Japanese white rabbits anesthetized with nitrogen oxide, oxygen and pancuronium were placed on their sides. The left anterior descending coronary artery was exposed via left thoracotomy. Following a 30-minute ischemia to the coronary artery, a 30-minute infusion of lidocaine at 1.0mg/kg/h or physiological saline was started immediately after the initiation of 120-minute reperfusion. During the experiment, systemic blood pressure was continuously monitored using a catheter placed in the femoral artery, and serum lidocaine concentration was determined periodically. At the end of the experiment, the heart was isolated and treated with Evans blue dye to identify the area at risk (AAR) and the non-risk area. The areas of infarction and the risk area were determined using 1% 2,3,5-triphenyltetrazolium chloride (TTC). Although the systemic arterial pressure at 10 and 20 minutes after the coronary ligation was lower than baseline, no significant differences were observed between the lidocaine and saline groups. The AAR and non-risk areas did not differ significantly between the lidocaine and saline groups. The percentage of infarct size per AAR was 14.4% lower in animals receiving lidocaine infusion during reperfusion than in those receiving saline. These findings indicate that high-dose lidocaine infusion protects the myocardium against ischemia-reperfusion injury without affecting blood pressure during reperfusion.","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"乙第1581号"}]},"item_10006_publisher_5":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"大阪歯科学会"}]},"item_10006_version_type_18":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山林, 一公"},{"creatorName":"ヤマバヤシ, カズトモ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamabayashi, Kazutomo","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-08-01"}],"displaytype":"detail","filename":"otu_1581.txt.pdf","filesize":[{"value":"162.2 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"学位論文","url":"https://osaka-dent.repo.nii.ac.jp/record/70/files/otu_1581.txt.pdf"},"version_id":"5293965d-1440-4239-903a-d847b445e402"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-08-01"}],"displaytype":"detail","filename":"otu_1581.pdf","filesize":[{"value":"243.5 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"論文内容要旨・審査結果要旨","url":"https://osaka-dent.repo.nii.ac.jp/record/70/files/otu_1581.pdf"},"version_id":"c23af9fb-430f-4c80-ae14-21f7aab5aebb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Lidocaine","subitem_subject_scheme":"Other"},{"subitem_subject":"Myocardial protection","subitem_subject_scheme":"Other"},{"subitem_subject":"Myocardial infarction","subitem_subject_scheme":"Other"},{"subitem_subject":"Reperfusion injury","subitem_subject_scheme":"Other"},{"subitem_subject":"Rabbit","subitem_subject_scheme":"Other"},{"subitem_subject":"Lidocaine","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Myocardial protection","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Myocardial infarction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Reperfusion injury","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Rabbit","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Lidocaine protects against myocardial ischemia-reperfusion injury in anesthetized rabbits","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Lidocaine protects against myocardial ischemia-reperfusion injury in anesthetized rabbits"}]},"item_type_id":"10006","owner":"15","path":["11"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-08-01"},"publish_date":"2016-08-01","publish_status":"0","recid":"70","relation_version_is_last":true,"title":["Lidocaine protects against myocardial ischemia-reperfusion injury in anesthetized rabbits"],"weko_creator_id":"15","weko_shared_id":15},"updated":"2023-05-15T14:07:37.753260+00:00"}
