The absorption of calcium from the intestine.
From studies of loss of radiocalcium from the intestinal lumen of rats it was well known that the absorption of calcium occurs mainly in the proximal small intestine (Harrison & Harrison, 195 I ; Nicolaysen, 195 I) . A similar observation was made in the pig (Moore & Tyler, 1955). In the chick, according to Coates & Holdsworth (1961), however, calcium absorption appeared to occur over the whole...

متن کاملLead and iron absorption from rat small intestine: the effect of dietary Fe deficiency.
1. When lead is administered in drinking-water iron-deficient rats retain more Pb than Fe-replete rats (Six & Goyer, 1972; Klauder & Petering, 1975). In the present study the relationship between the absorption of Pb and Fe was investigated. 2. Adult male rats were transfered to a milk-based diet fed with or without supplementary Fe (180 mg Fe/kg as ferrous sulphate). After 7--9 d the absorptio...
متن کاملAlcohol and absorption from the small intestine
Absorption of electrolytes from the intestinal lumen into the blood stream involves, predominantly, the process of active transport. Energy for cellular metabolism derives from the splitting of the high energy phosphate bond of adenosine triphosphate (ATP) by the enzyme adenosine triphosphatase (ATPase), (Brooks, 1973). Ethanol has been shown to affect the ATP content in several tissues and it ...
متن کاملIn vivo absorption of calcium carbonate and magnesium oxide from the large intestine in rats.
This study was conducted to evaluate the ability of the large intestine to absorb calcium (Ca) and magnesium (Mg) from their sparingly water-soluble salts, and also to determine whether fructooligosaccharides (FOS) stimulate the absorption of these minerals in rat large intestine in vivo. Rats were fed Ca- and Mg-free diets with and without 5% FOS. An aqueous suspension of CaCO3 and MgO was inf...
