The aim of the present study was to determine the mechanisms underlying the antigen-induced anaphylactic responses in the rat colons. Wistar rats were sensitized by intraperitoneal injection of ovalbumin (OVA). The contractilities of isolated proximal colons of the sensitized rats were studied in the organ bath. OVA challenges of sensitized tissues induced prolonged contractile responses. The antigen-induced contractions were greatly reduced by mast cell stabilizer doxantrazole (10 μM). However, the contractions were resistant to histamine H1 receptor antagonist and prostaglandin D<SUB>2</SUB> receptor antagonist. In contrast, non-selective cyclooxygenase (COX) inhibitor indomethacin (1 μM) significantly reduced the contractions by 61.0%. Furthermore, selective COX-1 inhibitor FR122047 (10 μM) as well as selective COX-2 inhibitor NS-398 (10 μM) significantly inhibited the contractions by 50.1% and 50.3%, respectively. Nevertheless, the transcript levels of COX-2 as well as COX-1 were not upregulated by OVA in the proximal colons of the sensitized rats. The present results indicate that de novo arachidonic acid metabolites synthesis by constitutive COX-1 as well as constitutive COX-2 within mast cells contribute to the altered smooth muscle contractilities in the colons under the anaphylactic condition."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410282679876775684","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000283112665"}],"foaf:name":[{"@language":"en","@value":"KADOWAKI Hiroko"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Division of Gastrointestinal Pathophysiology, Institute of Natural Medicine, University of Toyama"},{"@language":"en","@value":"Osaka University Hospital, Department of Pharmacy"}]},{"@id":"https://cir.nii.ac.jp/crid/1420845751142735872","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"70316181"},{"@type":"NRID","@value":"1000070316181"},{"@type":"NRID","@value":"9000021918827"},{"@type":"NRID","@value":"9000022207109"},{"@type":"NRID","@value":"9000410905204"},{"@type":"NRID","@value":"9000259836450"},{"@type":"NRID","@value":"9000021109238"},{"@type":"NRID","@value":"9000410622539"},{"@type":"NRID","@value":"9000283112666"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/read0060442"}],"foaf:name":[{"@language":"en","@value":"YAMAMOTO Takeshi"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Division of Gastrointestinal Pathophysiology, Institute of Natural Medicine, University of Toyama"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282679876775683","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000283112667"}],"foaf:name":[{"@language":"en","@value":"KAGEYAMA-YAHARA Natsuko"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Division of Gastrointestinal Pathophysiology, Institute of Natural Medicine, University of Toyama"}]},{"@id":"https://cir.nii.ac.jp/crid/1030848083273185793","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"60225282"},{"@type":"NRID","@value":"1000060225282"},{"@type":"NRID","@value":"9000000697164"},{"@type":"NRID","@value":"9000008681992"},{"@type":"NRID","@value":"9000006205059"},{"@type":"NRID","@value":"9000283495760"},{"@type":"NRID","@value":"9000283495520"},{"@type":"NRID","@value":"9000001883032"},{"@type":"NRID","@value":"9000257922884"},{"@type":"NRID","@value":"9000257923245"},{"@type":"NRID","@value":"9000020410471"},{"@type":"NRID","@value":"9000283495667"},{"@type":"NRID","@value":"9000258012163"},{"@type":"NRID","@value":"9000020656970"},{"@type":"NRID","@value":"9000259847146"},{"@type":"NRID","@value":"9000283495589"},{"@type":"NRID","@value":"9000283495512"},{"@type":"NRID","@value":"9000283112668"},{"@type":"NRID","@value":"9000006490666"},{"@type":"NRID","@value":"9000021058108"},{"@type":"NRID","@value":"9000283495719"},{"@type":"NRID","@value":"9000363364598"},{"@type":"NRID","@value":"9000363366074"},{"@type":"NRID","@value":"9000363364626"},{"@type":"NRID","@value":"9000363365130"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/read0013702"}],"foaf:name":[{"@language":"en","@value":"KUROKAWA Nobuo"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Osaka University Hospital, Department of Pharmacy"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282679876775680","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000283112669"}],"foaf:name":[{"@language":"en","@value":"KADOWAKI Makoto"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Division of Gastrointestinal Pathophysiology, Institute of Natural Medicine, University of Toyama"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"03886107"},{"@type":"LISSN","@value":"03886107"},{"@type":"EISSN","@value":"1880313X"}],"prism:publicationName":[{"@language":"en","@value":"Biomedical Research"},{"@language":"en","@value":"Biomed.
