In glioma cases, the brain microvessels, glial component, and neurons were isolated from the cortex by the methods of Brendel, et al., and Nagata, et al. In each sample, Na^+-K^+ATP<ase> activity was measured in the presence of various K^+ ion concentrations. In 8 glioma cases, the lowest value was obtained in the glioblastoma multiforme. Decrease in Na^+-K^+ATPase activity in the tumor or in the surrounding tissue was roughly proportional to the pathological malignancy of the tumor. In 2 cases of glioma with an epileptic focus shown by electroencephalography, activity of the enzyme was decreased in the epileptic cortex. In one case of glioma without epileptic focus, decrease of the enzyme activity was mainly attributed to decrease in the glial component. The kinetic parameters, maximum velocity (Vmax) and activation constant for K^+ (Ka) were also calculated in each sample to determine the effect of the K^+ ion on the Na^+-K^+ATPase activity. Vmax in the tumor region was significantly decreased compared with the surrounding tissue. On the other hand, differences in Ka were not so significant. Disturbed buffering action for the extracellular K^+ ions observed in the glioma group might result in lowered ability to maintain the electrolytic milieu, and might play a, significant role in the development of the epileptic focus.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Neurologia medico-chirurgica, 26(2), pp.122-126; 1986","subitem_description_type":"Other"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"58660","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Miyake, Hitoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"58661","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kurihara, Masaki"}]},{"nameIdentifiers":[{"nameIdentifier":"58662","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kawano, Teruaki"}]},{"nameIdentifiers":[{"nameIdentifier":"58663","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Mori, Kazuo"}]}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本脳神経外科学会"}]},"item_2_relation_42":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://ci.nii.ac.jp/naid/110002279595/"}]}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本脳神経外科学会"},{"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":"AN00358613","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"04708105","subitem_source_identifier_type":"ISSN"}]},"item_2_text_62":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"The Japan Neurosurgical Society"}]},"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":"三宅, 仁志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"栗原, 正紀"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"河野, 輝昭"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森, 和夫"}],"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":"110002279595.pdf","filesize":[{"value":"422.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"110002279595.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/15740/files/110002279595.pdf"},"version_id":"59b7d865-1481-460f-8a0f-dfd4e472aa48"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"brain neoplasms","subitem_subject_scheme":"Other"},{"subitem_subject":"Na^+-K^+ATPase","subitem_subject_scheme":"Other"},{"subitem_subject":"glia","subitem_subject_scheme":"Other"},{"subitem_subject":"epileptogenesis","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"ヒト脳腫瘍におけるNa^+-K^+ATPase活性の検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ヒト脳腫瘍におけるNa^+-K^+ATPase活性の検討"}]},"item_type_id":"2","owner":"2","path":["30"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-08-27"},"publish_date":"2010-08-27","publish_status":"0","recid":"15740","relation_version_is_last":true,"title":["ヒト脳腫瘍におけるNa^+-K^+ATPase活性の検討"],"weko_creator_id":"2","weko_shared_id":2},"updated":"2023-05-15T19:14:37.269128+00:00"}
