This report describes the effects of the cholecystokinin<jats:sub>2<\/jats:sub> (CCK<jats:sub>2<\/jats:sub>) receptor antagonists YM022 and YF476 on various growth parameters in the gastrointestinal tract and pancreas of the rat. YM022 and YF476 were given subcutaneously in doses known to produce maximum and sustained CCK<jats:sub>2<\/jats:sub> receptor blockade. The body weight was not affected. However, the oxyntic mucosal weight, thickness and protein and DNA contents were reduced by 15\u201320% already within 1\u20132 days and by about 30% after 4\u20138 weeks of CCK<jats:sub>2<\/jats:sub> receptor blockade. Hence, the response of the oxyntic mucosa to CCK<jats:sub>2<\/jats:sub> receptor blockade was in the form of hypotrophy (reduced protein content) and hypoplasia (reduced DNA content). There were no obvious effects of CCK<jats:sub>2<\/jats:sub> receptor blockade on the intestine or pancreas (nor on liver, kidney or thyroid). The proton pump inhibitor omeprazole was used to induce hypergastrinaemia and was given with or without YM022. Omeprazole treatment for 4 weeks increased the oxyntic mucosal weight and thickness by 15\u201320%. YM022 prevented these effects. We conclude that while elevated circulating gastrin levels, acting on CCK<jats:sub>2<\/jats:sub> receptors, exert a growth\u2010promoting effect on the oxyntic mucosa (but not elsewhere), normal serum gastrin levels exert a mucosa\u2010preserving effect.<\/jats:p>","DOI":"10.1111\/j.0901-9928.2001.890411.x","type":"journal-article","created":{"date-parts":[[2004,9,28]],"date-time":"2004-09-28T13:02:04Z","timestamp":1096376524000},"page":"208-213","source":"Crossref","is-referenced-by-count":6,"title":["Effects of CCK<sub>2<\/sub> Receptor Blockade on Growth Parameters in Gastrointestinal Tract and Pancreas in Rats"],"prefix":"10.1111","volume":"89","author":[{"given":"Maria","family":"Bj\u00f6rkqvist","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Per","family":"Norl\u00e9n","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masayuki","family":"Kitano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Duan","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chun\u2010Mei","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charlotta","family":"Dornonville de la Cour","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rebecca","family":"Gagnemo\u2010Persson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rolf","family":"H\u00e5kanson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,9,28]]},"container-title":["Pharmacology &amp; Toxicology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.0901-9928.2001.890411.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/j.0901-9928.2001.890411.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,18]],"date-time":"2023-11-18T11:34:46Z","timestamp":1700307286000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.0901-9928.2001.890411.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2001,10]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2001,10]]}},"alternative-id":["10.1111\/j.0901-9928.2001.890411.x"],"URL":"https:\/\/doi.org\/10.1111\/j.0901-9928.2001.890411.x","archive":["Portico"],"relation":{},"ISSN":["0901-9928"],"issn-type":[{"value":"0901-9928","type":"print"}],"subject":[],"published":{"date-parts":[[2001,10]]}}}
