Intestinal Ca Absorption

The intestinal absorption of calcium (Ca) has been shown to depend on vitamin D3, 1,25-dihydroxyvitamin D3 [1,25(OH)2D3], and dietary phosphorus (P) concentration. This study was designed to evaluate the role of dietary P independent of vitamin D3 or 1,25(OH)2D3. Vitamin D-deficient rats were studied during dietary P restriction and were compared with control groups raised on a normal-phosphorus diet (NP). Balance studies were sued. Net intestinal Ca absorption was significantly lower with dietary P restriction compared with the NP group. This malabsorption of Ca was corrected by the administration of either D3 for 1,25(OH)2D3, despite hypophosphatemia. Everted gut sacs showed a marked reduction in the uptake of 45Ca in the duodenum, jejunum, and ileum during dietary P restriction. We concluded that dietary P concentration plays a major role in intestinal Ca absorption in the vitamin D-deficient rats. These findings suggest an effect of the low-phosphate diet on the vitamin D-dependent, Ca-transport mechanism.

Fasted adult male rats were used to study the effect of dietary proteins on intestinal alkaline phosphatase. Groups of animals were offered one of several proteins; lactalbumin, egg albumin, zein, gelatin, wheat gluten, casein, and vitellin. Control animals had cellulose fed to them. The rats were sacrificed six hours after they were given the different diets. Alkaline phosphatase determinations with intestinal homogenates indicated that the two phosphoproteins, casein and vitellin, elevated levels of the enzyme significantly above fasting levels. Possible interpretations of these findings are discussed.
