The purpose of this study was to examine the effects of a doubling in water intake on the total body water measured by the tritium dilution technique. Overdrinking was obtained by presenting tap water and sweet water to the rats. Total body water was measured twice, tritium dilution vs. dessication. Body water volumes differed between the two methods but not between the two groups. Thus the isotopic dilution technique can be used to measure total body water regardless of the flux of fluid through the subject.
本研究的目的是通过氚稀释技术来检测饮水量加倍对全身水含量的影响。通过给大鼠提供自来水和甜水来实现过量饮水。全身水含量通过两种方式测量了两次，即氚稀释法和干燥法。两种方法测得的身体水含量存在差异，但两组之间并无差异。因此，无论通过受试者的液体通量如何，同位素稀释技术均可用于测量全身水含量。
