Objective: To determine whether oxygen consumption and production of carbon dioxide by bacteria could be a cause of negative pressure in ears with otitis media. Methods: Hermetically-sealed tubes (2ml of volume) containing 1 ml of culture media with Streptococcus pneumoniae leaving 1\nml of airspace were connected to a micro-pressure sensor, and were maintained at 37 degree centigrade in a water bath. Chronological changes of air pressure in the tube were monitored for 15 hours (bacterial group), and were compared with those in the tubes containing culture media only controls). Also, partial pressures of oxygen and carbon dioxide in the culture media of\nthose bottles were measured. Results: The pressure of the bacterial group were significantly lower than that of controls (bacterial group; -94.6±92mmH2O, control group; 4.6±11.1mmH2O, 2 way-ANOVA, P<0.001). The partial pressures of oxygen were lower (bacterial group; -86.0±22.1mmHg, control group; -34.6±7.93mmHg, 2 way-ANOVA, P<0.0001) and those of carbon dioxide were significantly\nhigher in the bacterial group than in the control group (bacterial group; 11.8±3.8mmHg, control group; -0.23±0.41mmHg, 2 way-ANOVA, P<0.0001).","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Acta medica Nagasakiensia, 60(4), pp.141-144; 2016","subitem_description_type":"Other"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Nagasaki University School of Medicine"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00508430","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00016055","subitem_source_identifier_type":"ISSN"}]},"item_3_text_62":{"attribute_name":"sortkey","attribute_value_mlt":[{"subitem_text_value":"02"}]},"item_3_text_63":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"長崎大学医学部"}]},"item_3_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":"Kitaoka, Kyoko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takahashi, Haruo"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-21"}],"displaytype":"detail","filename":"ActMed60_141.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ActMed60_141.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/3695/files/ActMed60_141.pdf"},"version_id":"018dd841-94a7-47fe-80ef-af35d7fb7dfa"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Bacteria","subitem_subject_scheme":"Other"},{"subitem_subject":"negative middle ear pressure","subitem_subject_scheme":"Other"},{"subitem_subject":"otitis media","subitem_subject_scheme":"Other"},{"subitem_subject":"oxygen consumption","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":"Negative pressure produced by bacteria: A possible cause of negative middle ear pressure in ears with otitis media","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Negative pressure produced by bacteria: A possible cause of negative middle ear pressure in ears with otitis media"}]},"item_type_id":"3","owner":"2","path":["253"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-10-14"},"publish_date":"2016-10-14","publish_status":"0","recid":"3695","relation_version_is_last":true,"title":["Negative pressure produced by bacteria: A possible cause of negative middle ear pressure in ears with otitis media"],"weko_creator_id":"2","weko_shared_id":2},"updated":"2024-04-16T05:27:46.765554+00:00"}
