Free radical concentrations in state 4 respiration or the ratio of free radical concentrations in state 4 to state 1 was used as an index of mitochondrial function. Free radical concentrations were represented as ESR intensity. In normal control, ESR intensity increased from 0.115±0.030 (mean ±SD) per mg protein in state 1 to 0.178±0.017 in state 4 (p<0.001). When mitochondria were treated with 10-4M ethanol, on the other hand, ESR intensity decreased from 0.163±0.34 in state 1 to 0.137±0.019 in state 4 (p<0.05). When mitochondria were treated with 10-6M nitroglycerin, in spite of the presence of 10-4M ethanol, ESR intensity increased from 0.124±0.23 in state 1 to 0.153±0.024 in state 4 (p<0.05). ESR intensity in state 1 was increased by the treatment of ethanol (p<0.05), whereas ESR intensity in state 4 was decreased (p<0.001), and these effects were prevented by nitroglycerin (p<0.05). The ratio of ESR intensity in state 4 to state 1 demonstrated more remarkably the effects of ethanol and nitroglycerin. Ethanol reduced the ratio from 1.65±0.47 in the control to 0.86±0.13 (p<0.001) and the reduction was prevented by nitroglycerin to 1.25±0.23 (p<0.01). It is concluded that nitroglycerin prevented the impairment of free radical formation of the mitochondria induced by ethanol, presumably by a mitochondrial membrane-stabilizing action.","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.22.627","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":"Suzuki, Yoshikazu"}]},{"creatorNames":[{"creatorName":"Kamikawa, Tadashi"}]},{"creatorNames":[{"creatorName":"Yamamoto, Mitate"}]},{"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-22-627.pdf","filesize":[{"value":"520.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JHeartJ-22-627.pdf","url":"https://hama-med.repo.nii.ac.jp/record/2422/files/JHeartJ-22-627.pdf"},"version_id":"3e332fc0-8118-4606-9b15-104d4bc121cf"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Respiratory control ratio","subitem_subject_scheme":"Other"},{"subitem_subject":"Free radical concentrations in state 4 respiration","subitem_subject_scheme":"Other"},{"subitem_subject":"The ratio of free radical concentrations in state 4 to state 1","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":"Effect of Nitroglycerin on the Free Radical Formation of Myocardial Mitochondria Impaired by Ethanol","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effect of Nitroglycerin on the Free Radical Formation of Myocardial Mitochondria Impaired by Ethanol","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":"2422","relation_version_is_last":true,"title":["Effect of Nitroglycerin on the Free Radical Formation of Myocardial Mitochondria Impaired by Ethanol"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-08-02T05:02:08.167040+00:00"}
