[Deficient nickel supply and the content of calcium, magnesium and phosphorus inthe bone of growing rats].
Based upon studies on Ni deficiency with marked changes in intermediary metabolism, the recent investigation examined the extent to which deficient Ni supply affects the content of calcium, magnesium and phosphorus in rat femurs. In Ni deficiency the content of calcium and phosphorus was reduced, in the case of calcium even more so than accounted for by the decrease in bone weight. The result was Ca : P ratio of 1.8 : 1 in Ni deficiency compared with 2.0 : 1 in control animals. In the case of magnesium, however, the Mg concentration was increased by 45% in the bone fresh matter of the deficient animals. The reduced Ca retention in the bone is accordingly contrasted by an enhanced deposition of magnesium.
