Extracellular potassium ([K+]e) and extracellular calcium ([Ca++]e) showed a triphasic change during ischemia followed by a biphasic change after recirculation. The EEG became flat within about 20 seconds. There was a sharp increase in the [K+]e and a sharp decrease in the [Ca++]e, which coincided with the sharp increase in the Fp around one and a half minutes. The impedance increased simultaneously with a large amplitude change of EEG. The [Ca++]e continued to decrease for another 1-2 minutes before returning to the normal values after recirculation whereas the [K+]e began to decrease immediately. The extracellular space (ECS) did not change until depolarization. The rise of the [K+]e and [Ca++]e in the pre-depolarization phase was not explained by the shrinkage of the ECS. The possible explanation for the change of the [Ca++]e in ischemia was discussed.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Tokyo Medical and Dental University"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.11480/btmd.330101","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2435-0761","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Takekane, YAMAGUCHI"}],"nameIdentifiers":[{"nameIdentifier":"4646","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takekane, YAMAGUCHI","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"4647","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":"2019-09-26"}],"displaytype":"detail","filename":"01_Yamaguchi.pdf","filesize":[{"value":"2.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"01_Yamaguchi.pdf","url":"https://tmdu.repo.nii.ac.jp/record/538/files/01_Yamaguchi.pdf"},"version_id":"5418196d-26e5-4cfe-a9f9-811529bd0984"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Cerebral ischemia","subitem_subject_scheme":"Other"},{"subitem_subject":"extracellular ion concentration","subitem_subject_scheme":"Other"},{"subitem_subject":"cerebral impedance","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":"CEREBRAL EXTRACELLULAR POTASSIUM CONCENTRATION CHANGE AND CEREBRAL IMPEDANCE CHANGE IN SHORT-TERM ISCHEMIA IN GERBIL","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"CEREBRAL EXTRACELLULAR POTASSIUM CONCENTRATION CHANGE AND CEREBRAL IMPEDANCE CHANGE IN SHORT-TERM ISCHEMIA IN GERBIL"}]},"item_type_id":"10001","owner":"3","path":["186"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-09-26"},"publish_date":"2019-09-26","publish_status":"0","recid":"538","relation_version_is_last":true,"title":["CEREBRAL EXTRACELLULAR POTASSIUM CONCENTRATION CHANGE AND CEREBRAL IMPEDANCE CHANGE IN SHORT-TERM ISCHEMIA IN GERBIL"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2024-03-06T07:42:02.404431+00:00"}
