[Interrelationship of calcium and magnesium in the case of a varying magnesium content in the diet of jaw fracture patients].

In 12 patients with jaw-bones fractures an investigation of calcium and magnesium metabolism was carried out with a view of elucidating its possible relation to the course of repair of the bone tissue. A reciprocal dependence in the calcium and magnesium ions exchange in lesions of the jaws and an intensified accumulation of these ions by the time of the initial formation of the secondary callus were revealed. Investigations have confirmed the important role of magnesium in the metabolism of the bone tissue and a study of two diets with different magnesium content justified recommending its daiy allowance of about 550 mg for the given patients' population.
