Total body water measurement in human adults with deuterium oxide.

The measurement of total body water in the human subject by deuterium oxide dilution; with a consideration of the dynamics of deuterium distribution.

The interpretation of fluctuations in body weight and changes in the state of hydration requires a knowledge of the total amount of water in the organism. This investigation has been directed towards the perfection of a method for measurement of the total body water in the human subject. The increasing availability and lowered cost of both stable and radioactive isotopes has made possible study...

The measurement of total body water in living pigs by deuterium oxide dilution and its relation to body composition.

I. Deuterium oxide was used to estmate body water in twenty-four pigs of widely differing body composition and of average weight 83.9 kg. 2. After infusion of the isotope, blood samples were collected every 30 min for 4 h. The resulting plasma was purified by a heat-distillation procedure, after which it was analysed for D,O by infrared spectroscopy. 3. Approximately 24 h after infusion of the ...

Total body water estimations in healthy men and women using bioimpedance spectroscopy: a deuterium oxide comparison

BACKGROUND Total body water (TBW) estimations have been used to estimate body composition, particularly fat-free mass, to aid in nutritional interventions, and to monitor hydration status. In the past, bioimpedance spectroscopy (BIS) devices have been used to estimate TBW. Previous investigations have examined the validity of the XiTRON 4000B (XiTRON Technologies) BIS device for estimating TBW....

The total body water and the water turnover in pregnancy studied with deuterium oxide as isotopic tracer.

Comparison of Muscle Mass, Total Body Water and Total Body Protein in Type II Diabetics with Healthy Matched Adults by Bioelectrical Impedance Analysis

Background: Bioelectrical impedance analysis (BIA) is a new and rapid technique to validate body composition. Several studies have used this technique to evaluate body compositions, such as muscle mass, in diabetic patients, but the results are very different. This may due the differences between diabetic patients and control group. Therefore, this study aimed to compare the muscle mass of diab...
