Our objective was to characterize the cholinergic pathway in several artery vessels of the I. conceptionis. Afferent and efferent branchial, dorsal and mesenteric arteries were dissected of 6 juvenile specimens, isometric tension studies were done using doses response curves (DRC) for Ach (10\u201313 to 10\u20133 M), and cholinergic pathways were obtained by blocking with atropine or indomethacin. CRC to ACh showed a pattern of high sensitivity only in efferente branchial artery and low sensibility in all vessels. Furthermore, these contractions were blocked in the presence of atropine and indomethacin in all vessels. Our results corroborate previous results observed in intertidal species that contraction induced by acetylcholine is mediated by receptors that activate a cyclooxygenase contraction pathway.<\/jats:p>","DOI":"10.1590\/1519-6984.13413","type":"journal-article","created":{"date-parts":[[2015,6,24]],"date-time":"2015-06-24T23:27:22Z","timestamp":1435188442000},"page":"362-367","source":"Crossref","is-referenced-by-count":2,"title":["Acetylcholine produces contraction mediated by cyclooxigenase pathway in arterial vessels in the marine fish (Isacia conceptionis)"],"prefix":"10.1590","volume":"75","author":[{"given":"FA.","family":"Moraga","sequence":"first","affiliation":[{"name":"Universidad Cat\u00f3lica del Norte, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N.","family":"Urriola-Urriola","sequence":"additional","affiliation":[{"name":"Universidad Cat\u00f3lica del Norte, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"issue":"3","key":"ref1","doi-asserted-by":"crossref","first-page":"319","DOI":"10.1016\/0163-7258(93)90027-B","article-title":"Muscarinic receptors\u2014characterization, coupling and function","volume":"58","author":"Caulfield MP","year":"1993","journal-title":"Pharmacology & Therapeutics"},{"issue":"1","key":"ref2","doi-asserted-by":"crossref","first-page":"R141","DOI":"10.1152\/ajpregu.90507.2008","article-title":"Effects of carbon monoxide on trout and lamprey vessels","volume":"296","author":"Dombkowski RA","year":"2009","journal-title":"American Journal of Physiology.
