摘要

Water (H 2O) is the most abundant and important molecule of life. Natural water contains small amount of heavy isotopes. Previously, few animal model studies have shown that the isotopic composition of body water could play important roles in physiology and pathophysiology. Here we study the stable isotopic ratios of hydrogen (δ 2H) and oxygen (δ 18O) in human blood plasma. The stable isotopic ratio is defined and determined by δ sample = [(R sample/R STD)-1] * 1000, where R is the molar ratio of rare to abundant, for example, 18O/ 16O. We observe that the δ 2H and the δ 18O in human blood plasma are associated with the human renal functions. The water isotope ratios of the δ 2H and δ 18O in human blood plasma of the control subjects are comparable to those of the diabetes subjects (with healthy kidney), but are statistically higher than those of the end stage renal disease subjects (p2H and δ 18O) in blood plasma of body water may shed light on a novel assessment of renal functions.
