On the Metabolism of Mineral Elements in Infantile Period

Part XV, On the Metabolism of Mineral Elements in the Rachitic Infants and Animals, and the Summary and Discussions on the Metabolism of Mineral Elements in Relation With the Nutritive Conditions.

Abstract

Even though the greater amounts of calcium and phosphorous taken by the rachitic infants and animals from their mother's milk and the diets than the nomals, their absorption or retention in the body was smaller and also their metabolisms in the body became more diffcult.
However, potassium and sodium, showed sometimes the reverse tendencies comparing with those of calcium and phosphorous.The amounts of total and di alyzable calcium and also phosphorous were greater in the mother, s milk taken by the good nutritive infants but the excretions of calcium, phosphorous, iron, and copper were generally smaller than those of malnutritive infants.
