猪骨的综合应用能收到较大的经济效益,是一项值得重视和研究的工作。本文用大白鼠做了从猪骨中制备的药用磷酸氢钙、食用磷酸氢钙(实际是一个产品,以下简称骨钙盐)的急性毒性实验,以观察骨钙盐应用于人体时的安全性;通过代谢实验,测定了大白鼠对其中钙质的吸收率和利用率。现报告如下。材料与方法一、动物:取自本院动物室的杂交大白鼠,代谢实验选用雄性大白鼠。实验前的体重 Comprehensive application of pig bone can receive greater economic benefits, is a work worthy of attention and research. In this paper, mice made from pig bone medicinal dicalcium phosphate, edible calcium hydrogen phosphate (actually a product, hereinafter referred to as bone calcium salt) of acute toxicity experiments to observe the safety of bone calcium salts used in humans The metabolic rate and utilization rate of calcium in rats were determined by metabolic test. The report is as follows. Materials and methods First, animals: hybrid rats taken from the animal room of our hospital, male rats used for metabolism experiments. Weight before experiment
