The intestinal calcium and phosphate transport under conditions of experimental hypercalcemia

The intestinal calcium and phosphate transport under conditions of experimental hypercalcemia. Acta Physiol. Pol., 1977, 28 (2): 127--134. Intestinal calcium and phosphate transport was examined in various segments of small intestine under two differently processed hypercalcemic conditions. The analysis of the serum calcium and phosphate level changes, showed the increasing serum calcium values without any concomitant change in the serum phosphate concentration during the course of the experiment. The observed discrepancy of the intestinal phosphate transport when compared the in vitro and in vivo studies, suggests the presence of phosphate transport regulatory mechanism acting on the intestinal level.
