In-vitro C6 37% survival dose (D_<37>) were obtained at 3.55×10^<12>n/cm^2 in 500ppm ^nGd medium, 1.40×10^<12>n/cm^2 in 2,500ppm ^nGd containing medium, and 6.80×10^<12>n/cm^2 in Gd-free medium. The relative killing effect of GdNCT against control study was 1.92 fold for 500ppm ^nGd(+) and 4.86 fold for 2,500ppm Gd(+). The significant survival prolongation of 9L brain tumor rat was observed by intra-venous injection of GdDTPA. Mean survival via GdNCT was 33.5±3.0 days, and that of control rats was 16.4±0.6 days. The optimal Gd concentration was estimated less than 1,000ppm ^<157>Gd for various reasons, since neutron fluence rapidly decrease in the deeply seated tumor due to high absorption of neutron by Gd atoms. The maximum contribution of γ rays on tumor absorbed dose was less than 50%. In a spherical tumor model in diameter of 3cm, approximately 25% of absorbed dose was transferred by γ rays and more that 50% of that by internal conversion electrons. The peri-tumoral dose distribution does not decrease sharply like BNCT. The 10% decrease level was estimated to be 2-3cm from the tumor margin. This blunt dose distribution might be effective to destroy the invading tumor cells in the peri-tumoral lesion manifesting as high density area in T^2-weighted MRI.","subitem_description_type":"Other"}]},"item_3_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"7","subitem_description_type":"Other"}]},"item_3_description_16":{"attribute_name":"アクセション番号","attribute_value_mlt":[{"subitem_description":"KJ00005223106","subitem_description_type":"Other"}]},"item_3_description_2":{"attribute_name":"ページ属性","attribute_value_mlt":[{"subitem_description":"P","subitem_description_type":"Other"}]},"item_3_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Original article","subitem_description_type":"Other"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11877461","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1348480X","subitem_source_identifier_type":"ISSN"}]},"item_3_text_7":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Nursing, Aino Gakuin College:Department of Chemistry and Biochemistry, Northern Illinois University"},{"subitem_text_language":"en","subitem_text_value":"Department of Chemistry and Biochemistry, Northern Illinois University"}]},"item_3_title_3":{"attribute_name":"論文名よみ","attribute_value_mlt":[{"subitem_title":"Gadolinium neutron capture therapy for malignant brain tumors"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"TAKAGAKI, Masao","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1098","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"HOSMANE, Narayan S.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1099","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":"2019-03-27"}],"displaytype":"detail","filename":"KJ00005223106.pdf","filesize":[{"value":"964.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00005223106.pdf","url":"https://aino.repo.nii.ac.jp/record/330/files/KJ00005223106.pdf"},"version_id":"1e41486a-5404-49f2-b033-e8f149ffd286"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"neutron capture therapy","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gadolinium","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"malignant brain tumors","subitem_subject_language":"en","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Gadolinium neutron capture therapy for malignant brain tumors","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Gadolinium neutron capture therapy for malignant brain tumors","subitem_title_language":"en"}]},"item_type_id":"3","owner":"4","path":["38"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-27"},"publish_date":"2019-03-27","publish_status":"0","recid":"330","relation_version_is_last":true,"title":["Gadolinium neutron capture therapy for malignant brain tumors"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-05-15T16:08:10.661420+00:00"}
