Eight-week-old male Wistar rats were orally administered with 3 doses per day of 1 mL of 0.05% (PA0.05), 0.5% (PA0.5) or 5% (PA5) PA for 1 week. Control animals received the same volume of distilled water. We also examined the effect of a single dose of 0.5% PA. Blood and muscle were collected from rats 1 h after the final administration. Scavenging activity against superoxide anions in the plasma and m. soleus (Sol), m. plantaris (Pla), deep and surface areas of the m. gastrocnemius (GasD and GasS, respectively) and myocardium (Hrt) was determined using ESR with the spin trap, 5,5-dimethyl-1-pyrroline-N-oxide The scavenging activity in plasma for all groups given PA was 34%-44% higher than the control (p \u003c 0.05). The scavenging activity in Hrt, Sol and GasD increased by up to 50% compared with the control and tended to increase depending on the dose of PA (p \u003c 0.05). The impact of a single dose of PA was undetectable in all tissues. These results suggested that 1 week of oral PA improves the radical-scavenging activity in both plasma and muscle, especially in highly oxidative muscle. A single dose of PA was insufficient to improve the antioxidative capacity of muscle tissues. © 2007 NRC.", "subitem_description_type": "Abstract"}]}, "item_4_description_5": {"attribute_name": "提供者所属", "attribute_value_mlt": [{"subitem_description": "金沢大学教育学部保健体育", "subitem_description_type": "Other"}]}, "item_4_publisher_17": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "National Research Council Canada"}]}, "item_4_relation_12": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isIdenticalTo", "subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1139/H07-073", "subitem_relation_type_select": "DOI"}}]}, "item_4_source_id_11": {"attribute_name": "NCID", "attribute_value_mlt": [{"subitem_source_identifier": "AA12088809", "subitem_source_identifier_type": "NCID"}]}, "item_4_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1715-5312", "subitem_source_identifier_type": "ISSN"}]}, "item_4_version_type_25": {"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": "Masuda, Kazumi"}], "nameIdentifiers": [{"nameIdentifier": "176", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "50323283", "nameIdentifierScheme": "e-Rad", "nameIdentifierURI": "https://kaken.nii.ac.jp/ja/search/?qm=50323283"}, {"nameIdentifier": "50323283", "nameIdentifierScheme": "金沢大学研究者情報", "nameIdentifierURI": "http://ridb.kanazawa-u.ac.jp/public/detail.php?kaken=50323283"}, {"nameIdentifier": "50323283", "nameIdentifierScheme": "研究者番号", "nameIdentifierURI": "https://nrid.nii.ac.jp/nrid/1000050323283"}]}, {"creatorNames": [{"creatorName": "Hori, Tatsuya"}], "nameIdentifiers": [{"nameIdentifier": "3266", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Tanabe, Kai"}], "nameIdentifiers": [{"nameIdentifier": "3267", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kano, Yutaka"}], "nameIdentifiers": [{"nameIdentifier": "3268", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hirayama, Aki"}], "nameIdentifiers": [{"nameIdentifier": "3269", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nagase, Shoji"}], "nameIdentifiers": [{"nameIdentifier": "3270", "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": "2017-10-02"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "ED-PR-MASUDA-K-1097.pdf", "filesize": [{"value": "174.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 174300.0, "url": {"label": "ED-PR-MASUDA-K-1097.pdf", "url": "https://kanazawa-u.repo.nii.ac.jp/record/536/files/ED-PR-MASUDA-K-1097.pdf"}, "version_id": "b9af859a-5d62-458c-9204-330ce2cba3c2"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Antioxidative activity", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Electron spin resonance", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Myocardium", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Phytochemical", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Superoxide dismutase", "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": "Proanthocyanidin promotes free radical-scavenging activity in muscle tissues and plasma", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Proanthocyanidin promotes free radical-scavenging activity in muscle tissues and plasma"}]}, "item_type_id": "4", "owner": "3", "path": ["16"], "permalink_uri": "http://hdl.handle.net/2297/9542", "pubdate": {"attribute_name": "公開日", "attribute_value": "2017-10-02"}, "publish_date": "2017-10-02", "publish_status": "0", "recid": "536", "relation": {}, "relation_version_is_last": true, "title": ["Proanthocyanidin promotes free radical-scavenging activity in muscle tissues and plasma"], "weko_shared_id": -1}

内容記述 | The present study was carried out to clarify the effect of oral administration of proanthocyanidin (PA) on radical-scavenging activity in muscle and plasma using electron spin resonance (ESR). Eight-week-old male Wistar rats were orally administered with 3 doses per day of 1 mL of 0.05% (PA0.05), 0.5% (PA0.5) or 5% (PA5) PA for 1 week. Control animals received the same volume of distilled water. We also examined the effect of a single dose of 0.5% PA. Blood and muscle were collected from rats 1 h after the final administration. Scavenging activity against superoxide anions in the plasma and m. soleus (Sol), m. plantaris (Pla), deep and surface areas of the m. gastrocnemius (GasD and GasS, respectively) and myocardium (Hrt) was determined using ESR with the spin trap, 5,5-dimethyl-1-pyrroline-N-oxide The scavenging activity in plasma for all groups given PA was 34%-44% higher than the control (p < 0.05). The scavenging activity in Hrt, Sol and GasD increased by up to 50% compared with the control and tended to increase depending on the dose of PA (p < 0.05). The impact of a single dose of PA was undetectable in all tissues. These results suggested that 1 week of oral PA improves the radical-scavenging activity in both plasma and muscle, especially in highly oxidative muscle. A single dose of PA was insufficient to improve the antioxidative capacity of muscle tissues. © 2007 NRC. | |||||
