Twenty-three adult mongrel cats were divided into two groups : global (n=9) and focal ischemic (n=14) groups.　　    In the case of global ischemia, which was induced by hypovolemic hypotension due to blood letting, deterioration of the D wave began when the mean arterial blood pressure (MABP) approached 45 mmHg, and regional cerebral blood flow (rCBF) dropped to 40% of control. Complete disappearance of the D wave was observed below 30 mmHg in MABP and 20% of control in rCBF. In the case of focal ischemia, which was induced by transorbital occlusion of the middle cerebral artery, the percentages of rCBF at which the D wave disappeared ranged from 9 to 20%. Changes in the amplitude of the D wave - an increase and following decrease - preceded the prolongation of its latency.　　    In contrast with the D wave I waves were too easily affected by ischemia. Moreover, rCBF at the point of disappearance of the I wave varied greatly.　　    In conclusion, the D wave is stable in mild ischemia and is a reliable indicator of critically profound ischemia (%rCBF < 40%). Monitoring the D wave of MEPs seems to be a useful method for avoiding the deterioration of motor function by ischemic insult.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"Hiroshima University Medical Press"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0018-2052","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AA00664312","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"開始ページ","attribute_value_mlt":[{"subitem_start_page":"1"}]},"item_1617187056579":{"attribute_name":"bibliographic_information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1995-03","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicPageEnd":"5","bibliographicPageStart":"1","bibliographicVolumeNumber":"44","bibliographic_titles":[{"bibliographic_title":"Hiroshima Journal of Medical Sciences"},{"bibliographic_title":"Hiroshima Journal of Medical Sciences"}]}]},"item_1617258105262":{"attribute_name":"item_1617258105262","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"HiroshimaJMedSci_44_1.pdf","filesize":[{"value":"513.2 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2013360/files/HiroshimaJMedSci_44_1.pdf"},"version_id":"19dc2c34-7b82-4114-8c8a-b310fe02fa5c"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"37852"},"item_title":"Changes of Motor Evoked Potentials in Global and Focal Ischemic Models of Cats","item_type_id":"40003","owner":"41","path":["1730442312681"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2013360","relation_version_is_last":true,"title":["Changes of Motor Evoked Potentials in Global and Focal Ischemic Models of Cats"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-26T05:04:10.710431+00:00"}
