Effect of Magnesium on Biomineralization of Bone

The phosphorus content, molar radio of calcium and phosphorus and the effects of magnesium on calcium content in chicken bones were studied, comparing with different three groups which was fed with magnesium salt. The result showed that calcium content and phosphorus content of experimental groups have raised compared with those of normal group and the molar radio of calcium and phosphorus of experimental groups decreased with the extension of feeding time. In addition, the molar radio of calcium and phosphorus of experimental group, including liquid group and solid group which was fed with magnesium salt, decreased slower than that of normal group. A process that mixture of containing-phosphate and consisted of non-phosphate calcium salt changed into hydroxyapatite, calcium phosphate and calcium hydrophosphate, had happened.
