METHODS: In isolated rat trachea, isometric force was recorded to examine the effects of amitriptyline on the contractile response to acetylcholine (ACh), electrical field stimulation (EFS), calyculin A (a myosin light chain phosphatase inhibitor), and sphingosylphosphorylcholine (SPC; a Rhokinase activator). In addition, inositol monophosphate (IP1) accumulation was measured to examine its effects on inositol 1, 4, 5-trisphosphate (IP(3)) production during stimulation with ACh. RESULTS: Amitriptyline inhibited the contractile responses to ACh, EFS, calyculin A, and SPC, with the concentrations of amitriptyline (mean +/- SD) required to exert 50% inhibition (IC(50)) being 4.3 +/- 1.3 microM, 3.2 +/- 1.6 microM, 256.4 +/- 106.4 microM, and 98.2 +/- 21.8 microM, respectively. In addition, amitriptyline (10 microM) eliminated the ACh (10 microM)-induced IP(1) accumulation. CONCLUSION: The results suggest that amitriptyline does not influence tracheal smooth muscle reactivity at clinical concentrations (<1 microM), but attenuates the reactivity at supraclinical concentrations (> or =1 microM). The attenuated response to ACh brought about by amitriptyline is presumably due, at least in part, to the inhibition of phosphatidylinositol (PI) metabolism. The ability of amitriptyline to inhibit the calyculin Ainduced contraction suggests that amitriptyline also inhibits the Ca(2+)-calmodulin-myosin light chain pathway independently of the inhibition of PI metabolism. Finally, the difference between the IC(50) values for SPC-induced contraction and those for calyculin A-induced contraction suggests that amitriptyline may also inhibit the Rho-kinase pathway.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Journal of anesthesia, 23(3), pp.385-391; 2009","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Japan"}]},"item_2_relation_11":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"19685119","subitem_relation_type_select":"PMID"}}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s00540-009-0781-0","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c Japanese Society of Anesthesiologists 2009."},{"subitem_rights":"The original publication is available at www.springerlink.com"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10852931","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09138668","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"14388359","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Matsunaga, Shoji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shibata, Osamu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nishioka, Kenji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tsuda, Atsushi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Makita, Tetsuji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sumikawa, Koji"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"JourAne23_385.pdf","filesize":[{"value":"267.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JourAne23_385.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/16883/files/JourAne23_385.pdf"},"version_id":"1f5a5bae-29ac-405e-a9dd-cca3e4c54150"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Airwaysmooth muscle","subitem_subject_scheme":"Other"},{"subitem_subject":"Amitriptyline","subitem_subject_scheme":"Other"},{"subitem_subject":"Contractile response","subitem_subject_scheme":"Other"},{"subitem_subject":"Phosphatidylinositol response","subitem_subject_scheme":"Other"},{"subitem_subject":"Rats","subitem_subject_scheme":"Other"},{"subitem_subject":"Rho-kinase pathway","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":"Effects of amitriptyline, a tricyclic antidepressant, on smooth muscle reactivity in isolated rat trachea.","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effects of amitriptyline, a tricyclic antidepressant, on smooth muscle reactivity in isolated rat trachea."}]},"item_type_id":"2","owner":"2","path":["9"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-09-01"},"publish_date":"2010-09-01","publish_status":"0","recid":"16883","relation_version_is_last":true,"title":["Effects of amitriptyline, a tricyclic antidepressant, on smooth muscle reactivity in isolated rat trachea."],"weko_creator_id":"2","weko_shared_id":2},"updated":"2023-05-15T19:24:00.432874+00:00"}
