Oral calcium carbonate (0-5 g, pH 9-4) increased serum gastrin and gastric acid output with slight but insignificant change in serum calcium. A similar rise in serum calcium during an intravenous infusion of calcium gluconate failed to increase serum gastrin and gastric acid output. Both intragastric calcium actions were abolished by acidification of the calcium carbonate solution (pH 1-0). The...

This study was conducted to compare ileal digestibility of calcium, dry matter and ash, growth performance, gut characteristics, bone parameters and retention of calcium in broiler chickens fed diets containing different calcium sources. A total of 96 commercial Ross 308 broiler chickens were allocated to three experimental diets. The experimental diets included a diet containing inorganic calc...

a fundamental study of scale formation of calcium carbonate (caco3) for producing oil wells hasbeen carried out. this article presents the study of the prediction of salt deposition in two differentsynthetic formation waters and investigates the effects of temperature and pressure on calciumcarbonate precipitation. the dependence of the induction period of the precipitation of calciumcarbonate ...

We investigated the effect of calcium carbonate on the oral bioavailability of gemifloxacin. Gemifloxacin was administered alone, 2 h before, simultaneously, or 2 h after calcium carbonate in 16 volunteers. Data for 320 mg of gemifloxacin alone were as follows: maximum concentration of drug in serum (C(max)),13 microg/ml; half-life, 7.33 h; and area under the concentration-time curve from 0 h t...

From chronic kidney disease (CKD) Stage 4 onwards, phosphate binders are needed in many patients to prevent the development of hyperphosphataemia, which can result in disturbed bone and mineral metabolism, cardiovascular disease and secondary hyperparathyroidism. In this review, we re-examine the use of magnesium-containing phosphate binders for patients with CKD, particularly as their use circ...

Surface facilities including tubing and valves at the oilfield have been plagued by mineral scale deposits, which are constitute of calcium carbonate (CaCO3). Penta-potassium diethylenetriaminepentaacetic acid salt (DTPA-K5) has a higher affinity for metal cations complexes during chelation process. The eight complexing sites (five carboxylate three amines) empower ion interactions. This work i...
