The purpose of this study was to observe the electrophysiological effects of long chain acyl carnitine, and to evaluate the protective effect of L-carnitine on the transmembrane action potential impaired by long chain acyl carnitine. Using standard microelectrode techniques, transmembrane action potentials were recorded from isolated canine papillary muscle. Palmitoyl carnitine (0.3mM and 0.6mM) decreased the resting membrane potential, action potential amplitude and maximum upstroke velocity of phase 0, and shortened action potential duration and effective refractory period in a concentration-dependent manner. Application of L-carnitine (25mM) prevented the effect of palmitoyl carnitine (0.3mM) on the transmembrane action potential. These results suggest that long chain acyl carnitine plays an important role in arrhythmogenesis, and that the effect is prevented by L-carnitine.","subitem_description_type":"Abstract"}]},"item_3_publisher_6":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"International Heart Journal Association"}]},"item_3_relation_28":{"attribute_name":"出版社DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1536/ihj.23.623","subitem_relation_type_select":"DOI"}}]},"item_3_rights_7":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"by International Heart Journal Association"}]},"item_3_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00214868","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_20":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"1348673X","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_32":{"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":"Hayashi, Hideharu"}]},{"creatorNames":[{"creatorName":"Suzuki, Yoshikazu"}]},{"creatorNames":[{"creatorName":"Masumura, Yoshinori"}]},{"creatorNames":[{"creatorName":"Kamikawa, Tadashi"}]},{"creatorNames":[{"creatorName":"Kobayashi, Akira"}]},{"creatorNames":[{"creatorName":"Yamazaki, Noboru"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-08-27"}],"displaytype":"detail","filename":"JHeartJ-23-623.pdf","filesize":[{"value":"350.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JHeartJ-23-623.pdf","url":"https://hama-med.repo.nii.ac.jp/record/2409/files/JHeartJ-23-623.pdf"},"version_id":"6e17e3c1-4f79-49cf-980d-2906c9b15315"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Palmitoyl carnitine","subitem_subject_scheme":"Other"},{"subitem_subject":"Free fatty acid","subitem_subject_scheme":"Other"},{"subitem_subject":"Arrhythmogenesis","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Effects of L-carnitine on Action Potential of Canine Papillary Muscle Impaired by Long Chain Acyl Carnitine","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effects of L-carnitine on Action Potential of Canine Papillary Muscle Impaired by Long Chain Acyl Carnitine","subitem_title_language":"en"}]},"item_type_id":"3","owner":"4","path":["11"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-08-27"},"publish_date":"2013-08-27","publish_status":"0","recid":"2409","relation_version_is_last":true,"title":["Effects of L-carnitine on Action Potential of Canine Papillary Muscle Impaired by Long Chain Acyl Carnitine"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-08-02T05:01:34.225610+00:00"}
