Wistar雄性ラットを用い,Ca^<2+>負荷(12mg/kg/min) 20分間後イソプロテレノール(0.6μg/kg/分)を20分間投与した.虚血再灌流実験では左冠動脈前下行枝を結紮5分後再灌流した. K201またはジルチアゼム(各々1mg/kg)はイソプロテレノール投与時あるいは冠動脈結紮10分前に1分間で投与した.各実験で心室頻脈および心室細動の発生頻度,出現時間,持続時間,および死亡率を調べた.また,ダブルプロダクト(平均血圧×心拍数)を算出した. Iso-Vfの発生率は対照群5/6 (83.3%),ジルチアゼム群4/6 (66.7%), K201群0/6 (0%)で, K201はIso-Vfを有意に抑制した(p<0.05).虚血再灌流実験ではRep-Vfの発生率は対照群12/14 (85.7%), K201群3/15 (20.0%),ジルチアゼム群3/9 (33.3%)でK201,ジルチアゼムともに有意に抑制した.以上より, K201は著明にIso-VfおよびRep-Vfを抑制したが,ジルチアゼムはIso-Vfを抑制しなかった. Iso-VfおよびRep-Vfともに発生様式からearly afterdepolarization (EAD)が推測され, K201はEADを抑制する可能性が示唆された.","subitem_description_type":"Other"}]},"item_2_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"学位申請論文","subitem_description_type":"Other"}]},"item_2_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00629581"}]},"item_2_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03855023","subitem_source_identifier_type":"ISSN"}]},"item_2_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"獨協医科大学内科学(心血管・肺)"}]},"item_2_title_3":{"attribute_name":"論文名よみ","attribute_value_mlt":[{"subitem_title":"シンシツ サイドウ ト ソノ ヨクセイ キジョ ニ カンスル ジッケンテキ ケントウ : ベンゾチアゼピン ユウドウタイ K201 ト ジルチアゼム ノ ヒカク ケントウ"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大谷, 直由"},{"creatorName":"オオタニ, ナオユキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-05-24"}],"displaytype":"detail","filename":"KJ00005058760.pdf","filesize":[{"value":"601.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00005058760.pdf","url":"https://dmu.repo.nii.ac.jp/record/656/files/KJ00005058760.pdf"},"version_id":"ea3c4891-0f12-4cc8-b0ea-7855d7d632c7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"K201"},{"subitem_subject":"心室細動"},{"subitem_subject":"early afterdepolarization"},{"subitem_subject":"ジルチアゼム"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"心室細動とその抑制機序に関する実験的検討 : ベンゾチアゼピン誘導体K201とジルチアゼムの比較検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"心室細動とその抑制機序に関する実験的検討 : ベンゾチアゼピン誘導体K201とジルチアゼムの比較検討"}]},"item_type_id":"2","owner":"3","path":["45"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-05-24"},"publish_date":"2017-05-24","publish_status":"0","recid":"656","relation_version_is_last":true,"title":["心室細動とその抑制機序に関する実験的検討 : ベンゾチアゼピン誘導体K201とジルチアゼムの比較検討"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T16:12:40.695681+00:00"}
