The experiments were carried out in ten anesthetized male rabbits. Reflex swallowing was evoked by injection of distilled water into oropharyngeal region. Swallowing events recorded were divided into three types, depending on when the reflex was evoked : Early I type was defined as the one evoked before the peak of diaphragmatic burst, Late I type evoked after the peak of the diaphragmatic burst and Before I type evoked before the onset of diaphragmatic burst. About 90% of swallowing in the present study was evoked in the inspiratory phase. Respiration-related muscle activity was modulated during swallowing as well as the tracheal pressure and the modulatory pattern of them was different among the swallowing types. Particularly, the duration of positive-tracheal pressure was significantly shorter during Before I swallowing than Early I or Late I. The duration of diaphragmatic burst and tracheal positive pressure tended to be expanded during Early I and Late I swallowing as compared to before or after swallowing. Furthermore, the respiratory rate was decreased before the onset of Early I swallowing while that was not the case during Late I and Before I swallowing. The present study suggested that the peripheral inputs to the respiratory center resulted in the early modulation of respiratory-related muscle activity. However, the results that the modulation of respiratory pattern lead to the occurrence of swallowing may also suggest that the neuronal activity responsible for the initiation of swallowing changes that of the respiratory center before the onset of swallowing.","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"150066","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kitsu, Kazunori"}]},{"nameIdentifiers":[{"nameIdentifier":"150067","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Inoue, Makoto"}]}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟歯学会"}]},"item_7_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN0018300X","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03850153","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉津, 和憲"}],"nameIdentifiers":[{"nameIdentifier":"150064","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"井上, 誠"}],"nameIdentifiers":[{"nameIdentifier":"150065","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":"2019-08-19"}],"displaytype":"detail","filename":"NS_39(2)_117-121.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"NS_39(2)_117-121.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/25457/files/NS_39(2)_117-121.pdf"},"version_id":"6814cacf-7e8e-40cf-a1ef-8bc6105fad74"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"呼吸","subitem_subject_scheme":"Other"},{"subitem_subject":"嚥下","subitem_subject_scheme":"Other"},{"subitem_subject":"筋電図","subitem_subject_scheme":"Other"},{"subitem_subject":"気管内圧","subitem_subject_scheme":"Other"},{"subitem_subject":"Respiration","subitem_subject_scheme":"Other"},{"subitem_subject":"Swallowing","subitem_subject_scheme":"Other"},{"subitem_subject":"Electromyography","subitem_subject_scheme":"Other"},{"subitem_subject":"Tracheal pressure","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"嚥下反射誘発時の呼吸関連筋活動の変調","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"嚥下反射誘発時の呼吸関連筋活動の変調"},{"subitem_title":"嚥下反射誘発時の呼吸関連筋活動の変調","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1299"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-01-21"},"publish_date":"2015-01-21","publish_status":"0","recid":"25457","relation_version_is_last":true,"title":["嚥下反射誘発時の呼吸関連筋活動の変調"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:55:23.899163+00:00"}
