These F-actin bands were seen typically in 7-day-old rats. 82.8% of F-actin bands was ring-formed type and 17.2% of F-actin bands was arch- or line-formed type.2. The cytoplasm of cells were doubly stained with FITC-phalloidin and a rat monoclonal antibody, ED1,indicating that F-actin bands stained with FITC-phalloidin were the clear zone of osteoclasts.3.To clarify the relation between the form of F-actin bands and the bone resorbing activity of osteoclasts, the effects of calcitonin (CT) and parathyroid hormone (PTH) were examined in 7-day-old rats. At 30 min after injection of CT (salmon, 0.1 pg/10 g), F-actin bands changed from ring-formed bands to arch- or line-formed bands. F-actin bands were scarcely found in osteoclasts after lh and the number of F-actin bands recovered to normal level after 6h of CT injection. After injection of PTH (bovine, 0.5 pg/10 g), the number of ring-formed F-actin bands did not change significantly, while the increased intensity of fluorescence was seen in the ring-formed bands. These results suggested that the osteoclasts with ring-formed F-actin bands actively resorb bone and the osteoclasts with arch- or line-formed F-actin bands less actively resorb bone.4.The observation of whole mount specimens of calvariae might be useful to examine the effects of factors affecting activities of osteoclasts in vivo.","subitem_description_type":"Abstract"}]},"item_4_description_41":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"紀要類(bulletin)","subitem_description_type":"Other"}]},"item_4_description_66":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"1114362 bytes","subitem_description_type":"Other"}]},"item_4_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"56124","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kuroda, Hiroshi"}]}]},"item_4_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東北大学歯学会"}]},"item_4_radio_69":{"attribute_name":"公開範囲","attribute_value_mlt":[{"subitem_radio_item":"学外"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02873915","subitem_source_identifier_type":"ISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00081101","subitem_source_identifier_type":"NCID"}]},"item_4_version_type_16":{"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":"黒田, 洋史"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-10"}],"displaytype":"detail","filename":"KJ00000093440.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000093440.pdf","url":"https://tohoku.repo.nii.ac.jp/record/23415/files/KJ00000093440.pdf"},"version_id":"42103ddb-2c86-4cf1-b873-dadb09cfe598"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Osteoclasts","subitem_subject_scheme":"Other"},{"subitem_subject":"Bone resorption","subitem_subject_scheme":"Other"},{"subitem_subject":"F-actin bands","subitem_subject_scheme":"Other"},{"subitem_subject":"rat calvariae","subitem_subject_scheme":"Other"},{"subitem_subject":"CT and PTH","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":"In vivoにおける破骨細胞F-アクチン帯の形態及びそのカルシトニン(CT)と副甲状腺ホルモン(PTH)による影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"In vivoにおける破骨細胞F-アクチン帯の形態及びそのカルシトニン(CT)と副甲状腺ホルモン(PTH)による影響"}]},"item_type_id":"4","owner":"3","path":["178"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-05-02"},"publish_date":"2008-05-02","publish_status":"0","recid":"23415","relation_version_is_last":true,"title":["In vivoにおける破骨細胞F-アクチン帯の形態及びそのカルシトニン(CT)と副甲状腺ホルモン(PTH)による影響"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T16:27:37.280493+00:00"}
