Cells were exposed to Co60 gamma-rays at 6 doses of 10, 15, 20, 40, 100 and 200 Gy for water, and also to 290 MeV/amu carbon ions from the Heavy Ion Medical Accelerator in Chiba at 7 doses (5, 10, 15, 20, 50, 100 and 200 Gy for water). The swimming velocity was measured by a biomonitoring system, called ECOTOX. The swimming velocities of Euglena gracilis cells were significantly decreased by >40 Gy gamma-rays and >5 Gy carbon ions, respectively. The 50% effective doses for inhibitaion, 34+-4 Gy (gamma-rays) and 13+-1 Gy (290 MeV/amu carbon ions), were estimated from the best fit to data of the logistic model. The relative biological effectiveness (2.6+-0.4) was calculated by the ratio of 50% effective doses. The inhibitation of the swimming velocity of the cells irradiated with gamma-rays was still present after 3 days, while recovery of the cells irradiated with shown in the cells exposed to 290 MeV/amu carbon ions. It is suggested that ionizing radiation inhibits ATP production and/or increases frictional drag on beating of the flagellum, thus decreasing swimming velocity.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0273-1177","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sakashita, Tetsuya"}],"nameIdentifiers":[{"nameIdentifier":"429830","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Doi, Masahiro"}],"nameIdentifiers":[{"nameIdentifier":"429831","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasuda, Hiroshi"}],"nameIdentifiers":[{"nameIdentifier":"429832","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fuma, Shoichi"}],"nameIdentifiers":[{"nameIdentifier":"429833","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"P., Haeder Donat"}],"nameIdentifiers":[{"nameIdentifier":"429834","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"坂下 哲哉","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"429835","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"土居 雅広","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"429836","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"保田 浩志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"429837","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"府馬 正一","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"429838","nameIdentifierScheme":"WEKO"}]}]},"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":"Effects of gamma-ray and high energy carbon ion irradiation on swimming velocity of Euglena gracilis.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effects of gamma-ray and high energy carbon ion irradiation on swimming velocity of Euglena gracilis."}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2003-10-20"},"publish_date":"2003-10-20","publish_status":"0","recid":"43207","relation_version_is_last":true,"title":["Effects of gamma-ray and high energy carbon ion irradiation on swimming velocity of Euglena gracilis."],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:30:01.300741+00:00"}
