Series of experiments were performed on each rabbit, once before and five times after the operation of PO/AH lesions, and thermoregulatory ability in recovering process was investigated in rabbits with PO/AH lesions. (1) The body weights significantly decreased after PO/AH operation. But food intake (g/day) recovered to normal level at the 7th day after PO/AH operation and the body weights were over the preoperational level at the 18th day after PO/AH operation. (2) The PO/AH lesion caused marked impairment of abilities in heat loss responses such as vasodilation and thermal panting which lasted for 7 days after surgical operation. Therefore, general hyperthermia was successively induced, and rectal temperature (Tre) increased significantly in heat exposure. (3) Heat loss ability gradually recovered to the normal level by the 28th day after PO/AH operation, and Tre was controlled within normal range when the animal was exposed to heat exposure. (4) On the other hand, PO/AH lesion caused scarcely any disturbance of heat conservative function such as vasoconstriction. Therefore, no significant decrease in Tre was observed in PO/AH lesion rabbits, even in cold exposure. These results suggest that extra PO/AH thermosensitive tissues in the posterior hypothalamus, midbrain reticular formation, medulla oblongata and spinal cord may join to play an important role of thermoregulation to general thermal stimulation within 28 days after bilateral PO/AH destruction in rabbits.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"熱帯医学 Tropical medicine 28(3). p225-240, 1986","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"106379","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ohwatari, Nobu"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学熱帯医学研究所"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00199644","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03855643","subitem_source_identifier_type":"ISSN"}]},"item_3_text_62":{"attribute_name":"sortkey","attribute_value_mlt":[{"subitem_text_value":"P00225-P00240"}]},"item_3_text_63":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"Institute of Tropical Medicine, Nagasaki University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大渡, 伸"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-24"}],"displaytype":"detail","filename":"tm28_03_08_t.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"tm28_03_08_t.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/25080/files/tm28_03_08_t.pdf"},"version_id":"35dfc28a-b9a8-48e5-bf9f-a0c0e2940dc0"}]},"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":"慢性視床下部障害ウサギの体温調節能の回復過程に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"慢性視床下部障害ウサギの体温調節能の回復過程に関する研究"}]},"item_type_id":"3","owner":"2","path":["1853"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-04-26"},"publish_date":"2006-04-26","publish_status":"0","recid":"25080","relation_version_is_last":true,"title":["慢性視床下部障害ウサギの体温調節能の回復過程に関する研究"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-15T23:50:49.074593+00:00"}
