This study investigated the maturation of the heart rate (HR) and the autonomic regulation of HR responses to restraint stress during the first 2 postnatal weeks in rats.　Autonomic blockade with atropine, metoprolol, and dual atropine/metoprolol blockade (2 mg/kg) at postnatal day (P) 4 and P12 demonstrated predominantly sympathetic effects on baseline HR. From birth to P9, rats restrained by electrocardiography electrodes for 5 min displayed slow cardiodeceleration, which changed into transient bradycardia (TB) during P9-14. Interestingly, this TB was abolished by autonomic blockade on P12 ; stable tachycardia (18% increase) and unstable HR were observed under parasympathetic and sympathetic blockade, respectively. In addition, HR under dual blockade increased by 25% (p=0.009) after the animals were restrained but not under dual blockade with a 10-fold higher dose. These results suggest that TB is mediated by a complex sympathetic-parasympathetic interaction, which is immature during the vulnerable period and can potentially cause life-threatening cardiac events.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"秋田医学会"}]},"item_10001_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00009294","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03866106","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"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":"Tokunaga, Jun"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sato, Shinichi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kanbayashi, Takashi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Imanishi, Aya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sagawa, Yohei"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sato, Masatoshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sakai, Noriaki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nishino, Seiji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shimizu, Tetsuo"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-16"}],"displaytype":"detail","filename":"akitai40-2(89).pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"akitai40-2(89).pdf","url":"https://air.repo.nii.ac.jp/record/2156/files/akitai40-2(89).pdf"},"version_id":"155a8f67-0a5b-4f57-b960-661cfeae1206"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"newborn rats","subitem_subject_scheme":"Other"},{"subitem_subject":"heart rate","subitem_subject_scheme":"Other"},{"subitem_subject":"restraint stress","subitem_subject_scheme":"Other"},{"subitem_subject":"accentuated antagonism","subitem_subject_scheme":"Other"},{"subitem_subject":"sudden infant death syndrome","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":"SYMPATHETIC AND PARASYMPATHETIC CONTROL OF HEART RATE RESPONSE TO RESTRAINT STRESS DURING THE VULNERABLE PERIOD IN NEWBORN RATS","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"SYMPATHETIC AND PARASYMPATHETIC CONTROL OF HEART RATE RESPONSE TO RESTRAINT STRESS DURING THE VULNERABLE PERIOD IN NEWBORN RATS"}]},"item_type_id":"10001","owner":"3","path":["976"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-01-07"},"publish_date":"2014-01-07","publish_status":"0","recid":"2156","relation_version_is_last":true,"title":["SYMPATHETIC AND PARASYMPATHETIC CONTROL OF HEART RATE RESPONSE TO RESTRAINT STRESS DURING THE VULNERABLE PERIOD IN NEWBORN RATS"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-25T11:33:15.318768+00:00"}
