HE cells were cultured in an incubator that was set in a ^<60>Co γ-ray-irradiation room, and the irradiation was repeated throughout the life-span of the HE cells (for about 150 to 160 days) on every day base. During this period, the cells accumulated 106 to 123 cGy. The life-span of the irradiated cells prolonged 1.14 to 1.35 times when compared to that of non-irradiated cells. The incidence of cells with chromosome bridge and micronuclei significantly increased in the irradiated cells. Although the number of chromosomes gradually changed with repetition of culture in both non-irradiated and irradiated cells, the frequencies of aneuploid cells in irradiated cells were about two times higher than that in non-irradiated cells. These results indicate that repeated irradiation with a low dose of γ-rays produces chromosome instability, and it may be a cause of numerical chromosome abnormalities and life-span extension of irradiated cells.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Journal of radiation research. 1998, 39(3), p.203-213","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本放射線影響学会"}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本放射線影響学会"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00705792","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"04493060","subitem_source_identifier_type":"ISSN"}]},"item_2_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":"Suzuki, Masao"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yang, Zhi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakano, Kazushiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yatagai, Fumio"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Suzuki, Keiji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kodama, Seiji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Watanabe, Masami"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"RR39_3_203_213.pdf","filesize":[{"value":"536.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"RR39_3_203_213.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/19695/files/RR39_3_203_213.pdf"},"version_id":"ae6e19ee-ab01-400f-9ba4-3839e9afdca3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Low dose γ-rays","subitem_subject_scheme":"Other"},{"subitem_subject":"Life-span extension","subitem_subject_scheme":"Other"},{"subitem_subject":"Chromosome bridge","subitem_subject_scheme":"Other"},{"subitem_subject":"Chromosome instability","subitem_subject_scheme":"Other"},{"subitem_subject":"Human embryo cells","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Extension of In vitro Life-span of γ-irradiated Human Embryo Cells Accompanied by Chromosome Instability","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Extension of In vitro Life-span of γ-irradiated Human Embryo Cells Accompanied by Chromosome Instability"}]},"item_type_id":"2","owner":"2","path":["11"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-08-12"},"publish_date":"2008-08-12","publish_status":"0","recid":"19695","relation_version_is_last":true,"title":["Extension of In vitro Life-span of γ-irradiated Human Embryo Cells Accompanied by Chromosome Instability"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T03:06:54.525882+00:00"}
