In Japan, GIS-based evacuation maps are commonly used to support disaster preparedness, but they still have several limitations. In particular, they do not avoid flooded road segments and cannot generate multiple evacuation options at the same time. This study proposes an improved evacuation route method using the free and open-source software QGIS. The method combines flood-depth data with road network processing to remove roads where the predicted water depth is higher than 0.5 m. It also provides several evacuation paths to different shelters at the same time. A case study in Kurashiki City, Okayama Prefecture, demonstrates that about 1.37% of the road network becomes unusable during an inland-flood scenario. Several existing evacuation routes also pass through hazardous areas, but the QGIS-based method avoids these areas in most cases. Since the workflow uses only built-in QGIS functions and does not require programming or plug-ins, it is easy to reproduce and apply in other regions. This study offers a practical and low-cost method to support inland-flood evacuation planning for local governments. en-copyright= kn-copyright= en-aut-name=PanWenliang en-aut-sei=Pan en-aut-mei=Wenliang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PanShijun en-aut-sei=Pan en-aut-mei=Shijun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanetoJunko en-aut-sei=Kaneto en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaKeisuke en-aut-sei=Yoshida en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishiyamaSatoshi en-aut-sei=Nishiyama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=evacuation route kn-keyword=evacuation route en-keyword=hazard mapping kn-keyword=hazard mapping en-keyword=inland flood kn-keyword=inland flood en-keyword=land use analysis kn-keyword=land use analysis en-keyword=QGIS kn-keyword=QGIS END start-ver=1.4 cd-journal=joma no-vol=51 cd-vols= no-issue=5 article-no= start-page=875 end-page=879 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=Endoscopic Transpterygoid Repair of Sphenoid Sinus Meningocele: A Comprehensive Case Report and Literature Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a challenging and uncommon case involving a 53-year-old Japanese man with cerebrospinal fluid (CSF) leakage caused by a meningocele in the lateral recess of the sphenoid sinus. Our innovative treatment approach involved a combination of transpterygoid and endoscopic modified medial maxillectomy techniques, with special emphasis on the preservation of the sphenopalatine artery. This strategic preservation was pivotal to the successful use of the ipsilateral nasoseptal flap for reconstruction, which played a crucial role in the prevention of postoperative CSF leakage. Otolaryngologists and neurosurgeons collaborated to perform the bath-plugging technique; effective collaboration was instrumental to the success of the procedure. This report highlights significant advancement from conventional frontal craniotomy to a more sophisticated endoscopic technique, shows the importance of meticulous surgical planning and execution, emphasizes careful preservation of critical anatomical structures during complex neurosurgical and otolaryngological procedures, and underscores the evolving landscape of surgical approaches for managing complex medical conditions. en-copyright= kn-copyright= en-aut-name=ShimizuAiko en-aut-sei=Shimizu en-aut-mei=Aiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakiharaSeiichiro en-aut-sei=Makihara en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ImotoRyoji en-aut-sei=Imoto en-aut-mei=Ryoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HirashitaKoji en-aut-sei=Hirashita en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AndoMizuo en-aut-sei=Ando en-aut-mei=Mizuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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 Neurosurgery, Kagawa Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Otolaryngology-Head & Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Cerebrospinal fluid leakage kn-keyword=Cerebrospinal fluid leakage en-keyword=Meningocele kn-keyword=Meningocele en-keyword=Transpterygoid approach kn-keyword=Transpterygoid approach en-keyword=Ipsilateral nasoseptal flap kn-keyword=Ipsilateral nasoseptal flap en-keyword=Bath-plug technique kn-keyword=Bath-plug technique END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=17 article-no= start-page=6436 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220826 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Design and Implementation of SEMAR IoT Server Platform with Applications en-subtitle= kn-subtitle= en-abstract= kn-abstract=Nowadays, rapid developments of Internet of Things (IoT) technologies have increased possibilities of realizing smart cities where collaborations and integrations of various IoT application systems are essential. However, IoT application systems have often been designed and deployed independently without considering the standards of devices, logics, and data communications. In this paper, we present the design and implementation of the IoT server platform called Smart Environmental Monitoring and Analytical in Real-Time (SEMAR) for integrating IoT application systems using standards. SEMAR offers Big Data environments with built-in functions for data aggregations, synchronizations, and classifications with machine learning. Moreover, plug-in functions can be easily implemented. Data from devices for different sensors can be accepted directly and through network connections, which will be used in real-time for user interfaces, text files, and access to other systems through Representational State Transfer Application Programming Interface (REST API) services. For evaluations of SEMAR, we implemented the platform and integrated five IoT application systems, namely, the air-conditioning guidance system, the fingerprint-based indoor localization system, the water quality monitoring system, the environment monitoring system, and the air quality monitoring system. When compared with existing research on IoT platforms, the proposed SEMAR IoT application server platform offers higher flexibility and interoperability with the functions for IoT device managements, data communications, decision making, synchronizations, and filters that can be easily integrated with external programs or IoT applications without changing the codes. The results confirm the effectiveness and efficiency of the proposal. en-copyright= kn-copyright= en-aut-name=PandumanYohanes Yohanie Fridelin en-aut-sei=Panduman en-aut-mei=Yohanes Yohanie Fridelin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FunabikiNobuo en-aut-sei=Funabiki en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PuspitaningayuPradini en-aut-sei=Puspitaningayu en-aut-mei=Pradini kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KuribayashiMinoru en-aut-sei=Kuribayashi en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SukaridhotoSritrusta en-aut-sei=Sukaridhoto en-aut-mei=Sritrusta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KaoWen-Chung en-aut-sei=Kao en-aut-mei=Wen-Chung kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of 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=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Department of Informatic and Computer, Politeknik Elektronika Negeri Surabaya kn-affil= affil-num=6 en-affil=Department of Electrical Engineering, National Taiwan Normal University kn-affil= en-keyword=Internet of Things kn-keyword=Internet of Things en-keyword=server platform kn-keyword=server platform en-keyword=SEMAR kn-keyword=SEMAR en-keyword=IoT application system kn-keyword=IoT application system en-keyword=sensor kn-keyword=sensor en-keyword=MQTT kn-keyword=MQTT en-keyword=REST API kn-keyword=REST API END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=12 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Proton beam therapy followed by pembrolizumab for giant ocular surface conjunctival malignant melanoma: A case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=The present study describes proton beam therapy as a clinical option to achieve local control of giant conjunctival melanoma in an aged person, instead of orbital exenteration. An 80‑year‑old woman with one‑year history of left‑eye injection and hemorrhage experienced rapid growth of the ocular surface black mass. At the initial visit, a black, elastic hard, hemorrhage‑prone, thickened mass in the size of 30x40 mm with a presumed wide stalk covered the total area of the lid fissure on the left side. Biopsy of the mass demonstrated anomalous melanin‑containing cells in fibrin and hemorrhage, which were positive for cocktail‑mix antibodies against tyrosinase, melanoma antigen recognized by T cells‑1 and human melanoma black‑45, indicative of malignant melanoma. One month after the initial visit, the patient underwent proton beam therapy at the total dose of 70.4 Gy (relative biological effectiveness) in 32 fractions (~10 min each) in one and a half months. One month after the end of proton beam therapy, 3.5 months from the initial visit, the patient was found by computed tomographic scan to have multiple metastatic lesions in bilateral lung fields. With the evidence of absent BRAF mutation, the patient underwent intravenous administration of pembrolizumab 77.2 mg every three weeks five times in total. Then, three months after proton beam therapy, ocular surface melanoma almost subsided and the clear cornea allowed visualization of the intraocular lens inside the eye. In three weeks, spontaneous corneal perforation was plugged with iris incarceration. The patient died suddenly of unknown cause 7.5 months from the initial visit. The local control of giant conjunctival melanoma was achieved by proton beam therapy, leading to patient's satisfaction and better quality of life. Proton beam therapy, followed by immune checkpoint inhibitors, would become the future standard of care for unresectable giant conjunctival melanoma. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamasakiOsamu en-aut-sei=Yamasaki en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=KatsuiKuniaki en-aut-sei=Katsui en-aut-mei=Kuniaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WakiTakahiro en-aut-sei=Waki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Regenerative and Reconstructive Medicine (Ophthalmology), Okayama University Graduate School of Interdisciplinary Science and Engineering in Health Systems kn-affil= affil-num=2 en-affil=Department of Dermatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Division of Radiation Oncology, Department of Radiology, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of Radiology, Tsuyama Chuo Hospital kn-affil= en-keyword=ocular surface kn-keyword=ocular surface en-keyword=conjunctiva kn-keyword=conjunctiva en-keyword=malignant melanoma kn-keyword=malignant melanoma en-keyword=proton beam therapy kn-keyword=proton beam therapy en-keyword=pembrolizumab kn-keyword=pembrolizumab en-keyword=PD‑1 inhibitor kn-keyword=PD‑1 inhibitor en-keyword=immune checkpoint inhibitor kn-keyword=immune checkpoint inhibitor en-keyword=corneal perforation kn-keyword=corneal perforation END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=2 article-no= start-page=139 end-page=145 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of the Imaging Process for a Novel Subtraction Method Using Apparent Diffusion Coefficient Values en-subtitle= kn-subtitle= en-abstract= kn-abstract=Diffusion-weighted imaging may be used to obtain the apparent diffusion coefficient (ADC), which aids the diagnosis of cerebral infarction and tumors. An ADC reflects elements of free diffusion. Diffusion kurtosis imaging (DKI) has attracted attention as a restricted diffusion imaging technique. The ADC subtraction method (ASM) was developed to visualize restricted diffusion with high resolution by using two ADC maps taken with different diffusion times. We conducted the present study to provide a bridge between the reported basic ASM research and clinical research. We developed new imaging software for clinical use and evaluated its performance herein. This software performs the imaging process automatically and continuously at the pixel level, using ImageJ software. The new software uses a macro or a plugin which is compatible with various operating systems via a Java Virtual Machine. We tested the new imaging software’s performance by using a Jurkat cell bio-phantom, and the statistical evaluation of the performance clarified that the ASM values of 99.98% of the pixels in the bio-phantom and physiological saline were calculated accurately (p<0.001). The new software may serve as a useful tool for future clinical applications and restricted diffusion imaging research. en-copyright= kn-copyright= en-aut-name=HamadaKentaro en-aut-sei=Hamada en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurodaMasahiro en-aut-sei=Kuroda en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshimuraYuuki en-aut-sei=Yoshimura en-aut-mei=Yuuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KhasawnehAbdullah en-aut-sei=Khasawneh en-aut-mei=Abdullah kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BarhamMajd en-aut-sei=Barham en-aut-mei=Majd kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TekikiNouha en-aut-sei=Tekiki en-aut-mei=Nouha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SugiantoIrfan en-aut-sei=Sugianto en-aut-mei=Irfan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=BamgboseBabatunde O. en-aut-sei=Bamgbose en-aut-mei=Babatunde O. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KonishiKohei en-aut-sei=Konishi en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SugimotoKohei en-aut-sei=Sugimoto en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IshizakaHinata en-aut-sei=Ishizaka en-aut-mei=Hinata kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KurozumiAkira en-aut-sei=Kurozumi en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=13 ORCID= en-aut-name=OhnoSeiichiro en-aut-sei=Ohno en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 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=15 ORCID= en-aut-name=AsaumiJunichi en-aut-sei=Asaumi en-aut-mei=Junichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=10 en-affil=Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=11 en-affil=Radiological Technology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=12 en-affil=Central Division of Radiology, Okayama University Hospital kn-affil= affil-num=13 en-affil=Central Division of Radiology, Okayama University Hospital kn-affil= affil-num=14 en-affil=Central Division of Radiology, Okayama University Hospital kn-affil= affil-num=15 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=16 en-affil=Department of Oral and Maxillofacial Radiology, Okayama University Hospital kn-affil= en-keyword=apparent diffusion coefficient kn-keyword=apparent diffusion coefficient en-keyword=ADC subtraction method kn-keyword=ADC subtraction method en-keyword=restricted diffusion kn-keyword=restricted diffusion en-keyword=ImageJ kn-keyword=ImageJ en-keyword=plugin kn-keyword=plugin END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=9 article-no= start-page=2470 end-page=2479 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=2014029 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Microfluidic Approach to the Formation of Internally Porous Polymer Particles by Solvent Extraction en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report the controlled formation of internally porous polyelectrolyte particles with diameters ranging from tens to hundreds of micrometers through selective solvent extraction using microfluidics. Solvent-resistant microdevices, fabricated by frontal photopolymerization, encapsulate binary polymer (P)/solvent (S1) mixtures by a carrier solvent phase (C) to form plugs with well-defined radii and low polydispersity; the suspension is then brought into contact with a selective extraction solvent (S2) that is miscible with C and S1 but not P, leading to the extraction of S1 from the droplets. The ensuing phase inversion yields polymer capsules with a smooth surface but highly porous internal structure. Depending on the liquid extraction time scale, this stage can be carried out in situ, within the chip, or ex situ, in an external S2 bath. Bimodal polymer plugs are achieved using asymmetrically inverted T junctions. For this demonstration, we form sodium poly(styrenesulfonate) (P) particles using water (S1), hexadecane (C), and methyl ethyl ketone (S2). We measure droplet extraction rates as a function of drop size and polymer concentration and propose a simple scaling model to guide particle formation. We find that the extraction time required to form particles from liquid droplets does not depend on the initial polymer concentration but is rather proportional to the initial droplet size. The resulting particle size follows a linear relationship with the initial droplet size for all polymer concentrations, allowing for the precise control of particle size. The internal particle porous structure exhibits a polymer density gradient ranging from a dense surface skin toward an essentially hollow core. Average particle porosities between 10 and 50% are achieved by varying the initial droplet compositions up to 15 wt % polymer. Such particles have potential applications in functional, optical, and coating materials. en-copyright= kn-copyright= en-aut-name=WatanabeTakaichi en-aut-sei=Watanabe en-aut-mei=Takaichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LopezCarlos G. en-aut-sei=Lopez en-aut-mei=Carlos G. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=DouglasJack F. en-aut-sei=Douglas en-aut-mei=Jack F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OnoTsutomu en-aut-sei=Ono en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=CabralJoão T. en-aut-sei=Cabral en-aut-mei=João T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil= Department of Chemical Engineering, Imperial College London kn-affil= affil-num=3 en-affil= Materials Science and Engineering Division, National Institute of Standards and Technology kn-affil= affil-num=4 en-affil=Department of Applied Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Department of Chemical Engineering, Imperial College London kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=CO2 concentration measurements inside expansion-compression engine under high EGR conditions using an infrared absorption method en-subtitle= kn-subtitle= en-abstract=The purpose of this study is to measure the high concentrations of CO2 near a spark plug inside an internal combustion engine, and an infrared absorption method is used for the measurement.

The spark plug sensor was adapted to a compression-expansion machine, and the CO2 concentration near the spark plug was measured by adding a gas mixture, including CO2 to imitate EGR. Next, the EGR ratio was changed from 10 to 40%, and the CO2 concentration was measured. The effect of the CO2 on the flame propagation was investigated by visualizing the bottom view of the compression-expansion machine. The measurements of CO2 mass concentration are in agreement with those predicted by direct-absorption spectroscopy fundamental theory from the crank angle −60 to −15 deg ATDC. The error was less than 20%, and under the conditions with an EGR ratio of 20–40%. en-copyright= kn-copyright= en-aut-name=AhmedFatma B.M. en-aut-sei=Ahmed en-aut-mei=Fatma B.M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EsmailMohamed F.C. en-aut-sei=Esmail en-aut-mei=Mohamed F.C. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawaharaNobuyuki en-aut-sei=Kawahara en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TomitaEiji en-aut-sei=Tomita en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Physics, Faculty of Science, Aswan University kn-affil= affil-num=2 en-affil=Department Mechanical Power Engineering, Faculty of Energy Engineering, Aswan University kn-affil= affil-num=3 en-affil=Department of Mechanical Engineering, Okayama University kn-affil= affil-num=4 en-affil=Department of Mechanical Engineering, Okayama University kn-affil= en-keyword=Infrared absorption method kn-keyword=Infrared absorption method en-keyword=CO2 kn-keyword=CO2 en-keyword=HITRAN kn-keyword=HITRAN en-keyword=EGR kn-keyword=EGR en-keyword=Visualization kn-keyword=Visualization en-keyword=Spark plug sensor kn-keyword=Spark plug sensor END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=1 article-no= start-page=29 end-page=39 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201902 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Histidine-rich Glycoprotein Could Be an Early Predictor of Vasospasm after Aneurysmal Subarachnoid Hemorrhage en-subtitle= kn-subtitle= en-abstract= kn-abstract= Cerebral vasospasm (CVS) is a major contributor to the high morbidity and mortality of aneurysmal subarachnoid hemorrhage (aSAH) patients. We measured histidine-rich glycoprotein (HRG), a new biomarker of aSAH, in cerebrospinal fluid (CSF) to investigate whether HRG might be an early predictor of CVS. A total of seven controls and 14 aSAH patients (8 males, 6 females aged 53.4±15.4 years) were enrolled, and serial CSF and serum samples were taken. We allocated these samples to three phases (T1-T3) and measured HRG, interleukin (IL)-6, fibrinopeptide A (FpA), and 8-hydroxy-2’-deoxyguanosine (8OHdG) in the CSF, and the HRG in serum. We also examined the release of HRG in rat blood incubated in artificial CSF. In contrast to the other biomarkers examined, the change in the CSF HRG concentration was significantly different between the nonspasm and spasm groups (p<0.01). The rat blood/CSF model revealed a time course similar to that of the human CSF samples in the non-spasm group. HRG thus appears to have the potential to become an early predictor of CVS. In addition, the interaction of HRG with IL-6, FpA, and 8OHdG may form the pathology of CVS. en-copyright= kn-copyright= en-aut-name=MatsumotoAtsushi en-aut-sei=Matsumoto en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=ShinomiyaAya en-aut-sei=Shinomiya en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawakitaKenya en-aut-sei=Kawakita en-aut-mei=Kenya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawanishiMasahiko en-aut-sei=Kawanishi en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyakeKeisuke en-aut-sei=Miyake en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KurodaYasuhiro en-aut-sei=Kuroda en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KeepRichard F. en-aut-sei=Keep en-aut-mei=Richard F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TamiyaTakashi en-aut-sei=Tamiya en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=2 en-affil=Department of Medical Technology, Kagawa Prefectural University of Health Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=4 en-affil=Emergency Medical Center, Kagawa University Hospital kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=7 en-affil=Emergency Medical Center, Kagawa University Hospital kn-affil= affil-num=8 en-affil=Department of Neurosurgery, University of Michigan kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Kagawa University Faculty of Medicine kn-affil= en-keyword=biomarker kn-keyword=biomarker en-keyword=histidine-rich glycoprotein kn-keyword=histidine-rich glycoprotein en-keyword=predictor kn-keyword=predictor en-keyword=subarachnoid hemorrhage kn-keyword=subarachnoid hemorrhage en-keyword=vasospasm kn-keyword=vasospasm END start-ver=1.4 cd-journal=joma no-vol=1440 cd-vols= no-issue= article-no= start-page=145 end-page=149 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=20160401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Direct determination of lignin peroxidase released from Phanerochaete chrysosporium by in-capillary enzyme assay using micellar electrokinetic chromatography en-subtitle= kn-subtitle= en-abstract= kn-abstract=Here we describe the application of an in-capillary enzyme assay using micellar electrokinetic chromatography (MEKC) in the determination of enzyme activity in a crude culture medium containing lignin peroxidase released from Phanerochaete chrysosporium (P. chrysosporium). The method consists of a plug–plug reaction between lignin peroxidase and its substrate, veratryl alcohol, the separation of the product, veratraldehyde, from the other components including the enzyme and the culture medium, and the determination of the enzyme activity from the peak area of veratraldehyde produced by the plug–plug reaction. This method is more sensitive than conventional spectrophotometry since the background originates from the enzyme and the culture medium can be removed via MEKC separation. Veratraldehyde was separated at −10 kV in a background electrolyte containing 50 mM tartrate buffer (pH 2.5) and 50 mM sodium dodecyl sulfate (SDS) after a plug–plug reaction in the capillary for 5 min. The calibration curve of veratraldehyde was linear up to 4 pmol (500 μM) with a limit to quantification of 0.026 pmol (3.2 μM) (SN = 10). The activity of lignin peroxidase was directly measured from the peak area of veratraldehyde. The activity of lignin peroxidase released from P. chrysosporium into the medium for 7 days was successfully determined to be 3.40 UL−1. en-copyright= kn-copyright= en-aut-name=HaradaAiri en-aut-sei=Harada en-aut-mei=Airi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SasakiKeiko en-aut-sei=Sasaki en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanetaTakashi en-aut-sei=Kaneta en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Department of Earth Resources Engineering, Graduate School of Engineering, Kyushu University affil-num=3 en-affil= kn-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University en-keyword=Lignin Peroxidase kn-keyword=Lignin Peroxidase en-keyword=Phanerochaete chrysosporium kn-keyword=Phanerochaete chrysosporium en-keyword=Micellar electrokinetic chromatography kn-keyword=Micellar electrokinetic chromatography en-keyword=Capillary electrophoresis kn-keyword=Capillary electrophoresis en-keyword=Enzyme assay kn-keyword=Enzyme assay END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20111231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=鼠径ヘルニアモデルに留置した2種類のMesh Plug の内視鏡的、組織学的評価と検討 kn-title=Impact of Endoscopic and Histological Evaluations of Two Different Types of Mesh Plug for a Groin Hernia Model en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MandaiYasuhiro en-aut-sei=Mandai en-aut-mei=Yasuhiro kn-aut-name=万代康弘 kn-aut-sei=万代 kn-aut-mei=康弘 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=6 article-no= start-page=361 end-page=365 dt-received= dt-revised= dt-accepted= dt-pub-year=2007 dt-pub=200712 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Ectopic Varices Rupture in the Gastroduodenal Anastomosis Successfully Treated with N-butyl-2-cyanoacrylate Injection en-subtitle= kn-subtitle= en-abstract= kn-abstract=

The term "ectopic varices" is used to describe dilated portosystemic collateral veins in unusual locations other than the gastroesophageal region. We recently experienced a rare case of ectopic varices that developed in the gastroduodenal anastomosis after subtotal gastrectomy. A 70-year-old male with liver cirrhosis due to hepatitis C virus infection was admitted for hematemesis and tarry stool. He had received a subtotal gastrectomy with the Billroth-I method for gastric ulcer at 46 years of age. Although emergency endoscopy revealed esophageal and gastric fundal varices, there were no obvious bleeding points. After removal of the coagula, ectopic varices and a fibrin plug were observed on the gastroduodenal anastomosis. During the observation, blood began to spurt from the fibrin plug. N-butyl-2-cyanoacrylate with lipiodol injection succeeded in hemostasis. Splenic angiography showed gastric varices feeding from a short gastric vein and the posterior gastric vein. The blood flow around the bleeding point, as indicated by lipiodol deposition, had decreased, and no feeding vein was observed. Endoscopic and angiographic findings are shown and the treatment for such lesions is discussed.

Sulfated acidic mucopolysaccharides have been found to be significant components of "protein plugs" in patients with chronic pancreatitis. The precise identification of the mucopolysaccharides and their distribution within the protein plugs may clarify the pathogenesis of the plugs. Pure pancreatic juice from five patients with chronic pancreatitis was obtained by endoscopic retrograde catheterization of the papilla of Vater. Enzymes for digestion of the plugs included hyaluronidase of the bovine testes and streptomyces hyalurolyticus, chondroitinase ABC and AC, and sialidase (neuraminidase). Our study indicated that: I) Sialic acid is distributed throughout the plugs and may be a major component, followed by a lesser amount of chondroitin sulfate B. 2) Chondroitin sulfate A, C, D and E and chondroitin may be minor components. 3) Hyaluronic acid is negligible in the plugs.

Angiogenesis involves complex processes mediated by several factors and is associated with inflammation and wound healing. High mobility group box 1 (HMGB1) is released from necrotic cells as well as macrophages and plays proinflammatory roles. In the present study, we examined whether HMGB1 would exhibit angiogenic activity in a matrigel plug assay in mice. HMGB1 in combination with heparin strongly induced angiogenesis, whereas neither HMGB1 nor heparin alone showed such angiogenic activity. The heparin-dependent induction of angiogenesis by HMGB1 was accompanied by increases in the expression of tumor necrosis factor-alpha (TNF-alpha) and vascular endothelial growth factor-A120 (VEGF-A120). It is likely that the dependence of the angiogenic activity of HMGB1 on heparin was due to the efficiency of the diffusion of the HMGB1-heparin complex from matrigel to the surrounding areas. VEGF-A165 possessing a heparin-binding domain showed a pattern of heparin-dependent angiogenic activity similar to that of HMGB1. The presence of heparin also inhibited the degradation of HMGB1 by plasmin in vitro. Taken together, these results suggested that HMGB1 in complex with heparin possesses remarkable angiogenic activity, probably through the induction of TNF-alpha and VEGF-A120.

To determine the extent to which recent advances in biomechanical technology have been implemented and to evaluate these new technologies, 84 unilateral above knee (A/K) amputees and their prostheses were surveyed in the Chugoku-Shikoku district of Japan, especially in regard to the types, sockets and components of A/K prostheses currently in use. Background factors such as age and sex of the A/K amputees and the period after amputation were also surveyed. Of the 84 amputees surveyed, 74 (88.1%) were over 40 years old and 40 (47.6%) were over 60 years old. There were 10 women (11.9%) and 74 men (88.1%). The period after amputation was under 25 years in 58 (69.0%) cases. Regarding the type of A/K prostheses, one-third of the prostheses was of the exoskeletal type and two-thirds were of the endoskeletal type. Although the endoskeletal type is becoming more popular recently, elderly A/K amputees tend to use the exoskeletal type. Thirty-one (36.9%) had plug-fit sockets which are preferable for those who follow the Japanese practice of sitting on the floor, especially for elderly amputees. Thirty-seven (44.0%) had a lock-knee, 27 (73.0%) of which were used by amputees over 60 years old. Seventy-three (86.9%) had a single-axis ankle which is generally considered to be the most stable ankle. Thus, the most common combination of prosthetic components for elderly A/K amputees was the plug-fit socket, lock-knee joint and single-axis ankle.

A 56 years old male with chronic pancreatitis complained of intractable abdominal pain, anorexia, emaciation and peripheral edema. Medical treatment initiated only partial improvement in the general condition and hypoproteinemia. Endoscopic retrograde cholangiopancreatography revealed multiple filling defects in the dilated main pancreatic duct. Endoscopic aspiration of pure pancreatic juice yielded numerous protein plugs. The endoscopic removal of protein plugs from the pancreatic duct resulted in remarkable improvement in symptoms, laboratory findings and ERCP findings. We consider this procedure to be an important new treatment of chronic pancreatitis.

In September, 1979, he had an acute onset of pancreatitis followed by pseudocyst formation and the following combined operations were performed: resection of the pseudocyst, resection of the body and tail of the pancreas along with the spleen, partial resection of the stomach and the transverse colon, and gastroenterostomy according to Billroth I method. He had been followed up at out-patient clinic for chronic pancreatitis and diabetes until January 14,1979 when he was hospitalized for anorexia, loss of weight, pretibial edema, and upper-abdominal pain. The patient's condition was characterized by emaciation (height 152 cm, weight 37 kg), anemia (Hb 7.9g/dl), hypoproteinemia (serum protein 4.2 g/dl) , and hypolipidemia (total cholesterol 73 mg/dl). Abdominal ultrasound, abdominal CT and ERCP revealed stones in the pancreatic duct. Symptoms and objective findings were only partially improved by medical regimens. Subsequently we performed endoscopic cannulation of the pancreatic duct for elimination of pancreatic stones. Successful elimination of large numbers of protein plugs resulted in dramatic improvement of symptoms and objective findings. This procedure proved to add a new important tool in the treatment of chronic pancreatitis. en-copyright= kn-copyright= en-aut-name=TakedaMasahiko en-aut-sei=Takeda en-aut-mei=Masahiko kn-aut-name=武田正彦 kn-aut-sei=武田 kn-aut-mei=正彦 aut-affil-num=1 ORCID= en-aut-name=TanakaJuntaro en-aut-sei=Tanaka en-aut-mei=Juntaro kn-aut-name=田中淳太郎 kn-aut-sei=田中 kn-aut-mei=淳太郎 aut-affil-num=2 ORCID= en-aut-name=TakasugiKiyoshi en-aut-sei=Takasugi en-aut-mei=Kiyoshi kn-aut-name=高杉潔 kn-aut-sei=高杉 kn-aut-mei=潔 aut-affil-num=3 ORCID= en-aut-name=HaradaHideo en-aut-sei=Harada en-aut-mei=Hideo kn-aut-name=原田英雄 kn-aut-sei=原田 kn-aut-mei=英雄 aut-affil-num=4 ORCID= en-aut-name=ManjiTadatomi en-aut-sei=Manji en-aut-mei=Tadatomi kn-aut-name=万治忠福 kn-aut-sei=万治 kn-aut-mei=忠福 aut-affil-num=5 ORCID= en-aut-name=MorinagaHiroshi en-aut-sei=Morinaga en-aut-mei=Hiroshi kn-aut-name=森永寛 kn-aut-sei=森永 kn-aut-mei=寛 aut-affil-num=6 ORCID= en-aut-name=TsurumiTetsuya en-aut-sei=Tsurumi en-aut-mei=Tetsuya kn-aut-name=鶴見哲也 kn-aut-sei=鶴見 kn-aut-mei=哲也 aut-affil-num=7 ORCID= en-aut-name=FujiiYasuhisa en-aut-sei=Fujii en-aut-mei=Yasuhisa kn-aut-name=藤井靖久 kn-aut-sei=藤井 kn-aut-mei=靖久 aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=岡山大学温泉研究所温泉内科学部門 affil-num=2 en-affil= kn-affil=岡山大学温泉研究所温泉内科学部門 affil-num=3 en-affil= kn-affil=岡山大学温泉研究所温泉内科学部門 affil-num=4 en-affil= kn-affil=岡山大学温泉研究所温泉内科学部門 affil-num=5 en-affil= kn-affil=岡山大学医学部附属病院三朝分院内科 affil-num=6 en-affil= kn-affil=岡山大学医学部附属病院三朝分院内科 affil-num=7 en-affil= kn-affil=愛媛県立中央病院内科 affil-num=8 en-affil= kn-affil=愛媛県立中央病院内科 END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue= article-no= start-page=57 end-page=60 dt-received= dt-revised= dt-accepted= dt-pub-year=1983 dt-pub=19830325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Role of endoscopic elimination of protein plug in the treatment of chronic pancreatitis kn-title=内視鏡的純粋膵液採取による慢性膵炎の治療 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Endoscopic aspiration of pure pancreatic juice (ppj) was performed on 65 patients with chronic pancreatitis (cp) or suspected CP primarily for evaluating the validity of biochemical and physiochemical analysis of PPJ in the study of pathogenesis, pathophysiology and diagnosis of CP. PPJ was collected from within the main pancreatic duct by endoscopic retrograde catheterization of the papilla. With increasing experience, it has been revealed that various numbers of protein plugs are contained in PPJ obteined from patients with CP or suspected CP and that endoscopic elimination of protein plugs can provide them with dramatic relief from abdominal pain and back pain. The purpose of this report is to evaluate the role of endoscopic elimination of protein plugs in the treatment of CP. The following conclusions were obteined: (1) endoscopic elimination of protein plugs from within the pancreatic duct is useful. at least on a short-term basis, for relieving abdominal pain and back pain in one-forth of patients with CP or suspected CP; (2) this procedure can be an effective therapeutic tool in selected cases of CP or suspected CP where no prominent stenotic lesions are noted in the major pancreatic duct system and abstinence from alcohol bevarage is strictly observed. en-copyright= kn-copyright= en-aut-name=TanakaJuntaro en-aut-sei=Tanaka en-aut-mei=Juntaro kn-aut-name=田中淳太郎 kn-aut-sei=田中 kn-aut-mei=淳太郎 aut-affil-num=1 ORCID= en-aut-name=TakedaMasahiko en-aut-sei=Takeda en-aut-mei=Masahiko kn-aut-name=武田正彦 kn-aut-sei=武田 kn-aut-mei=正彦 aut-affil-num=2 ORCID= en-aut-name=TakasugiKiyoshi en-aut-sei=Takasugi en-aut-mei=Kiyoshi kn-aut-name=高杉潔 kn-aut-sei=高杉 kn-aut-mei=潔 aut-affil-num=3 ORCID= en-aut-name=HaradaHideo en-aut-sei=Harada en-aut-mei=Hideo kn-aut-name=原田英雄 kn-aut-sei=原田 kn-aut-mei=英雄 aut-affil-num=4 ORCID= en-aut-name=ManjiTadatomi en-aut-sei=Manji en-aut-mei=Tadatomi kn-aut-name=万治忠福 kn-aut-sei=万治 kn-aut-mei=忠福 aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=岡山大学温泉研究所 affil-num=2 en-affil= kn-affil=岡山大学温泉研究所 affil-num=3 en-affil= kn-affil=岡山大学温泉研究所 affil-num=4 en-affil= kn-affil=岡山大学温泉研究所 affil-num=5 en-affil= kn-affil=岡山大学医学部附属三朝分院 END start-ver=1.4 cd-journal=joma no-vol=59 cd-vols= no-issue= article-no= start-page=68 end-page=82 dt-received= dt-revised= dt-accepted= dt-pub-year=1988 dt-pub=198808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Etiology and pathogenesis of chronic pancreatitis kn-title=慢性膵炎の成因，病態と発生機序 en-subtitle= kn-subtitle= en-abstract=Main etiologies of chronic pancreatitis (CP)include "alcoholic" (60%), "idiopathic" (27%)and "biliary" (8%). Clinico-pathological features comprise intractable abdominal pain, maldigestion secodary to exocrine pancreatic insufficiency and diabetes secondary to endocrine pancreatic insufficiency. Death is not infrequent during follow-up. Pathogenesis and evolution of alcoholic CP were discussed in connection with "Big Duct Theory", "Toxic-Metabolic Theory", and "Protein Plug Theory". Diet and congenital predisposition as well as alcoholic comsumption play important roles in various combinations in the pathogenesis and evolution of CP. Important initial lesins of alcoholic CP are probably : (1) pancreatic ductular Obstruction due to proetin plug formation resulting from increased protein and mucoprotein concentration in pancreatic juice ; (2) damage and sloughing of ductular epithelia caused by protein plugs or by a direct toxic effect of ethanol secreted into pancreatic juice, and subsequent ductular stenosis and peri-ductular fibrosis. Parenchymal destruction with interstitial fibrosis is induced upstream to the ductular lesions. These, structural abnormalities and multiple biochemical abnormalities of pancreatic juice further lead to self-perpetuating evolution. Anti-acinar-cell antibody, anti-duet-cell antibody and immune complex in serum are most probably mere epiphenomena and not the causes of CP. kn-abstract=慢性膵炎の成因の主たるものは，アルコール性，特発性，胆石性である。病態面では，社会的・家庭的にもっとも責任が重い壮年期に頑固な疼痛，消化吸収障害，二次性糖尿病のために生活の質が低下することが問題になる。経過中に併発してくる膵およびそのほかの臓器の癌，および糖尿病の合併症による死亡も少なくない。アルコール性慢性膵炎の初期病変の発生機序としては，①膵過分泌の結果として細膵管内に形成される蛋白栓による膵液流出障害と，②蛋白栓あるいはアルコールの直接障害作用による細膵管上皮の損傷，およびその結果生じる膵管狭窄による膵液流出障害が注目されている。膵液流出障害はその上流域に実質細胞の破壊と間質の線維化をおこす。膵液には多くの生化学的異常が認められ，いったん発生した膵管の構造異常とあいまって慢性膵炎進展の原因となる。素因および栄養のアンバランスは発症，進展の促進因子となる。発症を予防し，進展を阻止する手段を開発するためには素因および飲酒・食事を含む環境因子の解析が今後の重要な課題である。 en-copyright= kn-copyright= en-aut-name=HaradaHideo en-aut-sei=Harada en-aut-mei=Hideo kn-aut-name=原田英雄 kn-aut-sei=原田 kn-aut-mei=英雄 aut-affil-num=1 ORCID= en-aut-name=MatsumotoShuji en-aut-sei=Matsumoto en-aut-mei=Shuji kn-aut-name=松本秀次 kn-aut-sei=松本 kn-aut-mei=秀次 aut-affil-num=2 ORCID= en-aut-name=OchiKoji en-aut-sei=Ochi en-aut-mei=Koji kn-aut-name=越智浩二 kn-aut-sei=越智 kn-aut-mei=浩二 aut-affil-num=3 ORCID= en-aut-name=TakedaMasahiko en-aut-sei=Takeda en-aut-mei=Masahiko kn-aut-name=武田正彦 kn-aut-sei=武田 kn-aut-mei=正彦 aut-affil-num=4 ORCID= en-aut-name=SenouToshinobu en-aut-sei=Senou en-aut-mei=Toshinobu kn-aut-name=妹尾敏伸 kn-aut-sei=妹尾 kn-aut-mei=敏伸 aut-affil-num=5 ORCID= en-aut-name=IrieSeiji en-aut-sei=Irie en-aut-mei=Seiji kn-aut-name=入江誠治 kn-aut-sei=入江 kn-aut-mei=誠治 aut-affil-num=6 ORCID= en-aut-name=TanakaJuntaro en-aut-sei=Tanaka en-aut-mei=Juntaro kn-aut-name=田中淳太郎 kn-aut-sei=田中 kn-aut-mei=淳太郎 aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部環境病態研究施設成人病学分野 affil-num=2 en-affil= kn-affil=岡山大学医学部環境病態研究施設成人病学分野 affil-num=3 en-affil= kn-affil=岡山大学医学部環境病態研究施設成人病学分野 affil-num=4 en-affil= kn-affil=岡山大学医学部環境病態研究施設成人病学分野 affil-num=5 en-affil= kn-affil=岡山大学医学部環境病態研究施設成人病学分野 affil-num=6 en-affil= kn-affil=岡山大学医学部環境病態研究施設成人病学分野 affil-num=7 en-affil= kn-affil=岡山大学医学部環境病態研究施設成人病学分野 en-keyword=慢性膵炎 (Chronic pancreatitis) kn-keyword=慢性膵炎 (Chronic pancreatitis) en-keyword=成因 (Etiology) kn-keyword=成因 (Etiology) en-keyword=発生機序 (Pathogenesis) kn-keyword=発生機序 (Pathogenesis) END start-ver=1.4 cd-journal=joma no-vol=70 cd-vols= no-issue=2 article-no= start-page=583 end-page=588 dt-received= dt-revised= dt-accepted= dt-pub-year=1958 dt-pub=19580228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the Effect of Acrifuran on the Liver Function Part Ⅲ The effect of Acrifuran on the liver function of rabbit kn-title=肝機能に及ぼすAcrifuranの影響 第3編 家兎肝機能に及ぼすAcrifuranの影響 en-subtitle= kn-subtitle= en-abstract= kn-abstract=I gave 5% Glucose solution with 1mg% of Acrifuran (3.6-Diamino-Furfurol-10-Methyl-Acridium Chloride) to normal rabbits and the rabbits with benign and severe liver damage caused by the use of Carbon tetrachloride.

Protein plugs were obtained by endoscopic cannulation of the papilla from four patients with calcified chronic pancreatitis (CP), four with non-calcified CP and four with suspected CP. Macroscopic observation revealed two kinds of plugs: opague, whitish plugs of irregular shape (Type I) and translucent jellylike plugs (Type II). The essential fine structure of an amorphous substance filling a reticular network composed of thin, cottony fibrils about 0.1 μ in diameter was shared by both types of plugs. The reticular network of type I plugs were accompanied by thick, smooth fibrils about 0.5 μ in diameter in addition to the cottony fibrils. In four patients, spores of gram-negative bacilli contributed, as smooth thick fibrils, to the network formation of type I plugs. Protein plug formation was considered to start from small aggregates of a loose interlacing cottony network of fibrils with some filling by an amorphous substance and degenerating epithelial cells, followed by maturation with more compact interlacing of fibrils and denser filling by the amorphous substance. Plugs grew most probably by adherence of smaller aggregates and also by layered depositions of the reticular network and amorphous substance. No calcium deposition was detected in protein plugs. en-copyright= kn-copyright= en-aut-name=MikiHiroshi en-aut-sei=Miki en-aut-mei=Hiroshi kn-aut-name=三木洋 kn-aut-sei=三木 kn-aut-mei=洋 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第2内科学教室 en-keyword=protein plugの微細構造・X線分析 kn-keyword=protein plugの微細構造・X線分析 en-keyword=純粋膵液・慢性膵炎 kn-keyword=純粋膵液・慢性膵炎 END start-ver=1.4 cd-journal=joma no-vol=62 cd-vols= no-issue= article-no= start-page=52 end-page=70 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=Alcohol-induced pancreatitis kn-title=アルコール性膵炎 en-subtitle= kn-subtitle= en-abstract=This paper is to review the literature on the epidemiology, clinical pictures and etiopathogenesis of alcohol-induced pancreatitis (AIP). The incidence of AIP has been increasing worldwide, paralleling the increase in alcohol consumption. AIP manifests itself following a longterm consumption of large amounts of alcohol. There is no known threshold value of alcohol consumption in terms of the risk of developing AIP, although the logarithm of the risk of developing AIP is lineally correlated with the amount of alcohol intake. Why some alcoholics develop pancreatitis whereas others with equal consumption of ethanol are spared remains to be explained. Therefore, two additional factors are considered to play important roles in developing AIP : genetic predisposition and diet. The majority of AIP IS chronic pancreatitis (AICP), although a minority can be acute pancreatitis (AIAP). AIAP shows somewhat higher morbidity and mortality than the common variety of acute pancreatitis. If recovered from an attack, AIAP shows morphological and functional restoration. AICP manifests itself with an acute attack of abdominal pain, insidious onset of abdominal pam, or a pain-free variety. An acute attack in AICP resemble that m AIAP ; often these two can be differentiated only by follow-up studies. AICP shows no morphological and functional restoration, and often shows progressive deterioration. Abdominal pain with elevated serum pancreatic enzymes is a predominant clinical picture m the early stage of AICP, whereas in the late stage symptoms and signs deriving from exocrine insufficiency (maldigestion) and endocrine insufficiency (pancreatic diabetes) begin to dominate the clinical pictures. AICP is in the more advanced stage and shows more complications than nonalcoholic chronic pancreatitis at the time of diagnosis. In addition, AICP shows more rapid progress and higher morbidity and mortality. The incidence of microangiopathy in pancreatic diabetes resemble that in primary diabetes, being higher in patients with a longer history of diabetes, those on insulin treatment and those under poorer control. Main causes of death are development of cancer in the upper respiratory and gastrointestinal tract and diabetic complications (hypoglycemic shock, renal failure, and intractable pneumonia), and acute attack of pancreatitis leads to death less frequently. Ductal-Plug theory and classical Toxic-Metabolic theory are most popular to explain the pathogenesis of AIP ; however, increasing evidence has been reported that oxygen free radicals and intracellular activation of zymogens by lysosomal enzymes may be involved in the pathogenesis. kn-abstract=膵炎のうちもっとも頻度が高いアルコール性膵炎（AIP）の疫学，臨床像および発生機序に関する従来の知見を総括した。AIPの大多数は慢性膵炎である。通常は長期にわたる多量の飲酒を背景に発症するが，遺伝的素因および食事因子も重要な役割を演じる。発症初期には血中膵酵素の上昇をともなう腹痛が病像を支配するが，進展すると膵外分泌不全による消化吸収障害と膵内分泌不全による糖尿病が病像を支配するようになる。アルコール性慢性膵炎は非アルコール性慢性膵炎にくらべて確診時にすでに進展した症例が多く，合併症が多く，進行が早く，予後が悪い。死亡の主たる原因は癌の併発と糖尿病の合併症で，膵炎の急性増悪発作がこれにつぐ。併発する癌のなかでは膵癌よりもむしろ上部気道および上部消化管の癌が多い。発生機序としてはDuctal－Plug説とToxic－Metabolic説が有力であるが，最近は細 胞内膵酵素活性化説とFree　Radical説も注目をあびている。 en-copyright= kn-copyright= en-aut-name=HaradaHideo en-aut-sei=Harada en-aut-mei=Hideo kn-aut-name=原田英雄 kn-aut-sei=原田 kn-aut-mei=英雄 aut-affil-num=1 ORCID= en-aut-name=TanakaJuntaro en-aut-sei=Tanaka en-aut-mei=Juntaro kn-aut-name=田中淳太郎 kn-aut-sei=田中 kn-aut-mei=淳太郎 aut-affil-num=2 ORCID= en-aut-name=OchiKoji en-aut-sei=Ochi en-aut-mei=Koji kn-aut-name=越智浩二 kn-aut-sei=越智 kn-aut-mei=浩二 aut-affil-num=3 ORCID= en-aut-name=MatsumotoShuji en-aut-sei=Matsumoto en-aut-mei=Shuji kn-aut-name=松本秀次 kn-aut-sei=松本 kn-aut-mei=秀次 aut-affil-num=4 ORCID= en-aut-name=SenoToshinobu en-aut-sei=Seno en-aut-mei=Toshinobu kn-aut-name=妹尾敏伸 kn-aut-sei=妹尾 kn-aut-mei=敏伸 aut-affil-num=5 ORCID= en-aut-name=lzushiMichihiro en-aut-sei=lzushi en-aut-mei=Michihiro kn-aut-name=出石通博 kn-aut-sei=出石 kn-aut-mei=通博 aut-affil-num=6 ORCID= en-aut-name=TanizakiYoshiro en-aut-sei=Tanizaki en-aut-mei=Yoshiro kn-aut-name=谷崎勝朗 kn-aut-sei=谷崎 kn-aut-mei=勝朗 aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部環境病態研究施設成人病学分野 affil-num=2 en-affil= kn-affil=岡山大学医学部環境病態研究施設成人病学分野 affil-num=3 en-affil= kn-affil=岡山大学医学部環境病態研究施設成人病学分野 affil-num=4 en-affil= kn-affil=岡山大学医学部環境病態研究施設成人病学分野 affil-num=5 en-affil= kn-affil=岡山大学医学部環境病態研究施設成人病学分野 affil-num=6 en-affil= kn-affil=岡山大学医学部附属病院三朝分院 affil-num=7 en-affil= kn-affil=岡山大学医学部附属病院三朝分院 en-keyword=アルコール性膵炎 (Alcohol－induced pancreatitis) kn-keyword=アルコール性膵炎 (Alcohol－induced pancreatitis) en-keyword=慢性膵炎 kn-keyword=慢性膵炎 en-keyword=急性膵炎 kn-keyword=急性膵炎 END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=5-6 article-no= start-page=473 end-page=481 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 2.

Partial or complete relief of pain was obtained in 64 patients with alcoholic CP (66%), nine with biliary CP (100%) and 29 with idiopathic CP (88%). Alcoholic CP showed a significantly lower ratio of pain relief than nonalcoholic CP. A long follow-up period (≧6 years revealed greater pain relief. Patients with discontinued or decreased intake of alcohol showed a significantly higher ratio of pain relief than those continuing drinking. These findings indicate that factors contributing to pain relief are etiological category of CP, drinking habit after diagnosis and length of the follow-up period. Deterioration in quality of life was observed in 42 patients with alcoholic CP, one with biliary CP and 13 with idiopathic CP. Main causes for the deterioration in quality of life were pain, diabetes and loss of interest in work. Abstinence is important for patinets with CP to maintain their quality of life. Endoscopic removal of protein plug contributed to pain relief. Surgical treatment was done in 54 patients with CP. Pain relief was observed in 41 operated patients, and deterioration in the quality of life in 17. Abstinence was important for operated patients as well as non-operated patients to obtain pain relief and maintain the quality of life. Clinically overt steatorrhea was observed in two patients with CP, which was improved by a large dose of enzyme replacement therapy. Aggravation of diabetes had been obsreved, and number of patients dependent on insulin therapy increased during the follow-up period. Diabetes must be treated carefully because diabetes is an important factor contributing to 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=疼痛経過 kn-keyword=疼痛経過 en-keyword=生活の質 kn-keyword=生活の質 en-keyword=治療 kn-keyword=治療 END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=11-12 article-no= start-page=1225 end-page=1235 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=The effects and optimal dose of recombinant human superoxide dismutase during cardiopulmonary bypass kn-title=体外循環下における心筋の虚血再灌流に関する検討-h-SOD の効果と至適投与量- en-subtitle= kn-subtitle= en-abstract= kn-abstract=The efficacy of recombinant human superoxide dismutase (h-SOD) was examined and its optimal dose when given before reperfusion in an experimental canine cardiopulmonary bypass (CPB) model was determined. Mongrel dogs were placed on total CPB for 130 minutes without aortic cross clamping (Group Ⅰ). Others were placed on CPB for 120 minutes aortic cross clamping with intermittent administration of cardioplegic solution and core cooling (Group Ⅱ). Before reperfusion, saline, and 1 mg, 3 mg, 10 mg and 20 mg h-SOD per kilogram were administered via the aortic root as a bolus injection (Group Ⅲ,Ⅳ,Ⅴ,Ⅵ,Ⅶ). Reperfusion after hypothermic global ischemia with aortic cross clamping deteriorated cardiac function (cardiac index, left ventricular maximum dp/dt), increased myocardial water content and increased cardiac enzyme release (creatinine kinase MB isozyme, α-hydroxybutyric dehydrogenase). Administration of 3 mg/㎏ h-SOD significantly ameliorated this reperfusion injury, protected myocardial function early after CPB and gave a desirable peak serum h-SOD concentration. en-copyright=
