Experiments were performed in open- and close-chest dogs anesthetized with morphine-α-chloralose-urethane and nitrous oxide. Lacidipine and nifedipine were administered intravenously at 1～30μg/kg. In open-chest dogs, both lacidipine and nifedipine produced dose-dependent decreases in diastolic and mean blood pressures (DBP and MBP) and increases in heart rate (HR) and left ventricular max dP/dt (LV max dP/dt). The decrease in MBP produced by nifedipine was transient; the MBP recovered to a level almost equal to the predrug level in a few minutes. In contrast, the effects of lacidipine were more prolonged except at low dose levels. On the basis of half-life assessed at a dose causing a decrement of MBP of a similar magnitude the hypotensive effect of lacidipine was \u003e9 times longer-lasting than that of nifedipine. Both nifedipine and lacidipine decreased systolic blood pressure (SBP), left ventricular pressure (LVP) and left ventricular end-diastolic pressure (LVEDP) and increased cardiac output (CO). Lacidipine and nifedipine decreased total peripheral resistance (TPR) dose-dependently. The decreases were 20～50% for lacidipine and 15～40 % for nifedipine. Coronary blood flow (Cor-F) was increased to 50～175 % of the control after lecidipine and coronary vascular resistance (Cor-R) was decreased to 25～75%, while the changes were 40～240% and 35～70% after nifedipine. Decreases and increases were dose-dependent with both drugs. The increases in Cor-F exceeded those expected from the increases in MVO_2 observed simultaneously. In close-chest dogs, both nifedipine and lacidipine increased carotid and femoral blood flow (Car-F and Fern-F) and dose-dependently decreased carotid and femoral vascular resistance (Car-R and Fem-R). Coincident with the fall in BP renal blood flow (Ren-F) was decreased. Renal vascular resistance (Ren-R) was slightly decreased at all doses except for the maximum dose, at which it increased. The changes observed in blood flow in these vascular beds were less than 50% at the maximum and those in vascular resistance were less than 35%. Changes in MBP and HR were similar to those observed in open-chest dogs. Duration of action of lacidipine was longer than that of nifedipine. Like nifedipine the action of lacidipine was selective towards coronary artery.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "119448", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Hara, Katsutoshi"}]}, {"nameIdentifiers": [{"nameIdentifier": "119449", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Ishibashi, Takaharu"}]}, {"nameIdentifiers": [{"nameIdentifier": "119450", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Hamaguchi, Masami"}]}, {"nameIdentifiers": [{"nameIdentifier": "119451", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Imai, Shoichi"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟医学会"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00182415", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "00290440", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "原, 勝利"}], "nameIdentifiers": [{"nameIdentifier": "119444", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "石橋, 隆治"}], "nameIdentifiers": [{"nameIdentifier": "119445", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "濱口, 政巳"}], "nameIdentifiers": [{"nameIdentifier": "119446", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "今井, 昭一"}], "nameIdentifiers": [{"nameIdentifier": "119447", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-08"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "108(8)_593-608.pdf", "filesize": [{"value": "2.4 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2400000.0, "url": {"label": "108(8)_593-608.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/19180/files/108(8)_593-608.pdf"}, "version_id": "5aa18969-3a59-4530-b764-1ec165054bde"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "lacidipine", "subitem_subject_scheme": "Other"}, {"subitem_subject": "nifedipine", "subitem_subject_scheme": "Other"}, {"subitem_subject": "calcium antagonist", "subitem_subject_scheme": "Other"}, {"subitem_subject": "dog", "subitem_subject_scheme": "Other"}, {"subitem_subject": "カルシウム拮抗薬", "subitem_subject_scheme": "Other"}, {"subitem_subject": "心血行動態", "subitem_subject_scheme": "Other"}, {"subitem_subject": "心筋酸素消費量", "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": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "新規カルシウム拮抗薬 Lacidipineの心血行動態に対する作用", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "新規カルシウム拮抗薬 Lacidipineの心血行動態に対する作用"}, {"subitem_title": "新規カルシウム拮抗薬 Lacidipineの心血行動態に対する作用", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1147"], "permalink_uri": "http://hdl.handle.net/10191/38416", "pubdate": {"attribute_name": "公開日", "attribute_value": "2016-02-18"}, "publish_date": "2016-02-18", "publish_status": "0", "recid": "19180", "relation": {}, "relation_version_is_last": true, "title": ["新規カルシウム拮抗薬 Lacidipineの心血行動態に対する作用"], "weko_shared_id": null}
