Abstract The in vitro permeation and absorption of calcium ions across the small intestine were measured at different concentrations of calcium gluconate solutions (1.0, 10.0 and 20.0 mM) with or without prolactin. The calcium ions permeated through the small intestine from a donor environment to an acceptor environment that mimicked the conditions in the stomach to ileum segment of the digestive tract. The permeation and absorption of calcium were directly dependent on the calcium concentration of the solutions. At 10 and 20 mM permeation was significantly higher than that at 1.0 mM (p<0.05). In the presence of prolactin both permeation and absorption increase considerably. At the lowest concentration (1.0 mM) simulating calcium deficiency, there was compensation by the small intestine, suggesting that such deficiency stimulates its mobilization from intestinal tissue. Prolactin enhances the calcium mobilization process even at sufficient calcium intakes. It is suggested that prolactin takes part in regulation of calcium homeostasis in the organism.
