ALTERNATIVE ASSESSMENT OF INTESTINAL CALCIUM ABSORPTION

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。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.
