The working range of this ELISA was 10-1000  g/L. Histone H3 was not detectable in plasma of healthy volunteers, but significant levels were observed in patients with sepsis and DIC. These levels were higher in non-survivors compared to survivors. Extracellular histones triggered platelet aggregation, leading to thrombotic occlusion of pulmonary capillaries and subsequent right-sided heart failure in mice. These mice displayed signs of DIC, including thrombocytopenia, prolonged prothrombin time, decreased fibrinogen, fibrin deposition in capillaries, and bleeding symptoms. These findings indicate that histones are released into the extracellular space during sepsis and act as a trigger for fatal thrombotic disorders.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_8_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_8_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"494.27","subitem_subject_scheme":"NDC"}]},"item_8_text_41":{"attribute_name":"科研費番号 ","attribute_value_mlt":[{"subitem_text_value":"24659797"}]},"item_8_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"伊藤, 隆史","creatorNameLang":"ja"},{"creatorName":"ITO, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"6518","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000020381171","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]},{"creatorNames":[{"creatorName":"丸山, 征郎","creatorNameLang":"ja"},{"creatorName":"MARUYAMA, Ikuro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"6517","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000020082282","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-28"}],"displaytype":"detail","filename":"24659797.pdf","filesize":[{"value":"239.8 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"24659797.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/8660/files/24659797.pdf"},"version_id":"6dd36a69-a92e-477b-97ea-6eaec6802691"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"集中治療医学","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"敗血症","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"DIC","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"炎症","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"血栓","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"DAMPs","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"敗血症の新規メディエーター\"細胞外ヒストン\"のダイナミズムの解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"敗血症の新規メディエーター\"細胞外ヒストン\"のダイナミズムの解析","subitem_title_language":"ja"},{"subitem_title":"A role of extracellular histones as mediators of death in sepsis","subitem_title_language":"en"}]},"item_type_id":"8","owner":"18","path":["80"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-10-01"},"publish_date":"2013-10-01","publish_status":"0","recid":"8660","relation_version_is_last":true,"title":["敗血症の新規メディエーター\"細胞外ヒストン\"のダイナミズムの解析"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-05-24T00:24:56.833570+00:00"}
