Prick on Functional Outcomes in Patients with Traumatic Spinal Cord Injury en-subtitle= kn-subtitle= en-abstract= kn-abstract=A spinal cord injury (SCI) can cause severe lifelong functional disability and profoundly affect an individual’s daily life. We investigated the prediction of patients’ post-SCI functional outcomes by evaluating sensory scores rather than motor scores, as the latter’s association with functional outcomes is well established. We examined patients’ responses to a light touch (LT) and pin prick (PP) at admission and the response data’s usefulness as predictors of functional outcomes (i.e., ability to perform activities of daily living) at discharge. This exploratory observational study used data from the Japanese National Spinal Cord Injury Database (SCI-J). Data from 3,676 patients who met the inclusion criteria and were admitted for an SCI between 1997 and 2020 were analyzed. The motor score of the Functional Independence Measure (mFIM) at discharge was used as an index of functional outcome. A multiple regression analysis revealed that the mFIM was associated with both the LT response (β=0.07 (0.01), p<0.001) and the PP response (β=0.07 (0.01), p<0.001) at admission. The false discovery rate log-worth values for LT and PP were 6.6 and 8.5, respectively. Our findings demonstrate that LT and PP scores at admission can help predict patients’ functional outcomes after an SCI, although the magnitude of their contributions is not high. en-copyright= kn-copyright= en-aut-name=DeguchiTakayuki en-aut-sei=Deguchi en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KandaKanae en-aut-sei=Kanda en-aut-mei=Kanae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FurusawaKazunari en-aut-sei=Furusawa en-aut-mei=Kazunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Nlandu Roger Ngatu en-aut-sei=Nlandu Roger Ngatu en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiraoTomohiro en-aut-sei=Hirao en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Rehabilitation, Kagawa Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= affil-num=3 en-affil=Department of Rehabilitation Medicine, Kibikogen Rehabilitation Center for Employment Injuries kn-affil= affil-num=4 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= affil-num=5 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= en-keyword=functional independence measure kn-keyword=functional independence measure en-keyword=light touch kn-keyword=light touch en-keyword=pin prick kn-keyword=pin prick en-keyword=spinal cord injury kn-keyword=spinal cord injury en-keyword=Japanese National Spinal Cord Injury Database kn-keyword=Japanese National Spinal Cord Injury Database END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=115 end-page=122 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impacts of Age and Gender on Brain Edema in a Mouse Water Intoxication Model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Brain edema causes abnormal fluid retention and can be fatal in severe cases. Although it develops in various diseases, most treatments for brain edema are classical. We analyzed the impacts of age and gender on the characteristics of a water intoxication model that induces pure brain edema in mice and examined the model’s usefulness for research regarding new treatments for brain edema. C57BL/6J mice received an intraperitoneal administration of 10% body weight distilled water, and we calculated the brain water content by measuring the brain-tissue weight immediately after dissection and after drying. We analyzed 8-OHdG and caspase-3 values to investigate the brain damage. We also applied this model in aquaporin 4 knockout (AQP4−) mice and compared these mice with wild-type mice. The changes in water content differed by age and gender, and the 8-OHdG and caspase-3 values differed by age. Suppression of brain edema by AQP4− was also confirmed. These results clarified the differences in the onset of brain edema by age and gender, highlighting the importance of considering the age and gender of model animals. Similar studies using genetically modified mice are also possible. Our findings indicate that this water intoxication model is effective for explorations of new brain edema treatments. en-copyright= kn-copyright= en-aut-name=Nakamura-MaruyamaEmi en-aut-sei=Nakamura-Maruyama en-aut-mei=Emi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IrieKeiichiro en-aut-sei=Irie en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NaritaKazuhiko en-aut-sei=Narita en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HimiNaoyuki en-aut-sei=Himi en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyamotoOsamu en-aut-sei=Miyamoto en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakamuraTakehiro en-aut-sei=Nakamura en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Physiology2, Kawasaki Medical School kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=3 en-affil=Department of Physiology2, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Physiology2, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of Physiology2, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of Physiology2, Kawasaki Medical School kn-affil= en-keyword=brain edema kn-keyword=brain edema en-keyword=water intoxication model kn-keyword=water intoxication model en-keyword=age kn-keyword=age en-keyword=gender kn-keyword=gender en-keyword=AQP4 kn-keyword=AQP4 END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=499 end-page=509 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Neurological Analysis Based on the Terminal End of the Spinal Cord and the Narrowest Level of Injured Spine in Thoracolumbar Spinal Injuries en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to clarify neurological differences among the epiconus, conus medullaris, and cauda equina syndromes. Eighty-seven patients who underwent surgery for acute thoracolumbar spinal injuries were assessed. We defined the epiconus as the region from the terminal end of the spinal cord to the proximal 1.0 to 2.25 vertebral bodies, the conus medullaris as the region proximal to < 1.0 vertebral bodies, and the cauda equina as the distal part of the nerve roots originating from the spinal cord. On the basis of the distance from the terminal end of the spinal cord to the narrowest level of the spinal canal, the narrowest levels were ordered as follows: the epiconus followed by the conus medullaris and cauda equina. The narrowest levels were the epiconus in 22 patients, conus medullaris in 37 patients, and cauda equina in 25 patients. On admission, significantly more patients had a narrowed epiconus of Frankel grades A-C than a narrowed cauda equina. At the final follow-up, there were no significant differences in neurological recovery among those with epiconus, conus medullaris, or cauda equina syndrome. Anatomically classifying the narrowest lesion is useful for clarifying the differences and similarities among these three syndromes. en-copyright= kn-copyright= en-aut-name=HatakeyamaYuji en-aut-sei=Hatakeyama en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HongoMichio en-aut-sei=Hongo en-aut-mei=Michio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KidoTadato en-aut-sei=Kido en-aut-mei=Tadato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UrayamaMasakazu en-aut-sei=Urayama en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KasukawaYuji en-aut-sei=Kasukawa en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SasakiHiroshi en-aut-sei=Sasaki en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AizawaToshiaki en-aut-sei=Aizawa en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KudoDaisuke en-aut-sei=Kudo en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KimuraRyota en-aut-sei=Kimura en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OnoYuichi en-aut-sei=Ono en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KasamaFumihito en-aut-sei=Kasama en-aut-mei=Fumihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MiyakoshiNaohisa en-aut-sei=Miyakoshi en-aut-mei=Naohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Akita Red Cross Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Akita Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Ogachi Central Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Noshiro Kousei Medical Center kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Kitaakita Municipal Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Akita Red Cross Hospital kn-affil= affil-num=11 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=12 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= en-keyword=thoracolumbar spinal injury kn-keyword=thoracolumbar spinal injury en-keyword=terminal end of spinal cord kn-keyword=terminal end of spinal cord en-keyword=conus medullaris kn-keyword=conus medullaris en-keyword=epiconus syndrome kn-keyword=epiconus syndrome en-keyword=cauda equina syndrome kn-keyword=cauda equina syndrome END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=6 article-no= start-page=731 end-page=736 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Rare Case of Idiopathic Spinal Cord Herniation Treated by DuraGen® Collagen Matrix Graft en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a rare case of idiopathic spinal cord herniation (ISCH) with a history of cerebrospinal fluid (CSF) leakage. ISCH is a protrusion of the spinal cord through a dural defect. Thin constructive interference in steady-state (CISS) images clearly demonstrated the herniated cord in the present case. The myelopathy worsened and the patient underwent surgery for reduction of herniated spinal cord; the dural defect was filled by placing collagen matrix graft (DuraGen®) between the inner and outer dural layers. The patient’s symptoms have improved without relapse for 8 months since surgery. This method may be a good surgical option for cases of spinal cord herniation. en-copyright= kn-copyright= en-aut-name=KamamuraMaho en-aut-sei=Kamamura en-aut-mei=Maho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SasadaSusumu en-aut-sei=Sasada en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsushitaToshi en-aut-sei=Matsushita en-aut-mei=Toshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Division of Radiological Technology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=cerebrospinal fluid leakage kn-keyword=cerebrospinal fluid leakage en-keyword=constructive interference in steady state kn-keyword=constructive interference in steady state en-keyword=collagen matrix graft kn-keyword=collagen matrix graft en-keyword=magnetic resonance image kn-keyword=magnetic resonance image en-keyword=spinal cord herniation kn-keyword=spinal cord herniation END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=6 article-no= start-page=695 end-page=703 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=History of Transcatheter Arterial Chemoembolization Predicts the Efficacy of Hepatic Arterial Infusion Chemotherapy in Hepatocellular Carcinoma Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study sought to identify factors that are predictive of a therapeutic response to hepatic arterial infusion chemotherapy (HAIC) by focusing on the number of prior transcatheter arterial chemoembolization (TACE) sessions. To determine the parameters predicting a good response to HAIC, we retrospectively analyzed 170 patients with hepatocellular carcinoma (HCC) who received HAIC regimens comprising low-dose cisplatin combined with 5-fluorouracil (LFP) or cisplatin (CDDP) for the first time. In both the LFP and CDDP regimens, the response rates were significantly lower in patients with three or more prior TACE sessions than in those with two or fewer prior TACE sessions (LFP 57% versus 28%; p=0.01, CDDP 27% versus 6%; p=0.01). Multivariable logistic regression analysis revealed that the number of prior TACE sessions (≥ 3) was significantly associated with non-responder status (odds ratio 4.17, 95% Confidence Interval (CI) 1.76-9.86) in addition to the HAIC regimen. Multivariable analysis using the Cox proportional hazards model revealed that a larger number of prior TACE sessions (≥ 3) was a significant risk factor for survival (hazard ratio 1.60, 95% CI 1.12-2.29) in addition to Child-Pugh class, serum alpha-fetoprotein concentration, and maximum diameter of HCC. HCC patients who receive fewer prior TACE sessions (≤ 2) were found to be better responders to HAIC. en-copyright= kn-copyright= en-aut-name=OnishiHideki en-aut-sei=Onishi en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NousoKazuhiro en-aut-sei=Nouso en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakakiAkinobu en-aut-sei=Takaki en-aut-mei=Akinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OyamaAtsushi en-aut-sei=Oyama en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AdachiTakuya en-aut-sei=Adachi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=WadaNozomu en-aut-sei=Wada en-aut-mei=Nozomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakeuchiYasuto en-aut-sei=Takeuchi en-aut-mei=Yasuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShirahaHidenori en-aut-sei=Shiraha en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=hepatic arterial infusion chemotherapy kn-keyword=hepatic arterial infusion chemotherapy en-keyword=hepatocellular carcinoma kn-keyword=hepatocellular carcinoma en-keyword=refractory kn-keyword=refractory en-keyword=transcatheter arterial chemoembolization kn-keyword=transcatheter arterial chemoembolization END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=6 article-no= start-page=661 end-page=671 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association of Genetic Polymorphism with Taxane-induced Peripheral Neuropathy: Sub-analysis of a Randomized Phase II Study to Determine the Optimal Dose of 3-week Cycle Nab-Paclitaxel in Metastatic Breast Cancer Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chemotherapy-induced peripheral neuropathy (CIPN) is an important clinical challenge that threatens patients’ quality of life. This sub-study of the ABROAD trial investigated the influence of single nucleotide polymorphisms (SNPs) on CIPN, using genotype data from a randomized study to determine the optimal dose of a 3-week-cycle regimen of nab-paclitaxel (q3w nab-PTX) in patients with metastatic breast cancer (MBC). Patients with HER2-negative MBC were randomly assigned to three doses of q3w nab-PTX (SD: 260 mg/m2 vs. MD: 220 mg/m2 vs. LD: 180 mg/m2). Five SNPs (EPHA4-rs17348202, EPHA5-rs7349683, EPHA6-rs301927, LIMK2-rs5749248, and XKR4-rs4737264) were analyzed based on the results of a previous genome-wide association study. Per-allele SNP associations were assessed by a Cox regression to model the cumulative dose of nab-PTX up to the onset of severe or worsening sensory neuropathy. A total of 141 patients were enrolled in the parent study; 91(65%) were included in this sub-study. Worsening of CIPN was significantly greater in the cases with XKR4 AC compared to those with a homozygote AA (HR 1.86, 95%CI: 1.00001−3.46, p=0.049). There was no significant correlation of CIPN with any other SNP. A multivariate analysis showed that the cumulative dose of nab-PTX was most strongly correlated with CIPN (p<0.01). en-copyright= kn-copyright= en-aut-name=AbeYuko en-aut-sei=Abe en-aut-mei=Yuko

kn-abstract=The prevalence of preoperative deep vein thrombosis (DVT) has been reported to be relatively high in patients undergoing total hip arthroplasty. We investigated the prevalence of DVT, the association between hip function and preoperative DVT, and the effect of a history of surgery in patients who underwent primary total hip arthroplasty. We retrospectively analyzed the cases of the patients who underwent primary total hip arthroplasty between April 2013 and February 2020 at our institution. We evaluated the prevalence of preoperative DVT based on the results of the patients’ ultrasound screening. We performed univariate and multivariate analyses to investigate the association between the incidence of DVT and patient factors including age, sex, hip function, medical histories, and American Society of Anesthesiologists Physical Status classification. We analyzed 451 patients (494 hips). The prevalence of DVT was 14.2% (64 patients). The multivariate analysis demonstrated that increased age was an independent significant risk factor for DVT. The prevalence of preoperative DVT was relatively high among patients who underwent primary total hip arthroplasty. Preoperative DVT tended to be more prevalent in older patients. Hip function was not associated with the incidence of DVT. en-copyright= kn-copyright= en-aut-name=OkutaniYuki en-aut-sei=Okutani en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujitaHiroshi en-aut-sei=Fujita en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaradaHideto en-aut-sei=Harada en-aut-mei=Hideto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KataokaMasanao en-aut-sei=Kataoka en-aut-mei=Masanao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurotaniYoshiki en-aut-sei=Murotani en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShimizuYu en-aut-sei=Shimizu en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Kyoto Katsura Hospital kn-affil= affil-num=2 en-affil=Center for Hip and Knee reconstruction, Rakuyo Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Kyoto Katsura Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Kyoto Katsura Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Faculty of Medicine, Kyoto University kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Kyoto City Hospital kn-affil= en-keyword=total hip arthroplasty kn-keyword=total hip arthroplasty en-keyword=deep vein thrombosis kn-keyword=deep vein thrombosis en-keyword=hip function kn-keyword=hip function en-keyword=ultrasound screening kn-keyword=ultrasound screening END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=5 article-no= start-page=541 end-page=545 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relationship between Wearing a Lead Apron and Work-related Musculoskeletal Disorders: A Questionnaire Survey of Japanese Radiological Technologists en-subtitle= kn-subtitle= en-abstract= kn-abstract=The purpose of this study was to conduct a self-reported questionnaire survey of work-related musculoskeletal disorders (WMSDs) among Japanese radiological technologists (RTs) and to report on the relationship between wearing a lead apron and WMSDs. Between February and April of 2021, RTs in Okayama Prefecture, Japan, were surveyed by mail and through a website. Information on individual characteristics, physical factors at work, and the presence of WMSDs were collected. All participants were also asked whether they frequently wore lead aprons. A multiple logistic regression analysis was used to assess the relationship between wearing a lead apron and WMSDs. The model was adjusted for age, sex, body mass index (BMI), and working hours. Of the 123 participants, 67 (54.5%) had WMSDs. Multiple logistic regression analysis revealed that WMSDs were significantly associated with wearing a lead apron. Compared to the “Never wear” group, the odds ratios for the “Always/Frequently wear” and “Sometimes/Rarely wear” groups were 7.87 (95% confidence interval [CI]=1.28-48.46; p=0.026) and 7.80 (95% CI=1.43-42.44; p=0.017), respectively. Our analysis suggests that wearing a lead apron is associated with WMSDs, and thus design modifications in lead aprons may improve the occupational health management of RTs. en-copyright= kn-copyright= en-aut-name=AkebiToru en-aut-sei=Akebi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsugakiRyutaro en-aut-sei=Matsugaki en-aut-mei=Ryutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OnoToshiro en-aut-sei=Ono en-aut-mei=Toshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Physical Therapy, Faculty of Health Sciences, Okayama Healthcare Professional University kn-affil= affil-num=2 en-affil=Department of Preventive Medicine and Community Health, School of Medicine, University of Occupational and Environmental Health kn-affil= affil-num=3 en-affil=Department of Physical Therapy, Faculty of Health Sciences, Okayama Healthcare Professional University kn-affil= en-keyword=work-related musculoskeletal disorders kn-keyword=work-related musculoskeletal disorders en-keyword=radiological technologists kn-keyword=radiological technologists en-keyword=lead apron kn-keyword=lead apron en-keyword=questionnaire survey kn-keyword=questionnaire survey en-keyword=multiple logistic regression analysis kn-keyword=multiple logistic regression analysis END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=3 article-no= start-page=333 end-page=338 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Successful Treatment of Atypical Femoral Fracture with Bowed Femur Using Contralateral Intramedullary Nail Combined with Early Daily Teriparatide en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a case of atypical femoral fracture achieving early fracture union with combination therapy comprising contralateral nail and immediate teriparatide injection.

We here investigated plasma clozapine levels before and after smoking cessation in Japanese inpatients with schizophrenia. We conducted a retrospective chart review of 14 inpatients with schizophrenia who were being treated with clozapine between June 1, 2019, and July 31, 2019 and who were smokers as of July 1, 2019, the day on which a smoking ban was instituted in the tertiary public psychiatric hospital. The primary outcome was individual differences in plasma clozapine levels between before and after the smoking ban, which were compared using paired t-tests. The mean plasma clozapine level was significantly increased, by 213.4 ng/mL (95% CI 119.9-306.8; p<0.01) or 53.2%. Four of the 14 inpatients experienced clinically significant side effects, such as myoclonus, drooling, and amnesia, due to the development of high plasma clozapine levels. Our findings indicated that close monitoring of plasma clozapine levels before and after smoking cessation and prior dose adjustment of clozapine may be necessary, to prevent a significant risk of developing high plasma clozapine levels, even in Japanese patients. en-copyright= kn-copyright= en-aut-name=TsukaharaMasaru en-aut-sei=Tsukahara en-aut-mei=Masaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SoRyuhei en-aut-sei=So en-aut-mei=Ryuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YadaYuji en-aut-sei=Yada en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KodamaMasafumi en-aut-sei=Kodama en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KishiYoshiki en-aut-sei=Kishi en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamadaNorihito en-aut-sei=Yamada en-aut-mei=Norihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Psychiatry, Okayama Psychiatric Medical Center kn-affil= affil-num=2 en-affil=Department of Psychiatry, Okayama Psychiatric Medical Center kn-affil= affil-num=3 en-affil=Department of Psychiatry, Okayama Psychiatric Medical Center kn-affil= affil-num=4 en-affil=Department of Psychiatry, Okayama Psychiatric Medical Center kn-affil= affil-num=5 en-affil=Department of Psychiatry, Okayama Psychiatric Medical Center kn-affil= affil-num=6 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Asian kn-keyword=Asian en-keyword=clozapine kn-keyword=clozapine en-keyword=schizophrenia kn-keyword=schizophrenia en-keyword=smoking kn-keyword=smoking END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=1 article-no= start-page=63 end-page=70 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Chidamide and Decitabine in Combination with a HAG Priming Regimen for Acute Myeloid Leukemia with TP53 Mutation en-subtitle= kn-subtitle= en-abstract= kn-abstract=We analyzed the treatment effects of chidamide and decitabine in combination with a HAG (homoharringtonine, cytarabine, G-CSF) priming regimen (CDHAG) in acute myeloid leukemia (AML) patients with TP53 mutation. Seven TP53 mutated AML patients were treated with CDHAG. The treatment effects were assessed using hemogram detection and bone marrow aspirate. The possible side effects were evaluated based on both hematological and non-hematological toxicity. Four of the seven patients were classified as having achieved complete remission after CDHAG treatment; one patient was considered to have achieved partial remission, and the remaining two patients were considered in non-remission. The overall response rate (ORR) to CDHAG was 71.4%. Regarding the side effects, the hematological toxicity level of the seven patients ranged from level III to level IV, and infections that occurred at lung, blood, and skin were recorded. Nausea, vomiting, liver injury, and kidney injury were also detected. However, all side effects were attenuated by proper management. The CDHAG regimen clearly improved the ORR (71.4%) of TP53-mutated AML patients, with no severe side effects. en-copyright= kn-copyright= en-aut-name=ZhangBei en-aut-sei=Zhang en-aut-mei=Bei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PeiZhixin en-aut-sei=Pei en-aut-mei=Zhixin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WangHongxia en-aut-sei=Wang en-aut-mei=Hongxia kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WuHuimin en-aut-sei=Wu en-aut-mei=Huimin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WangJunjie en-aut-sei=Wang en-aut-mei=Junjie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=BaiJunjun en-aut-sei=Bai en-aut-mei=Junjun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SongQinglin en-aut-sei=Song en-aut-mei=Qinglin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Hematology, Jiaozuo People’s Hospital kn-affil= affil-num=2 en-affil=Department of Hematology, Jiaozuo People’s Hospital kn-affil= affil-num=3 en-affil=Department of Hematology, Jiaozuo People’s Hospital kn-affil= affil-num=4 en-affil=Department of Hematology, Jiaozuo People’s Hospital kn-affil= affil-num=5 en-affil=Department of Hematology, Jiaozuo People’s Hospital kn-affil= affil-num=6 en-affil=Department of Hematology, Jiaozuo People’s Hospital kn-affil= affil-num=7 en-affil=Department of Hematology, Jiaozuo People’s Hospital kn-affil= en-keyword=acute myeloid leukemia kn-keyword=acute myeloid leukemia en-keyword=chidamide kn-keyword=chidamide en-keyword=decitabine kn-keyword=decitabine en-keyword=HAG kn-keyword=HAG en-keyword=TP53 mutation kn-keyword=TP53 mutation END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=6 article-no= start-page=725 end-page=734 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Morphological Changes and Durability of Skin and Mucosal Flaps in Intraoral and Pharyngeal Reconstructions: Long-term Follow-up and Literature Review for Potential Second Carcinomas en-subtitle= kn-subtitle= en-abstract= kn-abstract=The long-term changes in tissues implanted in the oral cavity and pharynx after head and neck reconstruction have not been fully evaluated. This study aimed to clarify the morphological changes, long-term durability, and potential for secondary carcinogenesis in such tissues. In our single-center study, the rough morphological changes in 54 cases of intraoral and pharyngeal skin and mucosal flaps were evaluated more than 10 years after flap transfer. In addition, the literature on the development of second carcinomas from skin flaps was reviewed. The mean follow-up period for transferred flaps was 148 months. The reconstruction areas and the probability of morphological changes were significantly correlated (p=0.006), especially in cases with tongue, lower gingiva, and buccal mucosal reconstruction. Free jejunal flap surfaces were well maintained, whereas tubed skin flaps showed severe morphological changes in cases with pharyngeal reconstruction. None of the flaps in our series developed second primary carcinomas. Skin flaps generally had good durability for > 10 years in intraoral environments, while mucosal flaps had better durability for pharyngeal reconstruction. Second squamous carcinomas arising from skin flaps are extremely rare; however, surgeons should take this possibility into consideration and conduct meticulous and long-term follow-up. en-copyright= kn-copyright= en-aut-name=MatsumotoHiroshi en-aut-sei=Matsumoto en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimataYoshihiro en-aut-sei=Kimata en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtaTomoyuki en-aut-sei=Ota en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SugiyamaNarushi en-aut-sei=Sugiyama en-aut-mei=Narushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OnodaSatoshi en-aut-sei=Onoda en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MakinoTakuma en-aut-sei=Makino en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakedaSeiko en-aut-sei=Takeda en-aut-mei=Seiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MizukawaNobuyoshi en-aut-sei=Mizukawa en-aut-mei=Nobuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Plastic and Reconstructive Surgery, Japanese Red Cross Okayama Hospital kn-affil= affil-num=5 en-affil=Department of Plastic and Reconstructive Surgery, Kagawa Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Okayama University Hospital kn-affil= en-keyword=skin flap kn-keyword=skin flap en-keyword=mucosal flap kn-keyword=mucosal flap en-keyword=oral reconstruction kn-keyword=oral reconstruction en-keyword=morphological change kn-keyword=morphological change en-keyword=second primary carcinoma kn-keyword=second primary carcinoma END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=5 article-no= start-page=575 end-page=583 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202110 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Accuracy of Acetabular Cup Implantation, as a Function of Body Mass Index and Soft-tissue Thickness, with a Mechanical Intraoperative Support Device: A Retrospective Observational Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=HipCOMPASS, a mechanical intraoperative support device used in total hip arthroplasty (THA), improves the cup-alignment accuracy. However, the alignment accuracy achieved by HipCOMPASS has not been specifically examined in obese patients. In this study, we retrospectively evaluated the relation between alignment accuracy and several obesity-related parameters in 448 consecutive patients who underwent primary THA using HipCOMPASS. We used computed tomography (CT) to measure the preoperative soft-tissue thickness of the anterior-superior iliac spine (ASIS) and pubic symphysis and the differences between preoperative and postoperative cup angle based on the cup-alignment error. We found significant correlations between the absolute value of radiographic anteversion difference and body mass index (r = 0.205), ASIS thickness (r = 0.419), and pubic symphysis thickness (r = 0.434). The absolute value of radiographic inclination difference was significantly correlated with ASIS (r = 0.257) and pubic symphysis thickness (r = 0.202). The receiver operating characteristic curve showed a pubic symphysis thickness of 37.2 mm for a ≥ 5° implantation error in both radiographic inclination and anteversion simultaneously. The cup-alignment error for HipCOMPASS was large in patients whose pubic symphysis thickness was ≥ 37.2 mm on preoperative CT. Our results indicate that methods other than HipCOMPASS, including computed tomography-based navigation systems, might be preferable in obese patients. en-copyright= kn-copyright= en-aut-name=SuzukiHayato en-aut-sei=Suzuki en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImaiNorio en-aut-sei=Imai en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HiranoYuki en-aut-sei=Hirano en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EndoNaoto en-aut-sei=Endo en-aut-mei=Naoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=2 en-affil=Division of Comprehensive Musculoskeletal Medcine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=3 en-affil=Division of Orthopedic Surgery, Department of Regenerative and Transplant Medicine, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=4 en-affil=Division of Orthopedic Surgery, Niigata Prefectural Tsubame Rosai Hospital kn-affil= en-keyword=HipCOMPASS kn-keyword=HipCOMPASS en-keyword=total hip arthroplasty kn-keyword=total hip arthroplasty en-keyword=cup-alignment accuracy kn-keyword=cup-alignment accuracy en-keyword=body mass index kn-keyword=body mass index en-keyword=soft-tissue thickness kn-keyword=soft-tissue thickness END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=1 article-no= start-page=71 end-page=77 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202102 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Thickness of the Medial Wall of the Acetabulum Prevents Acetabular Fracture during the Insertion of a Cementless Cup in Total Hip Arthroplasty: A Biomechanical Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Intra-operative acetabular fracture is a total hip arthroplasty complication that can occur during cementless cup insertion, especially in osteoporotic patients. We conducted this biomechanical study to investigate the impact resistance of the acetabulum with simulated bones of different density by drop-weight impact testing. Low- and high-density polyurethane foam blocks were used as osteoporotic and healthy bone models, respectively. Polyurethane blocks were used as the acetabular cancellous bone. Composite sheets were used as the acetabu-lum’s medial cortex. The testing revealed that the osteoporotic bone model’s impact resistance was significantly lower than that the healthy bone model’. In the healthy bone model, even thin acetabular cancellous bone with ≥ 1 mm acetabulum medial cortex was less likely to fracture. In the osteoporotic bone model, fracture was pos-sible without ≥ 1 mm medial cortex of the acetabulum and thick acetabular cancellous bone. Although impac-tion resistance differs due to bone quality, the impaction resistance in this osteoporotic bone model was equiv-alent to that healthy bone model’s when a thick medial wall was present. To avoid intra-operative acetabulum fracture, surgeons should consider both the bone quality and the thicknesses of the medial cortex and acetabu-lar cancellous bone. en-copyright= kn-copyright= en-aut-name=SankiTomoaki en-aut-sei=Sanki en-aut-mei=Tomoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TetsunagaTomonori en-aut-sei=Tetsunaga en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FurumatsuTakayuki en-aut-sei=Furumatsu en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamadaKazuki en-aut-sei=Yamada en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawamuraYoshi en-aut-sei=Kawamura en-aut-mei=Yoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=intra-operative acetabular fracture kn-keyword=intra-operative acetabular fracture en-keyword=drop weight impact testing kn-keyword=drop weight impact testing en-keyword=total hip arthroplasty kn-keyword=total hip arthroplasty en-keyword=impact resistance kn-keyword=impact resistance END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=5 article-no= start-page=371 end-page=379 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202010 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Anaplastic Lymphoma Kinase Fusion: A Review of Therapeutic Drugs and Treatment Strategies en-subtitle= kn-subtitle= en-abstract= kn-abstract=The prognosis of advanced non-small cell lung cancer (NSCLC) patients has improved in recent decades, especially for patients with an oncogenic driver mutation. Anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitors (TKIs) are effective for patients with the echinoderm microtubule-associated protein-like 4-ALK fusion gene. Several ALK-TKIs have been established: the first-generation ALK-TKI, crizotinib; second-generation ALK-TKIs, alectinib and ceritinib; and third-generation ALK-TKI, lorlatinib. Some ALK-TKIs are effective for tumors that are resistant to other ALK-TKIs; however, as is known in epidermal growth factor receptormutant lung cancer, tumor resistance is inevitable. ALK-positive NSCLCs acquire resistance via various mechanisms, making it a heterogeneous disease. Therefore, it is necessary to develop next-generation treatment strategies, such as the use of next-generation ALK-TKIs for secondary mutations, or combination therapies with ALK-TKIs and other TKIs. In this review, we summarize the development and use of ALK-TKIs, prior pivotal clinical trials, and resistance mechanisms. en-copyright= kn-copyright= en-aut-name=MakimotoGo en-aut-sei=Makimoto en-aut-mei=Go kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhashiKadoaki en-aut-sei=Ohashi en-aut-mei=Kadoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KiuraKatsuyuki en-aut-sei=Kiura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Respiratory Medicine, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=2 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= en-keyword=lung cancer kn-keyword=lung cancer en-keyword=anaplastic lymphoma kinase kn-keyword=anaplastic lymphoma kinase en-keyword=tyrosine kinase inhibitors kn-keyword=tyrosine kinase inhibitors en-keyword=resistance mechanism kn-keyword=resistance mechanism END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=3 article-no= start-page=185 end-page=190 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202006 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Stem Cell Therapy in Heart Disease: Limitations and Future Possibilities en-subtitle= kn-subtitle= en-abstract= kn-abstract=Heart diseases are one of the major causes of morbidity and mortality worldwide. Despite major advances in drug and interventional therapies, surgical procedures, and organ transplantation, further research into new therapeutic options is still necessary. Stem cell therapy has emerged as one option for the treatment of a variety of heart diseases. Although a large number of clinical trials have shown stem cell therapy to be a promising therapeutic approach, the results obtained from these clinical studies are inconsistent, and stem cell-based improvements of heart performance and cardiac remodeling were found to be quite limited. Since the precise mechanisms underlying the therapeutic actions of stem cells are still under debate, researchers have developed a variety of strategies to improve and boost the potency of stem cells in repair. In this review, we summarize both the current therapeutic strategies using stem cells and future directions for enhancing stem cell potency. en-copyright= kn-copyright= en-aut-name=SanoToshikazu en-aut-sei=Sano en-aut-mei=Toshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshigamiShuta en-aut-sei=Ishigami en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ItoTatsuo en-aut-sei=Ito en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SanoShunji en-aut-sei=Sano en-aut-mei=Shunji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Surgery, Division of Pediatric Cardiothoracic Surgery, University of California San Francisco kn-affil= affil-num=2 en-affil=Department of Surgery, Division of Pediatric Cardiothoracic Surgery, University of California San Francisco kn-affil= affil-num=3 en-affil=Department of Hygiene, Kawasaki Medical University kn-affil= affil-num=4 en-affil=Department of Surgery, Division of Pediatric Cardiothoracic Surgery, University of California San Francisco kn-affil= en-keyword=heart disease kn-keyword=heart disease en-keyword=stem cell kn-keyword=stem cell en-keyword=myocardial regeneration kn-keyword=myocardial regeneration END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=2 article-no= start-page=151 end-page=157 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202004 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Non-traumatic Atypical Peri-implant Femoral Fracture at the Distal Screw after Short Femoral Nail Fixation for a Pertrochanteric Fracture en-subtitle= kn-subtitle= en-abstract= kn-abstract= This is the second report of an atypical peri-implant femoral fracture occurring at the distal screw after intramedullary nail fixation of a pertrochanteric fracture. A 94-year-old Japanese female with a 5-year history of alendronate intake presented with prodromal pain in her right thigh after intramedullary nail fixation. Plain radiographs showed an incomplete noncomminuted transverse fracture at the distal screw, suggesting an atypical peri-implant femoral fracture. The pathogenesis of an atypical peri-implant femoral fracture could be a combined systemic bone metabolism disorder and repetitive overloading at the screw, similar to the pathogenesis of an atypical periprosthetic femoral fracture around stem implantation. en-copyright= kn-copyright= en-aut-name=YamamotoNorio en-aut-sei=Yamamoto en-aut-mei=Norio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Dan’uraTomoyuki en-aut-sei=Dan’ura en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NodaTomoyuki en-aut-sei=Noda en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Unnan City Hospital kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Unnan City Hospital kn-affil= affil-num=3 en-affil=Department of Musculoskeletal Traumatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=atypical femoral fracture kn-keyword=atypical femoral fracture en-keyword=insufficiency fracture kn-keyword=insufficiency fracture en-keyword=bisphosphonate kn-keyword=bisphosphonate en-keyword=atypical peri-implant femoral fracture, kn-keyword=atypical peri-implant femoral fracture, en-keyword=atypical periprosthetic femoral fracture kn-keyword=atypical periprosthetic femoral fracture END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=2 article-no= start-page=145 end-page=150 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202004 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Efficacy of Mirabegron for the Relief of Ureteral Stent-Related Symptoms en-subtitle= kn-subtitle= en-abstract= kn-abstract= To investigate the efficacy of mirabegron for lower urinary tract symptoms in patients with an indwelling ureteral stent after ureterorenoscopic lithotripsy. This was a prospective follow-up study of 76 patients with stent-related symptoms (SRSs). Patients with upper urinary calculi who were pre-stented for > 2 weeks before lithotripsy were examined for the presence of SRSs by tests including the International Prostate Symptom Score (IPSS), OAB Symptom Score (OABSS), and urinary bother and pain measured by a Visual Analogue Scale (VAS) before lithotripsy. Mirabegron (50 mg/day) was prescribed post-lithotripsy for 2 weeks. SRSs were assessed at the time of stent removal. The IPSS scores improved significantly from 16.2 to 14.3 (p<0.001) and the IPSS-QoL scores decreased significantly from 5.0 to 4.6 (p=0.012). The OABSS scores improved significantly from 7.7 to 6.8 (p=0.006), and the urinary urgency scores (OABSS-Q3) decreased significantly from 3.24 to 2.68 (p<0.001).

Mirabegron significantly improved SRSs and the number of nocturia episodes due to a ureteral stent. en-copyright= kn-copyright= en-aut-name=OtsukiHideo en-aut-sei=Otsuki en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamasakiTomoya en-aut-sei=Yamasaki en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HoriShunsuke en-aut-sei=Hori en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AokiHiroshi en-aut-sei=Aoki en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KosakaTakeo en-aut-sei=Kosaka en-aut-mei=Takeo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UeharaShinya en-aut-sei=Uehara en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujioKei en-aut-sei=Fujio en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Urology, Abiko Toho Hospital kn-affil= affil-num=2 en-affil=Department of Urology, Abiko Toho Hospital kn-affil= affil-num=3 en-affil=Department of Urology, Abiko Toho Hospital kn-affil= affil-num=4 en-affil=Department of Urology, Abiko Toho Hospital kn-affil= affil-num=5 en-affil=Department of Urology, Keio University kn-affil= affil-num=6 en-affil=Department of Urology, Kawasaki Medical School General Medical Center kn-affil= affil-num=7 en-affil=Department of Urology, Abiko Toho Hospital kn-affil= en-keyword=stent-related symptoms kn-keyword=stent-related symptoms en-keyword=overactive bladder kn-keyword=overactive bladder en-keyword=mirabegron kn-keyword=mirabegron en-keyword=ureterorenoscopic lithotripsy kn-keyword=ureterorenoscopic lithotripsy en-keyword=ureteral stent kn-keyword=ureteral stent END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=2 article-no= start-page=123 end-page=128 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202004 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Diagnostic Capacity of Pre-treatment 18F-FDG PET/CT for Predicting the Extranodular Spread of Lymph Node Metastases in Patients with Oral Squamous Cell Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract= The aim of this study was to evaluate the ability of pretreatment 90-min 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) to predict the extranodular spread of lymph node metastases in oral squamous cell carcinoma. We retrospectively reviewed the cases of 56 patients who underwent pretreatment 18F-FDG PET/CT and surgery with neck dissection. Maximum standardized uptake value, metabolic tumor volume, and total lesion glycolysis were measured for the 56 primary sites and maximum standardized uptake value was measured for 115 lymph node levels. Extranodular spread was present at 9 lymph node levels in 7 patients. Significant differences were found in metabolic tumor volume and total lesion glycolysis of the primary site, and in lymph node maximum standardized uptake value, between patients with and without extranodular spread (p<0.05). Combining primary site total lesion glycolysis and lymph node maximum standardized uptake volume at their respective optimal cutoffs, the sensitivity, specificity, and accuracy for predicting extranodular spread were 89%, 92%, and 92%, respectively. Pretreatment 18F-FDG PET/CT is useful for predicting extranodular spread in patients with oral squamous cell carcinoma. The combined use of primary site total lesion glycolysis and lymph node maximum standardized uptake value showed greater predictive value than either predictor singly. en-copyright= kn-copyright= en-aut-name=FukuharaRyuichiro en-aut-sei=Fukuhara en-aut-mei=Ryuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShinyaTakayoshi en-aut-sei=Shinya en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FukumaShogo en-aut-sei=Fukuma en-aut-mei=Shogo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OgawaNanako en-aut-sei=Ogawa en-aut-mei=Nanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasaokaYoshihisa en-aut-sei=Masaoka en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MarunakaHidenori en-aut-sei=Marunaka en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AriokaTadashi en-aut-sei=Arioka en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KajiMitsumasa en-aut-sei=Kaji en-aut-mei=Mitsumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KanazawaSusumu en-aut-sei=Kanazawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=6 en-affil=Department of Pathology, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=7 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=8 en-affil=Department of Radiology, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=9 en-affil=Department of Radiology, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=10 en-affil=Department of Radiology, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= affil-num=11 en-affil=Department of Radiology, Okayama Diagnostic Imaging Center, Okayama university Hospital kn-affil= en-keyword=18F-fluorodeoxyglucose positron emission tomography/computed tomography kn-keyword=18F-fluorodeoxyglucose positron emission tomography/computed tomography en-keyword=extranodular spread kn-keyword=extranodular spread en-keyword=metastasis kn-keyword=metastasis en-keyword=oral squamous cell carcinoma kn-keyword=oral squamous cell carcinoma END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=1 article-no= start-page=53 end-page=58 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202002 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Robotic Renal Autotransplantation: A Feasibility Study in a Porcine Model en-subtitle= kn-subtitle= en-abstract= kn-abstract= We investigated the feasibility of robotic renal autotransplantation (RAT) in a porcine model to reduce invasiveness of RAT. Five pigs underwent robotic RAT using the da Vinci® robotic system. A robotic left nephrectomy was performed in all cases. Robotic RAT was performed on the left side in all but one case. Four ports were used. In 3 cases, the kidney was taken out through the GelPort® and irrigated on ice with Ringer’s solution. In 2 cases, a complete intracorporeal robotic RAT was performed. An end-to-side anastomosis was performed between the renal vein and the external iliac vein and between the renal artery and the external iliac artery. Ureteroneocystostomy was also performed in 2 cases. All cases were performed robotically without open conversion. The median (IQR) console time was 3.1 (0.7) h, and the operative time was 3.8 (1.1) h. The estimated blood loss was 30 (0) ml. The warm ischemia time was 4.0 (0.2) min, and the cold ischemia time was 97 (17) min. Intracorporeal transarterial hypothermic renal perfusion was feasible in the 2 complete intracorporeal robotic RAT cases by using a perfusion catheter through a laparoscopic port. Robotic RAT has the potential to be a new minimally invasive substitute for conventional open surgery. en-copyright= kn-copyright= en-aut-name=KubotaRisa en-aut-sei=Kubota en-aut-mei=Risa kn-aut-name=

body and is necessary for a multitude of crucial processes in life. However, iron overload is known to induce carcinogenesis via oxidative stress. Cancer cells require large amounts of iron for their rapid division and cell growth. Iron was recently found to play a role in cancer stem cells (CSCs); it maintains stemness during development. Iron also plays an important role in stemness by moderating reactive oxygen species. Thus, iron metabolism in CSCs is a promising therapeutic target. In this review, we summarize the roles of iron in cancer cells and CSCs. We also summarize anti-cancer therapeutic studies with iron chelators and describe our expectation of a new therapeutic strategy for CSCs on the basis of our findings. en-copyright= kn-copyright= en-aut-name=ChenYuehua en-aut-sei=Chen en-aut-mei=Yuehua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=XingBoyi en-aut-sei=Xing en-aut-mei=Boyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=QiJiping en-aut-sei=Qi en-aut-mei=Jiping kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Pathology and Experimental Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pathology and Experimental Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pathology and Experimental Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathology, the First Affiliated Hospital of Harbin Medical University kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pathology and Experimental Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=cancer stem cell kn-keyword=cancer stem cell en-keyword=stemness kn-keyword=stemness en-keyword=iron kn-keyword=iron en-keyword=chelation kn-keyword=chelation en-keyword=chemotherapy kn-keyword=chemotherapy END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=5 article-no= start-page=457 end-page=461 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201910 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Granulation Polyp in the Colon Masquerading as Metastatic Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract= A 60-year-old Caucasian male was diagnosed with lung adenocarcinoma and multiple metastases to the bone, spleen, and brain. He underwent radiotherapy for the brain and lumbar spine metastases, plus chemotherapy (cisplatin and pemetrexed). The chemotherapy was discontinued due to vomiting and hyponatremia, and nivolumab was then administered. Eight months later, 18F-fluorodeoxyglucose positron emission tomography showed tracer uptake in the colon. Colonoscopy revealed a reddish multinodular polyp in the sigmoid colon. The polyp showed irregular microvessels. No colonic mucosal surface structures were observed. Colonic metastasis of the lung carcinoma was highly suspected; the polyp was therefore surgically removed. The histological analysis revealed granulation tissue and suppurative inflammation without neoplastic changes. We diagnosed the lesion as a granulation polyp. Despite the difficulty in diagnosing these lesions due to their rarity and similarity to metastatic colon tumors, we suggest that recognizing the endoscopic features of the polyp surface may allow a preoperative diagnosis. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakaharaMasahiro en-aut-sei=Takahara en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamazakiTatsuhiro en-aut-sei=Yamazaki en-aut-mei=Tatsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KondoYoshitaka en-aut-sei=Kondo en-aut-mei=Yoshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=colonoscopy kn-keyword=colonoscopy en-keyword=colonic neoplasms kn-keyword=colonic neoplasms en-keyword=granulation polyp kn-keyword=granulation polyp END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=5 article-no= start-page=387 end-page=392 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201910 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison of Two Different Drugs for Overactive Bladder, Solifenacin and Mirabegron: A Prospective Randomized Crossover Study en-subtitle= kn-subtitle= en-abstract= kn-abstract= To assess the efficacy and safety of 2 drugs for overactive bladder (OAB), solifenacin and mirabegron. Fortyseven female OAB patients were randomized into 2 groups. Twenty-three patients were initially prescribed solifenacin for 4 weeks, followed by mirabegron for 4 weeks (group S). The other 24 patients were initially prescribed mirabegron for 4 weeks, followed by solifenacin for 4 weeks (group M). Evaluations included clinical determination of the OAB symptom score (OABSS), International Prostate Symptom Score (IPSS), and Visual Analog Scale. The IPSS significantly improved after the administration of solifenacin in both groups. The OABSS significantly improved in both groups after 4 weeks. In group M, the OABSS after eight weeks was significantly improved compared to that after 4 weeks. However, in group S, it was not significantly improved. Twelve patients experienced adverse events during the solifenacin treatment, while 2 patients experienced adverse events during the mirabegron treatment. Both solifenacin and mirabegron led to improved OAB symptoms. Switching from mirabegron to solifenacin significantly improved the OABSS. However, mirabegron led to fewer adverse events than solifenacin. We recommend that mirabegron be prescribed first for OAB patients. If patients are not satisfied with mirabegron, solifenacin should be used. en-copyright= kn-copyright= en-aut-name=InoueMiyabi en-aut-sei=Inoue en-aut-mei=Miyabi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YokoyamaTeruhiko en-aut-sei=Yokoyama en-aut-mei=Teruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Miyabi Urogyne Clinic kn-affil= affil-num=2 en-affil=Yokoyama Urological Clinic kn-affil= en-keyword=overactive bladder, kn-keyword=overactive bladder, en-keyword=randomized crossover study kn-keyword=randomized crossover study en-keyword=solifenacin kn-keyword=solifenacin en-keyword=mirabegron kn-keyword=mirabegron END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=4 article-no= start-page=285 end-page=297 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201908 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dynamic Reorganization of Microtubule and Glioma Invasion en-subtitle= kn-subtitle= en-abstract= kn-abstract= Gliomas are characterized as highly diffuse infiltrating tumors, and currently available treatments such as surgery, radiation and chemotherapy are unfeasible or show limited efficacy against these tumors. Recent genetic and epigenetic analyses of glioma have revealed increasing evidence of the role of driver genetic alterations in glioma development and led to the identification of prognostic factors. Despite these findings, the survival rates of glioma patients remain low, and alternative treatments and novel targets are needed. Recent studies identified neural stem cells as the possible origin of gliomas, and some evidence has revealed shared functions and mechanisms between glioma cells and neurons, also supporting their similarity. The cytoskeleton plays important roles in the migration of normal cells as well as cancer cells. Recent reports have described a role for microtubules, a component of the cytoskeleton, in glioma invasion. Notably, several factors that regulate microtubule functions, such as microtubule-associated proteins, plus-end tracking proteins, or motor proteins, are upregulated in glioma tissues compared with normal tissue, and upregulation of these factors is associated with high invasiveness of glioma cells. In this review, we describe the mechanism of microtubules in glioma invasion and discuss the possibility of microtubule-targeted therapy to inhibit glioma invasion. en-copyright= kn-copyright= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchikawaTomotsugu en-aut-sei=Ichikawa en-aut-mei=Tomotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Neurosurgery, The University of Texas Health Science Center at Houston kn-affil= affil-num=2 en-affil=Department of Neurosurgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=glioma kn-keyword=glioma en-keyword=cytoskeletons kn-keyword=cytoskeletons en-keyword=invasion kn-keyword=invasion en-keyword=microtubules kn-keyword=microtubules END start-ver=1.4 cd-journal=joma no-vol=126 cd-vols= no-issue=3 article-no= start-page=203 end-page=208 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Modulation of neuronal function and neuroprotection by astrocytes kn-title=アストロサイトによる神経機能修飾とパーキンソン病での神経保護 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=AsanumaMasato en-aut-sei=Asanuma en-aut-mei=Masato kn-aut-name=浅沼幹人 kn-aut-sei=浅沼 kn-aut-mei=幹人 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　神経ゲノム学 en-keyword=アストロサイト kn-keyword=アストロサイト en-keyword=抗酸化防御機構 kn-keyword=抗酸化防御機構 en-keyword=パーキンソン病 kn-keyword=パーキンソン病 en-keyword=メタロチオネイン kn-keyword=メタロチオネイン en-keyword=Nrf2 kn-keyword=Nrf2 END start-ver=1.4 cd-journal=joma no-vol=124 cd-vols= no-issue=2 article-no= start-page=129 end-page=136 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20120801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Antibacterial efficacy of photocatalytic reaction on titanium dioxide-coated ceramic air filters kn-title=酸化チタン担持セラミックフィルターの光触媒反応による抗菌効果の検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Titanium dioxide (TiO2) photocatalysis generates reactive oxygen species such as ・OH and ・O2-, which can effectively eliminate organic compounds. In the present study, we evaluated the antibacterial and antifungal effects of TiO2-coated ceramic air filters in both laboratory and hospital settings. Photocatalysis with the TiO2-coated ceramic filter effectively inactivated all 4 pathogenic organisms tested. Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans. After the photocatalysis reaction for 4 h under UV-A (365nm, 250μW/㎠) irradiation, the percentage reductions of the number of E. coli, P. aeruginosa, S. aureus, C. albicans cells were 99.9%, 98.9%, 97.7% and 99.9%, respectively, indicating that Gram-negative bacteria are more susceptible to such photocatalysis than Gram-positive bacteria. Scanning electron microscopic analysis showed damage to the cytoplasmic membrane and cell wall by photocatalysis : consistent with above observations, the morphological change of Gram-negative E. coli was greater than that of Gram-positive S. aureus. 　Further, an air cleaner equipped with a TiO2-coated ceramic filter significantly decreased the number of bacteria floating in hospitals. 　These results indicate that air cleaners with TiO2-coated ceramic filters could be useful in reducing the incidence of nosocomial infections. en-copyright= kn-copyright= en-aut-name=NakaoMiyuki en-aut-sei=Nakao en-aut-mei=Miyuki kn-aut-name=中尾美幸 kn-aut-sei=中尾 kn-aut-mei=美幸 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　病原細菌学 en-keyword=光触媒（photocatalysis） kn-keyword=光触媒（photocatalysis） en-keyword=酸化チタン担持セラミックフィルター（TiO2-coated ceramic air filters） kn-keyword=酸化チタン担持セラミックフィルター（TiO2-coated ceramic air filters） en-keyword=抗菌効果（antimicrobial effect） kn-keyword=抗菌効果（antimicrobial effect） en-keyword=院内感染（nosocomial infection） kn-keyword=院内感染（nosocomial infection） en-keyword=空気清浄機（air cleaner） kn-keyword=空気清浄機（air cleaner） END start-ver=1.4 cd-journal=joma no-vol=123 cd-vols= no-issue=3 article-no= start-page=239 end-page=241 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20111201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Drug interaction (22. opioid-drug interactions) kn-title=薬物相互作用（22―オピオイドの薬物相互作用） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KawashimaRieko en-aut-sei=Kawashima en-aut-mei=Rieko kn-aut-name=川島理恵子 kn-aut-sei=川島 kn-aut-mei=理恵子 aut-affil-num=1 ORCID= en-aut-name=MatsunagaHisashi en-aut-sei=Matsunaga en-aut-mei=Hisashi kn-aut-name=松永尚 kn-aut-sei=松永 kn-aut-mei=尚 aut-affil-num=2 ORCID= en-aut-name=SendoToshiaki en-aut-sei=Sendo en-aut-mei=Toshiaki kn-aut-name=千堂年昭 kn-aut-sei=千堂 kn-aut-mei=年昭 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学病院　薬剤部 affil-num=2 en-affil= kn-affil=岡山大学病院　薬剤部 affil-num=3 en-affil= kn-affil=岡山大学病院　薬剤部 END start-ver=1.4 cd-journal=joma no-vol=122 cd-vols= no-issue=1 article-no= start-page=33 end-page=38 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=20100401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Contribution of cell cultures to the Nobel Prize kn-title=細胞培養のノーベル賞への貢献 en-subtitle= kn-subtitle= en-abstract= kn-abstract=約1世紀前に, 生きた組織や細胞を動物の体外に取り出した研究―組織培養あるいは細胞培養―が始まった．その後の研究の流れの中で, 1) 組織・細胞培養の特性を生かして行われた研究でノーベル賞に輝いた研究, 2) 組織・細胞培養の経験をもつノーベル賞受賞者, 3) ノーベル賞にはならなかったけれども特記できると私が考える細胞培養の研究，などについて取り上げてみたい. en-copyright= kn-copyright= en-aut-name=NambaMasayoshi en-aut-sei=Namba en-aut-mei=Masayoshi kn-aut-name=難波正義 kn-aut-sei=難波 kn-aut-mei=正義 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=新見公立大学 en-keyword=細胞 kn-keyword=細胞 en-keyword=培養 kn-keyword=培養 en-keyword=ノーベル賞 kn-keyword=ノーベル賞 END start-ver=1.4 cd-journal=joma no-vol=121 cd-vols= no-issue=3 article-no= start-page=143 end-page=147 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=DNA topoisomerase Ⅱβ activates a subset of neuronal genes kn-title=DNAトポイソメラーゼⅡβによる神経関連遺伝子の活性化機構 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=SanoKuniaki en-aut-sei=Sano en-aut-mei=Kuniaki kn-aut-name=佐野訓明 kn-aut-sei=佐野 kn-aut-mei=訓明 aut-affil-num=1 ORCID= en-aut-name=MiyajiMary en-aut-sei=Miyaji en-aut-mei=Mary kn-aut-name=宮地まり kn-aut-sei=宮地 kn-aut-mei=まり aut-affil-num=2 ORCID= en-aut-name=TsutsuiM.

Both of a proper concentration of potassium permanganate solution and 6.0 % sulfuric acid solution containing 0.1 % silver nitrate are individually pumped up with respective flow rates of 0.51 ml min(-l) and merged into a carrier stream. A 20 μ1 of sample solution is injected into the flow of sulfuric acid solution at just before the merging place. The sample mixed with the carrier solutions in a reaction manifol(polytetrafluoroethylene tubing: 0.5 mm i.d. x 30 m), is passed through a thermostated bath at 100 °c and led to a flow cell for the absorbance measurements at 525 nm. The absorbances are continuously recorded with time. The peaks in the recordings showed good reproducibility and the calibration obtained at a linear concentration range of 0 - 170 mg 1(-1) COD with glucose as standard. The detection limit and precision confirmed with this method were 5 mg 1(-1) and 0.8 %, respectively. Chloride ion up to 200 mg 1(-1) did not interfere without elimination of a silver chloride precipitate. By the present FIA method, several industrial waste water samples were analyzed at a sampling rate of about 40 samples per hour, and their apparent COD values were compared with those found by the manual JIS method. Both of the methods gave the similar results within an error range from -35 to +5 %. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=KorenagaTakashi kn-aut-sei=Korenaga kn-aut-mei=Takashi aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=IkatsuHisayoshi kn-aut-sei=Ikatsu kn-aut-mei=Hisayoshi aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=MoriwakeTosio kn-aut-sei=Moriwake kn-aut-mei=Tosio aut-affil-num=3 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=TakahashiTeruo kn-aut-sei=Takahashi kn-aut-mei=Teruo aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Center for Environmetal Conservation Technology, Okayama University affil-num=2 en-affil= kn-affil=Center for Environmetal Conservation Technology, Okayama University affil-num=3 en-affil= kn-affil=Department of Synthetics Chemistry affil-num=4 en-affil= kn-affil=Department of Industrial Chemistry END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=1 article-no= start-page=39 end-page=47 dt-received= dt-revised= dt-accepted= dt-pub-year=1975 dt-pub=19750701 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=G.P.zones and Clusters in Al-Zn Alloy and Al-Cu Alloy en-subtitle= kn-subtitle= en-abstract= kn-abstract=As to Al-Zn alloy, the difference between the formation of G.P.zones and that of clusters was investigated by measurements of electrical resistivity. The results obtained were summarised as follows: (1) G.P.zones formed during the quench and quenched-in vacancies increase greatly as-quenched resistivity P(o) as quenching temperature Tq is raised, and clusters increase slightly P(o) as Tq is lowered. (2) For one Tq and one Ta, the time required to reach P(e)' for Al-1.3at % Zn alloy is longer than that for Al-3.0at % Zn alloy. This is due to the difference of number of zinc atom in the clusters. (3) For one Ta and one concentration of zinc, the time required to reach p'(e) at Tq = 170℃ is longer than that at Tq = 300℃. This is due to the difference in concentration of quenchedin vacancies. As to Al-Cu alloy, the solvus temperature for G.P.zones was determined from the existence of P(m) in ageing curves by measurements of electrical resistivity. Consequently the solvus temperature is between 20℃ and 60℃. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=OhtaMutsuo kn-aut-sei=Ohta kn-aut-mei=Mutsuo aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=HamamotoTakao kn-aut-sei=Hamamoto kn-aut-mei=Takao aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Department of Industrial Science affil-num=2 en-affil= kn-affil=Graduate school of Industrial Science END start-ver=1.4 cd-journal=joma no-vol=121 cd-vols= no-issue=2 article-no= start-page=85 end-page=90 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20090803 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=CRTH2 plays an essential role in the pathophysiology of Cry j 1 -induced pollinosis in mice kn-title=マウススギ花粉症モデルにおける CRTH2の役割 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=NomiyaRie en-aut-sei=Nomiya en-aut-mei=Rie kn-aut-name=野宮理恵 kn-aut-sei=野宮 kn-aut-mei=理恵 aut-affil-num=1 ORCID= en-aut-name=OkanoMitsuhiro en-aut-sei=Okano en-aut-mei=Mitsuhiro kn-aut-name=岡野光博 kn-aut-sei=岡野 kn-aut-mei=光博 aut-affil-num=2 ORCID= en-aut-name=FujiwaraTazuko en-aut-sei=Fujiwara en-aut-mei=Tazuko kn-aut-name=藤原田鶴子 kn-aut-sei=藤原 kn-aut-mei=田鶴子 aut-affil-num=3 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name=西﨑和則 kn-aut-sei=西﨑 kn-aut-mei=和則 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　耳鼻咽喉・頭頸部外科学 affil-num=2 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　耳鼻咽喉・頭頸部外科学 affil-num=3 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　耳鼻咽喉・頭頸部外科学 affil-num=4 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　耳鼻咽喉・頭頸部外科学 en-keyword=スギ花粉症 kn-keyword=スギ花粉症 en-keyword=モデルマウス kn-keyword=モデルマウス en-keyword=プロスタグランジンD(2) kn-keyword=プロスタグランジンD(2) en-keyword=CRTH(2) kn-keyword=CRTH(2) END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=5-6 article-no= start-page=483 end-page=494 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on clinical course and prognosis of chronic pancreatitis Part 3.

Pancreatic pseudocysts were found in 29 patient with CP, biliary stenosis in 20 patients, and a peptic ulcer in 26 patients. Determination of whether the abdominal pain is caused by acute exacerbation of CP or by the peptic ulcer is important, because abdominal pain due to peptic ulcer is easily relieved by administration of H2-receptor antagonist. Mild liver damage or chronic hepatitis was observed in 26 patients with CP ; and liver cirrhosis in nine. Duodenal stenosis was found in two patients. Thirty-nine patients with CP died during the follow-up period. Patients with alcoholic CP were significantly younger than those with nonalcoholic CP at the time of death. Thirteen patients died from malignancy which was the most frequent cause of deaths. Sudden deaths were observed in seven patients. Six patients died from pneumonia which was refractory to the intensive medical treatment. Three patients died from diabetic renal failure and three from heart failure. The observed number of CP was significantly higher than the expected number for the sex-age-matched general population in total deaths and cancer deaths. A similar finding was obtained in alcoholic CP. Alcoholic CP showed poorer prognosis than nonalcoholic CP. Contributing factors to the prognosis were age at the time of diagnosis, diabetes, smoking habit, outcome of pain, years at diagnosis in alcoholic CP, whereas they were age at diagnosis, smoking habit and diabetes in nonalcoholic CP. This indicates that abstinence, quitting smoking, and careful treatment for diabetes are important for improving the prognosis of CP. en-copyright= kn-copyright= en-aut-name=MiyakeHirofumi en-aut-sei=Miyake en-aut-mei=Hirofumi kn-aut-name=三宅啓文 kn-aut-sei=三宅 kn-aut-mei=啓文 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=慢性膵炎 kn-keyword=慢性膵炎 en-keyword=合併症 kn-keyword=合併症 en-keyword=予後 kn-keyword=予後 en-keyword=予後因子 kn-keyword=予後因子 END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=4 article-no= start-page=281 end-page=292 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Pharmacological specificity of antipsychotic, antiischemic and some other drugs for σ receptors labeled with [(3)H] haloperidol kn-title=ラット脳内 σ 受容体の薬理学的特異性に関する研究―とくに抗精神病薬との抗虚血剤の作用について― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pharmacological specificity of several classes of drugs such as antipsychotics and antiischemic agents was assessed for σ receptors labeled with [(3)H] haloperidol. Specific binding of [(3)H] haloperidol in the presence of 25 nM spiperone was saturable and high affinity )Kd=1.96±1.31 nM, Bmax=2.37±0.27pmol/mg of protein;n=8). Among the 29 antipsychotics tested in inhibition studies, bromperidol and haloperidol were the most potent inhibitors (Ki=0.9nM, 1.0nM, respectively). The conventional antipsychotics moperone, timiperone etc. and the novel promising drugs YM-09151, Y-516, BMY-14802 and remoxipride potently inhibited [(3)H] haloperidol binding with the Ki in the range of low to moderate nanomolar. On the other hand, among the other 27 drugs tested, the antispasmodics eperisone and tolperisone, the antiischemic agents ifenprodil, the Ca(2+) antagonist flunarizine and cinnarizine, and the antitussives carbetapentane, cloperastine and dextromethorphan, were especially potent inhibitors. These results, taken together with the evidence that the antiischemic agents ifenprodil and dextromethorphan antagozine NMDA responses and NMDA receptor complex is a possible site of action for neuroprotective agents, strongly suggest that σ receptors may be potential sites of action for antiischemic as well as antipsychotic drugs, i.e., σ receptors mediate the neuroprotective effects of certain antiischemic agents by affecting the NMDA receptor complex. en-copyright= kn-copyright= en-aut-name=ZushiYoshifumi en-aut-sei=Zushi en-aut-mei=Yoshifumi kn-aut-name=図子義文 kn-aut-sei=図子 kn-aut-mei=義文 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部神経精神医学教室 en-keyword=sigma receptors kn-keyword=sigma receptors en-keyword=antipsychotics kn-keyword=antipsychotics en-keyword=ifenprodil kn-keyword=ifenprodil en-keyword=dextromethorophan kn-keyword=dextromethorophan en-keyword=eperisone kn-keyword=eperisone END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=4 article-no= start-page=267 end-page=280 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Hemadosorption phenomenon in cultured cells caused by HSV-1 induced Fc receptor : ultrastructural and biological studies kn-title=単純ヘルペスウイルス感染細胞表面に発現するFc-レセプターによる感作赤血球吸着反応―微細形態学的ならびに細胞生物学的考察― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Adsorption of sensitized sheep erythrocytes to FL cells infected with HSV-1 was studied biologically and morphologically. Almost 100% of the FL cells at a late stage of infection (i.e. 23 hrs) were positive for the appearance of HSV-1 gC antigen, while about 86% of them had hemadsorption (HAD) activity. To elucidate why all the infected cells do not show HAD activity, FL cells at the similar stage of infection were examined by high-resolution scanning electron microscopy and also by immuno-scanning electron microscopy. When infected cells were treated first with peroxidase-antiperoxidase (PAP) rabbit IgG and then with goat anti-rabbit IgG Iabeled with colloidal gold, the surface of all the cells were clearly tagged with colloidal gold particles. Morphological observations of HAD revealed that many microvilli adhered to the surface of erythrocytes. Thus, in addition to the expression of HSV-induced FcR on the surface membrane of infected cells, which is prerequisite for HAD, microvilli play an essential role on the appearance of this phenomenon. en-copyright= kn-copyright= en-aut-name=BaiZeng-Liang en-aut-sei=Bai en-aut-mei=Zeng-Liang kn-aut-name=白増亮 kn-aut-sei=白 kn-aut-mei=増亮 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部ウイルス学教室 en-keyword=単純ヘルペスウイルス kn-keyword=単純ヘルペスウイルス en-keyword=Fc-レセプター kn-keyword=Fc-レセプター en-keyword=microvilli kn-keyword=microvilli en-keyword=hemadsorption kn-keyword=hemadsorption en-keyword=走査電子顕微鏡 kn-keyword=走査電子顕微鏡 END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=5-6 article-no= start-page=651 end-page=661 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Analysis of referrals from a clinic in a remoted area kn-title=地域診療所における患者紹介の分析 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To clarify the health needs in a community, three hundred and ten referrals from a public clinic in a typical Japanese rural area were reviewed concerning age, sex, medical facility to which the patient was referred, reason for referral, and disease from January 1, 1986 to December 31, 1990. The referral patients were classified into 4 groups by age ; 0-19, 20-49, 50-69, 70 years old and older. The number of referrals, admissions, operations, and emergency referrals were divided by the number of consultations to obtain the referral, admission, operation, and emergency referral rates, respectively. Haysshi's third method of quantifica-tion was used to analyze the characteristics of the referrals. The referral rates did not differ among the age groups except for the referral rate of men under 20. However, the admission rate increased with age. The operation rate at the age of 50 and older was higher than that of referrals under 50. The emergency referral rate at the age of 70 and older was higher than that of referrals under 70. All rates of adult men were higher than those of adult woman. Analysis by Hayashi's third method of quantification revealed that 4 major characteristics of referrals were "admission factor", "referral facility factor", "disease factor", and "referral reason factor". In conclusion, it is informative and useful for the primary care physician to analyze referral patients to determine the health needs in the community and the kind of primary care services that should be provided. en-copyright= kn-copyright= en-aut-name=HamadaHirohisa en-aut-sei=Hamada en-aut-mei=Hirohisa kn-aut-name=濱田裕久 kn-aut-sei=濱田 kn-aut-mei=裕久 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部衛生学教室 en-keyword=患者紹介 kn-keyword=患者紹介 en-keyword=紹介率 kn-keyword=紹介率 en-keyword=入院率 kn-keyword=入院率 en-keyword=手術率 kn-keyword=手術率 en-keyword=救急紹介率 kn-keyword=救急紹介率 END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=1-2 article-no= start-page=147 end-page=159 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Neurophysiological study of deep brain stimulation for the treatment of deafferentation pain Part 2.

As a preliminary experiment, the relationship between the waveform of the SEP and the anatomical structure of the brain was examined in cats. The infraorbital nerve was stimulated and the SEP was recorede around the VPM. From the rostral edge of the medial leminiscus (ML), a high voltage positive wave was recorded, and from the ventral side of the VPM a wide negative wave with positive wavelets was recorded. For the treatment of three cases of thalamic pain, the deep cerebral SEP was recorded during the insertion of a chronic electrode for deep brain stimulation. By contralateral median nerve stimulation, the high voltage posotive waves (peak latency ; 13-15msec) from the ML and the subsequent unerven waves from the VPL were recorded along the trajectory. The later uneven waves were composed of wide negative waves and positive wavelets, which were thought to be derived from the synaptic activity of the VPL and thalamocortical rediation, respectively. Effective pain relief was obtained at the border zone of the ventral VPL and the ML, where the characteristic waves of the VPL changed to those of the ML. The deep cerebral SEP can be used for the identification of target points electrophysiologically. en-copyright= kn-copyright= en-aut-name=TomitaSusumu en-aut-sei=Tomita en-aut-mei=Susumu kn-aut-name=富田享 kn-aut-sei=富田 kn-aut-mei=享 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部脳神経外科学教室 en-keyword=deafferentation pain kn-keyword=deafferentation pain en-keyword=deep brain stimulation kn-keyword=deep brain stimulation en-keyword=sensory evoked potential kn-keyword=sensory evoked potential en-keyword=leminiscus medialis kn-keyword=leminiscus medialis en-keyword=nucleus ventrocaudalis kn-keyword=nucleus ventrocaudalis END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=5-6 article-no= start-page=571 end-page=579 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The cytoskeleton of the pancreatic acinar cells observed by detergent perfusion method kn-title=Detergent 灌流法による膵臓線房細胞の細胞骨格の観察 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To investigate the cytoskeleton of the pancreatic acinar cells by electron microscopy, the pancreas of several species (dog, rabbit guinea pig, rat and mouse) was perfused with a mixture of a low concentration of glutaraldehyde and Triton X-100 via the pancreatic duct. After perfusion, the pancreas was fixed with 2.5% glutaraldehyde and processed for scanning and transmission electron microscopy. Scanning electron microscopy demonstrated that the water-soluble cytoplasmic matrices were successively removed by the detergent treatment. Transmission electron microscopy demontrated that without detergent treatment, the acinar cells had many secretory granules at the apical region, the nuclei were located at the base of the cell, and rough-surfaced endoplasmic reticulum and mitochondria throughout the cytoplasm. Microvilli were present at the luminal side and apical subplasmalemmal region showed a homogeneous appearance. With detergent treatment, the core filament in microvilli projected into the apical terminal web which attached to the junctional complex at the lateral membrane. Intermediate filamemts and microtubules were observed in the cytoplasm around the nuclei, and thin filaments were also found around the secretory granules. en-copyright= kn-copyright= en-aut-name=TanakaYukiko en-aut-sei=Tanaka en-aut-mei=Yukiko kn-aut-name=田中由紀子 kn-aut-sei=田中 kn-aut-mei=由紀子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一解剖学教室 en-keyword=膵臓 kn-keyword=膵臓 en-keyword=細胞骨格 kn-keyword=細胞骨格 en-keyword=detergent 灌流法 kn-keyword=detergent 灌流法 en-keyword=電子顕微鏡 kn-keyword=電子顕微鏡 END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=1-2 article-no= start-page=65 end-page=76 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=An electroencephalographic study in enuresis kn-title=夜尿症の脳波学的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To clarify the pathophysiology of nocturnal enuresis and to establish its rational classification and treatment, clinical and electroencephalographic studies were made on 404 enuretic children, including an overnight polysomnographic investigation on 55 cases. EEG was normal in only 76 cases(18.8%). Background EEG abnormalities were observed in 226 cases(55.9%). This suggested the presence of brain immaturity or dysmaturity in enuretic children. Epileptic discharges were detected in 94 cases(23.3%), but not concomitant with the enuretic events. The epileptic mechanism may not play a primary role in the manifestation of enuresis. Specific EEG patterns of subcortical origin, i.e., 6 c/s wave-and-spike phantom, 14&6 c/s positive epikes, anterior theta burst, and mu rhythm, were detected in as many as 188 cases(46.5%). This indicates the importance of subcortical brain dysfunction in enuresis. During overnight polysomnographic recordings, 38 enuretic episodes were observed in 30 cases. Twenty eight episodes appeared in light sleep, 8 episodes in deep sleep, but only 2 episodes in REM sleep. According to the arousal response at the time of enuresis, enuretics were properly classified into arousal type(12 cases) and non-arousal type(18 cases). Prognosis was favourable in the cases whose enuresis appeared in light sleep and also in the arousal type enuretics. en-copyright= kn-copyright= en-aut-name=InoueHideo en-aut-sei=Inoue en-aut-mei=Hideo kn-aut-name=井上英雄 kn-aut-sei=井上 kn-aut-mei=英雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部小児科学教室 en-keyword=夜尿症 kn-keyword=夜尿症 en-keyword=脳波 kn-keyword=脳波 en-keyword=終夜脳波 kn-keyword=終夜脳波 en-keyword=睡眠ポリグラフ kn-keyword=睡眠ポリグラフ en-keyword=予後 kn-keyword=予後 END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=5-6 article-no= start-page=471 end-page=482 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Effects of typtophan metabolites on brain function : Electrocorticographical study kn-title=トリプトファン代謝産物のラット脳機能に対する影響の研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effects of tryptophan (Trp) metabolites administered into right cerebroventricle (1μmol) on the electrocorticograms (ECoG) of rats were studied to investigate the roles of Trp metabolites in the brain function.

Among the 3-hydroxyanthranilic acid metabolites, o-aminophenol induced spike discharges a few min after the administration, and the spike discharges a few min after the administrations, and the spike discharges lasted 60 min. On the other hand, quinolinic acid suppressed ECoG, and picolinic acid had no effect. These electrocorticographic findings suggest that 3- hydroxyanthranilc acid might induce spike discharges after metabolization to o-aminophenol. en-copyright= kn-copyright= en-aut-name=NishijimaYutaka en-aut-sei=Nishijima en-aut-mei=Yutaka kn-aut-name=西嶋寛 kn-aut-sei=西嶋 kn-aut-mei=寛 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学歯学部口腔外科学第一講座 en-keyword=kynurenic acid kn-keyword=kynurenic acid en-keyword=3-hydroxyanthranilic acid kn-keyword=3-hydroxyanthranilic acid en-keyword=o-aminophenol kn-keyword=o-aminophenol en-keyword=quinolinic acid kn-keyword=quinolinic acid en-keyword=experimental seizures kn-keyword=experimental seizures END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=3-4 article-no= start-page=331 end-page=340 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Dectection of human papillomavirus genome in papillomas of head and neck region kn-title=頭頸部乳頭種病変におけるヒトパピロ－マウィルスの関与 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To investigate the etiological role of human papillomavirus (HPV), 14 cases of papillomas in head and neck region were examined virologically and clinicopathogically.

In all cases of multiple laryngeal papillomas, either HPV 6 (2 cases) or HPV 11 (2 cases) genomes were detected. The presence of the HPV genomes provides strong evidence for the HPV etiology of these laryngeal papilloma. In one case of sinonasal papilloma (exophytic type). HPV 6 DNA was detected. No HPV genome was found in the DNA from the remaining 4 sinonasal papillomas. However, their clincopathological findings suggested the viral etiology. No HPV genome was proved in 4 oral papillomas. Furthermore, neither clinical course nor histopathological findings suggested viral etiology. The sensitivity of blot hybridization (Vira probe HPV) in detecting HPV DNA was the same as that of Southern blot hybridization. en-copyright= kn-copyright= en-aut-name=KawakamiTakashi en-aut-sei=Kawakami en-aut-mei=Takashi kn-aut-name=川上登史 kn-aut-sei=川上 kn-aut-mei=登史 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科学教室 en-keyword=乳頭種 kn-keyword=乳頭種 en-keyword=Human Papillomavirus kn-keyword=Human Papillomavirus en-keyword=Dot Blot Hybridization kn-keyword=Dot Blot Hybridization en-keyword=Southern Blot Hybridization kn-keyword=Southern Blot Hybridization END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=9-10 article-no= start-page=871 end-page=884 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=199210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Experimental study on cerebral venous circulatory disturbance kn-title=脳静脈環流障害に関する実験的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=A new experimental model of cerebral venous occlusion was developed and the cerebral hemodynamics and water content using this model were studied. An anatomical study of the cerebral venous system using methacyrl resin showed that the venous system was composed of superficial and deep veins. The superficial veins drained into the superior sagittal sinus (SSS). The SSS was connected to internal and external jugular veins via the transverse sinuses and diploic veins (DV), respectively. The cats were divided into three groups on the basis of the occlusion sites as follows ; Group I : SSS occlusion, Group II : DV occlusion, Group III : occlusion of both the SSS and DV. Intracranial pressure (ICP) and cerebral blood volume (CBV, photoelectric method) were monitored continuously. Local cerebral blood flow (1-CBF) and water content were measured by hydrogen clearance and gravimetric methods, respectively. Somatosensory evoked potential (SEP) was also recorded. Evans blue was injected intravenously to evaluate blood brain barrier permeability. There were no siginificant changes in ICP, 1-CBF or N1 latency of SEP after the occlusioon in Group I or II. However, in Group III, 1-CBF decreased significantly 2 hours after the occlusion as ICP increased gradually. N1 latency of SEP was prolonged and water content increased significantly. CBV increased immediately after the occlusion. There was no extravasated Evans blue. The increase in CBV and water content during sinus occlusion appeared to have led to intracranial hypertension and decrease of 1-CBF, which resulted in neural dysfunction. The brain edema in this model seemed to be hydrostatic edema or cytotoxic edema. en-copyright= kn-copyright= en-aut-name=SaijoToshikazu en-aut-sei=Saijo en-aut-mei=Toshikazu kn-aut-name=西条寿一 kn-aut-sei=西条 kn-aut-mei=寿一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部脳神経外科学教室 en-keyword=cerebral venous circulatory disturbance kn-keyword=cerebral venous circulatory disturbance en-keyword=dural sinus occlusion kn-keyword=dural sinus occlusion en-keyword=brain edema kn-keyword=brain edema en-keyword=cerebral blood flow kn-keyword=cerebral blood flow en-keyword=cerebral blood volume kn-keyword=cerebral blood volume END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=791 end-page=801 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the regulation of eosinophils in bronchial asthma Part 2.

Such cell infiltration seems to be induced by the eosinophil chemotactic factor (ECF). PAF and IL-5 are potent chemoattractants and activators for eosinophils. To evaluate the reactivity of eosinophils in asthmatics under various conditions, the migratory function of eosinophils to PAF and IL-5 was investigated by the modified Boyden chamber method. Eosinophils of asthmatics were highly purified using a flow cytometric method previously reported. The migratory response of the eosinophils of asthmatics was greater than that of healthy suljects. Eosinophils from atopic asthmatics showed a higher response to PAF than those from non-atopic asthmatics. Eosinophils in the attack stage showed a higher response than those in the non-attack stage. Hypodense eosinophils showed an increased migratory response. The migratory response was correlated to the serum concentration of ECP and blood eosinophil count. These findings suggest that the reactivity of eosinophils is heterogenous and relates to the degree of eosinophilia, and that IL-5 as well as PAF plays an important role in the pathogenesis of bronchial asthma. en-copyright= kn-copyright= en-aut-name=TakahashiHisaho en-aut-sei=Takahashi en-aut-mei=Hisaho kn-aut-name=高橋寿保 kn-aut-sei=高橋 kn-aut-mei=寿保 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=Bronchial asthma kn-keyword=Bronchial asthma en-keyword=Eosinophil migratory response kn-keyword=Eosinophil migratory response en-keyword=Platelet-activating factor kn-keyword=Platelet-activating factor en-keyword=Interleukin-5 kn-keyword=Interleukin-5 en-keyword=Eosinophil heterogeneity kn-keyword=Eosinophil heterogeneity END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=5-6 article-no= start-page=641 end-page=654 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=1994 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The pathogenesis of interstitial pneumonia and the role of cytokines kn-title=間質性肺疾患の病態に関する研究―気管支肺胞洗浄液中サイトカインの検討― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Various cytokines are known to participate in the pathogenesis of interstitial pneumonia follewed by lung fibrosis due to the proliferation of fibroblasts and production of collagen fibers. Patients with interstitial pneumonia including idiopathic interstitial pneumonia (IIP) and interstitial pneumonia with collagen vascular disease (IP with CVD) were examined by bronchoalveolar lavage (BAL). Cytokines such as IL-1α,　TGF-α, and TGF-β in BAL fluid were measured by enzyme linked immunosorbent assay (ELISA). The concentrations of TGF-α and TGF-β in BAL fluid of patients with IIP and IP with CVD were higher than those of normal control, while IL-1α, in BAL fluid was detected in few patoents. The level of TGF-β in BAL fluid was higher in patients with greater decreases in pulmonary function and overt fibrosis on chest X-ray film, although TGF-α was higher in patients with milder disorders. The concentrations of TGF-α and TGF-β showed positive correlation with soluble IL-2 receptor as well as procollagen type Ⅲ in BAL fluid. These results indicated that cytokines regulationg lung fibrosis play important roles in the pathogenesis of interstitial pneumonia. en-copyright= kn-copyright= en-aut-name=SugimotoKeisuke en-aut-sei=Sugimoto en-aut-mei=Keisuke kn-aut-name=杉本啓介 kn-aut-sei=杉本 kn-aut-mei=啓介 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=間質性肺疾患 kn-keyword=間質性肺疾患 en-keyword=気管支肺胞洗浄法 (broncho alveolar lavage : BAL) kn-keyword=気管支肺胞洗浄法 (broncho alveolar lavage : BAL) en-keyword=Interleukin 1 (IL-1) kn-keyword=Interleukin 1 (IL-1) en-keyword=transforming growth factor α kn-keyword=transforming growth factor α en-keyword=transforming growth factor β kn-keyword=transforming growth factor β END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=779 end-page=789 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the regulation of eosinophils in bronchial asthma Part 1.

The eosinophil chemotactic factor (ECF) derived from mononuclear cells has been reported to have some effect on the cell infiltration, and interleukin-5 (IL-5), a lymphokine derived from T lymphocytes, to be a factor related to growth, chemotaxis and activation for eosinophils. Lymphocytes accumulated in the bronchoalveolar lavage fluids of non-atopic and severe asthmatics have been shown to be highly responsive to Candida antigen, and high ECF production was observed in non-atopic and severe asthmatics by measurement of ECF activity in the supernatant of peripheral blood mononuclear cells cultured with Candida antigen. In this report, the molecular weight by gel filtration and inhibition test using anti-murine IL-5 antibody were studied to characterize the lymphocyte-derived ECF. Gel filtration analysis of the ECF indicated a molecular weight of 20,000 to 65,000 Da with a peak of activity around 40,000 to 50,000 Da. The ECF activity was reduced by incubation with anti-murine IL-5 antibody, which suggests that the supernatant contains IL-5. ECF from mononuclear cells, containing IL-5, may play an important role in the pathogenesis of eosinophil infiltration in non-atopic and severe asthmatics. en-copyright= kn-copyright= en-aut-name=TakahashiHisaho en-aut-sei=Takahashi en-aut-mei=Hisaho kn-aut-name=高橋寿保 kn-aut-sei=高橋 kn-aut-mei=寿保 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=Bronchial asthma kn-keyword=Bronchial asthma en-keyword=Candida antigen Eosinophil chemotactic factor kn-keyword=Candida antigen Eosinophil chemotactic factor en-keyword=Interleukin-5 kn-keyword=Interleukin-5 END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=7-8 article-no= start-page=749 end-page=757 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=199108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Role of sigma sites in the modulation of neuroleptics-induced dystonia in rats kn-title=抗精神病薬によるジストニアの発現機序に関する実験的研究―σ (sigma) sites の関与について― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recent findings have suggested that neuroleptics exhibit a strong affinity for not only dopamine receptors, but also the sigma sites. Therefore, some clinical or adverse effects of neuroleptics may be due to their action on the sigma sites. This study showed that intrarubral microinjection of 1,3-di-o-tolylguanidine (DTG) or (＋) -3- (3-hydroxyphenyl) -N-1-propyl) piperidine, sigma ligands, and several neuroleptics such as haloperidol caused dystonic reactions in rats resembling tha acute dystonic reaction in humans. The intensity and duration of the dystonia induced by these drugs showed a correlation with their affinities for the sigma sites. These findings raise the possibility that the acute dystonic reaction, one of the motor side effects of neuroleptics, might be mediated via the sigma sites. On the other hand, BMY 14802, an atypical neuroleptic, never caused dystonia after intrarubral microinjection. Furthermore, BMY 14802 still inhibited the dystonia induced by intrarubral microinjection of DTG. This reduction in DTG-induced dystonia by BMY 14802 may result its direct inhibitory effects against DTG at the sites, because BMY 14802 possesses potent sigma affinty. These findings imply that sigma ligands may be divided into two categories, dystonia-reinforcing and -reducing groups. Application of this theory should lead to the elucidation of the mechanism of neuroleptics-induced dystonia and other motor side effects. en-copyright= kn-copyright= en-aut-name=OkumuraKazuya en-aut-sei=Okumura en-aut-mei=Kazuya kn-aut-name=奥村一哉 kn-aut-sei=奥村 kn-aut-mei=一哉 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部神経精神医学教室 en-keyword=sigma sites kn-keyword=sigma sites en-keyword=dystonia kn-keyword=dystonia en-keyword=1, 3 -di-o-tolylguanidine (DTG) kn-keyword=1, 3 -di-o-tolylguanidine (DTG) en-keyword=BMY 14802 kn-keyword=BMY 14802 en-keyword=neuroleptics kn-keyword=neuroleptics END start-ver=1.4 cd-journal=joma no-vol=105 cd-vols= no-issue=5-6 article-no= start-page=575 end-page=587 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=1993 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Correlation between congnitive and motor function in elderly patients with hypertension kn-title=高齢高血圧患者における認知機能と運動機能との関連 en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study examined the correlation between decline in cognitive and motor functions in elderly patients with hypertension. The Mini-Mental State Examination (MMSE) and the Motor Age Test (MOA) were administered to 185 outpatients with hypertension aged 65 or older. In multiple regression analysis, increasing age and history of cerebrovascular disease were significantly related to lower performance on MMSE and MOA. Fewer years of education were also associated with lower performance on MMSE. Vertebral deformity had a significant negative effect on MOA. After controlling other variables, there was a significant correlation between performances of MMSE and MOA. The correlation between cognitive and motor function, which was independent of increasing age and cerebrovascular disease, may indicate common pathogenic mechanisms underlying cognitive and motor deterioration in elderly patients with hypertension. en-copyright= kn-copyright= en-aut-name=MatsuokaHiroaki en-aut-sei=Matsuoka en-aut-mei=Hiroaki kn-aut-name=松岡宏明 kn-aut-sei=松岡 kn-aut-mei=宏明 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部衛生学教室 en-keyword=高齢高血圧症 kn-keyword=高齢高血圧症 en-keyword=ミニ・メンタル・ステート kn-keyword=ミニ・メンタル・ステート en-keyword=運動発達年齢 kn-keyword=運動発達年齢 en-keyword=重回帰分析 kn-keyword=重回帰分析 END start-ver=1.4 cd-journal=joma no-vol=105 cd-vols= no-issue=11-12 article-no= start-page=965 end-page=976 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=19931231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Light and electron microscopic study of rat nonciliated bronchiolar epithelial (Clara) cell in the perinatal period kn-title=周産期ラットにおける肺終末細気管支クララ細胞の観察 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The nonciliated bronchiolar epithelial (Clara) cells are principally distributed in the distal airway, and characterized by the presence of abundant agranular endoplasmic reticulum and electron-dense granules. In the present study, changes in the glycogen, intracellular organella and cytoskeleton occurred in perinatal rat Clara cells were studied by H. E. staining, PAS staining, transmission electron microscopy and detergent perfusion method. The cytoplasm of Clara cells in the prenatal rat contained glycogen and was intensely positive on PAS staining. In 1 to 3-day-old rat, Clara cells with abundant mitochondria, smooth-surfaced endoplasmic reticulum, and filaments in supranuclear area appeared among glycogen-rich Clara cells. In 4 to 7-day-old rat, almost all Clara cells showed no PAS reaction, increased electron-dense granules concomitant with the increase of rough-surfaced endoplasmic reticulum. Abundant filaments and microtubules were observed in the supranuclear area. These results suggest that Clara cells mature after birth and filament formation in these cells occurs with cell maturation and function. en-copyright= kn-copyright= en-aut-name=WadaTatuhiko en-aut-sei=Wada en-aut-mei=Tatuhiko kn-aut-name=和田龍彦 kn-aut-sei=和田 kn-aut-mei=龍彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一解剖学教室 en-keyword=ラット kn-keyword=ラット en-keyword=周産期 kn-keyword=周産期 en-keyword=肺臓 kn-keyword=肺臓 en-keyword=細胞骨格 kn-keyword=細胞骨格 en-keyword=電子顕微鏡 kn-keyword=電子顕微鏡 END start-ver=1.4 cd-journal=joma no-vol=105 cd-vols= no-issue=1-2 article-no= start-page=217 end-page=226 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=19930227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The effects of MCI-186 for ischemic-reperfusion injury during cardiopulumonary bypass kn-title=新しい free radical scavenger MCI-186 の心筋保護効果に関する実験的検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To determine the efficacy of MCI-186, a novel free radical scavenger, in ischemia-reperfusion injury during cardiopulumonary bypass (CPB), the following experimental model was applied. Twenty-one mongrel dogs were subjected to 120 minutes of hypothermic global ischemia by aortic cross clamping with intermittent administration of a cardioplegic solution followed by 60 minutes reperfusion. They were assingend to three groups : group A(n=7), no drug was administerd before reperfusion ; group B(n=7), 1ml/kg of physiological saline was administered by bolus injection through the aortic root just before reprefusion ; group C(n=7), MCI-186 (3mg/ml/kg) dissolved in physiological saline was administered in the same manner as group B. Cardiac function (left ventricular systolic pressure, cardiac output, left ventricular maximum dP/dt) after 60 minutes reperfusion expressed as as percent recovery of pre-ischemic state was superior in group C than in groups A and B. Release of lipidperoxide assayed by the TBA method as the difference between coronary artery and sinus were suppressed in the early phase of reperfusion in group C. Myocardial water content after 60 minutes reperfusion was also less in group C than in group A and B. These findings suggest that administration of MCI-186 before reprefusion after ischemia is effective in protecting the heart from ischemia-reperfusion injury. en-copyright= kn-copyright= en-aut-name=TakeoMasahiko en-aut-sei=Takeo en-aut-mei=Masahiko kn-aut-name=竹尾正彦 kn-aut-sei=竹尾 kn-aut-mei=正彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二外科学教室 en-keyword=MCI-186 kn-keyword=MCI-186 en-keyword=再灌流障害 kn-keyword=再灌流障害 en-keyword=free radical kn-keyword=free radical en-keyword=心筋保護 kn-keyword=心筋保護 en-keyword=体外循環 kn-keyword=体外循環 END start-ver=1.4 cd-journal=joma no-vol=105 cd-vols= no-issue=1-2 article-no= start-page=173 end-page=184 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=19930227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A clinical study of blood coagulation and fibrinolysis in vascular surgery in elderly patients kn-title=高齢者の血管外科手術における凝固線溶動態に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To evaluate the pathogenesis of bleeding tendency in vascular surgery in elderly patients, the serial changes in various parameters of coagulation and fibrinolysis were investigated perioperatively in 30 patients undergoing vascular surgery and in 18 patients undergoing general surgery (control). The platelet count, platelet aggregability and plasminogen activity were lower in the group of vascular surgery than in the control group perioperatively. Thrombin-antithrombin Ⅲ complex(TAT) and plasmin-α(2) plasmin inhibitor complex(PIC) levels were high during operation. Postoperatively, the TAT level gradually decreased but the D-dimer level was high postoperatively. Although platelet aggregability increased significantly with age in the group of general surgery, it tended to decrease in that of vascular surgery. TAT and PIC levels tended to increase but the α(2) plasmin inhibitor(α(2)PI) and fibrinogen levels tended to decrease with age. In 22 patients undergoing graft replacement with abdominal aortic aneurysm, a negative correlation was observed between preoperative α(2)PI and intraoperative blood loss. However, a positive correlation was evident between the preoperative PIC level and intraoperative blood loss. These findings suggest that in vascular surgery, activities of coagulation and fibrinolysis increase and the postoperative hypercoagulable state is transient, although secondary fibrinolysis is stationary in a high level, and that in elderly patients with vascular disorders coagulating factor and anti-fibrinolytic factor tend to decrease. Surgery may induce a bleeding tendency. Furthermore, α(2)PI and PIC might be main factors in intraoperative blood loss. en-copyright= kn-copyright= en-aut-name=SugiyamaAkira en-aut-sei=Sugiyama en-aut-mei=Akira kn-aut-name=杉山章 kn-aut-sei=杉山 kn-aut-mei=章 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二外科学教室 en-keyword=高齢者 kn-keyword=高齢者 en-keyword=血管外科手術 kn-keyword=血管外科手術 en-keyword=凝固線溶動態 kn-keyword=凝固線溶動態 en-keyword=分子マーカー kn-keyword=分子マーカー en-keyword=腹部大動脈瘤 kn-keyword=腹部大動脈瘤 END start-ver=1.4 cd-journal=joma no-vol=120 cd-vols= no-issue=3 article-no= start-page=285 end-page=289 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=20081201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Specificity of QuantiFERON®TB-2G (QFT) in a contactinvestigation in an elementary school kn-title=小児における QuantiFERON®TB-2G の特異度に関する検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: To examine the specificity of QuantiFERON®TB-2G (QFT) in tuberculosis contact investigations of children. Methods: A schoolgirl was diagnosed with smear-positive pulmonary tuberculosis. To determine the extent of tuberculosis infection among contact schoolchildren, tuberculin skin tests were performed on 75 children enrolled in the school. All the children had been vaccinated with BCG at least once. The QFT test was then given to the 68 children who had tuberculin reactions including erythema larger than 10㎜ in diameter. Written informed consent was obtained from a parent of each child. Results: The number of infected subjects was 22 based on tuberculin skin test results. Of the 68 contacts, 1 was positive for QFT, 2 were doubtful positive, and the remaining 65 were negative. During the 2-year follow-up, none of the children developed tuberculosis. Specificity was 95.6%. Conclusions: It was confirmed that the additional use of QFT would reduce the number of indications for chemoprophylaxis cases. The current criteria for the indication of chemoprophylaxis based on a strong tuberculin reaction are considered unreliable, causing many subjects with strong reactions to be given unnecessary preventive medications. en-copyright= kn-copyright= en-aut-name=YoshiokaAkihiko en-aut-sei=Yoshioka en-aut-mei=Akihiko kn-aut-name=吉岡明彦 kn-aut-sei=吉岡 kn-aut-mei=明彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=倉敷市保健所 en-keyword=小児肺結核 (childhood tuberculosis) kn-keyword=小児肺結核 (childhood tuberculosis) en-keyword=接触者健診 (contact investigation) kn-keyword=接触者健診 (contact investigation) en-keyword=化学予防 (chemoprophylaxis) kn-keyword=化学予防 (chemoprophylaxis) en-keyword=特異度 (specificity) kn-keyword=特異度 (specificity) en-keyword=QuantiFERON®TB-2G kn-keyword=QuantiFERON®TB-2G END start-ver=1.4 cd-journal=joma no-vol=120 cd-vols= no-issue=3 article-no= start-page=259 end-page=264 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=20081201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Virus-mediated oncolysis induces danger signals and stimulates cytotoxic T-lymphocyte activity via proteasome activator upregulation kn-title=腫瘍融解ウイルスによる細胞死であるオンコライシスは細胞内に danger signal を発生させ，プロテアソームアクチベーター(PA28)発現を増強することで細胞障害性Ｔリンパ球による免疫応答を活性化する en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=EndoYoshikatsu en-aut-sei=Endo en-aut-mei=Yoshikatsu kn-aut-name=遠藤芳克 kn-aut-sei=遠藤 kn-aut-mei=芳克 aut-affil-num=1 ORCID= en-aut-name=SakaiRyo en-aut-sei=Sakai en-aut-mei=Ryo kn-aut-name=酒井亮 kn-aut-sei=酒井 kn-aut-mei=亮 aut-affil-num=2 ORCID= en-aut-name=OuchiMasaaki en-aut-sei=Ouchi en-aut-mei=Masaaki kn-aut-name=大内正明 kn-aut-sei=大内 kn-aut-mei=正明 aut-affil-num=3 ORCID= en-aut-name=OnimatsuHideki en-aut-sei=Onimatsu en-aut-mei=Hideki kn-aut-name=鬼松秀樹 kn-aut-sei=鬼松 kn-aut-mei=秀樹 aut-affil-num=4 ORCID= en-aut-name=HiokiMasayoshi en-aut-sei=Hioki en-aut-mei=Masayoshi kn-aut-name=日置勝義 kn-aut-sei=日置 kn-aut-mei=勝義 aut-affil-num=5 ORCID= en-aut-name=KagawaShunsuke en-aut-sei=Kagawa en-aut-mei=Shunsuke kn-aut-name=香川俊輔 kn-aut-sei=香川 kn-aut-mei=俊輔 aut-affil-num=6 ORCID= en-aut-name=UnoFutoshi en-aut-sei=Uno en-aut-mei=Futoshi kn-aut-name=宇野太 kn-aut-sei=宇野 kn-aut-mei=太 aut-affil-num=7 ORCID= en-aut-name=WatanabeYuichi en-aut-sei=Watanabe en-aut-mei=Yuichi kn-aut-name=渡邉雄一 kn-aut-sei=渡邉 kn-aut-mei=雄一 aut-affil-num=8 ORCID= en-aut-name=UrataYasuo en-aut-sei=Urata en-aut-mei=Yasuo kn-aut-name=浦田泰生 kn-aut-sei=浦田 kn-aut-mei=泰生 aut-affil-num=9 ORCID= en-aut-name=TanakaNoriaki en-aut-sei=Tanaka en-aut-mei=Noriaki kn-aut-name=田中紀章 kn-aut-sei=田中 kn-aut-mei=紀章 aut-affil-num=10 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name=藤原俊義 kn-aut-sei=藤原 kn-aut-mei=俊義 aut-affil-num=11 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　消化器・腫瘍外科学 affil-num=2 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　消化器・腫瘍外科学 affil-num=3 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　消化器・腫瘍外科学 affil-num=4 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　消化器・腫瘍外科学 affil-num=5 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　消化器・腫瘍外科学 affil-num=6 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　消化器・腫瘍外科学 affil-num=7 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　消化器・腫瘍外科学 affil-num=8 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　消化器・腫瘍外科学 affil-num=9 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　消化器・腫瘍外科学 affil-num=10 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　消化器・腫瘍外科学 affil-num=11 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　消化器・腫瘍外科学 en-keyword=adenovirus kn-keyword=adenovirus en-keyword=telomerase kn-keyword=telomerase en-keyword=dendritic cell kn-keyword=dendritic cell en-keyword=uric acid kn-keyword=uric acid en-keyword=danger signal kn-keyword=danger signal END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=11-12 article-no= start-page=1177 end-page=1181 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=199412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Effect of chronic ethanol administration on mitochondrial membrane fluidity in rat liver and kidneys kn-title=長期エタノール投与ラットの肝および腎ミトコンドリア膜の流動性について en-subtitle= kn-subtitle= en-abstract= kn-abstract=The mitochondrial membrane fluidity in the rat liver and kidneys was measured by electron spin resonance spectrometry using spin labels 5- and 16-doxyl stearic acid (5-, 16-DS) after administration of an ethanol solution (7%) for 3 weeks.

No significant difference in the order parameter was observed in the kidney. On the other hand, in the motion parameter from the 16-DS spectra, which is utilized for the core of the lipid bilayer, no significant change was observed in either the liver or the kidneys.

Daily oral administration of L-Dopa/carbidopa (40mg/kg, 4mg/kg) relieved the hypokinesia and thereafter induced continuous abnormal (choreo-athetoid) involuntary movements (AMI) in upper and lower limbs contralateral to the lesion. These movements were always uniform and continued for a few hours. The author performed a series of pharmacological studies using these VMT-lesioned monkeys. 1) Direct injection of dopamine (500-1000μg/10μl) and apomorphine (500-1500μg/10μl)into the dorsomedial part of the head of the caudate nucleus ipsilateral to the VMT lesion induced the same AIM as those induced by oral administration of L-Dopa/carbidopa. However, intraputaminal injection of these agents induced AIM in bucco-lingual region only. 2) After oral administration of L-Dopa/cabidopa, direct injection of methionine-enkephalin (300μg/10μl), GABA (500-1000μl/10μl) and serotonin (100-200μg/10μl) into the dorsomedial part of the head of the caudate nucleus (HCN) slightly decreased the AIM. However, substance p(200-400μg/10μl) or atropine (100-200μg/10μl) had no effect on the AIM. Neither the direct injection of GABA (500-1000μg/10μl) nor substance P (200-400μg/10μl) into the internal segment of the globus pallidus had any effect of the AIM. 3) The dopaminergic receptor (DA-2) binding study was performed on caudate tissues which were removed 5 weeks after creating the lesion in the unilateral VMT. DA-2 receptor binding of the dorsomedial part of the caudate nucleus, ipsilateral to the lesion, had a higher affinity than that of the ipsilateral ventrolateral part or the contralateral caudate tissue. These results suggest that denervation supersensitivity of the post-synaptic DA-2 receptors in the dorsomedial part of the caudate nucleus is a basic condition for the development of L-Dopa induced AIM, and the postdopaninergic neuronal systems in the caudate nucleus are slightly suppressed by the intra-caudate neurons, of which transmitter substances are methionine-enkephalin, GABA and serotonin. en-copyright= kn-copyright= en-aut-name=SakuraiMasaru en-aut-sei=Sakurai en-aut-mei=Masaru kn-aut-name=桜井勝 kn-aut-sei=桜井 kn-aut-mei=勝 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部脳神経外科学教室 en-keyword=L-Dopa kn-keyword=L-Dopa en-keyword=involuntary movement kn-keyword=involuntary movement en-keyword=striatum kn-keyword=striatum en-keyword=centrally acting agents kn-keyword=centrally acting agents en-keyword=dopaminergic receptor kn-keyword=dopaminergic receptor END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=7-8 article-no= start-page=847 end-page=860 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=199408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The mechanism of human basophil activation through the low affinity IgG receptor (Fc γ RⅡ) : Analysis of calcium mobilization using a new flow cytometric method kn-title=低親和性 IgG レセプター（FcγRⅡ）を介するヒト好塩基球の活性化機序に関する研究―フローサイトメーターによるカルシウム動態の解析― en-subtitle= kn-subtitle= en-abstract= kn-abstract=A new method for flow cytometric analysis of calcium mobilization in human peripheral blood basophils without prior purification was developed. The method is based on dual color analysis of centrifugation-enriched mononuclear cell populations using fluo-3 and phycoerythrin (PE)-conjugated CD2, CD14, CD16, CD19 monoclonal antibodies (mAb) to stain contaminated cells. This technique allows the detection of fluo-3 fluorescence as a measure of an increase in the cytoplasmic free calcium concentration ([Ca(2+)]i) while simulataneously discriminating PE-mAb-unlabelled basophils. To clarify whether the human peripheral blood basophil is activated through the low affinity IgG receptor, Fc γ RⅡ, as well as the high affinity IgE receptor, Fc ε　RⅠ, calcium mobilization after Fc γ RⅡ stimulation was analyzed by this method. After cross-linking of Fc γ RⅡ, transient [Ca(2+)]i elevation was observed but there was no apparent difference with interleukin-3(IL-3)-treated cells, and no significant histamine release was observed with or without short pre-incubation of IL-3. These findings suggest that the cross-linking of Fc γ RⅡ, not only Fc ε　RⅠ, can activate human basophils which may result in mediator release other than histamine. en-copyright= kn-copyright= en-aut-name=SuwakiToshimitsu en-aut-sei=Suwaki en-aut-mei=Toshimitsu kn-aut-name=洲脇俊充 kn-aut-sei=洲脇 kn-aut-mei=俊充 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=basophils kn-keyword=basophils en-keyword=FcγRⅡ kn-keyword=FcγRⅡ en-keyword=fluo-3 kn-keyword=fluo-3 en-keyword=Ca(2+) mobilization kn-keyword=Ca(2+) mobilization END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=7-8 article-no= start-page=789 end-page=798 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=199408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Human T-lymphotropic virus type-Ⅰinfection and pulmonary fibrosing changes in patients with lung cancer kn-title=肺癌患者における HTLV-Ⅰ感染と間質性肺病変に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Thirty-one patients with lung cancer in Okinawa known as HTLV-Ⅰendemic area, and 140 patients in Okayama were evaluated in regard to HTLV-Ⅰinfection and iterstitial pulmonary shadows. The presence of HTLV-Ⅰinfection was examined by the polymerase chain reaction (PCR) method in peripheral blood mononuclear cells, and indirect immunofluorescent (IF) assay in sera. Interstitial pulmonary shadows on the chest roentgenograph, were classified according to the grade of fibrosis. The rate of HTLV-Ⅰinfection in patients with lung cancer was higher than that in healthy controls by IF assay in both districts. The rate of anti-HTLV-Ⅰantibody was higher in lung cancer patients with severe fibrosis than in those with milder fibrosis, but the grade of fibrosis and existence of pX gene had no relation in Okinawa or in Okayama. The incidence of patients with anti-HTLV-Ⅰantibody was higher in patients with adenocarcinoma and squamous cell carcinoma than in those with small cell carcinoma. These findings suggested that HTLV-Ⅰinfection was closely involved in some patients with non-small cell lung cancer having intersitital pulmonary shadows. en-copyright= kn-copyright= en-aut-name=NanbaSeiji en-aut-sei=Nanba en-aut-mei=Seiji kn-aut-name=難波靖治 kn-aut-sei=難波 kn-aut-mei=靖治 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=肺癌 kn-keyword=肺癌 en-keyword=びまん性間質性肺病変 kn-keyword=びまん性間質性肺病変 en-keyword=polymerase chain reaction kn-keyword=polymerase chain reaction en-keyword=間接蛍光抗体法 kn-keyword=間接蛍光抗体法 en-keyword=HTLV-Ⅰ kn-keyword=HTLV-Ⅰ END start-ver=1.4 cd-journal=joma no-vol=108 cd-vols= no-issue=1-2 article-no= start-page=31 end-page=42 dt-received= dt-revised= dt-accepted= dt-pub-year=1996 dt-pub=19960229 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The effects of enflurane on hepatic microaomal cytochrome P-450 kn-title=エンフルランの肝ミクロソーム中チトクローム P-450 に及ぼす影響 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The effects of enflurane and pretratment with phenobarbital or pyridine on hepatic cytochrome P-450(P-450) were studied in mele rats. The rats without pretreatment and those pretreated with phenobarbital or pyridine, were fasted for 24 hours and exposed to 1.2% enflurane at 10% or 21% oxygen for 2 hours. Each group consisted of 6 rets, and rats that were not exposed to enflurane served as control. In the group of rats pretreated with pyridine and exposed to enflurane at 10% oxygen, the content of P-450 and activity of aniline hydroxylation decreased significantly to approximately 61% and 62% of those of the control, respectively. Increases in the plasma level of AST and ALT, and centrilobular necrosis in hepatic tissue were also seen in this group. Administration of disulfuram to rats pretreated with pyridine inhibited the decrease of P-450 and hepatic injury. Threse results indicate that P-450 induced by pyridine was decomposed by exposure to enflurane at 10% oxygen and might cause hepatic injury. en-copyright= kn-copyright= en-aut-name=IshikawaMasami en-aut-sei=Ishikawa en-aut-mei=Masami kn-aut-name=石川雅巳 kn-aut-sei=石川 kn-aut-mei=雅巳 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部麻酔・蘇生学教室 en-keyword=エンフルラン kn-keyword=エンフルラン en-keyword=酵素誘導 kn-keyword=酵素誘導 en-keyword=チトクロームP-450 kn-keyword=チトクロームP-450 en-keyword=肝障害 kn-keyword=肝障害 END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=7-8 article-no= start-page=717 end-page=730 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=199408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Cloning and structural analysis of mouse Apex gene encoding the major apurinic/apyrimidinic endonuclease kn-title=マウス APEX ヌクレアーゼ遺伝子のクローニングと構造解析 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The APEX nuclease is a mammalian multifunctional repair enzyme having 5' apurinic/apyrimidinic (AP) endonuclease, DNA 3' repair diesterase, 3'-5' exonuclease and DNA 3' phosphatase activities. The mouse Apex gene for the enzyme, was isolated from a mouse leukocyte genomic library by plaque hybridization with the mouse Apex cDNA as a probe. The nucleotide sequence of the Apex gene and its 5'-and 3'-flanking regions were determined. With reference to the published Apex cDNA sequence, the mouse Apex gene can be divided into five exons and four introns with a total length of about 2.6 kb. The boundaries between exon and intron follow the GT/AG rule. The translation initiation and termination sites are located in exons Ⅱ and Ⅴ, respectively. A part of the 5' flanking region belongs to a CpG island, which extends to intron Ⅱ. The CpG island is thought to be a putative transcription regulatory region of the Apex gene, a housekeeping gene. en-copyright= kn-copyright= en-aut-name=NagaoKazutaka en-aut-sei=Nagao en-aut-mei=Kazutaka kn-aut-name=長尾一孝 kn-aut-sei=長尾 kn-aut-mei=一孝 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部附属分子細胞医学研究施設病態分子生物学部門 en-keyword=APEX ヌクレアーゼ kn-keyword=APEX ヌクレアーゼ en-keyword=AP エンドヌクレアーゼ kn-keyword=AP エンドヌクレアーゼ en-keyword=DNA 修復酵素 kn-keyword=DNA 修復酵素 en-keyword=Apex 遺伝子（マウス） kn-keyword=Apex 遺伝子（マウス） en-keyword=CpG island kn-keyword=CpG island END start-ver=1.4 cd-journal=joma no-vol=107 cd-vols= no-issue=7-8 article-no= start-page=79 end-page=90 dt-received= dt-revised= dt-accepted= dt-pub-year=1995 dt-pub=19950831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Evaluation of renal function with dynamic MRI-T2* weighted gradient echo technique kn-title=T2*強調gradient echo法を用いたdynamic MRIによる腎機能評価に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To evaluate the usefulness of dynamic MRI of kidneys in healthy volunteers and patients with different 24-hour creatinine clearance (Ccr) levels, a dynamic study that employed the T2* weighted gradient echo technique (FLASH : TR/TE=34/25msec,flip angle=20 degrees) with single images during breathhold was performed on 10 healthy volunteers and 35 patients, all examined for the Ccr and suspected of having renal parenchmal disease after a phantom study.

Large and medium-sized cell bodies, pyramidal to polygonal in shape, were immunostained by anti-Mn-SOD antibody. Most of these were not immunolabeled by anti-GFAP antibody, suggesting that most of the Mn-SOD-lir cells are neurons. These cell bodies were distributed in some selected brain areas with different densities. The densest population of Mn-SOD-lir cells was found in the hypothalamic and limbic structures, and in some brain stem nuclei, such as the thalamic reticular nucleus, the locus ceruleus and the pontine nucleus. Anti-Cu/Zn-SOD antibody immunostained many small round cells throughout both white and gray matter, most of which were also immunolabeled by anti-GFAP antiserum. After intacortical injection of FeCl3, the numbers of Mn- and Cu/Zn-SOD-lir cells per unit area within the adjacent narrow region of the injection site significantly increased 2 and 6 hr after the injection, respectively. en-copyright= kn-copyright= en-aut-name=WangYan en-aut-sei=Wang en-aut-mei=Yan kn-aut-name=王燕 kn-aut-sei=王 kn-aut-mei=燕 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部解剖学第三講座 en-keyword=Mn-SOD kn-keyword=Mn-SOD en-keyword=Cu/Zn-SOD kn-keyword=Cu/Zn-SOD en-keyword=免疫組織化学 kn-keyword=免疫組織化学 en-keyword=ラット脳内分布 kn-keyword=ラット脳内分布 en-keyword=FeCl3　大脳皮質内注入 kn-keyword=FeCl3　大脳皮質内注入 END start-ver=1.4 cd-journal=joma no-vol=111 cd-vols= no-issue=3-8 article-no= start-page=105 end-page=114 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=19990831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Expression of DNA topoisomerase Ⅰ and Ⅱβ in the developing cerebellar plate in rat embryos kn-title=胎児期における小脳皮質の発生とDNAトポイソメラーゼⅠおよびⅡβの発現 en-subtitle= kn-subtitle= en-abstract= kn-abstract=DNA topoisomerases are enzymes that catalyze topological changes of DNA by transiently cleaving one (topo Ⅰ) and a pair of complementary DNA strands (topo Ⅱβ), participating in cellular transactions of DNA. Expression of both enzymes in the developing cerebellar plate in rat embryos was studied immunohistochemically. Neuroepitheliad cells in the ventricular layer expressed topo Ⅰ and topo Ⅱβ on embryonic day 15 (E16) and E16, respectively. On E 16-22, cells in the intermediate layer (IML) are known to undergo extensivc differentiation to become Purkinje cells and deep cerebellar neurons. Many IML cells, immunostained with not only anti-topo Ⅰ and-Ⅱβ but also-calbindin antibodies, were differentiating and migrationg to form the Purkinje cell layer. Cells in the external germinal layer (EGL) on E17, originating from the germinal trigone and spreading over the surface of cerebellar plate, expressed topo Ⅰon E17. Topo Ⅱβ immunoreactive cells, however, were not readily recognized in EGL untill E22. The topo Ⅱβ immunopositive cells resided in the ventral half of the layer, corresponding to the premigratory zone of postnatal EGL. These date suggest the involvement of topo Ⅰand Ⅱβ in DNA metabolism associated with cerebellar development in embryos, especially that of topo Ⅱβ in the processes of neuronal differentiation. en-copyright= kn-copyright= en-aut-name=OgawaMakoto en-aut-sei=Ogawa en-aut-mei=Makoto kn-aut-name=小川誠 kn-aut-sei=小川 kn-aut-mei=誠 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部解剖学第三講座 en-keyword=ラット小脳発生 kn-keyword=ラット小脳発生 en-keyword=小脳板 kn-keyword=小脳板 en-keyword=DNA トポイソメラーゼⅠ kn-keyword=DNA トポイソメラーゼⅠ en-keyword=DNA トポイソメラーゼⅡβ kn-keyword=DNA トポイソメラーゼⅡβ en-keyword=免疫組織化学 kn-keyword=免疫組織化学 END start-ver=1.4 cd-journal=joma no-vol=112 cd-vols= no-issue=3-8 article-no= start-page=39 end-page=46 dt-received= dt-revised= dt-accepted= dt-pub-year=2000 dt-pub=20000831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The effects of health services facilities on medical expenditure for the elderly kn-title=老人保健施設が老人医療費に与える影響について en-subtitle= kn-subtitle= en-abstract= kn-abstract=The first Health Services Facility was started in 1988, to provide the elderly with medical care services in Japan. The facilities have encouraged home care and their numbers have been increasing rapidly. In order to examine the effects of the facilities on medical expenditure for the elderly, cross-sectional and follow-up surveys were conducted with epidemiological analyses of the data from all 47 prefectures in 1990, 1993 and 1996. Multiple regression models were performed using several costs that used medical expenditure for the elderly as the explanatory variables. Furthermore, correlation coefficients between the changes in admission rates, duration of hospitalization, and the change of the numbers of beds in the facilities were calculated. The results are as follows. 1) There was a positive correlation between the cost of the facilities and medical expenditure for the elderly, but the effects have been decreasing with increased construction. 2) There was no relationship between the numbers of beds in the facilities and admission rate to the hospitals, but there was a correlation with the duration of hospitalization. en-copyright= kn-copyright= en-aut-name=OhtsuTadahiro en-aut-sei=Ohtsu en-aut-mei=Tadahiro kn-aut-name=大津忠弘 kn-aut-sei=大津 kn-aut-mei=忠弘 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部衛生学講座 en-keyword=老人保健施設 kn-keyword=老人保健施設 en-keyword=老人医療費 kn-keyword=老人医療費 en-keyword=入院受診率 kn-keyword=入院受診率 en-keyword=入院日数 kn-keyword=入院日数 END start-ver=1.4 cd-journal=joma no-vol=113 cd-vols= no-issue=1 article-no= start-page=1 end-page=16 dt-received= dt-revised= dt-accepted= dt-pub-year=2001 dt-pub=20010428 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Establishment of an adriamycin-resistant human bladder cancer cell line (T-24/ADM) and analysis of the mechanism of resistance kn-title=Adriamycin 耐性ヒト膀胱癌培養細胞株の樹立と耐性機序に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=A human bladder cencer cell line resistant to adriamycin (ADM), T-24/ADM was establishied in vitro by exposing T-24 parent cells to a progressively higher concentration of the drug over an 18 month period. The T-24/ADM was 34.9 times more resistant to ADM than the T-24 parent. The T-24/ADM exhibited cross resistance to ADM derivatives, vinca alkaloid (vindesine, vincristine), etoposide and SN-38, but collateral sensitivity to methotrexate. The biological and biochemical characteristics of T-24/ADM were examined in terms of ADM-resistance. Although a flow cytometric analysis showed that Pglycoprotein is not expressed on the T-24/ADM cells, lower accumalation of the drug caused by decreased uptake and increaced active efflux were observed. The cellular level of glutathione-S-transferase π was 1.8-fold higher than the parent cells and the activity of nuclear extracts of DNA topoisomerase Ⅱ for T-24/ADM assayed by decatenation of kinetoplast DNA was lower, about one-half that of the T-24 parent. Confocal laser microscopy revealed the difference in intracellular distribution of ADM in T-24/ADM; in particular, the accumlation of the drug in the nucleus decreased. Additionally western blot analysis showed an enhanced expression of multidrug resistance-associated protein (MRP) in the T-24/ADM cells. This resistant cell may be used as an experimantal system to elucidate the mechanisum of ADM resistance and also as a model for developing new chemotherapeutic strategies against multi-drug resistant bladder cancer. en-copyright= kn-copyright= en-aut-name=AkebiNaoki en-aut-sei=Akebi en-aut-mei=Naoki kn-aut-name=野比直樹 kn-aut-sei=野比 kn-aut-mei=直樹 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部泌尿器科学教室 en-keyword=adriamycin resistance kn-keyword=adriamycin resistance en-keyword=human bladder cancer cell line kn-keyword=human bladder cancer cell line en-keyword=multidrug resistance kn-keyword=multidrug resistance END start-ver=1.4 cd-journal=joma no-vol=113 cd-vols= no-issue=3 article-no= start-page=247 end-page=259 dt-received= dt-revised= dt-accepted= dt-pub-year=2001 dt-pub=20011231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Expression of amphiphysin Ⅰ, a nerve terminal-enriched protein, in the chromaffin cells of the rat adrenal medulla kn-title=副腎髄質のクロマフィン細胞における神経終末タンパク質 amphiphysin Ⅰの発現 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Amphiphysin (amph)Ⅰ, a protein concentrated in the nerve terminals, plays an essential role in clathrin-mediated endocytosis of synaptic vesicle membrane through an interaction with GTP ase dynamin. A speciffic antibody against amph Ⅰ revealed that the protein was also expressed in adrenal medullary cells. In the postnatal 11th day (P11) and adult rats, combined fluorescence histochemistry for catecholamine-containing cells with immunohistochemistry for amph Ⅰ disclosed strong and weak immunochemical signal of amph Ⅰ in noradrenalin (NA)- and adrenalin (A)-storing cells, respectively. Very strong immunoreactivity to amph Ⅰ was found in the intramedullary neurons but not in the adrenal cortex. In developmental stages, amph Ⅰ was discernible in the medullary chromaffin cells on 16th embryonic day (E16), E19, P0 and P2. Dopamin-β―hydroxylase (a catecholamine-synthesizing enzyme converting dopamin to noradrenalin) was immunohistochemically detected in the chromaffin cells during the parinatal periods. Colocalization of amph Ⅰ with dynamin was seen in NA-cells but not in A-cells. The present findings suggest that amph Ⅰ in the adrenal medullary NA-and A-storing cells is involved in membraine recycling mechanisms, which may be unique to each cell type, through endocytic activities. en-copyright= kn-copyright= en-aut-name=OkamotoYoko en-aut-sei=Okamoto en-aut-mei=Yoko kn-aut-name=岡本洋子 kn-aut-sei=岡本 kn-aut-mei=洋子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=Department of Anatomy III, Okayama University Medical School en-keyword=ラット副腎髄質 kn-keyword=ラット副腎髄質 en-keyword=クロマフィン細胞 kn-keyword=クロマフィン細胞 en-keyword=amphiphysin Ⅰ kn-keyword=amphiphysin Ⅰ en-keyword=免疫組織化学 kn-keyword=免疫組織化学 END start-ver=1.4 cd-journal=joma no-vol=114 cd-vols= no-issue=1 article-no= start-page=39 end-page=51 dt-received= dt-revised= dt-accepted= dt-pub-year=2002 dt-pub=20020530 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A mechanism of development of arterial thrombosis : β2-glycoprotein I-specific ligand and autoantibody kn-title=抗リン脂質抗体症候群における動脈血栓の発症機序：β2-グリコプロテインIに特異的なリガンドと自己抗体の関与 en-subtitle= kn-subtitle= en-abstract= kn-abstract=β2-Glycoprotein I (β2-GPI) is a major antigen for anticardiolipin antibodies (aCL) appeared in patients with antiphospholipid syndrome (APS). We recently reported that β2-GPI specifically binds to oxidized low-density lipoprotein (oxLDL) and that on of the β2-GPI's major ligands derived from oxLDL, oxLig-1, is 9-(7-ketocholest-5-en-3β-yloxy)-9-oxononanoic acid (J. Lipid Res. 42, 697, 2001). In the present study, it was demonstrated that carboxylated variants of cholesteryl linoleate have a critical role for β2-GPI binding.In vitro experiments indicate that oxLDL was uptaken by macrophages via an interaction among the ligand such as oxLig-1, β2-GPI, and anti-β2-GPI autoantibodies. The uptake was not occurred by cholesterol or its ester without a free carboxyl residue, i.e., cholesteryl lenoleate, by cholesterol, or by 7-ketocholesterol alone, even in the presence of β2-GPI and anti-β2-GPI antibodies. Thus, carboxyl variants of cholesteryl ester specific for β2-GPI may mediate anti-β2-GPI Ab-dependent uptake of oxLDL by macrophages and autoimmune atherogenesis developed in APS. en-copyright= kn-copyright= en-aut-name=LiuQingping en-aut-sei=Liu en-aut-mei=Qingping kn-aut-name=劉慶平 kn-aut-sei=劉 kn-aut-mei=慶平 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学院医歯学総合研究科細胞化学分野 en-keyword=antiphospholipid syndrome (APS) kn-keyword=antiphospholipid syndrome (APS) en-keyword=atherosclerosis kn-keyword=atherosclerosis en-keyword=autoantibody kn-keyword=autoantibody en-keyword=β2-glycoprotein I (β2-GPI) kn-keyword=β2-glycoprotein I (β2-GPI) en-keyword=oxidized LDL (oxLDL) kn-keyword=oxidized LDL (oxLDL) END start-ver=1.4 cd-journal=joma no-vol=116 cd-vols= no-issue=1 article-no= start-page=29 end-page=38 dt-received= dt-revised= dt-accepted= dt-pub-year=2004 dt-pub=20040531 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=医学教育概説―教育評価とその運用― en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=板谷裕子 kn-aut-sei=板谷 kn-aut-mei=裕子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=全国共同利用施設岐阜大学医学部医学教育開発センター　MEDC （Medical Education Development Center） en-keyword=Medical education kn-keyword=Medical education en-keyword=Concept formation kn-keyword=Concept formation en-keyword=Insight leaning kn-keyword=Insight leaning en-keyword=Medical interview kn-keyword=Medical interview en-keyword=Tutorial kn-keyword=Tutorial END start-ver=1.4 cd-journal=joma no-vol=117 cd-vols= no-issue=3 article-no= start-page=211 end-page=217 dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=20060104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=骨軟部腫瘍診断と治療における近年の進歩 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=尾﨑敏文 kn-aut-sei=尾﨑 kn-aut-mei=敏文 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 整形外科学 en-keyword=骨軟部腫瘍 kn-keyword=骨軟部腫瘍 en-keyword=治療 kn-keyword=治療 en-keyword=生存率 kn-keyword=生存率 en-keyword=機能再建 kn-keyword=機能再建 END start-ver=1.4 cd-journal=joma no-vol=117 cd-vols= no-issue=1 article-no= start-page=35 end-page=39 dt-received= dt-revised= dt-accepted= dt-pub-year=2005 dt-pub=20050520 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=複合糖質を可視化する en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=大塚愛二 kn-aut-sei=大塚 kn-aut-mei=愛二 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯学総合研究科人体構成学 en-keyword=複合糖質 kn-keyword=複合糖質 en-keyword=組織化学 kn-keyword=組織化学 en-keyword=プロテオグリカン kn-keyword=プロテオグリカン en-keyword=電子顕微鏡 kn-keyword=電子顕微鏡 en-keyword=光学顕微鏡 kn-keyword=光学顕微鏡 END start-ver=1.4 cd-journal=joma no-vol=118 cd-vols= no-issue=3 article-no= start-page=225 end-page=234 dt-received= dt-revised= dt-accepted= dt-pub-year=2007 dt-pub=20070104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=3-ニトロチロシン en-subtitle= kn-subtitle= en-abstract= kn-abstract=種々の機序により産生された活性窒素種 (reactive nitrogen species) によるチロシン残基のニトロ化による3-ニトロチロシン (3-NT) の生成は, 蛋白質の翻訳後修飾の一つとして広く認められている.種々の炎症性疾患組織では, 一酸化窒素・二酸化窒素・ペルオキシナイトライトといった活性窒素種が異なる機序で産生され, 3-NTの産生に関与している. チロシンニトロ化蛋白質の同定や, 蛋白質分子中のチロシンニトロ化部位が決定できるようになり, 蛋白質の寿命, 蛋白質問相互作用に対する悪影響, 蛋白質機能喪失との関連づけが可能になってきた. 測定法としては, 免疫組織化学的手法, ウェスタンブロッティングによる半定量法から, ELISA, HPLC-ECD, LC-MS/MS, GC-MS/MSを用いた定量的な方法がある. 本総説では, 3-NTについて, その生成機序, 測定方法, 予防医学的応用を述べる. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=荻野景規 kn-aut-sei=荻野 kn-aut-mei=景規 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科　公衆衛生学 en-keyword=3ﾝニトロチロシン kn-keyword=3ﾝニトロチロシン en-keyword=活性窒素種 kn-keyword=活性窒素種 en-keyword=翻訳後修飾 kn-keyword=翻訳後修飾 END start-ver=1.4 cd-journal=joma no-vol=119 cd-vols= no-issue=3 article-no= start-page=273 end-page=283 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=20080104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=I The diagnosis of and therapy for breast cancer kn-title=I 乳がんの診断と治療 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=DoiharaHiroyoshi en-aut-sei=Doihara en-aut-mei=Hiroyoshi kn-aut-name=土井原博義 kn-aut-sei=土井原 kn-aut-mei=博義 aut-affil-num=1 ORCID= en-aut-name=TairaNaruto en-aut-sei=Taira en-aut-mei=Naruto kn-aut-name=平成人 kn-aut-sei=平 kn-aut-mei=成人 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部・歯学部附属病院 乳腺・内分泌外科 affil-num=2 en-affil= kn-affil=岡山大学医学部・歯学部附属病院 乳腺・内分泌外科 en-keyword=乳がん kn-keyword=乳がん en-keyword=診断 kn-keyword=診断 en-keyword=手術 kn-keyword=手術 en-keyword=薬物療法 kn-keyword=薬物療法 END
