ALTERNATIVE ASSESSMENT OF INTESTINAL CALCIUM ABSORPTION

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 该项目的目标是开发一种使用双稳定钙同位素测量肠道钙吸收分数的简单方法，该方法不需要多次采血或24小时尿液采集。 要检验的假设是：口服和静脉注射钙的稳定同位素的血清水平的稳态比率代表肠道钙吸收的分数。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The objective of this project is to develop an easy method for measuring fractional intestinal calcium absorption using dual stable Ca isotopes that does not involve multiple blood sampling or a 24 hr urine collection. The hypothesis to be tested is: the steady state ratio, of serum levels of the stable isotopes of calcium given orally and intravenously, represents fractional intestinal calcium absorption.
