title: [Effect of protein and vitamin D deficiency on several indices of calcium metabolism].
abstract: The effect of the proteins and vitamin "D" deficiency in the diet on the formation of the calcium-binding protein (CaBP), absorption of calcium in the small intestine and on the Ca and P content in blood serum of rats was studied. The resulting data demonstrate that hypovitaminosis "D" leads to a significantly reduced formation of CaBP, diminished absorption of tagged C35 in the small intestine and Ca and P level in the blood serum. The decline of these values is observed in cases of protein deficiency and with rising protein shortage these changes become more marked. A further fall of the CaBP level, of the labelled calcium absorption and of the serumal Ca and P is observed with simultaneous action on the organism of the proteins and vitamin "D" deficiency.
