Using beagle dogs, we investigated the distribution of ghrelin in the stomach and its possible role.<\/jats:p>\n      <jats:p><jats:italic>Methods<\/jats:italic>: We examined: (i) GH release in response to ghrelin injection (0.5 or 5 \u03bcg\/kg, i.v.), (ii) gastric localization of ghrelin-immunostained cells, (iii) changes in daily food consumption after ghrelin injection (3, 10, and 20 \u03bcg\/kg, i.v.), (iv) plasma ghrelin levels under regular, but restricted feeding conditions, and (v) variations in plasma ghrelin levels in relatively lean, normal and obese dogs.<\/jats:p>\n      <jats:p><jats:italic>Results<\/jats:italic>: Administration of ghrelin to dogs promptly increased circulating GH concentrations, although this effect was transitory and was maintained for only 20 min. Ghrelin was localized in the stomach fundus and body, but none was detected in either the pylorus or cardia. Administration of ghrelin at a dose of 20 \u03bcg\/kg increased the daily food intake of beagle dogs. Plasma ghrelin levels peaked just before meal times, and then returned to basal levels. Obese dogs had higher plasma ghrelin levels than did normal and lean dogs.<\/jats:p>\n      <jats:p><jats:italic>Conclusions<\/jats:italic>: These results indicate that ghrelin is a potent GH secretagog in dogs. The distribution of ghrelin-immunoreactive cells in the canine stomach resembles that of both the murine and human stomach. Ghrelin participates in the control of feeding behavior and energy homeostasis in dogs and may, therefore, be involved in the development of obesity.<\/jats:p>","DOI":"10.1530\/eje.1.01818","type":"journal-article","created":{"date-parts":[[2005,1,24]],"date-time":"2005-01-24T21:27:42Z","timestamp":1106602062000},"page":"155-160","update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-1","source":"Crossref","is-referenced-by-count":21,"title":["Influencing the between-feeding and endocrine responses of plasma ghrelin in healthy dogs"],"prefix":"10.1093","volume":"152","author":[{"given":"Masayuki","family":"Yokoyama","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keiko","family":"Nakahara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masayasu","family":"Kojima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Hosoda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenji","family":"Kangawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Noboru","family":"Murakami","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","reference":[{"issue":"6762","key":"1_6403635","doi-asserted-by":"publisher","first-page":"656","DOI":"10.1038\/45230","volume":"402","author":"Kojima","year":"1999","journal-title":"Nature;
