Sixteen adult, nine-week-old male Wistar rats (body weight: 260 g-285 g) were used for this study. The four rats of the control group were raised normally for two weeks. The other 12 rats had their right knee joints immobilized with a cast fixator for two weeks. The four rats of the contracture group were euthanatized immediately after contracture had been achieved. The four rats of the stretch group were subjected to stretching of the immobilized knee for two weeks. The four rats of the non-stretch group were not subjected to stretching. Stretching consisted of five cycles of 50-second stretching and a 10-second rest. The trunk of the rats of the stretch group was immobilized, and the ankle was stretched in the caudal direction. The knee joints excised after sacrifice were fixed in formalin, decalcified and embedded in paraffin. Staining was done with hematoxylin and examination was by a light microscope. Atrophy of synoviocytes, fibrosis of the layer underlying the synovium, dilatation, proliferation of the synovium at the cartilage-synovium migration area and congestion of the microvasculature were observed in the contracture group. The stretch group returned to almost normal conditions, but the non-stretch group to a lesser extent. The fibroconnective tissue of the contracture group was denser than that of any other group, and the stretch group improved more than the nonstretch group. However, fibrosis of the stretch group was denser than that of the control group. The surface layer of the articular cartilage in the contracture group showed fibrous proliferation in contrast to that of the control group. The contracture group showed thinner connective tissue between the muscle fibers than any other group. The stretch group improved more than the nonstretch group; on the other hand the connective tissue of the stretch group was thinner than that of the control group. Histopathological changes in the joint components showing contracture were considered to be secondary disorders caused by the cast fixation in this study. However, the stretch group improved more than the non-stretch group, suggesting that stretching has a beneficial effect on joint contracture.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学大学院医学系研究科機能障害学","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本理学療法士協会"}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110003994136/","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"本文データは日本理学療法士協会の許諾に基づきCiNiiから複製したものである"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA11545224","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-3770","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":"武村, 啓住"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"細, 正博"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"由久保, 弘明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松崎, 太郎"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"小島, 聖"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"渡邊, 晶規"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"立野, 勝彦"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"ME-PR-HOSO-M-76.pdf","filesize":[{"value":"4.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ME-PR-HOSO-M-76.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/13004/files/ME-PR-HOSO-M-76.pdf"},"version_id":"48a0c7fe-5e26-4e9c-b3de-ab3b3e593c2f"}]},"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":"ラット膝関節2週固定後の拘縮に対するストレッチが関節構成体に及ぼす病理組織学的影響(2002年度研究助成論文)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ラット膝関節2週固定後の拘縮に対するストレッチが関節構成体に及ぼす病理組織学的影響(2002年度研究助成論文)"},{"subitem_title":"Histopathological Effects of the Stretching on Joint Components after Two-week Knee Joint Immobilization in Rats(Articles Supported by Grants from JPTA)","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["1134"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"13004","relation_version_is_last":true,"title":["ラット膝関節2週固定後の拘縮に対するストレッチが関節構成体に及ぼす病理組織学的影響(2002年度研究助成論文)"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T01:11:41.826494+00:00"}
