title: Stimulation of calcium absorption and apparent increased intestinal 1,25-dihydroxycholecalciferol in rats treated with low doses of ethane-1-hydroxy-1,1-diphosphonate.
abstract: 1. Ligated intestinal segments from rats treated with disodium ethane-1-hydroxy-1,1-diphosphonate (EHDP) at the daily dose of 16 mumol (identical to 1 mg of phosphorus)/kg subcutaneously for 7 days show an increased rate of calcium absorption. 2. This dose of EHDP enhances the intestinal accumulation of a vitamin D3 metabolite with the chromatographic characteristics of 1,25-dihydroxycholecalciferol.
