The exercise group ran on a treadmill for 30 min/day at 22 m/min for 7 consecutive days. Immunohistochemistry was used to monitor neural stem cell (NSC) proliferation around the damaged area and ex vivo techniques were used to isolate NSCs from the damaged region in both groups. The number of nestin as a maker of NSC- and Ki67 as a marker of proliferation cell-positive cells observed at 3 and 7 days after TBI was significantly greater in the exercise group than in the non-exercise group (P<0.01). Furthermore, most nestin-positive cells in the exercise group co-localized with Ki67-positive cells. In ex vivo studies, spheres could be isolated from injured brain tissue from the exercise group at 3 and 7 days following TBI, but at only 3 days in the non-exercise group. The number of spheres isolated from injured brain tissue was greater in the exercise group than in the non-exercise group. Spheres were immunopositive for nestin and comprised of NSCs that could differentiate into neurons and glia. Exercise increases the proliferation of NSCs around the damaged area following TBI. Therefore, exercise therapy (rehabilitation) in the early phase following TBI is important for recuperation from cerebral dysfunction induced by TBI.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目:基盤研究(C); 研究期間:2008~2010; 課題番号:20500472; 研究分野:神経化学、神経病理学; 科研費の分科・細目:人間医工学・リハビリテーション科学・福祉工学","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/r/40330245"}]},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/r/70162443"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"},{"subitem_text_value":"研究分担者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"ITO, TATSUKI"},{"subitem_text_language":"en","subitem_text_value":"SATO, TAKAO"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学医学部; 講師"},{"subitem_text_value":"近畿大学医学部附属病院; 教授"}]},"item_8_version_type_12":{"attribute_name":"版","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":"伊藤, 龍生"},{"creatorName":"イトウ, タツキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"佐藤, 隆夫"},{"creatorName":"サトウ, タカオ","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":"2016-02-17"}],"displaytype":"detail","filename":"KAKEN_20500472seika.pdf","filesize":[{"value":"393.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KAKEN_20500472seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/3121/files/KAKEN_20500472seika.pdf"},"version_id":"48580736-3aa8-4cd8-99d7-1b0938dacd35"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"脳外傷","subitem_subject_scheme":"Other"},{"subitem_subject":"リハビリテーション","subitem_subject_scheme":"Other"},{"subitem_subject":"神経幹細胞","subitem_subject_scheme":"Other"},{"subitem_subject":"運動","subitem_subject_scheme":"Other"},{"subitem_subject":"神経再生","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"脳外傷後の運動による神経再生促進効果の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"脳外傷後の運動による神経再生促進効果の研究"}]},"item_type_id":"8","owner":"3","path":["2693","2694"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-07-08"},"publish_date":"2011-07-08","publish_status":"0","recid":"3121","relation_version_is_last":true,"title":["脳外傷後の運動による神経再生促進効果の研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-21T01:46:00.106767+00:00"}
