After normal-calcium diet, calcium transport was impaired by uremia in the duodenum but not in the ileum. However, 5\/6-nephrectomized rats on low-calcium diet showed, in concert with impaired growth, a reduced calcium transport both in duodenum and ileum. Comparing data after normal- and low-calcium diets, the ileal adaptation to low-calcium diet was intact in mild renal failure but abolished in severe uremia (urea less than 100 mg\/dl). These results suggest that ileal calcium transport after normal-calcium diet is mainly passive. Taking into account reduced food intake as an additional factor, the active ileal calcium transport after low-calcium diet declines with progressive renal failure according to decreasing levels of 1,25-dihydroxyvitamin D3. A suspected enhancement of the distal small intestinal calcium transport by parathyroid hormone in uremic rats as compensation for proximally impaired absorption could not be demonstrated. <\/jats:p>","DOI":"10.1152\/ajpgi.1982.242.2.g128","type":"journal-article","created":{"date-parts":[[2017,12,23]],"date-time":"2017-12-23T23:36:04Z","timestamp":1514072164000},"page":"G128-G134","source":"Crossref","is-referenced-by-count":0,"title":["Calcium transport in the ileum of uremic rats"],"prefix":"10.1152","volume":"242","author":[{"given":"M.","family":"Koller","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"U.","family":"Binswanger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"24","container-title":["American Journal of Physiology-Gastrointestinal and Liver Physiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.physiology.org\/doi\/pdf\/10.1152\/ajpgi.1982.242.2.G128","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,9,8]],"date-time":"2019-09-08T22:15:34Z","timestamp":1567980934000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.physiology.org\/doi\/10.1152\/ajpgi.1982.242.2.G128"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1982,2,1]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[1982,2,1]]}},"alternative-id":["10.1152\/ajpgi.1982.242.2.G128"],"URL":"https:\/\/doi.org\/10.1152\/ajpgi.1982.242.2.g128","relation":{},"ISSN":["0193-1857","1522-1547"],"issn-type":[{"value":"0193-1857","type":"print"},{"value":"1522-1547","type":"electronic"}],"subject":[],"published":{"date-parts":[[1982,2,1]]}}}
