[Studies on the influence of riboflavin intake to osteogenesis in rats]

Influence of an intake of the riboflavin that exerts upon osteogenesis in this research, was examined by a nutritional methods. It search the condition of femur in rats they reared and given three type riboflavin dosage, namely, sufficient riboflavin, few deficient riboflavin and administered sufficient after few deficient riboflavin. As a result, an influence of riboflavin dosage was not recognized about each of the body weight, food intake, and weight and length of femur. In other words, a deficiency symptom was not observed seemingly in the rat that given riboflavin deficiency diet. Also, the calcium contents in the femur decreased significantly by the deficiency of riboflavin. And, the low value was shown the even in the rat that administered sufficient fibroflavin later. Furthermore, even breaking force of the femur decreased by the deficiency of riboflavin.
