A next-generation bone cement having bone-bonding ability, i.e., bioactivity and antibacterial property is desired. We previously revealed that PMMA cement added with 2-(tert-butylamino)ethyl methacrylate, γ-methacryloxypropyltrimethoxysilane and calcium acetate showed in vitro bioactivity and antibacterial activity. This cement contains calcium acetate at 20% of the powder component. Lower content of the calcium acetate is preferable, because the release of a lot of calcium salt may degrade mechanical properties in the body environment. In the present study, we investigate the effects of calcium acetate content on the setting property and mechanical strength of the cement and apatite formation in simulated body fluid (SBF). The setting time increased and the compressive strength decreased with an increase in calcium acetate content. Although the compressive strength decreased after immersion in SBF for 7 d, all the cements still satisfied the requirements of ISO5833. Apatite was formed in SBF within 7 d on the samples where the calcium acetate content was 5% or more. Therefore, it was found that PMMA cement having antibacterial properties and bioactivity can be obtained even if the amount of the calcium acetate is reduced to 5%.","subitem_description_type":"Abstract"}]},"item_21_description_60":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Journal Article","subitem_description_type":"Other"}]},"item_21_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"28504","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Wang,  H."}]},{"affiliations":[{"affiliationNames":[{"affiliationName":"","lang":"ja"}],"nameIdentifiers":[]}],"familyNames":[{"familyName":"Maeda","familyNameLang":"en"},{"familyName":"前田","familyNameLang":"ja"},{"familyName":"マエダ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Toshinari","givenNameLang":"en"},{"givenName":"憲成","givenNameLang":"ja"},{"givenName":"トシナリ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"649","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"00470592","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000000470592"},{"nameIdentifier":"57212755607","nameIdentifierScheme":"Scopus著者ID","nameIdentifierURI":"https://www.scopus.com/authid/detail.uri?authorId=57212755607"},{"nameIdentifier":"333","nameIdentifierScheme":"九工大研究者情報","nameIdentifierURI":"https://hyokadb02.jimu.kyutech.ac.jp/html/333_ja.html"}],"names":[{"name":"Maeda, Toshinari","nameLang":"en"},{"name":"前田, 憲成","nameLang":"ja"},{"name":"マエダ, トシナリ","nameLang":"ja-Kana"}]},{"affiliations":[{"affiliationNames":[{"affiliationName":"","lang":"ja"}],"nameIdentifiers":[]}],"familyNames":[{"familyName":"Miyazaki","familyNameLang":"en"},{"familyName":"宮崎","familyNameLang":"ja"},{"familyName":"ミヤザキ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Toshiki","givenNameLang":"en"},{"givenName":"敏樹","givenNameLang":"ja"},{"givenName":"トシキ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"6369","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"20324973","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000020324973"},{"nameIdentifier":"7404107414","nameIdentifierScheme":"Scopus著者ID","nameIdentifierURI":"https://www.scopus.com/authid/detail.uri?authorId=7404107414"},{"nameIdentifier":"0000-0001-5642-0096","nameIdentifierScheme":"ORCiD","nameIdentifierURI":"https://orcid.org/0000-0001-5642-0096"},{"nameIdentifier":"323","nameIdentifierScheme":"九工大研究者情報","nameIdentifierURI":"https://hyokadb02.jimu.kyutech.ac.jp/html/323_ja.html"}],"names":[{"name":"Miyazaki, Toshiki","nameLang":"en"},{"name":"宮崎, 敏樹","nameLang":"ja"},{"name":"ミヤザキ, トシキ","nameLang":"ja-Kana"}]}]},"item_21_link_62":{"attribute_name":"研究者情報","attribute_value_mlt":[{"subitem_link_url":"https://hyokadb02.jimu.kyutech.ac.jp/html/323_ja.html"}]},"item_21_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"MDPI"}]},"item_21_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3390/ma13214998","subitem_relation_type_select":"DOI"}}]},"item_21_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (c) 2020 by the authors.
